Description

Technical Field

[0001] This application relates to the field of positioning technology, and in particular to an uplink reference signal association method and communication device. Background Technology

[0002] In mobile communication systems, locating terminal devices is a crucial function. Current positioning technologies include downlink positioning and uplink positioning. Uplink positioning refers to the process where the terminal device sends an uplink reference signal to the network device. This uplink reference signal can be, for example, a sounding reference signal (SRS). The network device measures the uplink reference signal and sends the measurement result to the positioning management device. The positioning management device then determines the terminal device's location information based on the measurement result.

[0003] However, in practice, it has been found that the positioning accuracy of current positioning technologies in low-frequency communication systems is not high. The main reason is that the maximum bandwidth of a single uplink reference signal in low-frequency NR communication systems is only 100MHz, and the accuracy of timing-based ranging positioning methods is directly related to bandwidth. Generally speaking, the larger the bandwidth, the higher the ranging accuracy. Therefore, how to enhance the existing uplink reference signal configuration structure to achieve a large-bandwidth uplink reference signal configuration, thereby improving positioning accuracy, is a problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides an uplink reference signal association method and communication device, which can realize the configuration of a large bandwidth uplink reference signal.

[0005] In a first aspect, this application provides an association method for uplink reference signals, the method comprising: a first network device generating first configuration information, the first configuration information indicating the association relationship between uplink reference signals simultaneously transmitted on different carriers; uplink reference signals with association sharing an antenna port or uplink reference signals with association having a phase difference; and the first network device sending the first configuration information to a terminal device.

[0006] In the method described in the first aspect, the network side can configure the terminal device to share an antenna port among uplink reference signals or to have a phase difference between uplink reference signals. Sharing an antenna port among multiple uplink reference signals means that the multiple uplink reference signals experience the same identical channel, which can be equivalently viewed as the terminal device transmitting a new uplink reference signal, the bandwidth of which is equivalent to the sum of the bandwidths of the multiple uplink reference signals. Therefore, sharing an antenna port among multiple uplink reference signals can expand the signal bandwidth. Thus, by configuring the terminal device to share an antenna port among uplink reference signals, a large-bandwidth uplink reference signal configuration can be achieved. By configuring the terminal device to have a phase difference between uplink reference signals, the network device can estimate the phase difference between these uplink reference signals and then compensate the channel phase of the uplink reference signals using this phase difference, thereby enabling the multiple uplink reference signals to share an antenna port to expand the signal bandwidth. Therefore, by configuring the terminal device to have a phase difference between uplink reference signals, a large-bandwidth uplink reference signal configuration can also be achieved.

[0007] In one possible implementation, a first network device generates second configuration information indicating the correlation between uplink reference signals simultaneously transmitted on different carriers; the first network device then sends the second configuration information to a positioning management device. Based on this possible implementation, the second configuration information can indicate the correlation between uplink reference signals simultaneously transmitted on different carriers to the positioning management device, thereby allowing the positioning management device to indicate the correlation between uplink reference signals simultaneously transmitted on different carriers to the second network device. Consequently, the second network device can perform joint measurements on the correlated uplink reference signals to obtain measurement results.

[0008] In one possible implementation, the first configuration information and / or the second configuration information further indicate that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a fixed phase difference. Based on this possible implementation, the type of association can be flexibly configured for the terminal device and / or the positioning management device.

[0009] In one possible implementation, during the transmission of correlated uplink reference signals by the terminal device, the phase difference between the correlated uplink reference signals is a fixed value. Optionally, the small change in the phase difference between the correlated uplink reference signals during transmission can also be understood as the phase difference remaining constant during transmission. By keeping the phase difference between the correlated uplink reference signals constant during transmission, the terminal device can more accurately estimate the phase difference between them.

[0010] In one possible implementation, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to the same antenna port. That is, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to a shared antenna port.

[0011] In one possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers. That is, the first configuration information can indicate the association between uplink reference signals transmitted simultaneously on different carriers by indicating the association between these resources, thus accurately indicating the association between them. For example, if the first configuration information indicates that uplink reference signal resource 1 and uplink reference signal resource 2 transmitted simultaneously on different carriers are associated, then the first configuration information is equivalent to indicating that the uplink reference signal corresponding to uplink reference signal resource 1 and the uplink reference signal corresponding to uplink reference signal resource 2 are associated.

[0012] Optionally, the first configuration information includes configuration information for multiple carriers. The carrier configuration information includes the carrier's index and the configuration information of the bandwidth portion (BWP) within that carrier. The BWP configuration information includes the BWP's index and the configuration information of the uplink reference signal resource set within that BWP. The uplink reference signal resource set configuration information includes the uplink reference signal resource set's index and the configuration information of the uplink reference signal resources within that uplink reference signal resource set. The first configuration information indicating the association between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following three specific ways:

[0013] ① The configuration information of the first uplink reference signal resource set also includes at least one first index information. This first index information includes the index of the second carrier, the index of the second BWP in the second carrier, and the index of the second uplink reference signal resource set in the second BWP. This indicates that the uplink reference signal resources transmitted simultaneously in the first uplink reference signal resource set and at least one second uplink reference signal resource set are associated. The first uplink reference signal resource set and at least one second uplink reference signal resource set are resource sets on different carriers configured by the first configuration information. Method ① is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between uplink reference signal resource sets on different carriers, which helps to save signaling overhead.

[0014] ② The configuration information of the first BWP also includes at least one second index, which includes an index of the second carrier and an index of the second BWP within the second carrier. This indicates that the uplink reference signal resources transmitted simultaneously in the first BWP and at least one second BWP are associated. The first BWP and the second BWP are BWPs on different carriers configured by the first configuration information. Method ② is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between BWPs on different carriers, which helps to save signaling overhead.

[0015] ③ The configuration information of the first carrier also includes an index of at least one second carrier to indicate that the uplink reference signal resources transmitted simultaneously on the first carrier and at least one second carrier are associated. The first carrier and the second carrier are different carriers configured in the first configuration information. Method ③ is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between different carriers, which helps to save signaling overhead.

[0016] Optionally, the index of the second carrier may include one or more of the following: the index of the serving cell in which the second carrier is located, and indication information for indicating that the second carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0017] Optionally, the uplink reference signal resource is the sounding reference signal (SRS) resource; the configuration information of the first BWP also includes the SRS configuration (SRS-Config), which includes at least one second index information.

[0018] In another possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the first configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, and will not be repeated here. For example, if the first configuration information indicates that a first uplink reference signal resource set is associated with at least one second uplink reference signal resource set, then there is an association between the first uplink reference signal resource set and the uplink reference signals transmitted simultaneously in at least one second uplink reference signal resource set. Using this possible implementation to indicate the association between uplink reference signals transmitted simultaneously on different carriers helps to save signaling overhead.

[0019] In another possible implementation, the first configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the correlation between BWPs on different carriers. The specific implementation of the first configuration information indicating the correlation between BWPs on different carriers can be found in the description of method ② above, and will not be repeated here. For example, if the first configuration information indicates that a first BWP is correlated with at least one second BWP, then there is a correlation between the first BWP and the uplink reference signals transmitted simultaneously in at least one second BWP. Using this possible implementation to indicate the correlation between uplink reference signals transmitted simultaneously on different carriers helps to save signaling overhead.

[0020] In another possible implementation, the first configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the correlation between different carriers. The specific implementation of the first configuration information indicating the correlation between different carriers can be found in the description of method ③ above, and will not be repeated here. For example, if the first configuration information indicates that the first carrier is correlated with at least one second carrier, then the first carrier is correlated with the uplink reference signals transmitted simultaneously on at least one second carrier. Using this possible implementation to indicate the correlation between uplink reference signals transmitted simultaneously on different carriers helps to save signaling overhead.

[0021] In one possible implementation, the second configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers. That is, the second configuration information can indicate the association between uplink reference signals transmitted simultaneously on different carriers by indicating the association between these resources, thus accurately indicating the association between them. For example, if the second configuration information indicates that uplink reference signal resource 1 and uplink reference signal resource 2 transmitted simultaneously on different carriers are associated, then the second configuration information is equivalent to indicating that the uplink reference signal corresponding to uplink reference signal resource 1 and the uplink reference signal corresponding to uplink reference signal resource 2 are associated.

[0022] Optionally, the second configuration information includes configuration information for multiple carriers. The carrier configuration information includes the carrier index and the configuration information of the uplink reference signal resource set within that carrier. The uplink reference signal resource set configuration information includes the uplink reference signal resource set index and the configuration information of the uplink reference signal resources within the uplink reference signal resource set. The second configuration information indicating the association between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following two specific ways:

[0023] ① The configuration information of the third uplink reference signal resource set also includes at least one third index information. This third index information includes the index of the fourth carrier and the index of the fourth uplink reference signal resource set in the fourth carrier, indicating that the third uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one fourth uplink reference signal resource set are associated. The third uplink reference signal resource set and the at least one fourth uplink reference signal resource set are resource sets on different carriers configured by the second configuration information. Method ① is equivalent to indicating the association between uplink reference signal resource sets transmitted on different carriers by indicating the association between them, which helps to save signaling overhead.

[0024] ② The configuration information of the third carrier also includes an index of at least one fourth carrier to indicate that the uplink reference signal resources transmitted simultaneously on the third carrier and at least one fourth carrier are associated. The third carrier and the at least one fourth carrier are different carriers configured in the second configuration information. Method ② is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between different carriers, which helps to save signaling overhead.

[0025] Optionally, the index of the fourth carrier may include one or more of the following: the index of the serving cell in which the fourth carrier is located, and indication information for indicating that the fourth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0026] In another possible implementation, the second configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the second configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, which describes the association between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the second configuration information indicates that a third uplink reference signal resource set is associated with at least one fourth uplink reference signal resource set, then there is an association between the third uplink reference signal resource set and the uplink reference signals transmitted simultaneously in at least one fourth uplink reference signal resource set. Using this possible implementation to indicate the association between uplink reference signals transmitted simultaneously on different carriers helps to save signaling overhead.

[0027] In another possible implementation, the second configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the correlation between different carriers. The specific implementation of the second configuration information indicating the correlation between different carriers can be found in the description of method ② above, which describes the correlation between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the second configuration information indicates that the third carrier is correlated with at least one fourth carrier, then the third carrier is correlated with the uplink reference signals transmitted simultaneously on at least one fourth carrier. Using this possible implementation to indicate the correlation between uplink reference signals transmitted simultaneously on different carriers helps to save signaling overhead.

[0028] In one possible implementation, the first network device receives capability information reported by the terminal device. This capability information indicates whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously via a shared antenna port, or whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference. Based on this possible implementation, the first network device can accurately determine how to configure uplink reference signal resources for the terminal device based on the terminal device's capability information. Alternatively, the first network device can perform other operations based on the terminal device's capability information.

[0029] In one possible implementation, the reporting granularity of capability information is per frequency band, per frequency band group, per frequency band within a frequency band group, or per frequency band subset within a frequency band group. Based on this possible implementation, the capability information of terminal devices can be reported at a relatively fine granularity.

[0030] In one possible implementation, the first network device receives first information sent by the positioning management device; the first information is used to request the first network device to configure an uplink reference signal with a preset bandwidth, the preset bandwidth being greater than 100 MHz or greater than 400 MHz; or, the first information is used to request the first network device to configure the association relationship between uplink reference signals transmitted simultaneously on different carriers. Based on this possible implementation, the positioning management device can request the first network device to configure the association relationship between uplink reference signal resources transmitted simultaneously on different carriers, either implicitly or explicitly.

[0031] In one possible implementation, the first information is further used to request that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference. Based on this possible implementation, the positioning management device can recommend the type of association that should be configured to the first network device based on the capability information of the network device used to measure the uplink reference signal, which helps the first network device to reasonably configure the type of association.

[0032] Secondly, this application provides an association method for uplink reference signals, the method comprising: a terminal device receiving first configuration information, the first configuration information indicating the association relationship between uplink reference signals simultaneously transmitted on different carriers; the associated uplink reference signals sharing an antenna port or the associated uplink reference signals having a phase difference; and the terminal device transmitting the associated uplink reference signals.

[0033] In one possible implementation, the first configuration information also indicates that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference.

[0034] In one possible implementation, during the transmission of correlated uplink reference signals by the terminal device, the phase difference between the correlated uplink reference signals is a fixed value. Optionally, the small change in the phase difference between the correlated uplink reference signals during the transmission of correlated uplink reference signals by the terminal device can also be understood as the phase difference between the correlated uplink reference signals being a fixed value.

[0035] In one possible implementation, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to the same antenna port. That is, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to a shared antenna port.

[0036] In one possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers.

[0037] Optionally, the first configuration information includes configuration information for multiple carriers. The carrier configuration information includes the carrier's index and the configuration information of the bandwidth portion (BWP) within that carrier. The BWP configuration information includes the BWP's index and the configuration information of the uplink reference signal resource set within that BWP. The uplink reference signal resource set configuration information includes the uplink reference signal resource set's index and the configuration information of the uplink reference signal resources within that uplink reference signal resource set. The first configuration information indicating the association between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following three specific ways:

[0038] ① The configuration information of the first uplink reference signal resource set also includes at least one first index information. The first index information includes the index of the second carrier, the index of the second BWP in the second carrier, and the index of the second uplink reference signal resource set in the second BWP, so as to indicate that the uplink reference signal resources transmitted simultaneously in the first uplink reference signal resource set and at least one second uplink reference signal resource set are associated. The first uplink reference signal resource set and at least one second uplink reference signal resource set are resource sets on different carriers configured by the first configuration information.

[0039] ② The configuration information of the first BWP also includes at least one second index information, which includes the index of the second carrier and the index of the second BWP in the second carrier, to indicate that the uplink reference signal resources transmitted simultaneously in the first BWP and at least one second BWP are associated. The first BWP and at least one second BWP are BWPs on different carriers configured by the first configuration information.

[0040] ③ The configuration information of the first carrier also includes an index of at least one second carrier to indicate that the uplink reference signal resources transmitted simultaneously in the first carrier and at least one second carrier are associated, and the first carrier and at least one second carrier are different carriers configured in the first configuration information.

[0041] Optionally, the index of the second carrier may include one or more of the following: the index of the serving cell in which the second carrier is located, and indication information for indicating that the second carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0042] Optionally, the uplink reference signal resource is the sounding reference signal (SRS) resource; the configuration information of the first BWP also includes the SRS configuration (SRS-Config), which includes at least one second index information.

[0043] In another possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the first configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, which describes the association between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the first configuration information indicates that a first uplink reference signal resource set is associated with at least one second uplink reference signal resource set, then there is an association between the first uplink reference signal resource set and the uplink reference signals transmitted simultaneously in at least one second uplink reference signal resource set.

For example, if the first configuration information indicates that the first carrier is associated with at least one second carrier, then the first carrier is associated with the uplink reference signals transmitted simultaneously on at least one second carrier.

[0046] In one possible implementation, the terminal device reports capability information to the first network device, which indicates whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously via a common antenna port, or whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference.

[0047] In one possible implementation, the terminal device reports capability information to the positioning management device. This capability information is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously via a common antenna port, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference.

[0048] In one possible implementation, the reporting granularity of capability information is per-band reporting, or per-band group reporting, or per-band reporting within a per-band group, or per-band group subset reporting within a per-band group.

[0049] In one possible implementation, the terminal device transmits uplink reference signals with the aforementioned correlation as follows: if the terminal device supports the simultaneous transmission of multiple uplink reference signals sharing an antenna port, or supports the simultaneous transmission of multiple uplink reference signals having a phase difference, then the terminal device transmits uplink reference signals with a correlation, ensuring that the correlated uplink reference signals share an antenna port or have a phase difference. Based on this possible implementation, it is advantageous for the terminal device to successfully transmit uplink reference signals.

[0050] Thirdly, this application provides an association method for uplink reference signals, the method comprising: a positioning management device receiving second configuration information sent by a first network device, the second configuration information indicating the association relationship between uplink reference signals simultaneously transmitted on different carriers; the associated uplink reference signals sharing an antenna port or the associated uplink reference signals having a phase difference; and the positioning management device sending third configuration information to a second network device, the third configuration information indicating the association relationship between uplink reference signals simultaneously transmitted on different carriers.

For example, if the second configuration information indicates that a third uplink reference signal resource set is associated with at least one fourth uplink reference signal resource set, then there is an association between the third uplink reference signal resource set and the uplink reference signals transmitted simultaneously in at least one fourth uplink reference signal resource set.

The uplink reference signal resource set configuration information includes the uplink reference signal resource set's index and the configuration information for the uplink reference signal resources within the set. The third configuration information indicating the association between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following two specific ways:

[0063] ① The configuration information of the fifth uplink reference signal resource set also includes at least one fourth index information. The fourth index information includes the index of the sixth carrier and the index of the sixth uplink reference signal resource set in the sixth carrier, so as to indicate that the uplink reference signal resources transmitted simultaneously in the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are associated. The fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are resource sets on different carriers configured by the third configuration information.

The specific implementation of the third configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, which describes the association between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the third configuration information indicates that the fifth uplink reference signal resource set is associated with at least one sixth uplink reference signal resource set, then the uplink reference signals transmitted simultaneously in the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are associated.

The specific implementation of the third configuration information indicating the correlation between different carriers can be found in the description of method ② above, which describes the correlation between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the third configuration information indicates that the fifth carrier is correlated with at least one sixth carrier, then the uplink reference signals transmitted simultaneously on the fifth carrier and at least one sixth carrier are correlated.

[0068] In one possible implementation, the positioning management device sends first information to the first network device; the first information is used to request the first network device to configure an uplink reference signal with a preset bandwidth, the preset bandwidth being greater than 100 MHz, or the preset bandwidth being greater than 400 MHz; or, the first information is used to request the first network device to configure the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0069] In one possible implementation, the first information is also used to request that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference.

[0070] In one possible implementation, the positioning management device receives capability information reported by the terminal device, which indicates whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously via a common antenna port, or whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference.

[0071] In one possible implementation, the reporting granularity of capability information is per-band reporting, or per-band group reporting, or per-band reporting within a per-band group, or per-band group subset reporting within a per-band group.

[0072] In one possible implementation, the positioning management device receives measurement results sent by a second network device. These measurement results are obtained by the second network device from measurements of correlated uplink reference signals. The measurement results include an index of the resource set containing the correlated uplink reference signals and / or an index of the carrier containing the correlated uplink reference signals. Based on this possible implementation, the positioning management device can better determine which uplink reference signal resources the measurement results were based on.

[0073] Fourthly, this application provides an association method for uplink reference signals, the method comprising: a second network device receiving third configuration information, the third configuration information indicating the association relationship between uplink reference signals simultaneously transmitted on different carriers; the associated uplink reference signals sharing an antenna port or the associated uplink reference signals having a phase difference; and the second network device measuring the associated uplink reference signals.

[0074] In one possible implementation, the third configuration information also indicates that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference.

[0075] In one possible implementation, during the process of the terminal device sending correlated uplink reference signals, the phase difference between the correlated uplink reference signals is a fixed value.

[0076] In one possible implementation, when the uplink reference signal has multiple antenna ports, the same antenna port number of the associated uplink reference signals corresponds to the same antenna port.

[0077] In one possible implementation, the third configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers.

[0078] Optionally, the third configuration information includes configuration information for multiple carriers. The carrier configuration information includes the carrier's index and the configuration information for the uplink reference signal resource set within that carrier. The uplink reference signal resource set configuration information includes the uplink reference signal resource set's index and the configuration information for the uplink reference signal resources within the set. The third configuration information indicating the association between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following two specific ways:

[0079] ① The configuration information of the fifth uplink reference signal resource set also includes at least one fourth index information. The fourth index information includes the index of the sixth carrier and the index of the sixth uplink reference signal resource set in the sixth carrier, so as to indicate that the uplink reference signal resources transmitted simultaneously in the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are associated. The fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are resource sets on different carriers configured by the third configuration information.

[0080] ② The configuration information of the fifth carrier also includes an index of at least one sixth carrier to indicate that the uplink reference signal resources transmitted simultaneously in the fifth carrier and at least one sixth carrier are associated, and the fifth carrier and at least one sixth carrier are different carriers configured in the third configuration information.

[0081] Optionally, the index of the sixth carrier may include one or more of the following: the index of the serving cell in which the sixth carrier is located, and indication information for indicating that the sixth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0082] In another possible implementation, the third configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the third configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, which describes the association between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the third configuration information indicates that the fifth uplink reference signal resource set is associated with at least one sixth uplink reference signal resource set, then the uplink reference signals transmitted simultaneously in the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are associated.

[0083] In another possible implementation, the third configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the correlation between different carriers. The specific implementation of the third configuration information indicating the correlation between different carriers can be found in the description of method ② above, which describes the correlation between uplink reference signal resources transmitted simultaneously on different carriers, and will not be repeated here. For example, if the third configuration information indicates that the fifth carrier is correlated with at least one sixth carrier, then the uplink reference signals transmitted simultaneously on the fifth carrier and at least one sixth carrier are correlated.

[0084] In one possible implementation, the second network device sends measurement results to the positioning management device. The measurement results are obtained by the second network device from measuring the related uplink reference signals. The measurement results include the index of the resource set where the related uplink reference signals are located and / or the index of the carrier where the related uplink reference signals are located.

[0129] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0130] The terms "first" and "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of operations or units is not limited to the listed operations or units, but may optionally include operations or units not listed, or may optionally include other operations or units inherent to these processes, methods, products, or apparatuses.

[0131] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0132] In this application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the correspondence between corresponding objects, indicating that there can be three relationships.

[0133] To better understand the solution provided in this application, the system architecture of this application will be introduced below:

[0134] The method provided in this application can be applied to various communication systems, such as Internet of Things (IoT) systems, narrowband Internet of Things (NB-IoT) systems, long term evolution (LTE) systems, 5th generation (5G) communication systems, LTE and 5G hybrid architectures, 5G new radio (NR) systems, and new communication systems that will emerge in the future development of communication.

[0135] Please see Figure 1 , Figure 1 This is a schematic diagram of a system architecture provided in an embodiment of this application. For example... Figure 1 As shown, the system architecture includes terminal equipment, a first network device, a second network device, and a positioning management device.

[0136] The terminal device involved in the embodiments of this application is an entity on the user side used to receive or transmit signals. The terminal device can be a device that provides voice and / or data connectivity to the user, such as a handheld device with wireless connectivity, an in-vehicle device, etc. The terminal device can also be other processing devices connected to a wireless modem. The terminal device can communicate with a radio access network (RAN). The terminal device can also be referred to as a wireless terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE), etc. The terminal device can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or in-vehicle mobile device that exchanges voice and / or data with the radio access network. For example, the terminal device can also be a personal communication service (PCS) telephone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), and other devices. Common terminal devices include, for example, automobiles, drones, robotic arms, mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), and wearable devices such as smartwatches, smart bracelets, and pedometers, but the embodiments in this application are not limited to these.

[0137] The network device in this application embodiment can be an access network device or other network devices. A network device is an entity on the network side used to transmit or receive signals. It can be used to convert received air frames to and from network protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, which may include IP networks, etc. The network device can also coordinate the attribute management of the air interface. For example, the network device can be an evolved Node B (eNB or e-NodeB) in LTE, a new radio controller (NR controller), an ng-eNB, a gNode B (gNB) in a 5G system, a centralized unit, a new radio base station, a remote radio module, a micro base station, a relay, a distributed unit, or any other wireless access device, but this application embodiment is not limited to these.

[0138] The first network device can be the serving access network device of the terminal device. The second network device is an access network device used to measure the uplink reference signal transmitted by the terminal device. The second network device may include one or more cells, and each cell may include one or more transmission reception points (TRPs) or one or more reception points (RPs). The second network device can specifically measure the uplink reference signal through a TRP or an RP. Optionally, the second network device can also be the first network device, or the second network device may be different from the first network device.

[0139] Location management equipment is a network-side device used to determine the location information of terminal devices. Location management equipment can be a location management function (LMF) entity, an evolved serving mobile location center (E-SMLC), or other devices that can be used to determine the location information of terminal devices.

[0140] In one possible implementation, Figure 1 Based on the system architecture shown, other devices may also be included. For example, Figure 2 This is a schematic diagram of another system architecture. Figure 2Taking the terminal device as UE, the first network device as gNB, the second network device as ng-eNB, and the location management device as LMF as an example. Figure 2 As shown, the system architecture may also include an access management function (AMF) entity. The AMF entity is a control plane network function provided by the operator's network, responsible for access control and mobility management of terminal devices accessing the operator's network, including functions such as mobility state management, allocation of temporary user identities, authentication, and authorization. Optionally, the system architecture may also include a user plane location platform (SUPL, SLP) and an enhanced services mobile location center (E-SMLC) entity. This application embodiment only describes network devices strongly related to the location information determination method proposed in this application; other related network devices are not described in detail here.

[0141] In this embodiment, the uplink reference signal is a reference signal sent by the terminal device to the access network device (such as a base station) on the network side. The uplink reference signal can be a sounding reference signal (SRS) or other uplink reference signals. The following uses SRS as an example to introduce the positioning technologies supported by the uplink reference signal:

[0142] 1. Uplink Relative Time of Arrival (UL-TDOA) Positioning Technology. In this positioning technology, each cell sends SRS measurements of the uplink relative time of arrival (UL-RTOA) to the terminal equipment and reports the measurement results to the LMF. The LMF uses the measurement results to locate the terminal equipment.

[0143] 2. Uplink Angle of Arrival (UL-AOA) Positioning Technology. In this positioning technology, each cell sends SRS measurements of the UL-AoA to the terminal equipment and reports the measurement results to the LMF. The LMF then uses the measurement results to locate the terminal equipment.

[0144] 3. Multi-round trip time (Multi-RTT) positioning technology. In this positioning technology, the terminal equipment measures the UE-RxTxTimeDiff (UE RxmeDiffime.received) from the PRS transmitted by each cell and reports the measurement results to the LMF; each cell measures the gNB-RxTxTimeDiff (gNB Rx–Tx time difference) from the SRS transmitted by the terminal equipment and reports the measurement results to the LMF. The LMF uses the measurement results to locate the terminal equipment.

[0145] In the above positioning technologies, SRS can be measured by the TRP or RP in each cell. The following explanation uses TRP measurement of SRS as an example. The following sections introduce several concepts related to SRS configuration, such as... Figure 3 As shown:

[0146] 1. Serving Cell / Carrier. Each serving cell may include one or two carriers. When a serving cell includes two carriers, one carrier is a normal uplink carrier and the other is an auxiliary uplink carrier (SUL). Each carrier includes one or more BWPs.

[0147] 2. BWP. A BWP is a portion of the bandwidth on a carrier, corresponding to a set of resource blocks (RBs), subcarrier spacing, and cyclic prefix (CP) type. In Rel-15 and Rel-16, multiple BWPs can be configured on a carrier, but at most one BWP can be active on a carrier at any given time. The terminal transmits data, uplink control, and SRS on the active BWP. One or more SRS resource sets can be configured on a BWP.

[0148] 3. SRS Resource Set. An SRS resource set contains one or more SRS resources. The SRS resources within an SRS resource set have the same periodicity and SRS power control parameters.

[0149] 4. SRS Resources. SRS resources are the smallest unit of SRS configuration, and one SRS resource corresponds to one SRS transmission beam.

[0150] Currently, positioning accuracy in low-frequency communication systems is not high. This is primarily because the maximum bandwidth of a single uplink reference signal in a low-frequency NR communication system is only 100MHz, and the accuracy of timing-based ranging positioning methods is directly related to bandwidth. Generally, the larger the bandwidth, the higher the ranging accuracy. Therefore, how to enhance the existing uplink reference signal configuration structure to achieve a large-bandwidth uplink reference signal configuration, thereby improving positioning accuracy, is a pressing issue that needs to be addressed.

[0151] To achieve the configuration of a high-bandwidth uplink reference signal, embodiments of this application provide an uplink reference signal association method and communication device. The uplink reference signal association method and communication device provided in these embodiments are further described in detail below:

[0152] Please see Figure 4 , Figure 4 This is a flowchart illustrating an uplink reference signal association method provided in an embodiment of this application. For example... Figure 4 As shown, the association method of the uplink reference signal includes the following steps 401 to 403. Figure 4 The subject of the method shown can be a terminal device, a first network device, or a chip in the terminal device or a chip in the first network device. Figure 4 The method will be explained using terminal devices and the first network device as examples. Specifically:

[0153] 401. The first network device generates first configuration information, which indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0154] The first network device can be a serving network device for the terminal device, for example, the first network device is a serving base station for the terminal device.

[0155] For example, the first configuration information may indicate that the uplink reference signals transmitted simultaneously on carrier 1 and carrier 2 of the terminal device are associated, and that the uplink reference signals transmitted simultaneously on carrier 3 and carrier 4 of the terminal device are associated.

[0156] For example, the first configuration information may indicate that the uplink reference signals simultaneously transmitted on BWP1 of carrier 1 and BWP3 of carrier 2 of the terminal device are related, and that the uplink reference signals simultaneously transmitted on BWP2 of carrier 1 and BWP4 of carrier 2 of the terminal device are related.

[0157] For example, the first configuration information can indicate that the uplink reference signals simultaneously transmitted on SRS resource set 11 and SRS resource set 31 of the terminal device are correlated. SRS resource set 11 is the SRS resource set in BWP1 of carrier 1. SRS resource set 31 is the SRS resource set in BWP3 of carrier 2.

[0158] In this context, simultaneously transmitted uplink reference signals can be understood as uplink reference signals with the same symbol. Alternatively, simultaneously transmitted uplink reference signals can be understood as uplink reference signals with different symbols, but transmitted simultaneously due to different timing.

[0159] In one possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers. That is, the first configuration information can indicate the association between uplink reference signals transmitted simultaneously on different carriers by indicating the association between these resources, thus accurately indicating the association between them. For example, if the first configuration information indicates that uplink reference signal resource 1 and uplink reference signal resource 2 transmitted simultaneously on different carriers are associated, then the first configuration information is equivalent to indicating that the uplink reference signal corresponding to uplink reference signal resource 1 and the uplink reference signal corresponding to uplink reference signal resource 2 are associated.

[0160] Optionally, the first configuration information includes configuration information for multiple carriers. The carrier configuration information includes the carrier's index and the configuration information for the bandwidth portion (BWP) within that carrier. The BWP configuration information includes the BWP's index and the configuration information for the uplink reference signal resource set within that BWP. The uplink reference signal resource set configuration information includes the uplink reference signal resource set's index and the configuration information for the uplink reference signal resources within that uplink reference signal resource set. In other words, the first configuration information can also indicate which BWPs the terminal device has on which carriers, which uplink reference signal resource sets it has under these BWPs, and which uplink reference signal resources it has on these uplink reference signal resource sets.

[0161] For example, such as Figure 5 As shown, the terminal device has three carriers, designated as carrier 1 to carrier 3. The first configuration information includes the configuration information for carrier 1 to carrier 3. Taking the configuration information for carrier 1 as an example, the configuration information for carrier 1 includes the index of carrier 1. Since carrier 1 includes BWP1 and BWP2, the configuration information for carrier 1 also includes the configuration information for BWP1 and BWP2. Optionally, the configuration information for carrier 1 may also include other attribute information of carrier 1.

[0162] The following explanation uses BWP1's configuration information as an example. Figure 5 As shown, the configuration information of BWP1 includes the index of BWP1. Since BWP1 includes SRS resource set 11 and SRS resource set 12, the configuration information of BWP1 also includes the configuration information of SRS resource set 11 and SRS resource set 12.

[0163] The configuration information for SRS resource set 11 includes an index for SRS resource set 11. Since SRS resource set 11 includes SRS resource 111 and SRS resource 112, its configuration information also includes configuration information for both SRS resource 111 and SRS resource 112. Specifically, the configuration information for SRS resource 111 includes its index, and the configuration information for SRS resource 112 includes its index.

[0164] Similarly, the configuration information of SRS resource set 12 includes the index of SRS resource set 12, the configuration information of SRS resource 121, and the configuration information of SRS resource 122. Specifically, the configuration information of SRS resource 121 includes its index, and the configuration information of SRS resource 122 includes its index.

[0165] In other words, the first configuration information indicates that the terminal device includes BWP1 and BWP2 on carrier 1. BWP1 includes SRS resource set 11 and SRS resource set 12. SRS resource set 11 includes SRS resource 111 and SRS resource 112. SRS resource set 12 includes SRS resource 121 and SRS resource 122. BWP2 includes SRS resource set 21 and SRS resource set 22. SRS resource set 21 includes SRS resource 211 and SRS resource 212. SRS resource set 22 includes SRS resource 221 and SRS resource 222. The same logic applies to other carriers, and will not be elaborated here.

[0166] The first configuration information indicating the correlation between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following three ways:

[0167] ① The configuration information of the first uplink reference signal resource set also includes at least one first index information. This first index information includes an index of the second carrier, an index of the second BWP within the second carrier, and an index of the second uplink reference signal resource set within the second BWP. This indicates that the uplink reference signal resources simultaneously transmitted from the first uplink reference signal resource set and at least one second uplink reference signal resource set are associated. The first uplink reference signal resource set and the at least one second uplink reference signal resource set are resource sets on different carriers configured by the first configuration information. Method ① is equivalent to indicating the association between uplink reference signal resource sets transmitted simultaneously on different carriers by indicating the association between them, which helps save signaling overhead.

[0168] Optionally, if the uplink reference signal resource is an SRS resource, the configuration information for the first uplink reference signal resource set can be either SRS-ResourceSet or SRS-PosResourceSet.

[0169] For example, the cell structure of the configuration information of the first uplink reference signal resource set can be as follows:

[0170]

[0171]

[0172] In the above cell structure, the underlined portion of SRS-ResourceSetID-Info-r17 represents the first index information. The underlined portion of servingCellId-r17 represents the index of the second carrier. The underlined portion of uplinkBWP-r17 represents the index of the second BWP. The underlined portion of srs-ResourceSetId-r17 represents the index of the second uplink reference signal resource set. It can be seen from the above cell structure that the configuration information of the first uplink reference signal resource set may include one or more first index information entries.

[0173] For example, such as Figure 6 As shown, assuming the configuration information of SRS resource set 11 under carrier 1 includes {the index of carrier 2, the index of BWP3 under carrier 2, and the index of SRS resource set 31 under BWP3} and {the index of carrier 3, the index of BWP5 under carrier 3, and the index of SRS resource set 51 under BWP5}, then the first configuration information indicates that the SRS resources transmitted simultaneously in SRS resource set 11, SRS resource set 31, and SRS resource set 51 are associated.

[0174] Optionally, if the indices of the uplink reference signal resource sets in each carrier are different, the configuration information of the first uplink reference signal resource set may include only the index of at least one second uplink reference signal resource set, without needing to include the index of the second carrier and the index of the second BWP.

[0175] Optionally, the association between the first uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one second uplink reference signal resource set can be indicated without using the method described above①. For example, the indexes of the first uplink reference signal resource set and at least one second uplink reference signal resource set can be configured to be the same to indicate that the first uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one second uplink reference signal resource set are associated.

[0176] ② The configuration information of the first BWP also includes at least one second index, which includes an index of the second carrier and an index of the second BWP within the second carrier. This indicates that the uplink reference signal resources transmitted simultaneously in the first BWP and at least one second BWP are associated. The first BWP and the second BWP are BWPs on different carriers configured by the first configuration information. Method ② is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between BWPs on different carriers, which helps to save signaling overhead.

[0177] Optionally, if the uplink reference signal resource is an SRS resource, the configuration information of the first BWP includes an SRS configuration (SRS-Config). Specifically, the SRS configuration in the configuration information of the first BWP may include at least one second index information. Alternatively, the configuration information of the first BWP may include at least one second index information in a location other than the SRS configuration. SRS-ResourceSet or SRS-PosResourceSet is within the SRS configuration.

[0178] For example, the cell structure configured in SRS can be as follows:

[0179]

[0180]

[0181] In the above information cell structure, the underlined portion of AssociatedSRS-Info-r17 represents the second index information. The underlined portion of servingCellId-r17 represents the index of the second carrier. The underlined portion of uplinkBWP-r17 represents the index of the second BWP. It can be seen from the above information cell structure that the configuration information of the first BWP may include one or more second index information.

[0182] For example, such as Figure 7 As shown, assuming the configuration information of BWP1 under carrier 1 includes {the index of carrier 2, the index of BWP3 under carrier 2} and {the index of carrier 3, the index of BWP5 under carrier 3}, then the first configuration information indicates that the SRS resources transmitted simultaneously in BWP1, BWP3, and BWP5 are related.

[0183] Optionally, if the BWP indexes in each carrier are different, the configuration information of the first BWP may include only the index of at least one second BWP, without including the index of the second carrier.

[0184] Optionally, the association between the index of the first BWP and the uplink reference signal resource simultaneously transmitted in at least one second BWP can be indicated without using the method described in ② above. For example, the index of the first BWP can be configured to be the same as the index of at least one BWP to indicate that the first BWP is associated with the uplink reference signal resource simultaneously transmitted in the at least one second BWP.

[0185] ③ The configuration information of the first carrier also includes an index of at least one second carrier to indicate that the uplink reference signal resources transmitted simultaneously on the first carrier and at least one second carrier are associated. The first carrier and the second carrier are different carriers configured in the first configuration information. Method ③ is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between different carriers, which helps to save signaling overhead.

[0186] Optionally, the configuration information for the first carrier can be ServingCellConfig.

[0187] For example, the cell structure of the configuration information for the first carrier can be as follows:

[0188]

[0189]

[0190]

[0191] In the underlined portion above, servingCellId-r17 in SRS-AssociatedCell-Info-r17 represents the index of the second BWP.

[0192] For example, such as Figure 8 As shown, assuming the configuration information of carrier 1 includes the indexes of carrier 2 and carrier 3, then the first configuration information indicates that the uplink reference signal resources transmitted simultaneously in carriers 1, 2, and 3 are related.

[0193] Optionally, in methods ① to ③ above, the index of the second carrier includes one or more of the following: the index of the serving cell where the second carrier is located, and indication information indicating whether the second carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell. For example, if the serving cell where the second carrier is located includes only one uplink carrier, the index of the second carrier can be represented by the index of the serving cell where the second carrier is located. If the serving cell where the second carrier is located includes two uplink carriers, the index of the second carrier can be represented by the index of the serving cell where the second carrier is located plus indication information indicating whether the second carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell. Based on this optional method, it is beneficial to accurately indicate the second carrier.

[0194] In another possible implementation, the first configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the first configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, and will not be repeated here. For example, if the first configuration information indicates that a first uplink reference signal resource set is associated with at least one second uplink reference signal resource set, then there is an association between the first uplink reference signal resource set and the uplink reference signals transmitted simultaneously in at least one second uplink reference signal resource set.

[0195] In another possible implementation, the first configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the correlation between BWPs on different carriers. The specific implementation of the first configuration information indicating the correlation between BWPs on different carriers can be found in the description of method ② above, and will not be repeated here. For example, if the first configuration information indicates that the first BWP is correlated with at least one second BWP, then there is a correlation between the first BWP and the uplink reference signals transmitted simultaneously in at least one second BWP.

[0196] In another possible implementation, the first configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the first configuration information indicates the correlation between different carriers. The specific implementation of the first configuration information indicating the correlation between different carriers can be found in the description of method ③ above, and will not be repeated here. For example, if the first configuration information indicates that the first carrier is correlated with at least one second carrier, then there is a correlation between the first carrier and the uplink reference signals transmitted simultaneously on at least one second carrier.

[0197] 402. The first network device sends the first configuration information to the terminal device.

[0198] In this embodiment of the application, after the first network device generates the first configuration information, it sends the first configuration information to the terminal device.

[0199] 403. The terminal device sends an uplink reference signal with a correlation; the uplink reference signals with a correlation share an antenna port or have a phase difference.

[0200] In this embodiment of the application, after receiving the first configuration information, the terminal device sends an uplink reference signal with an association relationship.

[0201] In this context, an antenna port is defined as an antenna port whose channel on one symbol can be inferred from the signal carried by that same antenna port on another symbol. In other words, if the channel carried by one antenna port on one symbol can be inferred from the channel carried by another antenna port on another symbol, then these two antenna ports are considered the same antenna port. In this embodiment, a shared antenna port for related uplink reference signals refers to the antenna ports of related uplink reference signals being the same antenna port. A shared antenna port for related uplink reference signals can also be understood as: related uplink reference signals having the same channel, or related uplink reference signals having continuous phase, or related uplink reference signals having the same phase.

[0202] When a terminal device transmits correlated uplink reference signals, it either makes the correlated uplink reference signals share an antenna port or makes them have a phase difference. For example, suppose SRS 111, SRS 311, and SRS 511 transmitted simultaneously on different carriers are correlated. If the correlated SRSs share an antenna port, SRS 111, SRS 311, and SRS 511 will experience the exact same channel, and the second network device will simultaneously measure the channel experienced by SRS 111, SRS 311, and SRS 511. This can be equivalently viewed as the terminal device transmitting a new SRS with a bandwidth equivalent to the sum of SRS 111, SRS 311, and SRS 511, and the second network device also receives this new SRS, effectively expanding the signal bandwidth. Since positioning accuracy largely depends on signal bandwidth, this can improve positioning accuracy.

[0203] For example, suppose SRS 111, SRS 311, and SRS 511, transmitted simultaneously on different carriers, are correlated. If the correlated SRSs have a phase difference—meaning that the channels experienced by SRS 111, SRS 311, and SRS 511 are identical except for this phase difference—the second network device can estimate this phase difference and then compensate for the channel phase of some of the SRSs 111, SRS 311, and SRS 511 using this phase difference. This allows the channels of SRS 111, SRS 311, and SRS 511 to have the same phase, thus enabling them to share an antenna port. Based on the previous analysis, sharing an antenna port with SRS 111, SRS 311, and SRS 511 effectively expands the signal bandwidth. Since positioning accuracy largely depends on signal bandwidth, this can improve positioning accuracy. On the other hand, even if the second network device cannot estimate the phase difference and does not compensate for the phase difference, the second network device can still combine the measurement results on the respective channels of SRS 111, SRS311, and SRS 511 to obtain frequency diversity gain and improve positioning accuracy, but it cannot obtain an equivalent large bandwidth gain.

[0204] It can be seen that, based on Figure 4 The described method allows the network side to configure the terminal device to share an antenna port among uplink reference signals or to have a phase difference between them. Sharing an antenna port among multiple uplink reference signals means that these signals experience the same channel, which can be equivalently viewed as the terminal device transmitting a new uplink reference signal whose bandwidth is equivalent to the sum of the bandwidths of the multiple uplink reference signals. Therefore, sharing an antenna port among multiple uplink reference signals can expand the signal bandwidth. Thus, by configuring the terminal device to share an antenna port among uplink reference signals, a large-bandwidth uplink reference signal configuration can be achieved. By configuring the terminal device to have a phase difference between uplink reference signals, the network device can estimate this phase difference and then compensate for the channel phase of the uplink reference signals using this phase difference, thereby enabling the sharing of an antenna port among multiple uplink reference signals to expand the signal bandwidth. Therefore, by configuring the terminal device to have a phase difference between uplink reference signals, a large-bandwidth uplink reference signal configuration can also be achieved.

[0205] In one possible implementation, during the transmission of correlated uplink reference signals by the terminal device, the phase difference between the correlated uplink reference signals is a fixed value. Optionally, the small change in the phase difference between the correlated uplink reference signals during transmission can also be understood as the phase difference being a fixed value. By keeping the phase difference between the correlated uplink reference signals a fixed value during transmission, the terminal device can more accurately estimate the phase difference between them. For example, suppose SRS 111, SRS 311, and SRS 511, transmitted simultaneously on different carriers, are correlated. During the transmission of related SRS by the terminal device, the phase difference between SRS 111 and SRS 311 is a fixed value 1, the phase difference between SRS 111 and SRS 511 is a fixed value 2, and the phase difference between SRS 311 and SRS 511 is a fixed value 3. Fixed values ​​1, 2, and 3 can be the same or different.

[0206] In one possible implementation, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to the same antenna port. That is, when the uplink reference signal has multiple antenna ports, the same antenna port number of related uplink reference signals corresponds to a shared antenna port. For example, assume that SRS 111, SRS 311, and SRS 511, transmitted simultaneously on different carriers, are related. SRS 111 has two antenna ports, numbered antenna port #1 and antenna port #2; SRS 311 has two antenna ports, numbered antenna port #1 and antenna port #2; and SRS 511 has two antenna ports, numbered antenna port #1 and antenna port #2. Antenna port #1 of SRS 111, antenna port #1 of SRS 311, and antenna port #1 of SRS 511 correspond to the same antenna port. Antenna port #2 of SRS 111, antenna port #2 of SRS 311, and antenna port #2 of SRS 511 all correspond to the same antenna port.

[0207] In one possible implementation, the first configuration information further indicates that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference. For example, the protocol may specify two association types: associated uplink reference signals sharing an antenna port and associated uplink reference signals having a phase difference. The first network device can select one of these two association types as needed and indicate the selected association type to the terminal device through the first configuration information. After receiving the first configuration information, the terminal device transmits the associated uplink reference signal based on the association type indicated by the first configuration information. Based on this possible implementation, the network side can flexibly configure the association type to the terminal device.

[0208] Optionally, the type of association may not be indicated through the first configuration information; the protocol may directly specify a certain association type. For example, the protocol may directly specify that uplink reference signals with an association share an antenna port, or the protocol may directly specify that uplink reference signals with an association have a phase difference.

[0209] Please see Figure 9 , Figure 9 This is a flowchart illustrating an uplink reference signal association method provided in an embodiment of this application. For example... Figure 9 As shown, the association method of the uplink reference signal includes the following steps 901 to 907. Figure 9 The subject of the method shown can be a terminal device, a first network device, a second network device, and a location management device, or the subject can be a chip in the terminal device, a chip in the first network device, a chip in the second network device, and a chip in the location management device. Figure 9 The method will be illustrated using a terminal device, a first network device, a second network device, and a positioning management device as the implementing entities. Specifically:

[0210] 901. The first network device generates first configuration information, which indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0211] 902. The first network device sends the first configuration information to the terminal device.

[0212] The specific implementation methods of steps 901 and 902 can be found in the specific implementation methods of steps 401 and 402 above, and will not be repeated here.

[0213] 903. The first network device generates second configuration information, which indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0214] Steps 903 and 904 can be executed before or after steps 901 and 902, or steps 903 and 904 can be executed simultaneously with steps 901 and 902.

[0215] The association relationship indicated by the second configuration information may be the same as or different from the association relationship indicated by the first configuration information. For example, the first configuration information indicates that the SRS sent simultaneously in SRS resource set 11, SRS resource set 31, and SRS resource set 51 are associated. The second configuration information also indicates that the SRS sent simultaneously in SRS resource set 11, SRS resource set 31, and SRS resource set 51 are associated.

[0216] For example, the first configuration information indicates that the SRS transmitted simultaneously in BWP1, BWP3, and BWP5 are associated. The second configuration information indicates that the SRS transmitted simultaneously in SRS resource set 11, SRS resource set 31, and SRS resource set 51 are associated. Alternatively, the second configuration information indicates that the SRS transmitted simultaneously in carrier 1, carrier 2, and carrier 3 are associated. Carrier 1 includes BWP1, and BWP1 includes SRS resource set 11. Carrier 2 includes BWP3, and BWP3 includes SRS resource set 31. Carrier 3 includes BWP5, and BWP5 includes SRS resource set 51.

[0217] For example, the first configuration information indicates that the SRS transmitted simultaneously on carriers 1, 2, and 3 are associated. The second configuration information indicates that the SRS transmitted simultaneously on carriers 1, 2, and 3 are associated.

[0218] In one possible implementation, the second configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the association between uplink reference signal resources transmitted simultaneously on different carriers. That is, the second configuration information can indicate the association between uplink reference signals transmitted simultaneously on different carriers by indicating the association between these resources, thus accurately indicating the association between them. For example, if the second configuration information indicates that uplink reference signal resource 1 and uplink reference signal resource 2 transmitted simultaneously on different carriers are associated, then the second configuration information is equivalent to indicating that the uplink reference signal corresponding to uplink reference signal resource 1 and the uplink reference signal corresponding to uplink reference signal resource 2 are associated.

[0219] Optionally, the second configuration information includes configuration information for multiple carriers. This carrier configuration information includes the carrier's index and the configuration information for the uplink reference signal resource set within that carrier. The configuration information for the uplink reference signal resource set includes the uplink reference signal resource set's index and the configuration information for the uplink reference signal resources within that set. In other words, the second configuration information can also indicate which uplink reference signal resource sets the terminal device has on which carriers, and which uplink reference signal resources it has on those uplink reference signal resource sets. The uplink reference signal resource set indicated in the second configuration information can be the uplink reference signal resource set on an active BWP (Browser Window) within a carrier. One uplink reference signal resource set can be active on a single carrier simultaneously.

[0220] For example, the first configuration information is as follows Figure 6 As shown. BWP1 is active on carrier 1, BWP3 is active on carrier 2, and BWP5 is active on carrier 3. Figure 10 As shown, the second configuration information includes the configuration information for carrier 1 to carrier 3. The configuration information for carrier 1 includes the carrier 1 index, the configuration information for SRS resource set 11, and the configuration information for SRS resource set 12. The configuration information for carrier 2 includes the carrier 2 index, the configuration information for SRS resource set 31, and the configuration information for SRS resource set 32. The configuration information for carrier 3 includes the carrier 3 index, the configuration information for SRS resource set 51, and the configuration information for SRS resource set 52.

[0221] In other words, the second configuration information indicates that the terminal device includes SRS resource set 11 and SRS resource set 12 on carrier 1. SRS resource set 11 includes SRS resource 111 and SRS resource 112. SRS resource set 12 includes SRS resource 121 and SRS resource 122. It also indicates that the terminal device includes SRS resource set 31 and SRS resource set 32 ​​on carrier 2. SRS resource set 31 includes SRS resource 311 and SRS resource 312. SRS resource set 32 ​​includes SRS resource 321 and SRS resource 322. Furthermore, it indicates that the terminal device includes SRS resource set 51 and SRS resource set 52 on carrier 3. SRS resource set 51 includes SRS resource 511 and SRS resource 512. SRS resource set 52 includes SRS resource 521 and SRS resource 522.

[0222] The second configuration information indicating the correlation between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following two specific ways:

[0223] ① The configuration information of the third uplink reference signal resource set also includes at least one third index information. This third index information includes the index of the fourth carrier and the index of the fourth uplink reference signal resource set in the fourth carrier, indicating that the third uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one fourth uplink reference signal resource set are associated. The third uplink reference signal resource set and the at least one fourth uplink reference signal resource set are resource sets on different carriers configured by the second configuration information. Method ① is equivalent to indicating the association between uplink reference signal resource sets transmitted on different carriers by indicating the association between them, which helps to save signaling overhead.

[0224] The principle of the second configuration information indicating the association relationship ① is the same as that of the first configuration information indicating the association relationship ①, and will not be elaborated here.

[0225] Optionally, if the indices of the uplink reference signal resource sets in each carrier are different, the configuration information of the third uplink reference signal resource set may include only the index of at least one fourth uplink reference signal resource set, without needing to include the index of the fourth carrier.

[0226] Optionally, the association relationship between the third uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one fourth uplink reference signal resource set can be indicated without using the second configuration information indicated in method ① above. For example, the indexes of the third uplink reference signal resource set and at least one fourth uplink reference signal resource set can be configured to be the same to indicate that the third uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one fourth uplink reference signal resource set are associated.

[0227] ② The configuration information of the third carrier also includes an index of at least one fourth carrier to indicate that the third carrier and the uplink reference signal resources transmitted simultaneously on the at least one fourth carrier are associated. The third carrier and the at least one fourth carrier are different carriers configured in the second configuration information. Method ② is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between different carriers, which helps to save signaling overhead.

[0228] The principle of the second configuration information indicating the association relationship ② is the same as that of the first configuration information indicating the association relationship ③, and will not be elaborated here.

[0229] Optionally, in methods ① and ② of indicating association relationships in the second configuration information, the index of the fourth carrier includes one or more of the following: the index of the serving cell where the fourth carrier is located, and indication information indicating whether the fourth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell. For example, if the serving cell includes only one uplink carrier, the index of the second carrier can be represented by the index of the serving cell where the fourth carrier is located. If the serving cell includes two uplink carriers, the index of the second carrier can be represented by the index of the serving cell where the fourth carrier is located plus indication information indicating whether the fourth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0230] In another possible implementation, the second configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the second configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① of the second configuration information indicating association, and will not be repeated here. For example, if the second configuration information indicates that a third uplink reference signal resource set is associated with a fourth uplink reference signal resource set, then the third uplink reference signal resource set and the uplink reference signals transmitted simultaneously in the fourth uplink reference signal resource set are associated.

[0231] In another possible implementation, the second configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the second configuration information indicates the correlation between different carriers. The specific implementation of the second configuration information indicating the correlation between different carriers can be found in the description of method ② above, and will not be repeated here. For example, if the second configuration information indicates that a third carrier is correlated with indicating a fourth carrier, then the third carrier is correlated with the uplink reference signals transmitted simultaneously on the fourth carrier.

[0232] 904. The first network device sends the second configuration information to the positioning management device.

[0233] In this embodiment of the application, after the first network device generates the second configuration information, it sends the second configuration information to the positioning management device.

[0234] 905. The positioning management device sends third configuration information to the second network device, which also indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0235] In this embodiment of the application, after receiving the second configuration information sent by the first network device, the positioning management device sends the third configuration information to the second network device.

[0236] The third configuration information can be generated based on the second configuration information. The third configuration information may include all or part of the content of the second configuration information.

[0237] For example, the first configuration information indicates that SRSs sent simultaneously in SRS resource sets 11, 31, and 51 are associated. The second configuration information also indicates that SRSs sent simultaneously in SRS resource sets 11, 31, and 51 are associated. The third configuration information also indicates that SRSs sent simultaneously in SRS resource sets 11, 31, and 51 are associated. Alternatively, the third configuration information indicates that SRSs sent simultaneously in SRS resource sets 11 and 31 are associated.

[0238] For example, the first configuration information indicates that the SRS transmitted simultaneously on carriers 1, 2, and 3 are associated. The second configuration information indicates that the SRS transmitted simultaneously on carriers 1, 2, and 3 are associated. The third configuration information also indicates that the SRS transmitted simultaneously on carriers 1, 2, and 3 are associated. Alternatively, the third configuration information indicates that the SRS transmitted simultaneously on carriers 1 and 2 are associated.

[0239] In one possible implementation, the third configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the correlation between uplink reference signal resources transmitted simultaneously on different carriers. That is, the third configuration information can indicate the correlation between uplink reference signals transmitted simultaneously on different carriers by indicating the correlation between these resources, thus accurately indicating the correlation between them. For example, if the third configuration information indicates that uplink reference signal resource 1 and uplink reference signal resource 2 transmitted simultaneously on different carriers are correlated, then the third configuration information is equivalent to indicating that the uplink reference signal corresponding to uplink reference signal resource 1 and the uplink reference signal corresponding to uplink reference signal resource 2 are correlated.

[0240] Optionally, the third configuration information includes configuration information for multiple carriers. The carrier configuration information includes the index of the carrier and the configuration information of the uplink reference signal resource set within that carrier. The uplink reference signal resource set configuration information includes the index of the uplink reference signal resource set and the configuration information of the uplink reference signal resources within that set. In other words, the third configuration information can also indicate which uplink reference signal resource sets the terminal device has on which carriers, and which uplink reference signal resources it has on those uplink reference signal resource sets. The uplink reference signal resource set indicated in the third configuration information can be the uplink reference signal resource set on an active BWP (Browser Protected Device) within a carrier.

[0241] The third configuration information indicating the correlation between uplink reference signal resources transmitted simultaneously on different carriers can be implemented in the following two ways:

[0242] ① The configuration information of the fifth uplink reference signal resource set also includes at least one fourth index information. This fourth index information includes the index of the sixth carrier and the index of the sixth uplink reference signal resource set within the sixth carrier. This indicates that the uplink reference signal resources transmitted simultaneously in the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are associated. The fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set are resource sets configured on different carriers by the third configuration information. Method ① is equivalent to indicating the association between uplink reference signal resource sets transmitted simultaneously on different carriers by indicating the association between them, which helps save signaling overhead.

[0243] The principle of the third configuration information indicating the association relationship ① is the same as that of the first configuration information indicating the association relationship ①, and will not be elaborated here.

[0244] Optionally, if the indices of the uplink reference signal resource sets in each carrier are different, the configuration information of the fifth uplink reference signal resource set may include only the index of at least one sixth uplink reference signal resource set, without needing to include the index of the sixth carrier.

[0245] Optionally, the association between the fifth uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one sixth uplink reference signal resource set can be indicated without using the method described above ①. For example, the indexes of the fifth uplink reference signal resource set and at least one sixth uplink reference signal resource set can be configured to be the same to indicate that the fifth uplink reference signal resource set and the uplink reference signal resources simultaneously transmitted in at least one sixth uplink reference signal resource set are associated.

[0246] ② The configuration information of the fifth carrier also includes an index of at least one sixth carrier to indicate that the uplink reference signal resources transmitted simultaneously on the fifth carrier and at least one sixth carrier are associated. The fifth carrier and the at least one sixth carrier are different carriers configured in the third configuration information. Method ② is equivalent to indicating the association between uplink reference signal resources transmitted simultaneously on different carriers by indicating the association between different carriers, which helps to save signaling overhead.

[0247] The principle of method ②, which indicates the association relationship in the third configuration information, is the same as that of method ③, which indicates the association relationship in the first configuration information, and will not be elaborated here.

[0248] Optionally, in methods ① and ② of indicating the association relationship in the third configuration information, the index of the sixth carrier includes one or more of the following: the index of the serving cell where the sixth carrier is located, and indication information indicating whether the sixth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell. For example, if the serving cell includes only one uplink carrier, the index of the second carrier can be represented by the index of the serving cell where the sixth carrier is located. If the serving cell includes two uplink carriers, the index of the second carrier can be represented by the index of the serving cell where the sixth carrier is located plus indication information indicating whether the sixth carrier is a regular uplink carrier or an auxiliary uplink carrier of the serving cell.

[0249] In another possible implementation, the third configuration information indicates the association between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the association between uplink reference signal resource sets on different carriers. The specific implementation of the third configuration information indicating the association between uplink reference signal resource sets on different carriers can be found in the description of method ① above, and will not be repeated here. For example, if the third configuration information indicates that a fifth uplink reference signal resource set is associated with a sixth uplink reference signal resource set, then the fifth uplink reference signal resource set and the uplink reference signals transmitted simultaneously in the sixth uplink reference signal resource set are associated.

[0250] In another possible implementation, the third configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers in the following way: the third configuration information indicates the correlation between different carriers. The specific implementation of the third configuration information indicating the correlation between different carriers can be found in the description of method ② above, and will not be repeated here. For example, if the third configuration information indicates that the fifth carrier is correlated with indicating a sixth carrier, then the fifth carrier is correlated with the uplink reference signals transmitted simultaneously on the sixth carrier.

[0251] In one possible implementation, the first, second, and third configuration information are further used to indicate whether the associated uplink reference signals share an antenna port or whether the associated uplink reference signals have a phase difference. For example, the protocol may specify two association types: associated uplink reference signals sharing an antenna port and associated uplink reference signals having a phase difference. The first network device can select one of these two association types as needed and indicate the selected association type to the terminal device through the first configuration information. After receiving the first configuration information, the terminal device transmits the associated uplink reference signal based on the association type indicated by the first configuration information. After receiving the third configuration information, the second network device measures the associated uplink reference signal based on the association type indicated by the third configuration information. Based on this possible implementation, the network side can flexibly configure the association type to the terminal device.

[0252] Optionally, instead of indicating the type of association through the first, second, and third configuration information, the protocol can directly specify a certain association type. For example, the protocol can directly specify that uplink reference signals with an association share an antenna port, or the protocol can directly specify that uplink reference signals with an association have a phase difference.

[0253] 906. The terminal equipment sends uplink reference signals with a correlation; the uplink reference signals with a correlation share an antenna port or have a phase difference.

[0254] The specific implementation of step 906 can be found in the specific implementation of step 403, and will not be repeated here.

[0255] 907. The second network device measures the uplink reference signals that are related.

[0256] In this embodiment, after receiving the third configuration information, the second network device measures the related uplink reference signals configured in the third configuration information. The second network device can perform joint measurements on the related uplink reference signals configured in the third configuration information.

[0257] Optionally, the second network device may specifically perform joint measurements of correlated uplink reference signals via TRP or RP.

[0258] It can be seen that, based on Figure 9 The described method enables the configuration of a large-bandwidth uplink reference signal.

[0259] Please see Figure 11 , Figure 11 This is a flowchart illustrating an uplink reference signal association method provided in an embodiment of this application. For example... Figure 11 As shown, the association method of the uplink reference signal includes the following steps 1101 to 1110. Figure 11 The subject of the method shown can be a terminal device, a first network device, a second network device, and a location management device, or the subject can be a chip in the terminal device, a chip in the first network device, a chip in the second network device, and a chip in the location management device. Figure 11 The method will be illustrated using a terminal device, a first network device, a second network device, and a positioning management device as the implementing entities. Specifically:

[0260] 1101. The terminal device reports capability information to the first network device. This capability information is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously via a common antenna port, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference.

[0261] Step 1101 can be executed before step 1102, after step 1102, or simultaneously with step 1102.

[0262] By reporting the terminal device's capability information to the first network device, the first network device can accurately determine how to configure the uplink reference signal for the terminal device based on the terminal device's capability information. Alternatively, the first network device can perform other operations based on the terminal device's capability information.

[0263] In one possible implementation, the reporting granularity of capability information is per frequency band, per frequency band group, per frequency band within a frequency band group, or per frequency band subset within a frequency band group. Based on this possible implementation, the capability information of terminal devices can be reported at a relatively fine granularity.

[0264] ① Per-band reporting. The terminal device reports capability information for each frequency band. A frequency band may include one or more carriers.

[0265] For example, the terminal device includes frequency band 1 and frequency band 2. The terminal device first reports the capability information corresponding to frequency band 1, and then reports the capability information corresponding to frequency band 2. The capability information corresponding to frequency band 1 is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously on a common antenna port under frequency band 1, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference under frequency band 1.

[0266] The capability information corresponding to frequency band 2 is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously on the same antenna port under frequency band 2, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference under frequency band 2.

[0267] ② Per-band reporting. A frequency band group can include one or more frequency bands. Assume the terminal device has three frequency band groups: band group 1, band group 2, and band group 3. Band group 1 includes band 1, band group 2 includes band 2, and band group 3 includes both band 1 and band 2. The terminal device first reports the capability information corresponding to band group 1, then reports the capability information corresponding to band group 2, and finally reports the capability information corresponding to band group 3.

[0268] The capability information corresponding to band group 1 is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously under band group 1 and share an antenna port, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously under band group 1 and have a phase difference.

[0269] The capability information corresponding to band group 2 is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously under band group 2 with a common antenna port, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference under band group 2.

[0270] The capability information corresponding to band group 3 is used to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a common antenna port under band group 3, or to indicate whether the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference under band group 3.

[0271] ③ Per-band reporting within a frequency band group. Assume the terminal device has three frequency band groups: Band Group 1, Band Group 2, and Band Group 3. Band Group 1 includes Band 1, Band Group 2 includes Band 2, and Band Group 3 includes both Band 1 and Band 2. The terminal device first reports the capability information corresponding to Band 1 within Band Group 1, then reports the capability information corresponding to Band 2 within Band Group 2, then reports the capability information corresponding to Band 1 within Band Group 3, and finally reports the capability information corresponding to Band 2 within Band Group 3.

[0272] ④ Reporting of frequency band subsets within each frequency band group. Assume the terminal device has three frequency band groups: band group 1, band group 2, and band group 3. Band group 1 includes band 1, band group 2 includes band 2, and band group 3 includes both band 1 and band 2. Band group 1 includes one frequency band subset, band 1. Band group 2 includes one frequency band subset, band 2. Band group 3 includes three frequency band subsets: band 1, band 2, and band 1 + band 2.

[0273] The terminal device first reports the capability information corresponding to frequency band 1 in frequency band group 1, then reports the capability information corresponding to frequency band 2 in frequency band group 2, then reports the capability information corresponding to frequency band 1 in frequency band group 3, then reports the capability information corresponding to frequency band 2 in frequency band group 3, and finally reports the capability information corresponding to both frequency band 1 and frequency band 2 in frequency band group 3.

[0274] In one possible implementation, the terminal device may also report the aforementioned capability information to the positioning management device. The granularity of capability information reporting can be per frequency band, per frequency band group, per frequency band within a frequency band group, or per subset of a frequency band group within a frequency band group. After receiving the capability information from the terminal device, the positioning management device can determine whether to request the generation of first configuration information from the first network device based on the terminal device's capability information.

[0275] In one possible implementation, the terminal device does not report capability information to the first network device. Instead, the terminal device reports capability information to the location management device, which then forwards the capability information to the first network device.

[0276] In another possible implementation, the terminal device may not report capability information to the first network device and the positioning management device. The first network device and the positioning management device may assume that the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a common antenna port, or may indicate that the terminal device supports multiple uplink reference signals to be transmitted simultaneously with a phase difference.

[0277] 1102. The positioning management device sends the first information to the first network device.

[0278] The first piece of information can be in the following two cases:

[0279] ① The first information is used to request the first network device to configure an uplink reference signal with a preset bandwidth, which is greater than 100 MHz or greater than 400 MHz.

[0280] In scenario ①, after receiving an uplink reference signal requesting the first network device to configure a preset bandwidth, the first network device generates first configuration information. This first configuration information indicates the correlation between uplink reference signals transmitted simultaneously on different carriers. That is, the positioning management device implicitly requests the first network device to configure the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0281] In one possible implementation, the first information is specifically used to request the first network device to configure an uplink reference signal with a preset bandwidth on a preset frequency point. When the preset frequency point belongs to frequency range 1, the preset bandwidth is greater than 100 MHz; when the preset frequency point belongs to frequency range 2, the preset bandwidth is greater than 400 MHz. Frequency range 1 can be below 7.1 GHz, and frequency range 2 can be from 24 GHz to 52.6 GHz.

[0282] ② This first information is used to request the first network device to configure the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0283] In scenario ②, the positioning management device can explicitly request the first network device to configure the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0284] In one possible implementation, the first information is further used to request that the associated uplink reference signals share an antenna port or that the associated uplink reference signals have a phase difference. Based on this possible implementation, the positioning management device can recommend the type of association that should be configured to the first network device based on the capability information of the network device used to measure the uplink reference signal, which helps the first network device to reasonably configure the type of association.

[0285] In one possible implementation, the location management device may also skip step 1102 and have the first network device actively generate the first configuration information.

[0286] 1103. The first network device generates first configuration information, which indicates the correlation between uplink reference signals transmitted simultaneously on different carriers; the uplink reference signals with correlation share an antenna port or have a phase difference.

[0287] In this embodiment of the application, the first network device can generate first configuration information after receiving the capability information of the terminal device and the first information sent by the positioning management device.

[0288] The first network device can generate first configuration information and second configuration information based on the capability information of the terminal device. For example, consider the terminal device reporting capability information band by band. Assume the terminal device includes band 1 and band 2. The terminal device first reports the capability information corresponding to band 1, and then reports the capability information corresponding to band 2. The capability information corresponding to band 1 indicates that the terminal device supports the simultaneous transmission of multiple uplink reference signals sharing an antenna port in band 1. The capability information corresponding to band 2 indicates that the terminal device does not support the simultaneous transmission of multiple uplink reference signals sharing an antenna port in band 2.

[0289] Frequency band 1 includes carrier 1 and carrier 2, and frequency band 2 includes carrier 3. The first configuration information can indicate the association between uplink reference signals simultaneously transmitted on carrier 1 and carrier 2. The second configuration information can indicate the association between uplink reference signals simultaneously transmitted on carrier 1 and carrier 2.

[0290] 1104. The first network device sends the first configuration information to the terminal device.

[0291] 1105. The first network device generates second configuration information, which indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0292] 1106. The first network device sends the second configuration information to the positioning management device.

[0293] 1107. The positioning management device sends third configuration information to the second network device. The third configuration information also indicates the correlation between uplink reference signals transmitted simultaneously on different carriers.

[0294] 1108. The terminal device sends an uplink reference signal with a correlation.

[0295] In one possible implementation, the terminal device transmits correlated uplink reference signals as follows: if the terminal device supports the simultaneous transmission of multiple uplink reference signals sharing an antenna port, or supports the simultaneous transmission of multiple uplink reference signals with a phase difference, then the terminal device transmits the correlated uplink reference signals, ensuring that the correlated uplink reference signals share an antenna port or have a phase difference. In other words, the terminal device first needs to determine whether its capabilities support the simultaneous transmission of multiple uplink reference signals sharing an antenna port, or supporting the simultaneous transmission of multiple uplink reference signals with a phase difference. If supported, it transmits correlated uplink reference signals, ensuring that the correlated uplink reference signals share an antenna port or have a phase difference. This possible implementation is beneficial for the terminal device to successfully transmit uplink reference signals.

[0296] For example, suppose the terminal device includes frequency band 1 and frequency band 2. The capability information corresponding to frequency band 1 indicates that the terminal device supports multiple uplink reference signals simultaneously transmitted on a shared antenna port in frequency band 1. The capability information corresponding to frequency band 2 indicates that the terminal device does not support multiple uplink reference signals simultaneously transmitted on a shared antenna port in frequency band 2. Frequency band 1 includes carrier 1 and carrier 2, and frequency band 2 includes carrier 3. The first configuration information indicates the association between the uplink reference signals simultaneously transmitted on carrier 1 and carrier 2. Since the terminal device supports multiple uplink reference signals simultaneously transmitted on a shared antenna port in frequency band 1, when the terminal device simultaneously transmits uplink reference signals on carrier 1 and carrier 2, the uplink reference signals simultaneously transmitted on carrier 1 and carrier 2 share the same antenna port.

[0297] 1109. The second network device measures the uplink reference signals that are correlated.

[0298] Other descriptions of steps 1105 to 1109 can be found in the descriptions of steps 903 to 907 above, and will not be repeated here. Optionally, in the entire embodiment of this application, the measurement of the uplink reference signal with correlation by the second network device can also be replaced by the second network device receiving the uplink reference signal with correlation.

[0299] 1110. The second network device sends measurement results to the positioning management device. The measurement results are obtained by the second network device from measuring the uplink reference signals with correlation. The measurement results include the index of the resource set where the uplink reference signals with correlation are located and / or the index of the carrier where the uplink reference signals with correlation are located.

[0300] In this embodiment of the application, after the second network device measures the uplink reference signal with the associated relationship configured by the third configuration information, it sends the measurement result to the positioning management device.

[0301] For example, suppose the measurement result is obtained from a joint measurement of SRS transmitted simultaneously in SRS resource set 11 and SRS resource set 31. SRS resource set 11 belongs to the SRS resource set under carrier 1, and SRS resource set 31 belongs to the SRS resource set under carrier 2. Then the measurement result can carry the index of SRS resource set 11 and the index of SRS resource set 31. Alternatively, it can carry {index of carrier 1, index of SRS resource set 11} and {index of carrier 2, index of SRS resource set 31}.

[0302] For example, suppose the measurement result is obtained by jointly measuring the SRS transmitted simultaneously on carrier 1 and carrier 2. Then the measurement result can carry the index of carrier 1 and the index of carrier 2.

[0303] By including the index of the resource set containing the associated uplink reference signal and / or the index of the carrier containing the associated uplink reference signal in the measurement results, the positioning management equipment can determine which uplink reference signal resources the measurement results were based on.

[0304] In another possible implementation, the terminal device may also omit the index of the resource set containing the associated uplink reference signal or the index of the carrier containing the associated uplink reference signal in the measurement results.
