Technical Field

[0001] This application relates to the field of wireless communication technology, such as a positioning sensing method, a communication node, and a storage medium. Background Technology

[0002] With the emergence of numerous new services and ever-expanding new demands, wireless communication networks not only need to significantly improve their communication efficiency but also expand the boundaries of their basic capabilities to support these innovative application scenarios. Traditionally, communication and sensing have been considered two separate technical fields: communication focuses on providing high-quality data transmission services, while sensing focuses on acquiring environmental information. However, this separate design often leads to problems such as resource waste, increased costs, and low energy efficiency. To overcome these limitations, Integrated Sensing and Communications (ISAC) technology has emerged. ISAC achieves multiple goals, including cost savings, reduced energy consumption, and resource optimization, by integrating communication and sensing functions into the same system. Under the ISAC architecture, base station transmission to user equipment (UE) and UE transmission to base station are two important sensing modes. Typically, the location of the base station is fixed, while the location of the UE may be mobile. Based on this, how to consider the transmission and reception between the base station and the UE and coordinate the realization of positioning and sensing has become an urgent problem to be solved.

[0040] The present application will now be described in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0041] Under the ISAC architecture, the network can perform communication and sensing tasks simultaneously. Sensing technology, based on mobile communication systems, monitors the environment and moving targets within it by transmitting wireless signals to a target area and analyzing the received signals.

[0042] Sensing technology encompasses two core modes: Mono-static Sensing, where signal transmission and reception are performed by the same device; and Bi-static Sensing, involving independent transmitting and receiving devices. Based on the roles played by different network elements (such as base stations or UEs), these modes can be further subdivided into six basic scenarios. Among them, base station transmitting and UE receiving, and UE transmitting and base station receiving, are two important sensing modes. Typically, the location of the base station is fixed, while the location of the UE may be mobile. The positioning and sensing fusion method provided in this application can achieve sensing of base station transmitting and UE receiving, or UE transmitting and base station receiving.

[0043] In radio access networks (RAN), the functionality of radio access points (RAN) is evolving towards modularity. The functions responsible for signal transmission and reception are termed Transmission Reception Points (TRPs), which are a crucial component of the RAN node. A RAN node comprises several TRPs, through which the RAN node executes specific radio transmission and reception operations. The RAN node makes decisions regarding radio resource management and scheduling, while the TRPs are responsible for translating these decisions into actual radio signal transmission and reception actions.

[0044] In future mobile communication networks, sensing and positioning functions will be simultaneously present. Positioning will facilitate applications such as autonomous driving; furthermore, sensing between the UE and RAN node will be achieved, and a key method involves calculating the location of the sensed target based on the UE's location and the TRP's location. Therefore, the simultaneous implementation of positioning and sensing functions in future mobile communication networks is an important direction of evolution.

[0045] Figure 1 This is a schematic diagram illustrating the fusion of positioning and sensing functions in one embodiment. Figure 1As shown, positioning and sensing can be achieved through a single function. This fused function can be called the sensing and positioning function, which can be implemented based on existing sensing or positioning functions, or it can be implemented based on a new function. This fused function is responsible for sensing and positioning service management and sensing and positioning data processing. The RAN node reports TRP information to the sensing and positioning function. Optionally, other modules may also exist in the RAN node, such as resource management, scheduling, data processing, and / or interface modules. The interface module is responsible for signaling interaction and data transmission between the RAN node and other functions.

[0046] Figure 2 This is a flowchart illustrating a location sensing method as provided in one embodiment, which can be applied to a radio access network node (such as a RAN node). Figure 2 As shown, the method provided in this embodiment includes steps 110 and 120.

[0047] In step 110, a positioning sensing request message of the positioning sensing function is received. The positioning sensing request message is used to request configuration information of the reference signal, and the reference signal includes at least one of the positioning reference signal and the sensing reference signal.

[0048] In step 120, a location sensing response message is sent to the location sensing function.

[0049] In this embodiment, the radio access network node can send positioning signals (also known as positioning reference signals) and sensing signals (also known as sensing reference signals) transmitted by one or more TRPs to the positioning and sensing function. The positioning and sensing function can send a positioning and sensing request message (also known as a TRP information request) to the RAN node to request the TRP to send configuration information for positioning signals and / or sensing signals; the radio access network node can send a positioning and sensing response message (also known as a TRP information response) to the positioning and sensing function to indicate that it has received the positioning and sensing request message from the positioning and sensing function.

[0050] In one embodiment, the location-aware request message includes at least one of the following:

[0051] Transmission Receiver Node List (TRP list) is used to indicate the node information of at least one transmission receiver node, wherein the node information of each TRP includes at least a TRP identifier (TRP ID), which is used to uniquely identify the TRP within the RAN node;

[0052] Request type, used to indicate the type of configuration information requested;

[0053] The Transmission Receiver Node Information Type List (i.e., the TRP Information Type List) is used to indicate the type of information requested by the Transmission Receiver Node and may include one or more information types.

[0054] Location and perception association indications are used to indicate the constraints for scheduling user equipment to participate in location and perception.

[0055] In one embodiment, the request type includes at least one of the following:

[0056] Location information indicator, used to indicate the location information of the requesting receiving node;

[0057] Sensing information indication, used to indicate the sensing information of the requesting receiving node;

[0058] Location and sensing information indication is used to indicate the sensing and location information of the requesting receiving node.

[0059] Optionally, the request type can be indicated by an enumerated list of types or by a bitmap.

[0060] In one embodiment, the list of transmission and reception node information types includes at least one of the following:

[0061] The location of the transmission receiving node (i.e., the TRP location);

[0062] Beam antenna information;

[0063] Positioning beam antenna information;

[0064] Sensing beam antenna information;

[0065] Downlink positioning reference signal configuration;

[0066] Uplink positioning reference signal configuration;

[0067] Downlink sensing reference signal configuration;

[0068] Uplink sensing reference signal configuration.

[0069] In one example, when the location-aware request message includes a location and awareness association indication, the radio access network node needs to meet the requirements of the location and awareness association indication when feeding back the downlink location reference signal configuration and / or downlink awareness signal configuration.

[0070] In one example, the list of transmit and receive node information types can be indicated by an enumerated list of types or by a bitmap.

[0071] In one example, when the same terminal participates in both localization and sensing, the terminal's location obtained through localization can be further used in sensing to determine the characteristics of the sensing target or environment. Therefore, there are constraints between obtaining the terminal's location through localization and obtaining the characteristics of the sensing target through sensing.

[0072] In one embodiment, the location and perception association indication includes at least one of the following:

[0073] The time difference between positioning and sensing measurements is a constraint used to indicate the time difference between positioning and sensing measurements.

[0074] The effective time for positioning measurement is used to indicate the effective time for completing the positioning measurement. The sensing measurement must be completed within the effective time of the positioning measurement. The sensing measurement needs to obtain the sensing result based on the information of the positioning measurement (such as the environment or the characteristics of objects in the environment). The position obtained by positioning measurement within the effective time of the positioning measurement is valid.

[0075] The effective time for sensing measurement is used to indicate the effective time for completing the sensing measurement. The positioning measurement must be completed within the effective time for sensing measurement, and the results obtained through sensing within the effective time for sensing measurement are valid.

[0076] Figure 3 This is a schematic diagram illustrating the constraint conditions for the measurement time difference between positioning measurement and sensing measurement, provided as an embodiment. Figure 3 As shown, the time difference between positioning measurement and sensing measurement can also be called the measurement time difference. It mainly refers to the time interval between adjacent sensing and positioning measurements. For example, the time interval between two adjacent downlink positioning and downlink sensing measurements in the downlink positioning reference signal configuration and downlink sensing reference signal configuration needs to meet the constraint that it does not exceed the measurement time difference. Here, adjacent sensing and positioning measurements refer to the features of the target further perceived based on the terminal position obtained from the positioning measurement.

[0077] Optionally, the location and perception association indicator can also be used to indicate constraints corresponding to at least one of the following sets of configurations:

[0078] Downlink positioning reference signal configuration and uplink sensing reference signal configuration;

[0079] Downlink sensing reference signal configuration and uplink positioning reference signal configuration;

[0080] Uplink sensing reference signal configuration and uplink positioning reference signal configuration.

[0081] Optionally, the radio access network node may configure one or more positioning and sensing resources in the positioning and sensing response message, wherein the configured resources meet the requirements of the positioning and sensing association indication.

[0082] In one embodiment, the location-aware response message includes node information of at least one transmitting and receiving node; the node information includes at least one of the following:
