Description

Method, device and communication equipment for updating transmission and reception point TRP Technical Field

[0001] The present disclosure relates to the field of mobile communication technology, and in particular to a method, device and communication equipment for updating a sending and receiving point TRP. Background Art

[0002] With the continuous development of wireless communications, the requirements for communication capabilities are becoming increasingly stringent. For future application scenarios such as AR / VR, the Internet of Vehicles, and the Internet of Things, ultra-high-speed, ultra-low-latency, and ultra-large-bandwidth communications will become the norm. To meet this requirement, a growing number of new technologies are being proposed. Distributed MIMO (Multi-input Multi-output) technology means that multiple base stations can simultaneously serve a terminal, eliminating the need for cell handovers. Without the concept of cell boundaries, the user experience will be smoother. Furthermore, multiple TRPs serve a single UE (User Equipment), ensuring better signal quality and meeting the UE's high-speed, high-capacity service requirements. However, as the UE moves or channel conditions change, the TRP serving the UE can change at any time. Currently, the issue of TRP handover and update in this scenario has not been addressed.

[0037] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0038] With the continuous development of wireless communications, the demand for communication capabilities is increasing. For future application scenarios such as AR / VR, the Internet of Vehicles, and the Internet of Things, ultra-high-speed, ultra-low-latency, and ultra-large bandwidth communications will become the norm. To meet these requirements, a growing number of new technologies are being proposed. MIMO technology has ushered in a new era in the development and utilization of spatial resources in mobile communication systems.

[0039] Distributed MIMO is an evolution of traditional classic MIMO technology, expanding its application scope. It can be applied not only to single-cell cellular base station systems but can also replace multi-cell cellular base stations. Distributed MU-MIMO forms a cell-free mobile communication system, also known as cell-free technology. Cell-free technology can provide services to all users using the same time-frequency resources, eliminating the need for traditional inter-cell frequency division. System resources can be dynamically scheduled across all aspects of the system. This improves the flexibility of existing system resource allocation and significantly increases resource utilization.

[0040] For terminals, distributed MIMO technology means they can be served simultaneously by multiple base stations, eliminating cell handovers. The concept of cell boundaries is eliminated, resulting in a smoother user experience. Furthermore, multiple TRPs serving a single UE ensure better signal quality, meeting the UE's high-speed, high-capacity service requirements.

[0041] Distributed ultra-massive MIMO brings network equipment closer to the user. Structurally, no matter where the user equipment moves, there are antennas nearby to serve it, truly realizing a user-centric network structure. Therefore, the network protocols and architecture design above the physical layer must also be aligned with this. A multi-node collaborative transmission network architecture is needed to serve the user equipment.

[0042] Therefore, a user-centric distributed TRP networking solution is proposed. By configuring a unique TRP cluster for each UE, and the TRP cluster can be updated as the user moves and channel conditions change, it can provide better services for the user. The network architecture is shown in Figure 1, where TRP represents a transmission receiving point, which is used to transmit data to or receive data from the UE. CU represents a centralized unit, which is generally connected to multiple TRPs via optical fiber. The information of each TRP is aggregated to a central controller for coordinated scheduling of wireless resources. Different CUs exchange information via optical fiber or the core network. A TRP cluster is a collection of multiple TRPs configured for the UE by the network side. This collection is UE-specific, and some or all TRPs in the TRP cluster participate in data transmission.

[0043] As shown in Figure 1, the network can configure a dedicated TRP cluster for each UE. The TRP that transmits data for the UE is selected from the TRP cluster. As the user moves and channel conditions change, the number of TRPs in the TRP cluster can change, and the TRP status can also change. However, the issue of switching and updating TRPs within a TRP cluster remains unresolved.

[0044] To this end, the present disclosure proposes a method, device and communication equipment for updating the sending and receiving point TRP. By clarifying the signaling interaction process between CU-CU and CU-TRP, the TRP switching and update problems in the TRP cluster can be effectively solved.

[0045] It can be understood that the solution provided in the present disclosure can be used for the fifth generation mobile communication technology (Fifth Generation, 5G) and its subsequent communication technologies, such as the fifth generation mobile communication technology evolution (5G-advanced), the sixth generation mobile communication technology (Sixth Generation, 6G), etc., and is not limited in the present disclosure.

[0046] The following is a detailed introduction to the sending and receiving point TRP solution provided in this application with reference to the accompanying drawings.

[0047] Figure 2 illustrates a flow chart of a method for updating a transmit reception point (TRP) according to an embodiment of the present disclosure. As shown in Figure 2 , the method is performed by a first network device. In the present disclosure, the first network device includes a CU or CN, where a CU (Centralized Unit) refers to a centralized unit of a base station, and a CN (Core Network) refers to a core network device.

[0048] The method may include the following steps.

[0049] S101, updating the TRP state of the first TRP in the first TRP cluster scheduled by the first network device according to at least one of the measurement result reported by the UE, the communication service requested by the UE, and the network load.

[0050] Among them, the first TRP cluster is scheduled by the first network device, and the first TRP cluster is a set of multiple TRPs configured by the first network device for the UE. The first TRP can be any TRP in the first TRP cluster, including the TRP belonging to the first TRP cluster before the update and the TRP belonging to the first TRP cluster after the update.

[0051] It should be noted that the measurement results reported by the UE, the communication services requested by the UE, the network load, etc. may change as the UE moves. The network equipment needs to update each TRP serving the UE in real time during the movement of the UE.

[0052] In other words, the network side (CU / CN) can receive the measurement results reported by the terminal, and update the composition of the TRP cluster or the TRP status based on the measurement results reported by the terminal, terminal services, network load conditions and other information. The network load can refer to the traffic carried in the network and the number of users carried by the network equipment. When the network load is large, the area where the UE is located usually needs to schedule more TRP resources.

[0053] For example, the first network device receives the measurement result of the UE on the first TRP, and the relevant parameters are lower than the set threshold. It is considered that the measurement result of the first TRP is poor, and the TRP status of the first TRP is updated. For example, the first network device can decide to remove the first TRP from the first TRP cluster serving the UE.

[0054] Furthermore, in some embodiments of the present disclosure, the TRP state includes any one of the following: a first state, indicating that the first TRP changes from belonging to the first TRP cluster to belonging to the second TRP cluster; a second state, indicating that the first TRP changes from belonging to the first TRP cluster to a free state; a third state, indicating that the first TRP changes from belonging to the second TRP cluster to belonging to the first TRP cluster; a fourth state, indicating that the first TRP changes from a free state to belonging to the first TRP cluster.

[0055] The first TRP cluster is a TRP cluster that provides services to the UE, the second TRP cluster is a TRP cluster that does not provide services to the UE, and the free state is a TRP that does not provide services to any UE. The above TRP can be either a TRP entity or a TRP resource (time domain resources, frequency domain resources).

[0056] Specifically, the first state and the second state of the above-mentioned first TRP can be understood as the first TRP losing the qualification to serve the UE. After updating the first TRP to the first state / second state, the first TRP no longer belongs to the first TRP cluster. The first state indicates that the first TRP becomes a free state after being removed from the first TRP cluster, and the second state indicates that the first TRP is pulled from the first TRP cluster into the second TRP cluster.

[0057] Similarly, the third state and fourth state of the above-mentioned first TRP can be understood as the first TRP obtaining the qualification to serve the UE. After updating the third state / fourth state of the first TRP, the first TRP changes to belong to the first TRP cluster. The third state indicates that the first TRP is pulled from the second TRP cluster to the first TRP cluster. The fourth state indicates that the first TRP is pulled from the free state to the first TRP cluster, wherein the second TRP cluster may be scheduled by the first network device or by other network devices different from the first network device.

[0058] In summary, according to the method for updating the sending and receiving point TRP disclosed in the present invention, the first network device updates the TRP status of the first TRP in the first TRP cluster scheduled by the first network device based on the measurement results reported by the UE, the communication service requested by the UE, and at least one of the network load, which can effectively solve the TRP switching and update problems in the TRP cluster.

[0059] Figure 3 shows a flow chart of a method for updating a sending and receiving point TRP according to an embodiment of the present disclosure. The method is executed by a first network device, and based on the embodiment shown in Figure 2, as shown in Figure 3, the method may include the following steps.

[0060] S201, updating the TRP state of the first TRP in the first TRP cluster scheduled by the first network device according to at least one of the measurement result reported by the UE, the communication service requested by the UE, and the network load.

[0061] In an embodiment of the present disclosure, the TRP state includes any one of the following items: a first state, indicating that the first TRP changes from belonging to the first TRP cluster to belonging to the second TRP cluster; a second state, indicating that the first TRP changes from belonging to the first TRP cluster to a free state; a third state, indicating that the first TRP changes from belonging to the second TRP cluster to belonging to the first TRP cluster; a fourth state, indicating that the first TRP changes from a free state to belonging to the first TRP cluster, wherein the first TRP cluster is a TRP cluster that provides services for the UE, the second TRP cluster is a TRP cluster that does not provide services for the UE, and the free state is a TRP cluster that does not provide services for any UE.

[0062] The specific explanation of the above step 201 can refer to step 101 in the embodiment shown in FIG2 , which will not be described in detail in this disclosure.

[0063] S202: In response to the TRP state being the first state or the second state, releasing the wireless resources of the first TRP serving the first TRP cluster.

[0064] In an embodiment of the present disclosure, in response to the TRP state of the first TRP being the first state or the second state, that is, in response to the first TRP changing from belonging to the first TRP cluster to belonging to the second TRP cluster, or the first TRP changing from belonging to the first TRP cluster to belonging to the free state, the wireless resources of the first TRP serving the first TRP cluster are released, wherein the wireless resources mainly include time-frequency resources.

[0065] In other words, in response to the TRP being removed from the currently serving TRP cluster, the network device that schedules the TRP sends a release command to the TRP to release the wireless resources of the TRP serving the current TRP cluster.

[0066] In some embodiments of the present disclosure, the method further includes: in response to the TRP state being the first state or the second state, sending an update indication to the first TRP, wherein the update indication is used to indicate that the first TRP does not provide service for the UE. In other words, in response to the TRP being removed from the currently serving TRP cluster, the network device that schedules the TRP sends an update indication to the TRP, indicating that the TRP does not provide service for the current UE.

[0067] In some embodiments of the present disclosure, the method further includes: updating the configuration information of the first TRP cluster based on the TRP status of the first TRP; and sending the configuration information of the first TRP cluster to the UE.

[0068] Specifically, the first network device updates the configuration information of the first TRP cluster based on whether the TRP state of the first TRP is the first state or the second state, and sends the configuration information of the first TRP cluster to the UE, that is, informs the UE which TRPs are in the first TRP cluster after the update of the first TRP cluster, or in other words, informs the UE that the first TRP in the first TRP cluster has been removed.

[0069] Furthermore, the first network device can indicate the update result of the UE's first TRP cluster by indicating the TRP id, QCL group, and reference signal group, wherein the QCL group and the reference signal group are bound to the first TRP cluster, and the update of the TRP cluster can be implicitly indicated by updating the binding relationship between the QCL group, the reference signal group and the first TRP cluster.

[0070] In summary, according to the above embodiments, the TRP state of the first TRP in the first TRP cluster scheduled by the first network device is updated based on the measurement results reported by the UE, the communication service requested by the UE, and at least one of the network loads. In response to the TRP state being the first state or the second state, the wireless resources of the first TRP serving the first TRP cluster are released. When the TRP is removed from the TRP cluster serving the UE, the interaction process between the network device and the TRP is clarified from the network device side, effectively solving the TRP switching and update problems in the TRP cluster.

[0071] Figure 4 shows a flow chart of a method for updating a transmission reception point TRP according to an embodiment of the present disclosure. The method is executed by a first network device, and based on the embodiment shown in Figure 2, as shown in Figure 4, the method may include the following steps.

[0072] S301, updating the TRP state of the first TRP in the first TRP cluster scheduled by the first network device according to at least one of the measurement result reported by the UE, the communication service requested by the UE, and the network load.

[0073] In an embodiment of the present disclosure, the TRP state includes any one of the following items: a first state, indicating that the first TRP changes from belonging to the first TRP cluster to belonging to the second TRP cluster; a second state, indicating that the first TRP changes from belonging to the first TRP cluster to a free state; a third state, indicating that the first TRP changes from belonging to the second TRP cluster to belonging to the first TRP cluster; a fourth state, indicating that the first TRP changes from a free state to belonging to the first TRP cluster, wherein the first TRP cluster is a TRP cluster that provides services for the UE, the second TRP cluster is a TRP cluster that does not provide services for the UE, and the free state is a TRP cluster that does not provide services for any UE.

[0074] The specific explanation of the above step 301 can refer to step 101 in the embodiment shown in FIG2 , which will not be described in detail in this disclosure.

[0075] S302: In response to the TRP state being the third state, determine whether the second TRP cluster belongs to the first network device scheduling.

[0076] In an embodiment of the present disclosure, in response to the first TRP changing from belonging to the second TRP cluster to belonging to the first TRP cluster, where the second TRP cluster may be a TRP cluster scheduled by the first network device, or may be a TRP cluster scheduled by other network devices different from the first network device, it is necessary to determine whether the second TRP cluster belongs to the first network device scheduling.

[0077] In some embodiments of the present disclosure, the further embodiment includes: in response to the second TRP cluster belonging to the first network device scheduling, updating the configuration list of the second TRP cluster.

[0078] Specifically, the second TRP cluster is a TRP cluster scheduled by the first network device that does not serve the current UE. In other words, the second TRP cluster serves a different UE from the first TRP cluster, but they are both scheduled by the same network device. After moving the TRP from the second TRP cluster to the first TRP cluster, the first network device updates the configuration list of the second TRP cluster and notifies the target TRP cluster, which is the first TRP cluster.

[0079] It can be understood that for the second TRP cluster, the first TRP is in the third state, which is equivalent to removing the first TRP from the second TRP cluster. You can refer to the content in step S202. The first network device can also send the configuration information of the second TRP cluster to the UE served by the second TRP cluster to inform the UE that the first TRP has been removed from the second TRP cluster.

[0080] In some embodiments, it also includes: updating the configuration information of the first TRP cluster based on the TRP status of the first TRP; and sending the configuration information of the first TRP cluster to the UE.

[0081] In other words, for the first TRP cluster, the first TRP is in the third state, which is equivalent to moving into the first TRP. The first network device can update the configuration list of the first TRP cluster and send the configuration information of the first TRP cluster to the UE to inform the UE that the first TRP has joined the first TRP cluster.

[0082] Furthermore, the first network device can indicate the update result of the UE's first TRP cluster by indicating the TRP id, QCL group, and reference signal group, wherein the QCL group and the reference signal group are bound to the first TRP cluster, and the update of the TRP cluster can be implicitly indicated by updating the binding relationship between the QCL group, the reference signal group and the first TRP cluster.

[0083] In some other embodiments, the method further includes: in response to the second TRP cluster not belonging to the first network device scheduling, determining the second network device for scheduling the second TRP cluster; sending a TRP scheduling request to the second network device; receiving feedback information sent by the second network device, wherein the feedback information indicates whether the second network device agrees or disagrees with the TRP scheduling request; in response to the feedback information indicating that the second network device agrees to the TRP request, sending the configuration information of the first TRP to the second network device.

[0084] The second network device may be any other network device different from the first network device.

[0085] Specifically, when the second TRP cluster does not belong to the scheduling of the first network device, the first TRP needs to be switched from the TRP cluster scheduled by the second network device to the TRP cluster scheduled by the first network device. At this time, the first network device needs to send a TRP scheduling request to the second network device, that is, it needs to negotiate with the second network device. Regardless of whether the second network device agrees or not, it needs to give the first network device a feedback information. The feedback information indicates whether the second network device agrees or disagrees with the TRP scheduling request. When the second network device agrees to the TRP request, the configuration information of the first TRP is sent to the second network device.

[0086] It can be understood that since the first TRP is scheduled by the second network device before being updated, the configuration information configured by the first network device for the first TRP, that is, the updated configuration information, needs to be forwarded to the first TRP by the second network device.

[0087] In other words, when the TRP belongs to a TRP cluster scheduled by a different CU, the TRP needs to be moved from the TRP cluster scheduled by the target CU to the TRP cluster scheduled by the source CU. The source CU needs to negotiate with the target CU and maintain or update the configuration information of the TRP based on the negotiation results with the target CU, including the source CU sending a TRP scheduling request to the target CU directly or through the core network, the target CU feeding back to the source CU directly or through the core network, and sending an update indication to the TRP.

[0088] It can be understood that in the embodiment of the present disclosure, the first network device specifically serves as the source CU and the second network device specifically serves as the target CU. The method of the present disclosure is described from the side of the first network device, and conversely, is also applicable to the second network device.

[0089] In some embodiments of the present disclosure, the method further includes: updating the configuration information of the first TRP cluster based on the TRP status of the first TRP; and sending the configuration information of the first TRP cluster to the UE.

[0090] In other words, the first TRP is in the third state, which is equivalent to moving the first TRP into the first TRP cluster. The first network device can update the configuration list of the first TRP cluster, send the configuration information of the first TRP cluster to the UE, and inform the UE that the first TRP has joined the first TRP cluster.

[0091] Furthermore, the first network device can indicate the update result of the UE's first TRP cluster by indicating the TRP id, QCL group, and reference signal group, wherein the QCL group and the reference signal group are bound to the first TRP cluster, and the update of the TRP cluster can be implicitly indicated by updating the binding relationship between the QCL group, the reference signal group and the first TRP cluster.

[0092] In summary, according to the method for updating the sending and receiving point TRP disclosed in the present invention, the first network device updates the TRP status of the first TRP in the first TRP cluster scheduled by the first network device based on at least one of the measurement results reported by the UE, the communication service requested by the UE, and the network load. When the TRP is switched and updated in the TRP clusters of different UEs, and when the TRP is switched and updated in the TRP scheduled by different network devices, from the target network device side, the interaction process between the network device and the TRP, and the target network device and the source network device is clarified, effectively solving the TRP switching and update problem in the TRP cluster.

[0093] Figure 5 is a flow chart of a method for updating a sending and receiving point TRP according to an embodiment of the present disclosure.

[0097] S402: In response to the TRP state being the fourth state, update the configuration information of the first TRP.

[0098] In an embodiment of the present disclosure, in response to the first TRP changing from a free state to belonging to a first TRP cluster, since the first TRP does not provide services to any UE before the update, the configuration information of the first TRP can be directly updated.

[0099] Furthermore, the configuration information includes at least one of a system message, a frequency point, a frequency band, and an identifier of the TRP cluster to which it belongs.

[0100] In some embodiments of the present disclosure, the method further includes: updating the configuration information of the first TRP cluster based on the TRP status of the first TRP; and sending the configuration information of the first TRP cluster to the UE.

[0101] Specifically, based on the TRP state of the first TRP being the fourth state, which is equivalent to the first TRP being newly added to the first TRP cluster, the configuration information of the first TRP cluster is updated, and the configuration information of the first TRP cluster is sent to the UE, which can inform the UE that the first TRP has been newly added to the first TRP cluster.

[0102] Furthermore, the first network device can indicate the update result of the UE's first TRP cluster by indicating the TRP id, QCL group, and reference signal group, wherein the QCL group and the reference signal group are bound to the first TRP cluster, and the update of the TRP cluster can be implicitly indicated by updating the binding relationship between the QCL group, the reference signal group and the first TRP cluster.

[0103] In summary, according to the method for updating the sending and receiving point TRP disclosed in the present invention, the TRP state of the first TRP in the first TRP cluster scheduled by the first network device is updated according to the measurement results reported by the UE, the communication service requested by the UE, and at least one of the network load.

When the TRP changes from the free state to the TRP cluster providing services to the UE, the interaction process between the network device and the TRP is clarified from the network device side, effectively solving the TRP switching and update problems in the TRP cluster.

[0104] Figure 6 is a flow chart of a method for updating a sending and receiving point TRP according to an embodiment of the present disclosure. The method is executed by a first TRP, as shown in Figure 6, and the method may include the following steps.

[0105] S501: Receive an update indication and / or configuration information of a first TRP sent by a first network device or a second network device.

[0106] In an embodiment of the present disclosure, the first network device includes a CU or a CN, where a CU (Centralized Unit) refers to a centralized unit of a base station, and a CN (Core Network) refers to a core network device. The first TRP cluster is scheduled by the first network device, and the first TRP cluster is a set of multiple TRPs configured by the first network device for a UE. The first TRP is any TRP in the first TRP cluster, including TRPs belonging to the first TRP cluster before and after the update. The second network device is any other network device different from the first network device.

[0107] In some embodiments of the present disclosure, when the TRP state of the first TRP is the first state, the first TRP receives an update indication sent by the first network device and configuration information of the first TRP sent by the second network device.

[0108] The first state indicates that the first TRP has changed from belonging to the first TRP cluster to belonging to the second TRP cluster. The first TRP cluster is a TRP cluster that provides services to the UE, and the second TRP cluster is a TRP cluster that does not provide services to the UE. The second TRP cluster may be scheduled by the first network device to serve other UEs, or it may be scheduled by the second network device to serve other UEs.

[0109] Specifically, corresponding to the embodiment shown in FIG3 , when the first TRP changes from belonging to the first TRP cluster to belonging to the second TRP cluster, the first network device sends an update indication to the first TRP, instructing the first TRP not to provide services for the UE, and the first TRP receives the update indication sent by the first network device. For the second TRP cluster, it is determined whether the second TRP cluster belongs to the first TRP scheduling. If the second TRP cluster belongs to the first network device scheduling, the first network device updates the first TRP configuration information and notifies the second TRP cluster.

[0110] If the second TRP cluster does not belong to the first network device scheduling, determine the second network device that schedules the second TRP cluster, the second network device sends a TRP scheduling request to the first network device directly or through the core network, the first network device directly or through the core network feedback to the second network device, and sends an update indication to the first TRP, indicating that the first TRP does not provide service for the UE, the first TRP receives the update indication sent by the first network device, and the feedback information indicates whether the first network device agrees or disagrees with the TRP scheduling request. Since the first TRP was scheduled by the first network device before the update, when the first network device agrees to the TRP request, the configuration information configured by the second network device for the first TRP, that is, the updated configuration information, needs to be forwarded to the first TRP by the first network device, specifically including: the second network device sends the configuration information of the first TRP to the first network device, the first network device forwards the configuration information of the first TRP sent by the second network device to the first TRP, and the first TRP receives the configuration information of the first TRP sent by the second network device.

[0111] In some embodiments, when the TRP state of the first TRP is the second state, the first TRP receives an update indication sent by the first network device.

[0112] Among them, the second state indicates that the first TRP changes from belonging to the first TRP cluster to the free state. The first TRP cluster is a TRP cluster that provides services for UEs, and the free state is a TRP cluster that does not provide services for any UE.

[0113] Specifically, corresponding to the embodiment shown in Figure 3, when the first TRP changes from belonging to the first TRP cluster to the free state, the first network device sends an update indication to the first TRP, instructing the first TRP not to provide services for the UE, and the first TRP receives the update indication sent by the first network device.

[0114] In some embodiments, when the TRP state of the first TRP is the third state, the first TRP receives an update indication sent by the second network device and configuration information of the first TRP sent by the first network device.

[0115] Among them, the third state indicates that the first TRP changes from belonging to the second TRP cluster to belonging to the first TRP cluster. The first TRP cluster is a TRP cluster that provides services for the UE, and the second TRP cluster is a TRP cluster that does not provide services for the UE.

[0116] Specifically, corresponding to the embodiment shown in Figure 4, when the first TRP changes from belonging to the second TRP cluster to belonging to the first TRP cluster, it is determined whether the second TRP cluster belongs to the first TRP scheduling. If the second TRP cluster belongs to the first network device scheduling, the first network device updates the configuration list of the first TRP cluster and notifies the target TRP cluster, that is, the first TRP cluster.

[0117] If the second TRP cluster does not belong to the first network device scheduling, determine the second network device that schedules the second TRP cluster, the first network device sends a TRP scheduling request to the second network device directly or through the core network, the second network device directly or through the core network feedback to the first network device, and sends an update indication to the first TRP, indicating that the first TRP does not provide service for the UE, the first TRP receives the update indication sent by the second network device, and the feedback information indicates whether the second network device agrees or disagrees with the TRP scheduling request. Since the first TRP was scheduled by the second network device before the update, when the second network device agrees to the TRP request, the configuration information configured by the first network device for the first TRP, that is, the updated configuration information, needs to be forwarded to the first TRP by the second network device, specifically including: the first network device sends the configuration information of the first TRP to the second network device, the second network device forwards the configuration information of the first TRP sent by the first network device to the first TRP, and the first TRP receives the configuration information of the first TRP sent by the first network device.

[0118] In some embodiments, when the TRP state of the first TRP is the fourth state, the first TRP receives configuration information of the first TRP sent by the first network device.

[0119] Among them, the fourth state indicates that the first TRP changes from a free state to belonging to a first TRP cluster. The first TRP cluster is a TRP cluster that provides services for UEs, and the free state is a TRP cluster that does not provide services for any UE.

[0120] Specifically, corresponding to the embodiment shown in Figure 5, when the first TRP changes from a free state to belonging to the first TRP cluster, it is equivalent to the first TRP cluster scheduled by the first network device newly adding the first TRP. The first network device can directly update the configuration information of the first TRP, and the first TRP receives the configuration information of the first TRP sent by the first network device. The configuration information includes system messages, frequencies, frequency bands, TRP cluster IDs, etc.

[0121] It should be noted that the above-mentioned TRP can be either a TRP entity or TRP resources (time domain resources, frequency domain resources).

[0122] In summary, according to the updating method of the sending and receiving point TRP disclosed in the present invention, the first TRP receives the update indication and / or the configuration information of the first TRP sent by the first network device or the second network device. From the TRP side, the interaction process between the network device and the TRP is clarified, effectively solving the TRP switching and update problems in the TRP cluster.

[0123] An embodiment of the present disclosure provides a method for updating a sending and receiving point TRP, which is executed by a UE and includes the following steps: receiving a reference signal of a first TRP and performing reference signal measurement; reporting the measurement results; and receiving configuration information of a first TRP cluster sent by a first network device.

The first network device updates the TRP status of the first TRP based on the measurement result reported by the UE. For example, if the relevant parameters in the measurement result are lower than the set threshold, it is considered that the UE's measurement result of the first TRP is poor. The first network device updates the TRP status of the first TRP and removes the first TRP from the first TRP cluster serving the UE.

[0126] In some embodiments of the present disclosure, corresponding to the embodiments shown in Figures 3 / 4 / 5 on the first network device side, the first network device updates the configuration information of the first TRP cluster based on the TRP status of the first TRP, sends the configuration information of the first TRP cluster to the UE, and the UE receives the configuration information of the first TRP cluster. For example, in response to the first TRP changing from belonging to the first TRP cluster to belonging to the free state, after updating the configuration information of the first TRP cluster, the first TRP is removed from the first TRP cluster, and the first network device informs the UE of the update result of the first TRP cluster by sending the updated configuration information of the first TRP cluster.

[0127] Furthermore, the first network device can indicate the update result of the UE's first TRP cluster by indicating the TRP id, QCL group, and reference signal group, wherein the QCL group and the reference signal group are bound to the first TRP cluster, and the update of the TRP cluster can be implicitly indicated by updating the binding relationship between the QCL group, the reference signal group and the first TRP cluster.
