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 understood as limiting the present disclosure.
[0037] To facilitate understanding, the terms involved in this application are first introduced.
[0038] 1. Transmission reception point (TRP)
[0039] Used to transmit data to or receive data from terminal devices.
[0040] 2. Centralized Unit (CU)
[0041] A monitoring client unit (CU) is used to execute computer instructions or monitor the system's ClientUnit. The CU is responsible for program flow management. The CU typically connects to multiple TRPs, aggregating information from each TRP to the CU for coordinated scheduling of radio resources. CUs exchange information via optical fiber, the core network, or the air interface.
[0042] FIG1 is a schematic diagram of a communication system based on distributed multi-user multiple input multiple output (MIMO) provided in an embodiment of the present disclosure. The communication system may include at least one TRP and at least one terminal device; wherein the number and form of devices shown in FIG1 are for example only and do not constitute a limitation on the embodiment of the present disclosure. In actual applications, one or more TRPs or one or more terminal devices may be included. The communication system shown in FIG1 is taken as an example including fifteen TRPs and one terminal device.
[0043] The terminal device in the embodiments of the present disclosure can be an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal device (MT), etc. The terminal device can be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), etc. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal device.
[0044] In one embodiment of the present disclosure, the terminal device may correspond to a TRP cluster, which may include at least one TRP, and some or all of the TRPs in the TRP cluster corresponding to the terminal device may be used to provide communication services for the terminal device; optionally, in one embodiment of the present disclosure, the TRP cluster corresponding to the terminal device may undergo cluster switching, or the TRPs included in the TRP cluster corresponding to the terminal device may change dynamically.
[0045] Optionally, the above-mentioned TRP cluster switching may refer to: the TRP cluster corresponding to the terminal device is switched from the current TRP cluster to another TRP cluster, that is: the cluster identification (Identity, ID) of the TRP cluster corresponding to the terminal device has changed. For example, assuming that at the first time point, the TRP cluster corresponding to the terminal device is TRP cluster #1, and at the second time point, the TRP cluster corresponding to the terminal device is changed to TRP cluster #2, it is considered that the TRP cluster corresponding to the terminal device has undergone cluster switching from the first time point to the second time point.
[0046] Optionally, the TRP included in the TRP cluster corresponding to the above-mentioned terminal device can change dynamically, which may mean that: the cluster identifier of the TRP cluster corresponding to the terminal device has not changed, but the TRP included in the TRP cluster corresponding to the terminal device has changed dynamically. For example, assuming that at a first time point, the TRP cluster corresponding to the terminal device is TRP cluster #1, and the TRPs included in TRP cluster #1 at the first time point are TRP#1, TRP#2, and TRP#3, at a second time point, the TRP cluster corresponding to the terminal device is still TRP cluster #1, but the TRPs included in TRP cluster #1 at the second time point are changed to TRP#4, TRP#2, and TRP#3, then it is considered that the TRP included in the TRP cluster corresponding to the terminal device has changed dynamically from the first time point to the second time point.
[0047] For example, referring to Figure 1, when a terminal device is at position A and position B, the corresponding TRP cluster is TRP cluster #1. However, the TRPs included in the TRP cluster #1 corresponding to the terminal device at position A are different from the TRPs included in the TRP cluster #1 corresponding to the terminal device at position B. In this case, it is considered that the TRPs included in the corresponding TRP cluster have dynamically changed when the terminal device moves from position A to position B. Furthermore, if the TRP cluster corresponding to the terminal device at position B is TRP cluster #1 and the TRP cluster corresponding to the terminal device at position C is TRP cluster #2, it is considered that the corresponding TRP cluster has undergone cluster switching when the terminal device moves from position B to position C.
[0048] It should be noted that the TRP cluster here is only a name provided for the description of the solution, and can also be expressed in other words, which is not limited by this application. In addition, the above-mentioned cluster identifier can be an identifier that uniquely indicates a TRP cluster, and can also be expressed in other words, which is not limited by this application.
[0049] Optionally, in one embodiment of the present disclosure, at the same time point, the terminal device corresponds to only one TRP cluster, and at different time points, the terminal device may correspond to different TRP clusters (i.e., the TRP cluster corresponding to the terminal device undergoes cluster switching). Alternatively, at different time points, the terminal device may correspond to the same TRP cluster, but the TRPs included in the TRP cluster are different (i.e., the TRPs included in the TRP cluster corresponding to the terminal device undergo dynamic changes).
[0050] Optionally, in one embodiment of the present disclosure, the TRP cluster corresponding to the terminal device may be switched to another cluster, including at least one of the following:
[0051] As the terminal device moves, the network device schedules the TRP cluster corresponding to the terminal device to switch clusters;
[0052] As the channel conditions of the terminal device change, the network device schedules the TRP cluster corresponding to the terminal device to switch clusters;
[0053] As the service requirements of the terminal device change, the network device schedules the TRP cluster corresponding to the terminal device to switch clusters.
[0054] Optionally, in one embodiment of the present disclosure, the dynamically changeable TRP included in the TRP cluster corresponding to the terminal device may include at least one of the following:
[0055] As the terminal device moves, the network device schedules the dynamic changes of the TRPs included in the TRP cluster corresponding to the terminal device;
[0056] As the channel conditions of the terminal device change, the network device schedules the dynamic changes of the TRPs included in the TRP cluster corresponding to the terminal device;
[0057] As the service requirements of the terminal device change, the network device schedules the dynamic changes of the TRPs included in the TRP cluster corresponding to the terminal device.
[0058] Optionally, the network device in the embodiment of the present disclosure is an entity on the network side for transmitting or receiving signals. For example, the network device 11 may be an evolved NodeB (eNB), a transmission reception point (TRP), a radio remote head (RRH), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present disclosure may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit or a central unit. The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, while the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.
[0059] Optionally, in one embodiment of the present disclosure, the above-mentioned "with the movement of the terminal device, the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the TRP included in the TRP cluster corresponding to the terminal device to undergo dynamic changes" may include: with the movement of the terminal device, the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the TRP included in the TRP cluster corresponding to the terminal device to undergo dynamic changes based on the TRP with better communication quality around the terminal device, such as, the network device may schedule the terminal device to switch to the TRP cluster to which the TRP with better communication quality around the terminal device belongs, or, the network device may schedule the TRP with better communication quality around the terminal device to the TRP cluster corresponding to the terminal device. Optionally, the TRP with better communication quality around the terminal device may be determined by the network device based on the report of the terminal device. In one embodiment of the present disclosure, the terminal device will measure the reference signal sent by the TRP around it to obtain the measurement result, and will report the measurement result to the network device, then the network device can determine the TRP with better communication quality around the terminal device based on the measurement result reported by the terminal device.
[0060] Optionally, in one embodiment of the present disclosure, the above-mentioned “as the channel condition of the terminal device changes, the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the dynamic change of the TRP included in the TRP cluster corresponding to the terminal device” may include: the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the dynamic change of the TRP included in the TRP cluster corresponding to the terminal device based on the channel conditions between each TRP and the terminal device, such as, the network device may schedule the terminal device to switch to the TRP cluster to which the TRP with better channel conditions belongs, or, the network device may schedule the TRP with better channel conditions to the TRP cluster corresponding to the terminal device. Optionally, the above-mentioned TRP with better channel conditions may be determined by the network device based on the report of the terminal device. In one embodiment of the present disclosure, the terminal device will measure the reference signal sent by the TRPs around it to obtain the measurement results, and will report the measurement results to the network device, then the network device can determine the TRP with better channel conditions based on the measurement results reported by the terminal device.
[0061] Optionally, in one embodiment of the present disclosure, the above-mentioned “as the service demand of the terminal device changes, the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the TRP included in the TRP cluster corresponding to the terminal device to undergo dynamic changes” may include: the network device schedules the TRP cluster corresponding to the terminal device to undergo cluster switching or schedules the TRP included in the TRP cluster corresponding to the terminal device to undergo dynamic changes based on the current service demand of the terminal device, wherein the service demand may be communication quality or communication rate, and different services correspond to different service demands. For example, when the service demand (such as communication rate) of the current service of the terminal device is high, the network device may schedule more TRPs to the TRP cluster corresponding to the terminal device, or the network device may schedule the terminal device to switch to a TRP cluster including more TRPs. When the service demand (such as communication rate) of the current service of the terminal device is low, in order to save resources, the network device may call out some TRPs from the TRP cluster corresponding to the terminal device, or the network device may schedule the terminal device to switch to a TRP cluster including fewer TRPs.
[0062] Optionally, in one embodiment of the present disclosure, when the network device determines that more TRPs need to undergo dynamic changes in the TRP cluster corresponding to the terminal device based on at least one of the mobile location of the terminal device, the channel conditions of the terminal device, and the business needs of the terminal device, the terminal device can directly determine to perform cluster switching on the TRP cluster corresponding to the terminal device, and make the switched TRP cluster include the required dynamically changing TRPs. When the network device determines that only a few TRPs need to undergo dynamic changes in the TRP cluster corresponding to the terminal device based on at least one of the mobile location of the terminal device, the channel conditions of the terminal device, and the business needs of the terminal device, the terminal device can directly determine to perform dynamic changes on the TRPs included in the TRP cluster corresponding to the terminal device without performing cluster switching on the TRP cluster corresponding to the terminal device.
[0063] Optionally, in one embodiment of the present disclosure, when the network device determines that a cluster switch occurs in the TRP cluster corresponding to the terminal device, the network device may send first configuration information to the terminal device. The first configuration information may be information related to the switched TRP cluster. Optionally, the first configuration information may configure the terminal device with resources that can be used for communication in the switched TRP cluster, so that the terminal device can communicate with the TRP in the switched TRP cluster based on the first configuration information, thereby completing related services.

[0081] Optionally, in another embodiment of the present disclosure, when the network device determines that the TRP included in the TRP cluster corresponding to the terminal device has changed dynamically, the network device may send second configuration information to the terminal device, and the second configuration information may be information related to the TRP that has changed dynamically in the TRP cluster corresponding to the terminal device. Optionally, the second configuration information may be used to configure the terminal device with resources that can be used for communication corresponding to the TRP that has changed dynamically, so that the terminal device can communicate with the TRP that has changed dynamically based on the second configuration information, thereby completing related services.

[0093] It can be seen from the foregoing that in one embodiment of the present disclosure, when the TRP cluster corresponding to the terminal device undergoes cluster switching, or when the TRP included in the TRP cluster corresponding to the terminal device undergoes dynamic changes, the network device will send first configuration information or second configuration information to the terminal device, so that the terminal device can determine the resources for communication corresponding to the switched TRP cluster or the dynamically changed TRP based on the first configuration information or the second configuration information, so that the terminal device can successfully communicate with the switched TRP cluster or the dynamically changed TRP based on the resources to complete related services and ensure communication stability.

[0097] In summary, in the distributed MIMO-based communication system provided by the embodiments of the present disclosure, a terminal device corresponds to a TRP cluster, which includes at least one TRP, and some or all of the TRPs in the TRP cluster corresponding to the terminal device are used to provide communication services for the terminal device; wherein the TRP cluster corresponding to the terminal device can undergo cluster switching, or the TRPs included in the TRP cluster corresponding to the terminal device can change dynamically. Thus, by switching the TRP cluster corresponding to the terminal device in real time, or by changing the TRPs in the TRP cluster corresponding to the terminal device in real time, the network device can always select the TRP that is most beneficial to the terminal device (e.g., with better communication quality) to provide communication services to the terminal device, thereby ensuring communication quality. Furthermore, in the present disclosure, since the TRP cluster corresponding to the terminal device can undergo cluster switching, or the TRPs included in the TRP cluster corresponding to the terminal device can change dynamically, when the terminal device moves, the network device can achieve real-time communication by switching the TRP cluster corresponding to the terminal device, or by dynamically changing the TRPs in the TRP cluster corresponding to the terminal device, without the need for frequent cell switching, thereby solving the problem of disconnection caused by frequent cell switching and ensuring communication stability.

[0122] For a detailed introduction to the configuration information, please refer to the description of the aforementioned embodiment, which will not be elaborated in this disclosure.
[0123] To sum up, in the configuration method provided in the embodiment of the present disclosure, the configuration information sent by the network device to the terminal device includes information related to the TRP cluster corresponding to the terminal device, so that the terminal device can successfully communicate with the TRP cluster corresponding to the terminal device based on the configuration information to complete related services, thereby ensuring communication stability.
[0124] Furthermore, in the present disclosure, the configuration information may be sent by the network device to the terminal device when a cluster switching occurs in the TRP cluster corresponding to the terminal device, or the configuration information may be sent by the network device to the terminal device when a dynamic change occurs in the TRP included in the TRP cluster corresponding to the terminal device. It can be seen from this that in the present disclosure, the TRP cluster corresponding to the terminal device may undergo cluster switching, or the TRP included in the TRP cluster corresponding to the terminal device may change dynamically, then the network device may switch the TRP cluster corresponding to the terminal device in real time, or change the TRP in the TRP cluster corresponding to the terminal device in real time, so as to always select the TRP that is most beneficial to the terminal device (such as having better communication quality) to provide communication services to the terminal device, thereby ensuring the communication quality.

[0152] FIG5 is a flow chart of a configuration method provided in another embodiment of the present disclosure. The configuration method is applied to the distributed MIMO-based communication system shown in FIG1 and is executed by a terminal device. As shown in FIG5 , the configuration method may include the following steps:
[0153] Step 501: Receive the reference signal sent by TRP.
[0154] Optionally, in one embodiment of the present disclosure, the terminal device may receive a reference signal sent by a TRP around it. Optionally, the TRP may be included in the TRP cluster corresponding to the terminal device, or may not be included in the TRP cluster corresponding to the terminal device.
[0155] Optionally, in one embodiment of the present disclosure, the terminal device may first receive the reference signal sent by the TRP, and then receive the configuration information sent by the network device; or, the terminal device may first receive the configuration information sent by the network device, and then receive the reference signal sent by the TRP; or, the terminal device may simultaneously receive the reference signal sent by the TRP and the configuration information sent by the network device.
[0156] Step 502: Measure a reference signal to obtain a measurement result.
[0157] The terminal device may perform a quality assessment of the channel between the terminal device and the TRP by measuring the reference signal sent by the TRP. Optionally, in one embodiment of the present disclosure, the terminal device may receive and measure the reference signal sent by the TRP based on the measurement configuration in the reference signal configuration information sent by the network device.
[0158] Step 503: Report the measurement results.
[0159] Optionally, the terminal device may report the measurement result based on the reporting configuration in the reference signal configuration information sent by the network device.
[0160] In addition, for a detailed description of steps 501 - 503 , reference may be made to the description of the aforementioned embodiment.
[0161] To sum up, in the configuration method provided by the embodiment of the present disclosure, the terminal device will report the measurement results of the reference signal sent by the terminal device to the network device, so that the network device can determine the TRP for providing communication services to the terminal device based on the measurement results reported by the terminal device. In this way, the TRP that is most beneficial to the terminal device (such as better communication quality) can always be selected to provide communication services to the terminal device, thereby ensuring the communication quality.
[0162] The following is an example of the communication system of the present disclosure:
[0163] The network architecture is shown in Figure 1 above, and the various parts are defined as follows:
[0164] TRP: Transmission Reception Point, used to transmit data to terminal devices or receive data from terminal devices.
[0165] CU: Central Unit, typically connected to multiple TRPs via optical fiber, aggregates information from each TRP to a central controller for coordinated scheduling of radio resources. CUs exchange information with each other via optical fiber or the core network.
[0166] TRP cluster: A collection of multiple TRPs configured by the network side for a terminal device. This collection is specific to the terminal device. Some or all TRPs in the TRP cluster participate in data transmission.
[0167] As shown in Figure 1, the network can configure a dedicated TRP cluster for each terminal device, and each terminal device can only be connected to one TRP cluster at a time. The TRP that transmits data for the terminal device can be selected from the TRP cluster, and the TRP serving the user can be implicitly indicated through the TCI without indicating it to the terminal.
[0168] As the user moves and channel conditions change, the number of TRPs contained in the TRP cluster to which the terminal device belongs may change, and the TRP cluster to which the terminal device belongs may also change. The same TRP can be connected to multiple CUs. When a TRP cluster update occurs (that is, the TRP included in the TRP cluster corresponding to the aforementioned terminal device changes dynamically) or switching occurs, the network side instructs the terminal by sending configuration information. The details are as follows:
[0169] 1. Network side
[0170] 1. When the TRP cluster to which the UE belongs is changed (i.e., when the aforementioned TRP cluster is switched), the network configures TRP cluster information for the UE. The configuration information includes at least one of the following:
[0171] a) TRP cluster ID information
[0172] b) TRP ID information contained in the TRP cluster
[0173] c) Reference signal configuration information of the TRP cluster
[0174] d) Wireless resource information
[0175] i. Frequency band and frequency point
[0176] ii. Bandwidth
[0177] iii. Time
[0178] e) Beam indication information for uplink and downlink traffic channels
[0179] i. Beam Index
[0180] ii.TCI Status ID
[0181] 2. Update the configuration of the TRP cluster, that is, update the TRP contained in the TRP cluster (that is, when the TRP included in the aforementioned TRP cluster changes dynamically). The configuration information can be any one of the following two items:
[0182] a) Configuration information includes all of 1 (corresponding to scenarios with frequent TRP changes)
[0183] b) The configuration information includes at least one of the following parts (corresponding to scenarios where TRP changes less frequently)
[0184] 2. Terminal side
[0185] 1. Receive network side configuration information
[0186] Receive the reference signal of the TRP in the TRP cluster, perform channel quality assessment, and complete the report according to the network configuration.
[0187] The disclosed network architecture enables continuous coverage. When a terminal device moves, the corresponding TRP cluster can be quickly updated to prevent disconnection. When the channel quality between the TRP serving the terminal device and the terminal device is poor, the network can control signaling to schedule switching to other TRPs within the TRP cluster to serve the terminal device, ensuring link quality and reducing handover latency. This network architecture solves the frequent cell handoffs and disconnection issues caused by handoffs in existing cellular networks.
