[0035] Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0036] The application scenarios of mobile network communication technology in real life are expanding, for example, the emergence of application scenarios such as future-oriented augmented reality (AR), virtual reality (VR), and more new Internet applications (such as Internet of Vehicles, Internet of Things, etc.). The requirements of each application scenario for network communication rate, delay, bandwidth, and other capabilities are getting higher and higher.

[0037] In specific application scenarios, different service types have different requirements for wireless communication technology. For example, the demand of enhanced Mobile Broad Band (eMBB) service focuses on large bandwidth and high rate; the demand of Ultra Reliable Low Latency Communication (URLLC) service focuses on high reliability and low latency; and the demand of massive Machine Type Communication (mMTC) service focuses on a large number of connections. It can be seen that the new generation of wireless communication system needs flexible and configurable design to support the transmission requirements of multiple service types.

[0038] In order to meet the communication requirements of ultra-high rate, ultra-low latency, and ultra-large bandwidth, MIMO technology opens a new era of spatial resource development and utilization of mobile communication systems. Distributed MIMO is developed on the basis of traditional classic MIMO technology and expands the application range of traditional MIMO. It can not only be applied to single-cell cellular base station systems, but also further replace multi-cell cellular base stations to form a cell-free mobile communication system in the form of distributed MU-MIMO, that is, cell-free technology. Cell-free can provide services for all users under the condition of the same time-frequency resources, without the traditional sense of inter-cell frequency division, and the system resources can be dynamically scheduled in all aspects. In this way, the flexibility of existing system resource configuration can be improved, and the utilization rate of resources can be greatly improved.

[0039] For the terminal, distributed MIMO technology means that multiple base stations will serve themselves at the same time, and there is no cell switching. Without the concept of cell boundary, the user experience will be smoother. And multiple TRPs serve a UE, and the signal quality is better guaranteed, which can meet the UE's high-rate and high-capacity service requirements.

[0040] In the distributed MIMO system, the cooperative transmission between multiple TRPs is the key to system performance improvement, and how to select a suitable TRP set to serve the terminal is a problem to be solved.

[0041] Therefore, the present disclosure proposes a communication method, device and system based on a distributed system, aiming to solve the problem of cooperative transmission of multiple TRPs in distributed MIMO. The present disclosure can select a suitable part of TRPs in the multiple TRP set as a service node to adapt to the Cyclic Prefix (CP) of the terminal. By serving the terminal with multiple TRPs, the signal reception quality of the terminal can be improved.

[0042] It can be understood that the scheme provided by the present disclosure can be used in the fifth generation mobile communication technology (5G) and subsequent communication technologies, such as the fifth generation mobile communication technology evolution (5G-advanced), the sixth generation mobile communication technology (6G), and the like, which are not limited in the present disclosure.

[0043] The communication method and device based on a distributed system provided by the present application will be described in detail below in combination with the drawings.

[0044] Figure 1 A flowchart of a communication method based on a distributed system according to an embodiment of the present disclosure is shown. The method is performed by a network device. In an embodiment of the present disclosure, the network device can be understood as a base station, specifically, gNB (next Generation Node B) in the 5G communication scenario.

[0045] As Figure 1 shown, the method can include the following steps.

In other words, the network device can configure the measurement configuration information, including configuring the measurement TRP identifier set, configuring the measurement quantity, and configuring the measurement parameter.

[0050] In an embodiment of the present disclosure, the measurement quantity can be understood as the type of reference signal that needs to be measured, for example, at least one of the following: signal to interference plus noise ratio (SINR), reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), received signal strength indication (RSSI).

[0051] In an embodiment of the present disclosure, the measurement parameter includes a time of arrival range and a reference signal quality threshold. The time of arrival range is a range in which the time of arrival of the recommended TRP should fall, and the time of arrival includes a single-path time of arrival or a multi-path time of arrival. In other words, the network device can configure a time value, for example, 5s, to assist the UE in deciding the TRP that meets the condition, for example, the time of arrival of the TRP falls within the configured time value range.

[0052] The reference signal quality threshold is a minimum value that the received energy of the reference signal of the measured TRP at the UE should meet. In other words, the network device can configure a threshold value for the above measurement quantity to assist the UE in deciding the TRP that meets the condition. For example, the network device indicates to the UE that the measurement quantity is RSRP and indicates that the reference signal quality threshold is -80dBm, and the UE can select the TRP whose reference signal meets the condition.

[0053] S103, sending the reference signal of the measured TRP corresponding to the measured TRP identification set.

[0054] The network device can send the reference signal of the measured TRP corresponding to the measured TRP identification set to the UE for measurement by the UE.

[0055] S104, receiving the identification of the recommended TRP or the reference signal of the recommended TRP.

[0056] In an embodiment of the present disclosure, the recommended TRP is the measured TRP that meets the condition determined by the UE according to the measurement quantity and the measurement parameter.

[0057] As described above, the UE can select the TRP that meets the condition as the recommended TRP according to the indication of the network device, and report the identification of the recommended TRP or the identification of the reference signal of the recommended TRP to the network device.

[0058] S105, determining the transmission TRP and / or reception TRP for subsequent use according to the identification of the recommended TRP or the reference signal of the recommended TRP.

[0059] In an embodiment of the present disclosure, the network device can select a suitable TRP as the transmission TRP and / or reception TRP for subsequent use according to the identification of the recommended TRP reported by the UE, to perform transmission and reception of signals. It can be understood that the principle of the network device determining the transmission TRP and / or reception TRP for subsequent use can be to consider the multi-user case and ensure that the overall energy efficiency is maximized.

[0060] In summary, according to the method proposed in the present disclosure, the network device can determine and send the measurement configuration information to the UE, the measurement configuration information including a measurement transmission / reception point (TRP) identification set, a measurement quantity, and a measurement parameter, sending a reference signal of a measurement TRP corresponding to the measurement TRP identification set, receiving an identification of a recommended TRP or a recommended TRP reference signal, the recommended TRP being a measurement TRP satisfying a condition determined by the UE according to the measurement quantity and the measurement parameter, and determining a subsequent transmission TRP and / or reception TRP according to the identification of the recommended TRP or the recommended TRP reference signal. The scheme proposed in the present disclosure solves the problem of multiple TRP cooperative transmission in distributed MIMO, selects appropriate part of TRPs in the multi-TRP set as service nodes to adapt the CP of the terminal, and improves the signal reception quality of the terminal by serving the terminal with multiple TRPs.

[0074] In embodiments of the present disclosure, the recommended TRP is a TRP determined by the UE according to the configuration of the network device to meet the conditions, for example, a TRP meeting the arrival time range condition and the reference quality signal threshold condition indicated by the network device. In some optional embodiments, the quantity of the recommended TRP can be determined according to the indication of the network, or the UE can report all of them.

[0076] In some optional embodiments of the present disclosure, the network device can receive the measurement result of the recommended TRP in addition to receiving the recommended TRP or the recommended TRP reference signal identifier. For example, the UE determines the measurement result, i.e., the measurement value, of the corresponding measurement quantity by measuring the reference signal of the measured TRP, and reports the measurement result together with the recommended TRP or the recommended TRP reference signal identifier to the network device.

[0077] It can be understood that this step S206 is an optional step, and it can be performed simultaneously with step S205 or separately, and the timing of its execution is not limited in the present disclosure.

The UE includes, but is not limited to, a smart terminal device, a cellular phone, a wireless device, a handset, a mobile unit, a vehicle, a vehicle-mounted device, etc.

[0082] As shown in Figure 3 , the method can include the following steps.

[0084] In an embodiment of the present disclosure, the measurement configuration information includes a measurement transmission / reception point (TRP) identifier set, a measurement quantity, and a measurement parameter.

[0085] In an embodiment of the present disclosure, the measurement TRP identifier set includes at least one of an identifier of a measurement TRP, a resource identifier of a reference signal corresponding to the measurement TRP, and / or a sequence identifier.

[0086] In an embodiment of the present disclosure, the measurement quantity can be understood as a kind of reference signal that needs to be measured, for example, including at least one of a signal-to-interference-plus-noise ratio (SINR), a reference signal received power (RSRP), a reference signal received quality (RSRQ), and a received signal strength indication (RSSI).

The time of arrival range is a range in which the time of arrival of the recommended TRP should fall, and the time of arrival includes a single-path time of arrival or a multi-path time of arrival.

[0089] S302, receiving the reference signal of the measured TRP corresponding to the measured TRP identification set sent by the network device.

[0090] In an embodiment of the present disclosure, the UE can receive the reference signal of the measured TRP sent by the network device and measure it.

[0091] S303, determining the measurement result of the measurement quantity of the reference signal, and determining the measured TRP that meets the condition as the recommended TRP according to the measurement result and the measurement parameter.

[0092] In an embodiment of the present disclosure, the UE receives the configuration information of the network, including the measurement quantity and the measurement parameter, and for the reference signal of the measured TRP sent by the network device, the UE can determine the measurement result of the measurement quantity of the reference signal, and compare the measurement result with the measurement parameter indicated by the network device, so as to determine the measured TRP that meets the condition as the recommended TRP.

[0093] S304, sending the identification of the recommended TRP or the recommended TRP reference signal to the network device.

[0094] In an embodiment of the present disclosure, the UE sends the identification of the recommended TRP or the recommended TRP reference signal to the network device, so as to assist the network device in determining the subsequent transmission TRP and / or reception TRP.

[0095] In summary, according to the method proposed in the present disclosure, the UE can receive the measurement configuration information sent by the network device, the measurement configuration information including a measurement transmission / reception point (TRP) identification set, a measurement quantity, and a measurement parameter; receive the reference signal of the measurement TRP corresponding to the measurement TRP identification set sent by the network device; determine the measurement result of the measurement quantity of the reference signal, and determine the measurement TRP meeting the condition as a recommended TRP according to the measurement result and the measurement parameter; and send the identification of the recommended TRP or the reference signal of the recommended TRP to the network device, the recommended TRP being used to assist the network device in determining the transmission TRP and / or the reception TRP used subsequently. The scheme proposed in the present disclosure solves the problem of multiple TRP cooperative transmission in distributed MIMO, selects appropriate part of the TRP in the multi-TRP set as a service node to adapt the CP of the terminal, and improves the signal reception quality of the terminal by using the multi-TRP to serve the terminal.

[0096] Figure 4 A flowchart of a communication method based on a distributed system according to an embodiment of the present disclosure is shown in FIG. 4. As shown in FIG. 4, the method is performed by a UE. Based on the embodiment shown in FIG. 3, the method can include the following steps. Figure 3 Figure 3

[0097] S401, receiving measurement configuration information sent by a network device.

[0098] S402, receiving the reference signal of the measurement TRP corresponding to the measurement TRP identification set sent by the network device.

[0099] The principles of the above steps S401 to S402 are the same as those of steps S301 to S302 in the embodiment shown in FIG. 3, and reference can be made to the description of the above embodiments, which will not be described herein again. Figure 3

[0100] S403, determining the measurement result of the measurement quantity of the reference signal, and determining the measurement TRP meeting the condition as a recommended TRP according to the measurement result and the measurement parameter.

[0101] Specifically, step S403 can include: determining the value of the measurement quantity of the reference signal as the measurement result; and determining the measurement TRP meeting the condition as a recommended TRP according to the measurement result and the measurement parameter.

[0102] The UE receives the measurement configuration information from the network device, which includes the measurement quantity and the measurement parameter. The UE can measure the received reference signal, for example, the measurement quantity indicated by the network device is RSRP, and the measurement parameter includes the arrival time range and the reference signal quality threshold, for example, the arrival time range is 5s and the reference signal quality threshold is -80dBm. Then, the UE can determine the TRP meeting the condition as a recommended TRP.

[0103] ​​​The UE can determine a measurement TRP, in which a reference signal arrival time of the measurement TRP falls within the arrival time range, as a candidate TRP.

[0104] For example, the network device indicates that the measurement TRP set includes TRP 1, TRP 2, and TRP 3. The measurement TRP can arrive at the UE through multiple paths, for example, TRP 1 corresponds to one path, TRP 2 corresponds to three paths, and TRP 3 corresponds to five paths. The UE determines the TRP whose arrival time falls within the arrival time range of 5s indicated by the network device as a candidate TRP. The arrival time of the reference signal includes single-path arrival time or multi-path arrival time. In other words, if the measurement TRP corresponds to multiple paths, the multi-path arrival time of the TRP falls within the arrival time range, and the TRP can be determined as a recommended TRP.

[0105] It should be understood that the arrival time range indicated by the network to the UE can be understood as a sliding time period. In other words, the network device only indicates the length of the arrival time range, and does not need to indicate the start and end times of the arrival time range. How the UE determines the start and end times of the arrival time range is not limited, and can be determined according to specific application conditions.

[0106] In an embodiment of the present disclosure, the UE can determine a candidate TRP whose measurement result is greater than or equal to a reference signal quality threshold as a recommended TRP. For example, in the above example in the present disclosure, the measurement quantity indicated by the network device is RSRP, and the reference signal quality threshold is -80dBm.
