[0036] 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.

[0037] The application scenarios of mobile network communication technology in real life are constantly expanding. For example, with the emergence of future-oriented application scenarios such as augmented reality (AR), virtual reality (VR), and more new Internet applications (such as the Internet of Vehicles and the Internet of Things), each application scenario has increasingly higher requirements for network communication capabilities such as speed, latency, and bandwidth.

[0038] In specific application scenarios, different service types have different requirements for wireless communication technologies. For example, enhanced mobile broadband (eMBB) services focus on large bandwidth and high speeds; ultra-reliable low-latency communication (URLLC) services require high reliability and low latency; and massive machine-type communication (mMTC) services require massive connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission needs of various service types.

[0039] To meet communication requirements such as ultra-high speeds, ultra-low latency, and ultra-large bandwidth, MIMO technology has ushered in a new era in the development and utilization of spatial resources in mobile communication systems. Distributed MIMO, developed based on traditional classic MIMO technology, expands 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, creating a cellular-free mobile communication system in the form of distributed MU-MIMO, 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 in all aspects. 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] In a distributed MIMO system, collaborative transmission between multiple TRPs is the key to improving system performance. How to select a suitable TRP set to serve the terminal is an urgent problem to be solved.

[0042] To this end, the present disclosure proposes a communication method, device, and system based on a distributed system, aiming to solve the problem of coordinated transmission of multiple Transmitter Relay Protocols (TRPs) in distributed MIMO. The present disclosure can select appropriate TRPs from a set of multiple TRPs as service nodes to adapt the cyclic prefix (CP) of the terminal. By serving the terminal with multiple TRPs, the signal reception quality of the terminal can be improved.

[0043] 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.

[0044] The following is a detailed introduction to the distributed system-based communication method and device provided by this application with reference to the accompanying drawings.

[0045] Figure 1 illustrates a schematic flow diagram of a distributed system-based communication method according to an embodiment of the present disclosure. The method is performed by a network device. In the embodiments of the present disclosure, the network device can be understood as a base station, specifically a gNB (next generation Node B) in a 5G communication scenario.

[0046] As shown in FIG1 , the method may include the following steps.

[0047] S101: Determine measurement configuration information.

[0048] In the embodiment of the present disclosure, the measurement configuration information includes a measurement transmission / reception point TRP identifier set, a measurement amount, and a measurement parameter. In other words, the network device can configure the measurement configuration information, including configuring the measurement TRP identifier set, configuring the measurement amount, and configuring the measurement parameter.

[0050] In one embodiment of the present disclosure, the measurement TRP identifier set includes: an identifier of the measurement TRP, a resource identifier of a reference signal corresponding to the measurement TRP, and / or a sequence identifier.

[0051] In one 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), and Received Signal Strength Indication (RSSI).

[0052] In one embodiment of the present disclosure, the measurement parameters include an arrival time range and a reference signal quality threshold. The arrival time range is the range within which the recommended TRP should fall, and the arrival time includes single-path arrival time and multipath arrival time. In other words, the network device can configure a time value, such as 5 seconds, to assist the UE in determining a TRP that meets the requirements, such as a TRP whose arrival time falls within the configured time value range.

[0053] The reference signal quality threshold is the minimum value that the UE's received energy of the reference signal used to measure the TRP must meet. In other words, the network device can configure a threshold for the aforementioned measurement quantity to assist the UE in determining a TRP that meets the requirements. For example, if the network device indicates to the UE the RSRP measurement quantity and instructs the UE to set the reference signal quality threshold to -80dBm, the UE can select a TRP for which the reference signal meets the requirements.

[0054] S103: Send a reference signal of the measured TRP corresponding to the measured TRP identifier set.

[0055] The network device may send a reference signal of the measurement TRP corresponding to the measurement TRP identifier set to the UE for measurement of the UE.

[0056] S104, receiving an identifier of a recommended TRP or a recommended TRP reference signal.

[0057] In the embodiment of the present disclosure, the recommended TRP is a measurement TRP that meets the conditions and is determined by the UE according to the measurement amount and measurement parameters.

[0058] As described above, the UE can select a TRP that meets the conditions as the recommended TRP according to the instructions of the network device, and report the identifier of the recommended TRP or the identifier of the recommended TRP reference signal to the network device.

[0059] S105, determine the subsequent sending TRP and / or receiving TRP based on the identifier of the recommended TRP or the recommended TRP reference signal.

[0060] In an embodiment of the present disclosure, the network device may select an appropriate TRP as a subsequent transmit TRP and / or receive TRP based on the recommended TRP identifier reported by the UE to transmit and receive signals. It is understood that the principle for the network device to determine the subsequent transmit TRP and / or receive TRP may be to consider the multi-user situation and ensure that the overall energy efficiency is maximized.

[0061] In summary, according to the method proposed in the present disclosure, the network device can determine and send measurement configuration information to the UE, the measurement configuration information includes a measurement sending / receiving point TRP identifier set, a measurement amount, and a measurement parameter, sends a reference signal of the measurement TRP corresponding to the measurement TRP identifier set, receives an identifier of a recommended TRP or a recommended TRP reference signal, the recommended TRP is a measurement TRP that meets the conditions determined by the UE based on the measurement amount and the measurement parameter, and determines the subsequent sending TRP and / or receiving TRP based on the identifier of the recommended TRP or the recommended TRP reference signal. The solution proposed in the present disclosure solves the problem of collaborative transmission of multiple TRPs in distributed MIMO, by selecting a suitable portion of TRPs in the multiple TRP sets as service nodes to adapt to the CP of the terminal, and serving the terminal through multiple TRPs, thereby improving the signal reception quality of the terminal.

[0062] Figure 2 shows a flow chart of a communication method based on a distributed system according to an embodiment of the present disclosure. The method is applied to a network device, based on the embodiment shown in Figure 1, as shown in Figure 2, the method may include the following steps.

[0063] S201: Determine measurement configuration information.

[0064] The network device can configure measurement configuration information, including configuring a measurement TRP identifier set, configuring a measurement quantity, and configuring measurement parameters.

[0065] Specifically, there are several ways to configure the measurement TRP set: 1) configure the measurement TRP identifier; 2) configure the resource identifier of the reference signal corresponding to the TRP; 3) configure the sequence identifier of the reference signal corresponding to the TRP.

[0066] The network device can be configured with any of the measurement quantities RSRP, RSRQ, SINR, and RSSI. The network device can also be configured with the measurement parameter arrival time range and reference signal quality threshold. This is as described in the embodiment of Figure 1 and will not be repeated here.

[0067] In some optional embodiments, the network device may further configure the type and / or length of the reference CP, which will not be described in detail in this disclosure.

[0068] S202: Send measurement configuration information to user equipment UE.

[0069] S203: Send a reference signal of the measured TRP corresponding to the measured TRP identifier set.

[0070] For the description of the above steps 201 - S203 , reference may be made to the description of steps S101 - S103 in the embodiment shown in FIG. 1 .

[0071] S204: Indicate the recommended TRP quantity threshold to the UE.

[0072] In an embodiment of the present disclosure, the network device may indicate to the UE a threshold value for the number of recommended TRPs, i.e., a maximum number of TRPs to be reported. The UE may report TRP identifiers less than or equal to the threshold value according to the network's instruction.

[0073] It should be understood that step S204 is an optional step, and its occurrence order can be at any time before receiving the identification of the recommended TRP or the recommended TRP reference signal, and is not limited in this disclosure.

[0074] S205, receiving an identifier of a recommended TRP or a recommended TRP reference signal.

[0075] In the embodiments of the present disclosure, the recommended TRP is a TRP that satisfies conditions determined by the UE based on the configuration of the network device, for example, a TRP that satisfies the arrival time range condition and the reference quality signal threshold condition indicated by the network device. In some optional embodiments, the number of recommended TRPs can be determined based on the instructions of the network, or the UE can report all of them.

[0076] S206: Receive a measurement result of the recommended TRP, where the measurement result is a value of a measurement quantity of a reference signal corresponding to the recommended TRP.

[0077] In some optional embodiments of the present disclosure, in addition to receiving the identifier of the recommended TRP or the recommended TRP reference signal, the network device may also receive a measurement result of the recommended TRP. For example, the UE determines the measurement result of the corresponding measurement quantity, i.e., the measurement value, by measuring the reference signal for measuring the TRP, and reports the measurement result together with the identifier of the recommended TRP or the recommended TRP reference signal to the network device.

[0078] It can be understood that step S206 is an optional step, and it can be performed simultaneously with step S205 or separately, and the execution sequence thereof is not limited in the present disclosure.

[0079] S207, determining the subsequent sending TRP and / or receiving TRP based on the identification and measurement results of the recommended TRP or the recommended TRP reference signal.

[0080] In an embodiment of the present disclosure, the network device can determine a suitable TRP for sending and receiving subsequent signals based on the recommended TRP or the identifier of the recommended TRP reference signal reported by the UE and the corresponding measurement results.

[0081] In summary, according to the method proposed in the present disclosure, the network device can determine and send measurement configuration information to the UE, the measurement configuration information includes a measurement sending / receiving point TRP identifier set, a measurement amount, and a measurement parameter, send a reference signal of the measurement TRP corresponding to the measurement TRP identifier set, receive a recommended TRP or an identifier of a recommended TRP reference signal, the recommended TRP is a measurement TRP that meets the conditions determined by the UE based on the measurement amount and the measurement parameter, and determine the subsequent sending TRP and / or receiving TRP based on the identifier of the recommended TRP or the recommended TRP reference signal. The solution proposed in the present disclosure solves the problem of collaborative transmission of multiple TRPs in distributed MIMO, by selecting a suitable portion of TRPs as service nodes in multiple TRP sets to adapt to the CP of the terminal, and serving the terminal through multiple TRPs, thereby improving the signal reception quality of the terminal. The network device in the present disclosure can also indicate the maximum reporting number to the UE, thereby further optimizing communication performance and resource allocation and reducing waste. The network device in the present disclosure can also receive the measurement results reported by the UE, and make decisions based on the measurement results, further improving accuracy.

[0082] Figure 3 is a flow chart of a distributed system-based communication method according to an embodiment of the present disclosure. The method is performed by user equipment (UE). UEs include, but are not limited to, smart terminal devices, cellular phones, wireless devices, handsets, mobile units, vehicles, and in-vehicle devices.

[0083] As shown in FIG3 , the method may include the following steps.

[0084] S301: Receive measurement configuration information sent by a network device.

[0085] In an embodiment of the present disclosure, the measurement configuration information includes a measurement sending / receiving point TRP identifier set, a measurement quantity, and a measurement parameter.

[0086] In one embodiment of the present disclosure, the measurement TRP identifier set includes: an identifier of the measurement TRP, a resource identifier of a reference signal corresponding to the measurement TRP, and / or a sequence identifier.

[0087] In one 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 signal to interference plus noise ratio SINR, reference signal received power RSR), reference signal received quality RSRQ, and received signal strength indication RSSI.

[0088] In one embodiment of the present disclosure, the measurement parameters include an arrival time range and a reference signal quality threshold. The arrival time range is the range within which the recommended TRP should fall, and the arrival time includes single-path arrival time and multipath arrival time. In other words, the network device can configure a time value, such as 5 seconds, to assist the UE in determining a TRP that meets the requirements, such as a TRP whose arrival time falls within the configured time value range.

[0089] The reference signal quality threshold is the minimum value that the UE's received energy of the reference signal used to measure the TRP must meet. In other words, the network device can configure a threshold for the aforementioned measurement quantity to assist the UE in determining a TRP that meets the requirements. For example, if the network device indicates to the UE the RSRP measurement quantity and instructs the UE to set the reference signal quality threshold to -80dBm, the UE can select a TRP for which the reference signal meets the requirements.

[0090] S302: Receive a reference signal of a measured TRP corresponding to a measured TRP identifier set sent by a network device.

[0091] In an embodiment of the present disclosure, the UE may receive a reference signal for measuring TRP sent by a network device and measure it.

[0092] S303: Determine a measurement result of the measurement quantity of the reference signal, and determine a measured TRP that meets the conditions as a recommended TRP based on the measurement result and the measurement parameters.

[0093] In an embodiment of the present disclosure, the UE receives configuration information of the network, including measurement quantities and measurement parameters. For the reference signal of the measurement 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 parameters indicated by the network device, thereby determining the measurement TRP that meets the conditions as the recommended TRP.

[0094] S304: Send the identifier of the recommended TRP or the recommended TRP reference signal to the network device.

[0095] In an embodiment of the present disclosure, the UE sends an identifier of a recommended TRP or a recommended TRP reference signal to a network device to assist the network device in determining a subsequently used sending TRP and / or receiving TRP.

[0096] In summary, according to the method proposed in the present disclosure, the UE can receive measurement configuration information sent by the network device, the measurement configuration information including the measurement sending / receiving point TRP identifier set, measurement quantity, and measurement parameters; receive the reference signal of the measurement TRP corresponding to the measurement TRP identifier set sent by the network device; determine the measurement result of the measurement quantity of the reference signal, and determine the measurement TRP that meets the conditions as the recommended TRP based on the measurement result and the measurement parameters; send the identifier of the recommended TRP or the recommended TRP reference signal to the network device, and the recommended TRP is used to assist the network device in determining the sending TRP and / or receiving TRP to be used subsequently. The solution proposed in the present disclosure solves the problem of collaborative transmission of multiple TRPs in distributed MIMO, by selecting appropriate partial TRPs from multiple TRP sets as service nodes to adapt to the CP of the terminal, and serving the terminal through multiple TRPs, thereby improving the signal reception quality of the terminal.

[0097] FIG4 is a flow chart of a communication method based on a distributed system according to an embodiment of the present disclosure. As shown in FIG3 , the method is executed by a UE. Based on the embodiment shown in FIG3 , the method may include the following steps.

[0098] S401: Receive measurement configuration information sent by a network device.

[0099] S402: Receive a reference signal of a measured TRP corresponding to a measured TRP identifier set sent by a network device.

[0100] 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 may be made to the description of the above embodiment, which will not be repeated here.

[0101] S403: Determine a measurement result of the measurement quantity of the reference signal, and determine a measured TRP that meets the conditions as a recommended TRP based on the measurement result and the measurement parameters.

[0102] Specifically, step S403 may include: determining a value of a measurement quantity of a reference signal as a measurement result; and determining a measurement TRP that meets the conditions as a recommended TRP according to the measurement result and the measurement parameters.

[0103] The UE receives measurement configuration information from the network device, which includes measurement quantity and measurement parameters. The UE can measure the received reference signal. For example, the measurement quantity indicated by the network device is RSRP, and the measurement parameters include 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. The UE can then determine the TRP that meets the conditions as the recommended TRP.

[0104] Among them, the UE can determine the measured TRP whose arrival time of the reference signal at the UE falls within the arrival time range as the alternative TRP.

[0105] For example, the measured TRP set indicated by the network device includes TRP 1, TRP 2, and TRP 3. The measured TRP can reach 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 uses the TRP whose arrival time falls within the arrival time range of 5s indicated by the network device as an alternative TRP. The arrival time of the reference signal includes a single-path arrival time or a multi-path arrival time. In other words, if the measured TRP corresponds to multiple paths, then when the multi-path arrival time of the TRP all falls within the arrival time range, the TRP can be determined as the recommended TRP.

[0106] 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 equipment only indicates the length of the arrival time range, without indicating the start and end time of the arrival time range. As for how the UE determines the start and end time of the arrival time range, there is no restriction and it depends on the specific application situation.

[0107] In an embodiment of the present disclosure, the UE may determine an alternative TRP whose measurement result is greater than or equal to the reference signal quality threshold as a recommended TRP. For example, in the above example of the present disclosure, the measurement quantity indicated by the network device is RSRP, and the reference signal quality threshold is -80dBm. When the UE determines that the RSRP value corresponding to the alternative TRP is -60dBm, the alternative TRP may be used as the recommended TRP.

[0108] S404: Receive a recommended TRP quantity threshold indicated by the network device.

[0109] In an embodiment of the present disclosure, the UE can receive a threshold number of recommended TRPs indicated by a network device, that is, the maximum reporting number. When the number of recommended TRPs determined by the UE is greater than the indicated threshold number, the UE can select and report a number of recommended TRPs that is less than or equal to the threshold number indicated by the network according to certain selection principles.

[0110] It is understandable that step S404 is an optional step, and the order in which the steps occur is not limited in this disclosure.

[0113] S406: Report the measurement result of the recommended TRP, where the measurement result is the value of the measurement quantity of the reference signal corresponding to the recommended TRP.

[0114] In an embodiment of the present disclosure, the UE may also report the measurement result of the recommended TRP to the network device.

[0115] It can be understood that step S406 is an optional step, and it can be performed simultaneously with step S405, or separately. The execution sequence thereof is not limited in the present disclosure.

[0116] In summary, according to the method proposed in this disclosure, a UE can receive measurement configuration information sent by a network device, the measurement configuration information including a set of measurement transmission / reception point TRP identifiers, measurement quantities, and measurement parameters; receive a reference signal of a measurement TRP corresponding to the set of measurement TRP identifiers sent by the network device; determine the measurement result of the reference signal measurement quantity, and determine a measurement TRP that meets the conditions as a recommended TRP based on the measurement result and measurement parameters; and send the recommended TRP or the identifier of the recommended TRP reference signal to the network device, where the recommended TRP is used to assist the network device in determining the subsequent transmission TRP and / or reception TRP. The solution proposed in this disclosure solves the problem of coordinated transmission of multiple TRPs in distributed MIMO. By selecting appropriate TRPs from a set of multiple TRPs as service nodes to adapt the CP of the terminal, multiple TRPs are used to serve the terminal, thereby improving the signal reception quality of the terminal. In this disclosure, the UE can also receive the maximum reporting quantity indicated by the network device, thereby further optimizing communication performance and resource allocation and reducing waste. In this disclosure, the UE can also report measurement results to the network device to assist the network device in making decisions based on the measurement results, further improving accuracy.
