Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a signal configuration method, network equipment, user equipment and intermediate node equipment of a communication system. Background Art

[0002] The intermediate node is based on controlling the propagation of electromagnetic waves in the communication channel to improve the performance of the communication system. For example, the Reconfigurable Intelligent Surface (RIS) is a metasurface composed of a large number of tiny elements that diffusely reflect the incident signal in a controllable manner. In the prior art, the beam direction of the RIS can be determined by measuring the quality of the reference signal (for example, the synchronization signal block SSB and the channel state information reference signal CSI-RS). Depending on the different configuration situations, the base station can only configure a maximum of 192 CSI-RS resources for the terminal. Due to the limited number of CSI-RS resources, when the number of RIS panels is large, it is impossible to allocate a reference signal for each beam direction of the RIS. Therefore, when the wireless network introduces RIS, how to design a reasonable reference signal to calculate the beam direction of the RIS is a problem that needs to be solved.

The intermediate node device 13 includes but is not limited to an intelligent super surface, and may be a network node having similar functions thereto. In the present application, the service signal sent by the network device 11 can be transmitted to the user equipment 12 via the intermediate node device 13 .

[0072] As described in the background technology, in the prior art, due to the limited number of CSI-RS resources, when the number of RIS panels is large, it is impossible to allocate reference signals for each beam direction of RIS. Therefore, when RIS is introduced into the wireless network, how to design a reasonable reference signal to calculate the beam direction of RIS is a problem that needs to be solved. In order to solve at least one of the above problems, the embodiments of the present application provide a signal configuration method, a network device, a user device, and an intermediate node device of a communication system.

[0073] Please refer to Figure 2, an embodiment of the present application provides a signal configuration method for a communication system, wherein the communication system includes a network device, an intermediate node device, and a user device; a service signal sent by the network device is transmitted to the user device via the intermediate node device, and the method is used for the network device, including:

[0074] Step 21: Send a first reference signal to the user equipment;

[0075] Here, the network device of the present application may send a first reference signal to the user equipment in different directions by means of beam scanning. One beam scan may correspond to a direction of receiving beam scanning. In one possible implementation, the network device includes but is not limited to at least one of the following: an access network device (such as a base station); a core network device. The core network device may send a first reference signal to the user equipment through the access network device.

[0076] Correspondingly, the user equipment adopts the receiving beam scanning method to achieve better coverage of the receiving angle. For example, the antenna of the user equipment in the A frequency band adopts 8 receiving beams to cover a range of 120°, that is, the user equipment generates 8 beams through beamforming, each beam points to a beam direction, and achieves 120° beam coverage. Among them, each receiving beam corresponds to a receiving beam direction.

[0077] Step 22: Receive a reporting result of the first reference signal sent by the user equipment. Here, the reporting result is a result reported by the user equipment for beam training based on the beam measurement reporting configuration of the first reference signal.

[0078] In the present application, the first reference signal can be understood as a downlink reference signal, which includes a demodulation reference signal (De Modulation Reference Signal, DMRS) and / or a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS) of a downlink service channel, etc. The user equipment performs measurement and reporting based on the first reference signal configuration information sent by the network device. For example, the user equipment performs corresponding beam training according to the first reference signal configuration information, and reports the result of the beam training to the network device; the network device receives the reporting result of the first reference signal; according to the reporting result, it can be determined that when the user equipment processes the current service, the channel quality of the reference signal transmitted on which antenna port is better. Here, the channel quality can be determined according to the transmission channel quality, the transmission signal rate, etc. This application only needs to know that when transmitting the current service, the reporting result is used to indicate which antenna port has the best reference signal channel quality.

[0079] Step 23: Send first configuration information to the user equipment; the first configuration information is used to configure a second reference signal associated with a reporting result of the first reference signal.

[0080] For example, when the network device and the user equipment interact, the user equipment can use CSI-RS 0-3 to transmit information, and CSI-RS 0 to 3 respectively represent the CSI-RS reference signals transmitted on antenna ports 0 to 3. Before receiving the reporting result, the network device does not know in which beam direction the user equipment is located that the channel quality is the best. Here, the reporting result fed back by the user equipment can represent the channel quality. If the reporting result indicates that the channel quality in the beam direction of CSI-RS 3 is the best, the network device associates CSI-RS 3 with the second reference signal based on the reporting result, and there is no need to consider the beam direction of CSI-RS 0-2 where the user equipment is located.

[0081] Step 24: receiving the second reference signal sent by the user equipment;

[0082] Step 25: Send first control information to the intermediate node device according to the measurement result of the second reference signal.

[0083] It should be noted that the first control information of the present application refers to the control information transmitted by the control link between the network device and the intermediate node. The first control information is used to control the intermediate node device and set the beam direction of the intermediate node device.

[0084] Here, the measurement result of the second reference signal includes the amplitude measurement result of the second reference signal and the phase measurement result of the second reference signal. In the present application, according to the measurement result, the network device can determine the first control information according to the preconfigured coding calculation formula. For example, the first control information includes the reflection beam direction of the intermediate node. For the network device, the first control information is an unpredictable precoding matrix, which can only be determined with the measurement result of the second reference signal.

[0085] For example, the network device calculates first control information, such as precoding, based on the measurement result of the second reference signal, and sends corresponding phase / precoding / codeword indication to the intermediate node device to indicate the reflection beam direction of the intermediate node device.

[0086] The second reference signal in the embodiment of the present application can be an uplink reference signal sent by the user equipment. By sending the first configuration information to the user equipment, the second reference signal associated with the reporting result of the first reference signal can be determined. Correspondingly, the user equipment can determine the second reference signal according to the first configuration information, and send the second reference signal to the network device. The network device of the present application associates the downlink reference signal with the uplink reference information, and uses the two signals to jointly select the control information of the intermediate node device, that is, to determine the first control information of the intermediate node device, and realizes the calculation of the beam direction of each intermediate node according to the reference signal. Under the condition that the number of configurable reference signals is limited, each reference signal of the midpoint node device is configured, and the number of midpoint node devices is no longer limited, thereby improving the data transmission quality and communication efficiency.

[0087] Optionally, before step 21, the method further includes:

[0088] Sending second configuration information to the user equipment; the second configuration information includes reporting configuration information of the first reference signal and related information of the first reference signal; the related information includes at least one of the following: subcarrier spacing information of the first reference signal, frequency domain position information of the first reference signal, and time domain position information of the first reference signal.

[0089] Here, the reported configuration information includes: (1) measurement type; the measurement name or measurement ID can be used.

[0090] (2) A matching condition corresponding to the measurement type; each measurement type has a corresponding matching condition, that is, when a terminal satisfies a certain condition, it means that the measurement type is satisfied. The matching condition may include a logical "and" connection relationship of several conditions, and the matching condition may indicate a range of measurement data that needs to be collected.

[0091] (3) The matching condition ID: used to identify the matching condition. Different matching conditions have different IDs.

[0092] In an embodiment of the present application, before receiving the reporting result of the first reference signal sent by the user equipment, second configuration information can be sent to the user equipment, that is, the reporting configuration information of the first reference signal and the related information of the first reference signal are sent to the user equipment; the related information of the first reference signal is sent to inform the user equipment of the sending position, frequency, time domain and other information; the reporting configuration information of the first reference signal is sent to tell the user equipment the configuration information for measurement reporting, so that the user equipment can perform measurement reporting.

[0093] For example, in the above step 21, the first reference signal sent to the user equipment may be a reference signal with a beam management function, including but not limited to a channel state information reference signal CSI-RS, etc., where CSI-RS 0-3 may be sent to the user equipment; wherein CSI-RS 0 to 3 respectively represent CSI-RS reference signals transmitted on antenna ports 0 to 3. Correspondingly, after receiving the above second configuration information, the user equipment performs measurement reporting, and the user equipment determines that the channel quality is good in the beam direction of CSI-RS 3, and the user may choose to report the information of CSI-RS 3, and the information of CSI-RS 3 is the reporting result of the first reference signal sent by the user equipment.

[0094] Optionally, after step 21, the method further includes:

[0095] Sending second control information to the intermediate node device; the second control information carries phase indication information; the phase indication information is used to instruct the intermediate node device to maintain the reflection phase corresponding to the reporting result of the first reference signal. Here, the second control information is used to indicate the reflection phase of the intermediate node.

[0096] When the present application sends the first reference signal to the user equipment, it has sent an indication of the corresponding reflection phase to the intermediate node device in the corresponding time-frequency resource. At this time, the intermediate node device uses the beam corresponding to the reflection phase to forward information. After the network device receives the reporting result of the first reference signal, it can determine at which reflection phase the intermediate node device is located where the channel quality of the user equipment is better, thereby determining the second control information, and sending the second control information to the intermediate node device to instruct the intermediate node device to maintain the reflection phase determined by the reporting result. For example, when the network device sends the first reference signal, it can indicate that the corresponding beam is CSI-RS2 or CSI-RS 3, etc., and the second control information determined by the reporting result is CSI-RS 3, then the intermediate node device is instructed to maintain the reflection phase of CSI-RS 3 through the second control information.

[0097] Optionally, in the first configuration information, an uplink channel acquisition function corresponding to the second reference signal is associated with a beam management function corresponding to a reporting result of the first reference signal;

[0098] The transmission mode of the second reference signal includes a codebook transmission mode or a non-codebook transmission mode.

[0099] In the embodiment of the present application, the functions of the second reference signal include but are not limited to beam management (Beam-management) function, uplink channel acquisition function corresponding to the transmission mode based on the second reference signal, downlink channel information acquisition function based on sounding reference signal (Sounding Reference Signal, SRS) antenna switching, etc. The functions corresponding to the reporting result of the first reference signal include but are not limited to the acquisition of channel state information (CSI-RS for CSIcomputation) function, time-frequency tracking (CSI-RS for tracking) function, beam management (CSI-RS for L1-RSRP computation) function, mobility management (CSI-RS for mobility) function, rate matching (ZP-CSI-RS) function and interference measurement (CSI-IM) function, etc. In the first configuration information of the present application, it is only necessary to associate the uplink channel acquisition function corresponding to the second reference signal with the beam management function corresponding to the reporting result of the first reference signal, that is, to associate the uplink channel acquisition function corresponding to the codebook transmission mode or the non-codebook transmission mode with the beam management function corresponding to the reporting result of the first reference signal. On the one hand, a processing method for determining the control information of the intermediate node device by the codebook transmission mode is specified. On the other hand, in the non-codebook transmission mode, there is no need to associate the non-codebook with the channel state information acquisition function, which improves the processing time for determining the control information of the intermediate node device and also improves the accuracy of calculating the control information.

[0100] Optionally, the first control information includes at least one of the following:

[0101] Phase information;

[0102] Precoding information;

[0103] Codeword information.

[0104] In an embodiment of the present application, at least one of phase information, precoding information and codeword information is sent to an intermediate node device, which can be used to indicate the phase or beam direction corresponding to the intermediate node, accurately design the corresponding beam direction (phase or codebook) for each reference signal of the intermediate node device, and improve the data transmission quality according to the determined transmission direction.

[0105] Optionally, after step 24, the method further includes:

[0106] Sending scheduling permission information to the user equipment, where the scheduling permission information is used to indicate permission for uplink or downlink resource transmission between the network device and the user equipment.

[0107] In an embodiment of the present application, after sending the first control information to the intermediate node device, access permission information is sent to the user device. The access permission information ensures the data transmission quality between the network device and the user device when the number of intermediate node devices is too large. The scheduling permission information can be an uplink scheduling permission or a downlink scheduling permission. The uplink or downlink resource transmission between the network device and the user device is allowed through the access permission information.

[0108] In summary, the present application proposes that the base station sends a first reference signal, and the user sends a second reference signal, and the second reference signal is associated with the reporting result of the first reference signal, and the association relationship is: the uplink channel acquisition function of the second reference signal is associated with the beam management function of the reporting result of the first reference signal; the present application also proposes to calculate the beam direction / phase / precoding / codeword indication of the intermediate node device through two reference signals; the present application also proposes that the base station sends an indication to the intermediate node device to maintain the phase, that is, the base station sends a second control information to the intermediate node device, and the phase in the second control information is associated with the resource corresponding to the reporting result of the first reference signal, which can improve the quality of data transmission.

[0109] Please refer to Figure 3 , an embodiment of the present application provides a signal configuration method for a communication system, wherein the communication system includes a network device, an intermediate node device, and a user device; a service signal sent by the network device is transmitted to the user device via the intermediate node device, and the method is used for the user device, including:

[0114] In an embodiment of the present application, a first reference signal sent by a network device is received, and the first reference signal can be selected as a downlink reference signal with a beam management function; the present application measures and reports the first reference signal, and sends the reporting result of the first reference signal to the network device; the first configuration information sent by the network device is received, and according to the first configuration information, a second reference signal associated with the reporting result of the first reference signal is determined, and the second reference signal is sent to the network device, wherein the corresponding uplink channel acquisition function of the second reference signal is associated with the beam management function corresponding to the reporting result of the first reference signal; the transmission mode of the second reference signal includes a codebook transmission mode or a non-codebook transmission mode. Under the condition that the number of configurable signals is limited, the present application can jointly select the control information of the intermediate node device by using two signals, and the control information such as phase, precoding, codeword, etc. can improve the signal quality of the intermediate node device when forwarding the network device to transmit the current service.

[0115] It should be noted that the functions of the second reference signal include but are not limited to beam management (Beam-management) function, uplink channel acquisition function corresponding to the transmission mode based on the second reference signal, downlink channel information acquisition function based on sounding reference signal (Sounding Reference Signal, SRS) antenna switching, etc. The functions corresponding to the reporting results of the first reference signal include but are not limited to obtaining channel state information (CSI-RS for CSI computation) function, time-frequency tracking (CSI-RS for tracking) function, beam management (CSI-RS for L1-RSRPcomputation) function, mobility management (CSI-RS for mobility) function, rate matching (ZP-CSI-RS) function and interference measurement (CSI-IM) function, etc. In the first configuration information of the present application, it is only necessary to associate the uplink channel acquisition function corresponding to the second reference signal with the beam management function corresponding to the reporting result of the first reference signal, that is, to associate the uplink channel acquisition function corresponding to the codebook transmission mode or the non-codebook transmission mode with the beam management function corresponding to the reporting result of the first reference signal. On the one hand, a processing method for determining the control information of the intermediate node device by the codebook transmission mode is specified. On the other hand, in the non-codebook transmission mode, there is no need to associate the non-codebook with the channel state information acquisition function, which improves the processing time for determining the control information of the intermediate node device and also improves the accuracy of calculating the control information.

[0116] Optionally, before step 31, the method further includes:

[0117] receiving second configuration information sent by the network device; the second configuration information includes reporting configuration information of the first reference signal and related information of the first reference signal; the related information includes at least one of the following: subcarrier spacing information of the first reference signal, frequency domain position information of the first reference signal, and time domain position information of the first reference signal;

[0120] (2) A matching condition corresponding to the measurement type; each measurement type has a corresponding matching condition, that is, when a terminal satisfies a certain condition, it means that the measurement type is satisfied. The matching condition may include a logical "and" connection relationship of several conditions, and the matching condition may indicate a range of measurement data that needs to be collected.

[0121] (3) The matching condition ID: used to identify the matching condition. Different matching conditions have different IDs.

[0122] In the embodiment of the present application, the second configuration information sent by the receiving network device can be learned, the reporting configuration information of the first reference signal sent by the user equipment and the related information of the first reference signal; by way of example, the sending position, frequency, time domain, reporting configuration information and other information of the user equipment for measurement reporting can be learned, so that it can be determined which specific reference signal the user equipment reports, the reporting method, etc. For example, the first reference signal sent by the receiving network device includes but is not limited to the channel state information reference signal CSI-RS, etc., by way of example, here is CSI-RS 0-3, CSI-RS 0 to 3 respectively represent the CSI-RS reference signals transmitted on antenna ports 0 to 3, and the measurement and reporting is performed according to the second configuration information sent by the receiving network device, and it is determined that the reporting quality of the user equipment at CSI-RS 3 is the best, then the reporting result of the first reference signal is CSI-RS 3 and the related information of CSI-RS 3, and the reporting result is sent to the network device.

[0123] To summarize, the present application can determine the first reference signal based on the configuration information sent by the network device, and send the reporting result of the first reference signal to the network device; it can also determine the second reference signal associated with the first reference signal based on the first configuration information sent by the network device, and send the second reference signal to the network device, which can facilitate the subsequent determination of the control information of the intermediate node device.

[0124] Please refer to Figure 4 , an embodiment of the present application provides a signal configuration method for a communication system, wherein the communication system includes a network device, an intermediate node device, and a user device; a service signal sent by the network device is transmitted to the user device via the intermediate node device, and the method is used for the intermediate node device, including:

[0125] Step 41: receiving first control information sent by the network device; the first control information is determined by the network device measuring a second reference signal sent by the user equipment, the second reference signal is associated with a reporting result of a first reference signal reported by the user equipment to the network device, and the reporting result of the first reference signal is a measurement result of the first reference signal sent by the user equipment to the network device;

[0126] Step 42: Adjust the operating state of the intermediate node device according to the first control information.

[0127] In an embodiment of the present application, a first control information sent by a network device is received, and an operating state of an intermediate node device is adjusted. The operating state includes the state of a beam direction and / or phase information corresponding to the intermediate node. The present application adjusts the reflection phase of the intermediate node device according to the first control information, and adjusts it to the phase and / or beam direction corresponding to the first control information, thereby adjusting the operating state of the intermediate node device, achieving accurate positioning of each reference signal, and improving the quality of information transmission between subsequent network devices and user devices.

[0128] Optionally, the first control information includes at least one of the following:

[0129] Phase information;

[0130] Precoding information;

[0131] Codeword information.

[0132] In an embodiment of the present application, the intermediate node device receives the first control information, and may receive at least one of the phase information, precoding information, and codeword information, which is used to indicate the phase or beam direction corresponding to the intermediate node device, and accurately designs the corresponding beam direction (phase or codebook) for each reference signal of the intermediate node device, thereby improving the data transmission quality according to the determined transmission direction.

[0133] Optionally, before step 41, the method further includes:

[0134] receiving second control information sent by the network device; the second control information carries phase indication information; the phase indication information is used to instruct the intermediate node device to maintain the reflection phase corresponding to the reporting result of the first reference signal;

[0135] The reporting result of the first reference signal is a measurement result of the first reference signal sent by the user equipment to the network equipment. Here, the reporting result is a result reported by the user equipment for beam training based on the beam measurement reporting configuration of the first reference signal. The second control information is used to indicate the reflection phase of the intermediate node.

[0136] In an embodiment of the present application, when the network device sends the first reference signal to the user device, it has already sent an indication of the corresponding reflection phase to the intermediate node device in the corresponding time-frequency resource. At this time, the intermediate node device uses the beam corresponding to the reflection phase to forward information. After the network device receives the reporting result of the first reference signal, it can determine at which reflection phase the intermediate node device is located where the channel quality of the user device is better, thereby determining the second control information. The intermediate node device of the present application receives the second control information, and determines the reflection phase that the indicated intermediate node device needs to maintain through the phase indication information in the second control information. Here, the reflection phase that needs to be maintained is determined according to the reporting result. After receiving the second control information sent by the network device, the present application determines that the phase or beam direction corresponding to the reporting result of the first reference signal remains unchanged. The present application can improve the time for adjusting the second control information according to the first control information, thereby improving the positioning efficiency of the intermediate node device.

[0137] For example, the first reference signal sent by the network device to the user equipment is CSI-RS 0-3, and CSI-RS 0 to 3 respectively represent the CSI-RS reference signals transmitted on antenna ports 0 to 3. At this time, the phase information of the resources corresponding to CSI-RS 0-3 has been sent to the intermediate node device, and the reporting result of the first reference signal received by the network device is CSI-RS 3. Since the intermediate node device previously has the phase information of CSI-RS 3, after receiving the second control information sent by the network device, it only needs to keep the phase or beam direction corresponding to CSI-RS 3 unchanged.

[0138] Optionally, the uplink channel acquisition function corresponding to the second reference signal is associated with the beam management function corresponding to the reporting result of the first reference signal; wherein the transmission mode of the second reference signal includes a codebook transmission mode or a non-codebook transmission mode.

[0139] In an embodiment of the present application, the first control information is determined by the network device after processing the second reference signal sent by the user equipment, and the uplink channel acquisition function corresponding to the second reference signal is associated with the beam management function corresponding to the reporting result of the first reference signal sent by the user equipment to the network device. On the one hand, a processing method for determining the control information of the intermediate node device in the codebook transmission mode is specified. On the other hand, in the non-codebook transmission mode, there is no need to associate the non-codebook with the channel state information acquisition function, which improves the processing time for determining the control information of the intermediate node device and also improves the accuracy of calculating the control information.

[0140] It should be noted that the first reference signal can be any uplink reference signal as long as it has a beam management function, and the specific type of the first reference signal is not limited here.

[0141] Under the condition that the number of configurable reference signals is limited, the present application proposes to use two reference signals to jointly select the beam direction of the intermediate node device, and the corresponding beam direction or phase can be designed for each reference information, thereby improving the data transmission quality.

[0142] like FIG. 5A to FIG. 5C As shown, the present application also provides a specific embodiment of a communication system signal configuration method, which is applied to a communication system, wherein the communication system includes a network device, an intermediate node device and a user device; the service signal sent by the network device is transmitted to the user device via the intermediate node device, wherein the network device is exemplified by a base station (BS) 51, the user device is exemplified by a UE 52, and the intermediate node device is exemplified by a RIS 53, including:

[0143] Step 1: The base station 51 sends a first reference signal configuration and a reporting configuration to the UE 52 .

[0144] Step 2: The base station 51 sends the first reference signal (CSI-RS 0-3). It is assumed that the base station 51 has indicated the beam to the RIS in the corresponding time-frequency resources, and the RIS forwards the CSI-RS with a wide beam. CSI-RS2 and CSI-RS 3 correspond to the wide beam of the RIS.

[0145] Step 3: UE 52 is located in the beam direction of CSI-RS 3, the channel quality is good, and the UE reports the information of CSI-RS 3.

[0146] Step 4: The base station 51 instructs the RIS 53 to maintain the phase on the time-frequency resource where the UE 52 sends the signal (corresponding to the CSI-RS3 direction).

[0147] Step 5: The base station 51 sends a second reference signal configuration associated with the first reference signal resource.

[0148] Step 6: UE 52 sends a second reference signal (SRS 0 - SRS 2 ).

[0149] Step 7: The base station receives the second reference signal, calculates the precoding, and determines the first control information of the intermediate node device, that is, determines that the control information channel quality corresponding to SRS1 used by RIS 53 is the best, and then sends the corresponding phase / precoding / codeword indication to RIS 53.

[0150] Step 8: The base station 51 sends uplink or downlink scheduling permission information and then performs data transmission.

[0151] The solution of the present application proposes to use two reference signals to jointly select the RIS beam direction under the condition that the number of configurable reference signals is limited, provides the phase positioning direction of the intermediate node device, and improves the channel transmission quality.

[0152] In another embodiment, in the relevant standards: for the non-codebook uplink transmission scheme, the UE obtains the candidate uplink precoding matrix according to the downlink reference signal. In order to enable the UE to calculate the candidate precoding matrix more accurately, the base station associates a non-zero power (NZP) CSI-RS for the SRS resource set of non-codebook transmission. The UE obtains the precoding of the SRS according to the NZP CSI-RS resource. In the relevant standards, the "csi-RS" and "associatedCSI-RS" in the resource type (resourceType) field of the SRS resource set, that is, the SRS of the relevant standards is associated with the channel information acquisition function of the CSI-RS based on the non-codebook uplink channel information acquisition; and the base station of the present application sends a second reference signal configuration, which is associated with the first reference signal resource; the uplink channel acquisition function of the second reference signal of the present application is directly associated with the beam management function of the first reference signal, which shortens the matching time and improves the positioning accuracy of the second reference signal.
