Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a flow chart of a measurement method provided by an embodiment of the present invention, which is used for a network device. As shown in FIG. 1, the method includes the following steps:

It can be understood that after receiving the N reference signals sent by the network device, the relay device may forward them to the terminal device, and the terminal device receives the N reference signals and measures the N reference signals to obtain at least one target reference signal index. As an example, the relay device can amplify the N reference signals to enhance the signal, and send the amplified N reference signals to the terminal device to improve signal transmission performance. After the terminal device receives the amplified N reference signals, The target spatial filtering method or spatial transmission parameter can be determined based on the amplified N reference signals to measure the spatial filtering method or the spatial transmission parameter, which can improve the accuracy of the spatial filtering method or the spatial transmission parameter measurement. As an example, the above reference signal may be a CSI-RS (Channel State Information Reference Signal, channel state information reference signal) or the like.

It should be noted that the spatial filtering method (also referred to as the spatial transmission filtering method or the spatial receiving/transmitting filtering method, i.e. spatial domain transmission filter) and the spatial transmission parameter (also referred to as the spatial receiving/sending parameter, i.e. Spatial Tx/ Rx parameter) are all corresponding to beams. It can be understood that beams, spatial filtering methods and spatial transmission parameters have the same meaning, that is, the three can replace each other. Any one of the above-mentioned network devices and relay devices adopts a fixed spatial filtering method or a fixed spatial transmission parameter to transmit N reference signals, that is, the other adopts a variable spatial filtering method (N spatial filtering methods) or a variable spatial filtering method. The transmission parameters (N spatial transmission parameters) are used to transmit N reference signals, and after the terminal device receives the N reference signals and performs measurement to obtain at least one target reference signal index, it can report at least one target reference signal index to the network device, If both the network device and the relay device use fixed spatial filtering or spatial transmission parameters for reference signal transmission, the terminal device receives N reference signals and performs measurement to obtain at least one target reference signal index, at least one target reference signal The index is kept in the terminal device and is not reported to the network device. In this way, it can be determined whether to report the target reference signal index according to the spatial filtering method adopted by the network device and the relay device to transmit the reference signal or the spatial transmission parameters, which can improve the reference signal index. Reporting flexibility. As an example, for a network device and a relay device, reference signal transmission may be understood as reference signal transmission, and for a terminal device, reference signal transmission may be understood as reference signal reception.

The terminal equipment measures the N reference signals, and at least one target reference signal index It can be used for the terminal device to report to the network device, that is, the terminal device can report at least one target reference signal index; or, both the network device and the relay device can use fixed spatial filtering or fixed spatial transmission parameters to transmit N reference signals , the terminal device measures the N reference signals, and may not report at least one target reference signal index to the network device. In this way, through the relay device cooperating with the network device, one of the two uses a fixed spatial filtering method or a fixed spatial transmission parameter to transmit N reference signals, so that the terminal device measures the N reference signals and reports at least one of the measured signals. Target reference signal index; or both use a fixed spatial filtering method or a fixed spatial transmission parameter to transmit N reference signals, so that the terminal device measures N reference signals, and does not report at least one target reference signal index obtained from the measurement , so that the reference signal measurement effect can be improved.

In this embodiment, the network device instructs the relay device to use a fixed spatial transmission filtering method or a fixed spatial transmission parameter to transmit a reference signal to the terminal device or to use N different spatial transmission filtering methods or N different spatial transmission parameters ( Changed spatial transmission filtering mode or spatial transmission parameter) to transmit reference signals to the terminal equipment, and the network equipment sends the second signaling to the terminal equipment through the relay equipment, and the second indication information instructs the terminal equipment to adopt fixed spatial reception filtering The method or the spatial reception parameter is used to receive the reference signal, or N different spatial reception filtering methods or N different spatial reception parameters (variable spatial reception filtering methods or spatial reception parameters) are used for reference signal reception. In this way, the network device sends the first signaling and the second signaling to instruct the relay device to transmit the reference signal and to instruct the terminal device to receive the reference signal, so that any one of the network device and the relay device adopts a fixed The spatial filtering method or fixed spatial transmission parameters for reference signal transmission, the terminal equipment adopts fixed spatial filtering method or fixed spatial transmission parameters for reference signal transmission, or both network equipment and relay equipment adopt fixed spatial filtering method or fixed spatial transmission parameters For reference signal transmission, the terminal device uses N spatial filtering methods or N spatial transmission parameters to perform reference signal transmission.

ResourceSet, according to the first repetition field therein, it can be known whether the spatial transmission filtering mode or the spatial transmission parameters adopted by the network device for sending the N reference signals are repetitive or non-repetitive. If the network device sends the second signaling to the terminal device through the relay device, and the second signaling also includes NZP-CSI-RS-ResourceSet and the second repeated field, it can be understood that the network device configures NZP-CSI-RS for the terminal device -ResourceSe, which can be the same as the NZP-CSI-RS-ResourceSet configured by the above network device for the relay device. After receiving the second signaling, the terminal device can specify the NZP-CSI-RS used to send the reference signal according to the second signaling -ResourceSet, according to the second repetition field therein, it can be known whether the spatial transmission filtering mode or the spatial transmission parameters adopted by the network device or the relay device for sending the N reference signals are repetitive or non-repetitive. It should be noted that if the first repetition field is turned on, the first repetition field is used to indicate that the spatial transmission filtering method or spatial transmission parameter used to send the N reference signals is repeated; if it is off, the first repetition field is used Since it is indicated that the spatial transmission filtering mode or the spatial transmission parameter used for sending the N reference signals is non-repetitive, it can be understood that the spatial transmission filtering mode or the spatial transmission parameter is changed. If the second repetition field is turned on, the second repetition field is used to indicate that the spatial transmission filtering method or spatial transmission parameter used for sending N reference signals is repeated; if it is turned off, the second repetition field is used to indicate that N reference signals are sent The spatial transmission filtering method or spatial transmission parameter adopted by the reference signal is non-repetitive, that is, the adopted spatial transmission filtering method or spatial transmission parameter is changed.

The network device sends N reference signals to the relay device using a fixed spatial transmission filtering method or fixed spatial transmission parameters. For example, the network device can use a fixed first spatial transmission filtering method or a fixed first spatial transmission parameter to send N reference signals to the relay device. N reference signals, it can be understood that the spatial transmission filtering method or spatial transmission parameters used by the network device to send N reference signals to the relay device are repeated, the first repetition field is open, and the relay device amplifies the N reference signals Forwarding to the terminal device, since the first indication information instructs the relay device to use N spatial transmission filtering methods or spatial transmission parameters to transmit reference signals to the terminal device, the relay device receives N reference signals, and uses N different The spatial transmission filtering methods or spatial transmission parameters are sent to the terminal equipment. The N reference signals correspond to the N spatial transmission filtering methods or N spatial transmission parameters one by one. Each reference signal adopts a corresponding spatial transmission filtering method or In the transmission of space transmission parameters, the terminal equipment uses a fixed space reception filtering method or space reception parameters to receive the reference signal sent by the relay equipment.

It can be understood that the spatial transmission filtering method or spatial transmission parameter used by the network device to send the N reference signals to the relay device is repeated. The relay device amplifies the N reference signals and forwards them to the terminal device. Since the first indication information instructs the relay device to use a fixed spatial transmission filtering method or fixed spatial transmission parameters to transmit reference signals to the terminal device, the relay device receives the N reference signals. After the signal is amplified, it is sent to the terminal device using a fixed spatial transmission filtering method or spatial transmission parameters. For example, the relay device can use a fixed second spatial transmission filtering method or a fixed second spatial transmission parameter to send the amplified signal to the terminal device. For the last N reference signals, the first spatial transmission filtering method or the second spatial transmission filtering method may be the same or different, and the first spatial transmission parameter may be the same as or different from the second spatial transmission parameter. The second repetition field is ON. It can be understood that the spatial transmission filtering mode or the spatial transmission parameters used by the relay device to transmit the amplified N reference signals to the terminal device are repeated. The terminal device uses N different spatial reception filtering methods or spatial reception parameters to receive the amplified N reference signals sent by the relay device, and the N reference signals correspond to the N spatial reception filtering methods one by one, or N reference signals There is a one-to-one correspondence between the signal and the N space receiving parameters.

The terminal device can perform measurement based on the received amplified N reference signals, and determine at least one target reference signal index, that is, determine an appropriate spatial reception filtering method or spatial reception parameter, which can improve the reference signal measurement effect.

In one embodiment, the second signaling further includes third indication information, where the third indication information is used to instruct the terminal device to report at least one target reference signal index or not to report at least one target reference signal index.

That is, in this implementation, the terminal device measures N reference signals to determine at least one target reference signal index, and can determine whether to report at least one target reference signal index according to the third indication information in the second signaling, that is, the terminal device Whether to report at least one target reference signal index is determined according to the third indication information, so as to improve the flexibility of reporting the at least one target reference signal index.

The process of the above method will be described in detail below with a specific embodiment. The network device is gNB (5G base station), the relay device is Smart repeater (intelligent relay device), and the terminal device is UE (user equipment) as an example. The spatial filtering manner, the spatial transmission parameter, and the beam can be substituted for each other. In this embodiment, the beam is used as an example for illustration.

For the Smart repeater in the FR2 frequency band, first consider the downlink beam management. When forwarding the downlink signal, it needs to know which receiving beam to use to receive the downlink signal sent by the gNB, and on the other hand, it needs to decide which sending beam to use for the receiving The received downlink signal is forwarded. For the former, if the Smart repeater has the function of an ordinary UE, it can reuse the existing UE downlink beam management process to determine the receiving beam for receiving gNB downlink signals; for the latter, the Smart repeater needs to cooperate with the base station and UE to perform beam measurement and reporting, so that the gNB can provide the Smart Repeater with indication information of space-related information/beam-related information to instruct the Smart Repeater which transmit beam to use to forward the received downlink signal, etc.

When there is no Smart repeater, when gNB communicates with an ordinary UE, the base station can know which transmission beam of the base station to use for downlink has the best transmission performance through the existing beam measurement and reporting mechanism. The existing beam measurement and reporting mechanism includes Transmit Beam Measurement and Receive Beam Measurement:

Transmit beam measurement: The base station changes the transmit beam, and the UE fixes the receive beam. The base station configures N reference signals, corresponding to N candidate transmission beams, and the base station notifies the UE that there are N reference signals corresponding to the measurement of different transmission beams; the UE uses a fixed receiving beam to receive and measure all N reference signals, and selects the most suitable transmission beam report to the base station.

Receive beam measurement: The UE changes the receive beam and assumes that the base station fixes the transmit beam. The base station uses the same beam to send N reference signals, and instructs the UE to determine the best receiving beam by changing the receiving beam measurement method. The best receiving beam determined by the UE may not be reported to the base station, but stored in the UE.

However, as shown in Figure 4, when there is a Smart repeater, when the gNB communicates with an ordinary UE, even if the base station uses a fixed beam, when the Smart repeater uses a different beam for downlink signal forwarding, the received signal quality of the UE is not good. the same. Therefore, it is necessary to enhance the existing beam measurement and reporting mechanism to more effectively support scenarios with Smart repeaters and improve the beam measurement effect.

In one embodiment, the gNB fixes the transmission beam and sends N reference signals with the same transmission beam; the base station instructs the Smart repeater to use N different transmission beams to amplify and forward the N reference signals (for example, changing the beam by polling ), as shown in Figure 5. The UE uses a fixed receiving beam to receive and measure all N reference signals, selects the most suitable sending beam (corresponding to at least one target reference signal index) and reports it to the base station.

In this embodiment, for the Smart repeater, the base station configures an NZP-CSI-RS-ResourceSet for beam management for the Smart repeater. For example, the NZP-CSI can be configured for the Smart repeater through a high-level signaling (corresponding to the first signaling). -RS-ResourceSet, the repetition field in this high-level signaling can be set to on (open), but the Smart repeater does not need to determine and report the CRI, and the Smart repeater only needs to use N different transmission beams to amplify the N reference signals Forward. For the UE, the base station configures a NZP-CSI-RS-ResourceSet for beam management (the same as that configured for the Smart repeater) for the UE, and configures the NZP-CSI-RS-ResourceSet for the UE through a high-level signaling (corresponding to the second signaling). In RS-ResourceSet, the repetition field in this high-level signaling can be set to off (closed), and the UE needs to determine and report the CRI. Or, for the UE, the base station configures a NZP-CSI-RS-ResourceSet for beam management (the same as that configured for the Smart repeater) for the UE, and the repetition field in its high-level signaling can be set to on, but the UE needs to determine and Report to CRI.

In another embodiment, the base station changes the transmission beam, and the base station configures N reference signals corresponding to N different transmission beams. The Smart repeater uses a fixed transmission beam to amplify and forward the N reference signals; the UE uses a fixed reception beam to receive and measure For all the N reference signals, the most suitable transmission beam is selected and reported to the base station, as shown in FIG. 6 .

For the Smart repeater, the base station configures an NZP-CSI-RS-ResourceSet for beam management for the Smart repeater, and the repetition field in the high-level signaling can be set to off, but the Smart repeater does not need to determine and report the CRI, and the Smart repeater only needs to The N reference signals are amplified and forwarded by using a fixed sending beam. For the UE, the base station configures a NZP-CSI-RS-ResourceSet for beam management (the same as that configured for the Smartrepeater) for the UE, and the repetition field in the high-layer signaling can be set to off, and the UE needs to determine and report the CRI, for example , the UE can report the CRI to the Smart repeater, and forward it to the base station through the Smart repeater.

In yet another embodiment, the base station fixes the sending beam and sends L reference signals with the same beam; the base station instructs the Smart repeater to use the fixed beam to amplify and forward the L reference signals; the base station instructs the UE to determine by changing the receiving beam measurement For the best receiving beam, the best receiving beam determined by the UE does not need to be reported to the network, but stored in the UE.

For the Smart repeater, the base station configures a NZP-CSI-RS-ResourceSet for beam management for the Smart repeater, and the repetition field in the high-level signaling can be set to on. The Smart repeater does not need to determine and report the CRI, but the base station needs to instruct the Smart repeater The repeater uses a fixed beam to amplify and forward the N reference signals. For the UE, the base station configures a NZP-CSI-RS-ResourceSet for beam management (the same as that configured for the Smartrepeater) for the UE. The repetition field in the high-layer signaling can be set to on, and the UE uses a changed receiving beam to measure To determine the best receiving beam, it is not necessary to report CRI.

In the beam measurement and reporting methods of the above embodiments, the standard needs to at least enhance the support for the following functions:

Standard enhancement 1: The base station configures NZP-CSI-RS-ResourceSet for smart repeat, and when the repetition field is set to off, it does not need to report CRI. Since the existing standard also supports the base station to configure NZP-CSI-RS-ResourceSet for the terminal, and when the repetition field is set to off, the UE shall determine the CRI according to the supported CRI value set. Therefore, one method is to add an indication signaling from the base station to the UE in the standard, which is used to indicate whether the UE needs to report the CRI when the NZP-CSI-RS-ResourceSet is configured and the repetition field is set to off. For example, an indication signaling (criReportDisabled) is introduced in NZP-CSI-RS-ResourceSet or elsewhere, and the value is ENUMERATED{true}. Another method is that when the base station configures NZP-CSI-RS-ResourceSet for the Smart repeater, the rule is that when the repetition field is set to off, the CRI is not reported. However, NZP-CSI-RS-ResourceSet is configured for common UEs, and the repetition field is set to off.

Standard enhancement 2: When the base station configures NZP-CSI-RS-ResourceSet for the Smart Repeater and sets the repetition field to on, the base station needs to indicate whether the Smart Repeater uses a fixed transmission beam for amplification and forwarding of reference signals or uses a changing transmission beam for reference Signal amplification and forwarding.

Through the present invention, more intelligent relay data transmission can be realized, and FR2 (millimeter wave) can be effectively supported.
