Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a method and apparatus for information reporting. Background Art

[0002] In a high-frequency communication system, in order to overcome path loss, the network and the terminal usually use a directional high-gain antenna array to form an analog beam for communication. Generally speaking, an analog beam is directional, and a main lobe direction and a 3dB beam width can be used to describe an analog beam pattern. Among them, the narrower the beam width, the greater the antenna gain. Based on the analog beam, the network device and the terminal device can send and receive signals in a specific direction. Taking downlink communication as an example, the network device sends a signal in a specific direction, and the terminal device receives the signal in the specific direction. When the directions of the transmitted signal and the received signal are aligned, the network device and the terminal device can achieve normal communication. In order to achieve beam alignment (that is, the beam directions of the transmitter and the receiver are aligned), beam training is required.

[0003] In the existing protocol, downlink beam training is implemented by the network device sending one or more reference signals, and the terminal device measuring the reference signals sent by the network device and reporting the measurement results as required. Through downlink beam training, functions such as beam selection, beam quality measurement and reporting, and beam tracking can be achieved. The result of downlink beam training can be used by the network device for beam indication.

[0004] In 3GPP Release 16 (R16), in order to implement beam training based on L1 (layer 1, i.e., the physical layer)-SINR (abbreviated as SINR hereinafter), the network device is supported to configure one or more reference signal resource sets (channel measurement resource set, CMR set) for channel measurement, and one or more reference signal resource sets (interference measurement resource set, IMR set) for interference measurement. Moreover, the reference signal resources (CMR) in the CMR set and the reference signal resources (IMR) in the IMR set are in one-to-one correspondence. For example, CMR1 corresponds to IMR1, and CMR2 corresponds to IMR2. Such a resource correspondence method may increase resource overhead. Summary of the Invention

[0005] This application provides a method and apparatus for information reporting, which is beneficial to reducing resource overhead.

[0006] In a first aspect, the present application provides a method for information reporting. The method includes: receiving configuration information sent by a network device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, and N is an integer greater than 1. Wherein: if the identifiers of the N second resources are the same, the reception parameters of the N first resources are the same; measuring the signal strengths on the N first resources to obtain N first signal strengths; measuring the signal strength on the second resource to obtain a second signal strength; reporting one or more first signal-to-interference-plus-noise ratios (SINRs) to the network device, where the first SINR is the SINR obtained based on the N first signal strengths and the second signal strength.

[0007] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-located (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCL with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to 'QCL-TypeD').

[0008] In the method described in the first aspect, the identifiers of the N second resources included in the second resource set are the same, which can be understood as there is actually only one second resource in the second resource set. Therefore, based on the method described in the first aspect, it is beneficial to save the overhead of interference measurement resources.

[0009] In a possible implementation, if the identifiers of the N second resources are the same, the configuration information is further used to indicate that the reception parameters of the N first resources are the same. Based on this possible implementation, the network device can indicate to the terminal device that the reception parameters of the N first resources are the same. Alternatively, the terminal device can also determine whether the reception parameters of the N first resources are the same based on whether the identifiers of the N second resources are the same.

[0010] In a possible implementation, the specific implementation of measuring the signal strength on the second resource to obtain the second signal strength is as follows: measure the signal strength on the second resource once to obtain a second signal strength, and the reception parameters of the second resource are the same as those of the N first resources. Alternatively, the reception parameters of the second resource being the same as those of the N first resources can also be expressed as: the reception parameters of the second resource and the N first resources are QCL.

[0011] Based on this possible implementation, the terminal can measure multiple first resources and one second resource using the same reception parameters, which helps to reduce the measurement burden on the terminal device and the communication overhead of the network device.

[0012] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources among the N first resources. Based on this possible implementation, the terminal device can perform signal measurement on the N first resources and the second resource using the same reception parameter (i.e., the reception parameter of one or more resources among the N first resources).

[0013] In a possible implementation, the configuration information is further used to configure the reception parameters of the N first resources. Based on this implementation, the terminal device can perform signal measurement on the N first resources and the second resource using the same reception parameter (i.e., the configured reception parameters of the N first resources).

[0014] In a possible implementation, the configuration information is further used to configure the reception parameters of the second resource. Based on this implementation, the terminal device can perform signal measurement on the N first resources and the second resource using the same reception parameter (i.e., the configured reception parameters of the second resource).

[0015] In a second aspect, the present application provides an information reporting method, which includes: sending configuration information to a terminal device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, and N is an integer greater than 1. Wherein: if the identifiers of the N second resources are the same, the configuration information is further used to indicate that the reception parameters of the N first resources are the same; sending first reference signals on the N first resources respectively; sending a second reference signal on the second resource; and receiving one or more first signal-to-interference-plus-noise ratios (SINRs) reported by the terminal device.

[0016] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-located (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCLed with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to ‘QCL-TypeD).

[0017] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources among the N first resources, or the configuration information is further used to configure the reception parameters of the N first resources, or the configuration information is further used to configure the reception parameters of the second resources.

[0018] For the beneficial effects of the second aspect, reference can be made to the beneficial effects of the first aspect, which will not be elaborated here.

[0019] In a third aspect, the present application provides a method for information reporting. The method includes: receiving configuration information sent by a network device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, where N is an integer greater than 1. Among them: if the configuration information is further used to configure a third resource, the third resource is associated with the first resource set and is a resource of a zero-power reference signal for interference measurement, then the reception parameters of the N first resources are the same; measuring the signal strength on the first resources to obtain a first signal strength; measuring the signal strength on the second resources to obtain a second signal strength; measuring the interference strength on the third resources to obtain a first interference strength; reporting one or more first signal-to-interference-plus-noise ratios (SINRs) to the network device, where the first SINR is the SINR obtained based on the first signal strength, the second signal strength, and the first interference strength.

[0020] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-location (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCL with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to 'QCL-TypeD).

[0021] Based on the method described in the third aspect, by making the reception parameters of the N first resources the same, it is beneficial for the terminal device to successfully measure interference on the zero-power reference signal resource through the reception parameters of the first resources.

[0022] In a possible implementation, if the configuration information is also used to configure the third resource, the configuration information is also used to indicate that the reception parameters of the N first resources are the same. Based on this possible implementation, the network device can indicate to the terminal device that the reception parameters of the N first resources are the same. Alternatively, the terminal device can also determine whether the reception parameters of the N first resources are the same based on whether the configuration information configures the third resource.

[0023] In a possible implementation, the identifiers of the N first resources in the first resource set can be the same or different, that is, the N first resources can be the same resource or different resources.

[0024] In a possible implementation, the identifiers of the N second resources in the second resource set can be the same or different, that is, the N second resources can be the same resource or different resources.

[0025] In a possible implementation, the reception parameters of the N second resources, the reception parameters of the N first resources, and the reception parameters of the third resource are the same. Or, it can be expressed as: the reception parameters of the N second resources, the reception parameters of the N first resources, and the reception parameters of the third resource are quasi-co-location (QCL). Or, if the identifiers of the N first resources in the first resource set are the same (i.e., the N first resources are one resource), it can also be expressed as: the reception parameters of the N second resources, the reception parameters of the first resource, and the reception parameters of the third resource are the same. Or, if the identifiers of the N second resources in the second resource set are the same (i.e., the N second resources are one resource), it can also be expressed as: the reception parameters of the second resource, the reception parameters of the N first resources, and the reception parameters of the third resource are the same.

[0026] By implementing this possible implementation, the interference of the transmission parameters of the second resource on the transmission parameters and / or reception parameters of the first resource can be accurately measured.

[0027] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources among the N first resources. Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of one or more resources among the configured N first resources) to perform signal measurements on the first resource and the second resource, and interference measurements on the third resource.

[0028] In a possible implementation, the configuration information is further used to configure the reception parameters of the N first resources. Based on this implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of the configured N first resources) to perform signal measurements on the first resource and the second resource, and interference measurements on the third resource. If the identifiers of the N first resources in the first resource set are the same, it can also be expressed as: the configuration information is further used to configure the reception parameters of the first resource.

[0029] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources among the N second resources. Based on this implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of one or more resources among the configured N second resources) to perform signal measurements on the first resource and the second resource, and interference measurements on the third resource.

Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of the configured third resource) to perform signal measurements on the first resource and the second resource, and interference measurements on the third resource.

[0032] In a possible implementation, the identifiers of the N second resources in the second resource set are the same, and the reception parameters of the second resources are the same as those of the N first resources. The specific implementation of measuring the signal strength on the second resource to obtain the second signal strength is: measuring the signal strength on the second resource once to obtain a second signal strength. Based on this possible implementation, the terminal can use the same reception parameters to measure multiple first resources and one second resource, which is beneficial to reducing the measurement burden on the terminal device and reducing the communication overhead of the network device.

[0033] In a possible implementation, the configuration information is further used to configure the reception parameters of the third resource. Based on this possible implementation, the terminal can use the same reception parameters to measure multiple first resources and one second resource, which is beneficial to reducing the measurement burden on the terminal device and reducing the communication overhead of the network device.

[0034] In a fourth aspect, the present application provides an information reporting method, which includes: sending configuration information to a terminal device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, and N is an integer greater than 1. Wherein: if the configuration information is further used to configure a third resource, the third resource is associated with the first resource set, and the third resource is a resource for an interference measurement zero-power reference signal, then the configuration information is further used to indicate that the reception parameters of the N first resources are the same; sending a first reference signal on the first resource; sending a second reference signal on the second resource; receiving one or more first signal-to-interference-plus-noise ratios (SINRs) reported by the terminal device.

[0035] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-located (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCL with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to 'QCL-TypeD').

[0036] In a possible implementation, the identifiers of the N first resources in the first resource set can be the same or different, that is, the N first resources can be the same resource or different resources.

[0037] In a possible implementation, the identifiers of the N second resources in the second resource set can be the same or different, that is, the N second resources can be the same resource or different resources.

[0038] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more of the N first resources, or the configuration information is further used to configure the reception parameters of the N first resources, or the configuration information is further used to configure the reception parameters of one or more of the N second resources, or the configuration information is further used to configure the reception parameters of the N second resources, or the configuration information is further used to configure the reception parameters of the third resource.

[0039] In a possible implementation, if the identifiers of the N first resources in the first resource set are the same, the configuration information being further used to configure the reception parameters of the N first resources can also be expressed as: the configuration information is further used to configure the reception parameters of the first resource. In a possible implementation, if the identifiers of the N second resources in the second resource set are the same, the configuration information being further used to configure the reception parameters of the N second resources can also be expressed as: the configuration information is further used to configure the reception parameters of the second resource.

[0040] For the beneficial effects of the fourth aspect, reference can be made to the beneficial effects of the third aspect, which will not be elaborated here.

[0041] Fifth aspect, the present application provides a method for information reporting, the method comprising: receiving configuration information sent by a network device, the configuration information being used to configure a first resource set and a second resource set, resources corresponding to resource identifiers in the first resource set being used for channel measurement, resources corresponding to resource identifiers in the second resource set being used for interference measurement, the first resource set including identifiers of N first resources, the identifiers of the N first resources being the same, the second resource set including identifiers of N second resources, the identifiers of the N first resources corresponding one-to-one to the identifiers of the N second resources, N being an integer greater than 1; measuring a signal strength on a first resource to obtain a first signal strength; measuring signal strengths on N second resources to obtain N second signal strengths; reporting a first signal-to-interference-plus-noise ratio (SINR) to the network device based on the first signal strength and the N second signal strengths. Based on the method described in the first aspect, it is beneficial to save resource overhead.

[0042] In a possible implementation, reception parameters of the N second resources are the same as reception parameters of the first resource. Or, it can be expressed as: reception parameters of the N second resources are quasi-co-located (QCL) with reception parameters of the first resource. Or, it can be expressed as: the terminal device measures signal strengths on the N second resources by using reception parameters of the first resource. By implementing this possible implementation manner, it is possible to accurately measure interference of transmission parameters of the second resources on transmission parameters and / or reception parameters of the first resource.

[0043] In a possible implementation, a specific implementation manner of reporting the first SINR to the network device based on the first signal strength and the N second signal strengths is: determining N SINRs, where the i-th SINR among the N SINRs is obtained based on the first signal strength and the i-th second signal strength among the N second signal strengths, i being an integer greater than 0 and less than or equal to N; reporting one or more first SINRs among the N SINRs to the network device. By implementing this possible implementation manner, it is beneficial for the network device to determine interference of transmission parameters of one or more second resources on transmission parameters and / or reception parameters of the first resource. After the network device determines interference of transmission parameters of one or more second resources on transmission parameters and / or reception parameters of the first resource, during subsequent data transmission, beam co-transmission with relatively large mutual interference can be avoided through scheduling, or beam co-transmission with relatively small mutual interference can be paired.

[0044] In a possible implementation, report to the network device the positions of the identifiers of one or more first resources corresponding to the first SINR in the first resource set. Although the identifiers of the first resources in the first resource set are the same, the second resources used when calculating the SINR are different. Therefore, by reporting to the network device the positions of the identifiers of one or more first resources corresponding to the first SINR in the first resource set, it is beneficial for the network device to accurately determine the second resources used when calculating the SINR.

[0045] In a possible implementation, the first SINR is obtained based on the sum of N second signal strengths and the first signal strength. By implementing this possible implementation manner, the function of interference accumulation can be realized. When the interference environment experienced by the terminal device is relatively complex, the interference measurement can be made more accurate. Optionally, the first resource set further includes resource identifiers different from the identifiers of the first resources, and the positions of the identifiers of the first resources in the first resource set can also be reported to the network device. This is beneficial for the network device to accurately determine the second resources used when calculating the SINR.

[0046] In a sixth aspect, the present application provides a method for information reporting. The method includes: sending configuration information to the terminal device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the identifiers of the N first resources are the same. The second resource set includes the identifiers of N second resources, and the identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, where N is an integer greater than 1; sending a first reference signal on the first resource; sending second reference signals on the N second resources respectively; receiving the first signal-to-interference-plus-noise ratio (SINR) reported by the terminal device.

[0047] In a possible implementation, it is also possible to receive the positions of the identifiers of one or more first resources corresponding to the first SINR reported by the terminal device in the first resource set.

[0048] In a possible implementation, the first resource set further includes resource identifiers different from the identifiers of the first resources, and it is also possible to receive the positions of the identifiers of the first resources in the first resource set reported by the terminal device.

[0049] For the beneficial effects of the sixth aspect, reference can be made to the beneficial effects of the fifth aspect, which will not be elaborated here.

Based on the method described in the third aspect, it is beneficial to save resource overhead.

[0051] In a possible implementation, the specific implementation manner of measuring the signal strengths on the N first resources is: measuring the signal strengths on the N first resources through reception parameters of the N first resources; the specific implementation manner of performing N measurements on the signal strength on the second resource is: performing N measurements on the signal strength on the second resource through reception parameters of the N first resources. Or, it can be expressed as: reception parameters of each of the N second resources and its associated first resource are quasi-co-located (QCL). Or, it can be expressed as: reception parameters of each of the N second resources and its associated first resource are the same. By implementing this possible implementation manner, it is possible to accurately measure the interference of the transmission parameters of the second resource on the transmission parameters and / or reception parameters of the first resource.

[0052] In a possible implementation, the period of the second resource is 1 / N times the period of the first resource. In this possible implementation manner, the network device transmits reference signals of the second resource N times within a period of one first resource. By setting the period of the second resource to be 1 / N times the period of the first resource, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0053] In a possible implementation, the period of the second resource is the same as that of the first resource, and the time domain range for measuring N second signal strengths is less than or equal to the time length of one time unit. Optionally, one time unit is one OFDM symbol. Alternatively, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Alternatively, the time unit can also be one time slot, one subframe, one millisecond, etc. Alternatively, the time unit can also be two time slots, two subframes, two milliseconds, etc. By implementing this possible implementation, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0054] In a possible implementation, when the reception parameters of N first resources are the same, the signal strength on the second resource can also be measured once to obtain a second signal strength. The first SINR reported to the network device is the SINR among the N SINRs obtained based on the N first signal strengths and one second signal strength.

[0055] In an eighth aspect, the present application provides an information reporting method, which includes: sending configuration information to a terminal device, where the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, the second resource set includes the identifiers of N second resources, the identifiers of the N second resources are the same, the identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence, and N is an integer greater than 1; sending first reference signals on the N first resources; sending a second reference signal on the second resource; receiving one or more first signal-to-interference-plus-noise ratios (SINRs) reported by the terminal device.

[0056] In a possible implementation, the period of the second resource is 1 / N times the period of the first resource.

[0057] In a possible implementation, the period of the second resource is the same as that of the first resource.

Based on the method described in the fifth aspect, it is beneficial to save resource overhead.

[0060] In a possible implementation, the time domain range of the N measurements is less than or equal to the time length of one time unit. Optionally, one time unit is one OFDM symbol. Or, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Or, the time unit can also be one time slot, one subframe, one millisecond, etc. Or, the time unit can also be two time slots, two subframes, two milliseconds, etc. By implementing this possible implementation manner, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0061] In a possible implementation, the time domain measurement range of each of the N measurements is less than or equal to N IFFT / N, where N IFFT is the time length of one time unit.

[0062] In a possible implementation, the time domain measurement range of each of the N measurements is less than or equal to N IFFT / N - N CP / N, where N CP is the time length of the cyclic prefix, and N IFFT is the time length of one time unit. The cyclic prefix is a guard interval. Therefore, it should be ensured that the time domain measurement range of each of the N measurements is less than or equal to N IFFT / N - N CP / N.

[0063] In a possible implementation, the N measurements are performed after the cyclic prefix.

[0064] In a possible implementation, the configuration information further includes a repetition factor. When the repetition factor is off, the position of the identifier of the first resource corresponding to the first signal strength in the first resource set can also be reported to the network device. This is beneficial for the network device to determine the transmission parameters used for measuring the first signal strength.

Optionally, one time unit is one OFDM symbol. Or, one time unit may also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Or, the time unit may also be one time slot, one subframe, one millisecond, etc. Or, the time unit may also be two time slots, two subframes, two milliseconds, etc.

[0068] In a possible implementation, a time domain range of each time of sending the reference signal is less than or equal to N IFFT / N, N IFFT is a time length of one time unit.

[0101] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0102] Terms such as "first" and "second" in the specification, claims and drawings of the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0103] Reference to "embodiment" in this text means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0104] In this application, "at least one (item)" means one or more, "a plurality" means two or more, "at least two (items)" means two or three and three or more, and "and / or" is used to describe the corresponding relationship of the corresponding objects, indicating that there can be three relationships. For example, "A and / or B" can mean: only A exists, only B exists, and both A and B exist at the same time. Among them, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the corresponding objects before and after. "At least one (one)" or its similar expression below refers to any combination of these items, including any combination of single item (one) or plural items (ones). For example, at least one (one) of a, b, or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0105] 3GPP R16 introduced a beam management mechanism based on L1-SINR (layer 1-SINR). For beam management based on L1-SINR, the protocol allows dedicated configuration of interference measurement resources (IMR). There is a one-to-one correspondence between IMR and channel measurement resources (CMR), that is, one CMR configures one IMR. IMR resources are used for the terminal device to measure interference and noise. CMR resources are used for the terminal device to perform channel measurement. IMR resources and CMR resources can be collectively referred to as CSI-RS resources.

[0106] The following details the related configurations of the existing reference signal measurement and reporting for beam training:

[0107] For example, as Figure 1As shown, the reporting quantity configured for a network device for a reporting setting (ReportConfig#1) is CRI-SINR, and this reporting setting (ReportConfig#1) corresponds to two resource settings (ResourceConfig), namely a channel measurement resource setting (ResourceConfig#1) and an interference measurement resource setting (ResourceConfig#2). The channel measurement resource setting has a function label of channel measurement (resourcesForChannelMeasurement). The interference measurement resource setting has a function label of interference measurement (resourcesForInterferenceMeasurement).

[0108] RsourceConfig#1 contains a list of resource sets (ResourceSetList). Among them, this list of resource sets includes M (>=1) resource sets. For example, it includes resource set #1 (resourceset#1), etc. RsourceConfig#2 also contains a list of resource sets (ResourceSetList). Among them, this list of resource sets includes M (>=1) resource sets, such as resource set #2 (resourceset#2), etc. Resource set #1 (resourceset#1) includes Y (>=1) CMR resources. For example, Figure 1 taking resource set #1 including CSI-RS resource #1 (CSI-RS resource#1) and CSI-RS resource #2 (CSI-RS resource#2) as an example. Resource set #2 includes Y (>=1) IMR resources. For example, Figure 1 taking resource set #2 (resourceset#2) including CSI-RS resource #11 (CSI-RSresource#11) and CSI-RS resource #12 (CSI-RS resource#12) as an example. Among them, CSI-RS resource#1 corresponds to CSI-RS resource#11, and CSI-RS resource#2 corresponds to CSI-RS resource#12.

[0109] However, Figure 1 the resource configuration shown may increase the overhead of CMR resources. For example, as Figure 2As shown, assume that the transmission parameters corresponding to CSI-RS resource#1 and CSI-RS resource#2 are the same, and the transmission parameters corresponding to both CSI-RS resource#1 and CSI-RS resource#2 are beam a1. The reception parameters corresponding to CSI-RS resource#1 and CSI-RS resource#2 are also the same, and the reception parameters corresponding to both CSI-RS resource#1 and CSI-RS resource#2 are beam b1. The transmission parameter corresponding to CSI-RS resource#11 is beam a2, and the transmission parameter corresponding to CSI-RS resource#12 is beam a3.

[0110] The network device transmits the reference signal CSI-RS1 using beam a1 on CSI-RS resource#1, and transmits the reference signal CSI-RS11 using beam a2 on CSI-RS resource#11. The terminal device measures the signal strength 1 of CSI-RS1 through beam b1, and measures the signal strength 2 of CSI-RS11 through beam b1. The terminal device determines the ratio of signal strength 1 to signal strength 2 as SINR1 and reports SINR1 to the network device. Then the network device transmits the reference signal CSI-RS2 using beam a1 on CSI-RS resource#2, and transmits the reference signal CSI-RS12 using beam a3 on CSI-RS resource#12. The terminal device measures the signal strength 3 of CSI-RS2 through beam b1, and measures the signal strength 4 of CSI-RS12 through beam b1. The terminal device determines the ratio of signal strength 3 to signal strength 4 as SINR2 and reports SINR2 to the network device.

[0111] That is to say, Figure 1The resource allocation is used to measure the interference of beam a2 and beam a3 on the same pair of beams (beam a1 and beam b1). In this case, the terminal device actually only needs to perform one channel measurement, that is, only one CMR resource needs to be configured corresponding to multiple IMR resources. For example, CSI-RS resource #1 is included in resource set #1, and CSI-RS resource #11 and CSI-RS resource #12 are included in resource set #2. In this way, CSI-RS resource #1 can correspond to CSI-RS resource #11 and CSI-RS resource #12 at the same time. However, due to the protocol stipulation that the CMR resource and the IMR resource must correspond one by one, one CMR resource cannot correspond to multiple IMR resources at the same time. Therefore, in the existing correspondence between CMR resources and IMR resources, when measuring the interference of multiple beams on the same pair of beams, usually different CMR resources are configured for different IMR resources. It can be seen that this increases the overhead of CMR resources.

[0112] Therefore, in order to reduce the overhead of CMR resources, the embodiments of this application provide an information reporting method. To better understand the embodiments of this application, the system architecture of the embodiments of this application will be described first:

[0113] The method provided by the embodiments of this application can be applied to various communication systems. For example, it can be an Internet of Things (IoT) system, a Narrow Band Internet of Things (NB-IoT) system, a Long Term Evolution (LTE) system, or a 5th-generation (5G) communication system. It can also be an LTE and 5G hybrid architecture, a 5G New Radio (NR) system, and new communication systems emerging in the future development of communication, etc.

[0114] Figure 3 It is a schematic diagram of the architecture of a communication system provided by the embodiments of this application, and the solution in this application is applicable to this communication system. This communication system may include at least one network device and at least one terminal device. Figure 3 Taking the example that the communication system includes one network device and one terminal device. As Figure 3 shown, the network device and the terminal device can communicate through beams. Both the network device and the terminal device can generate multiple beams. Figure 3 Taking the example that the network device can send beam a1 to beam a3, and the receiving beams of the terminal device include beam b1 and beam b2.

[0115] In the embodiments of the present application, the network device involved is an entity on the network side for transmitting or receiving signals, which can be used to mutually convert received air frames and Internet Protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network, etc. The network device can also coordinate the attribute management of the air interface. For example, the network device can be an evolved Node B (eNB or e-NodeB) in LTE, can also be a new radio controller (NR controller), can be a gNode B (gNB) in a 5G system, can be a centralized unit, can be a new radio base station, can be a remote radio unit, can be a micro base station, can be a relay, can be a distributed unit, can be a transmission reception point (TRP) or a transmission point (TP), or any other radio access device, but the embodiments of the present application are not limited thereto.

[0116] The terminal device involved in the embodiments of the present application is an entity on the user side for receiving or transmitting signals. The terminal device can be a device that provides voice and / or data connectivity to the user. For example, it can be a handheld device, a vehicle-mounted device, etc. with wireless connection capabilities. The terminal device can also be other processing devices connected to a wireless modem. The terminal device can communicate with a radio access network (RAN). The terminal device can also be referred to as a wireless terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE), etc. The terminal device can be a mobile terminal, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted mobile device that exchanges voice and / or data with the wireless access network. For example, the terminal device can also be a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. Common terminal devices include, for example, mobile phones, tablet computers, laptop computers, palm computers, mobile internet devices (MIDs), wearable devices, such as smart watches, smart bracelets, pedometers, etc., but the embodiments of the present application are not limited thereto.

[0117] The following further describes in detail the information reporting method provided by the embodiments of the present application:

[0118] Please refer to Figure 4 , Figure 4 which is a schematic flowchart of an information reporting method provided by the embodiments of the present application. As Figure 4 shown, the information reporting method includes the following steps 401 to 406. Figure 4The execution subject of the method shown can be a network device and a terminal device, or the subject can be a chip in the network device and a chip in the terminal device. Figure 4 Taking the network device and the terminal device as the execution subject of the method as an example for illustration. The execution subject of the information reporting method shown in other drawings of the embodiments of the present application is the same, and will not be elaborated hereinafter. Among them:

[0119] 401. The network device sends configuration information to the terminal device.

[0120] Among them, the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, the identifiers of the N first resources are the same, the second resource set includes the identifiers of N second resources, and the identifiers of the N first resources are in one-to-one correspondence (or association) with the identifiers of the N second resources, where N is an integer greater than 1.

[0121] Since the first resource set includes the identifiers of N first resources, and the identifiers of the N first resources are the same. Therefore, it can be understood that the first resource set includes N identical first resources, or it can be understood that the first resource set includes one first resource.

[0122] Among them, the identifiers of the N second resources included in the second resource set may be the same or different. If the identifiers of the N second resources are the same, it means that the second resource set includes N identical second resources. If the identifiers of the N second resources are different, it means that the second resource set includes N different second resources.

[0123] For example, as Figure 5 shown, the first resource set is the resource set corresponding to resource set #1 (resourceset#1). The second resource set is the resource set corresponding to resource set #2 (resourceset#2). Among them, the first resource set includes the identifiers of two identical first resources, and the identifier of the first resource is CSI-RS resource#1. The second resource set includes the identifiers of two second resources, which are CSI-RS resource#11 and CSI-RS resource#12 respectively. The first CSI-RS resource#1 corresponds to CSI-RS resource#11, and the second CSI-RS resource#1 corresponds to CSI-RSresource#12. That is to say, the first resource set includes two identical first resources, and the second resource set includes two different second resources.

[0124] Optionally, the configuration information further includes a repetition factor. When the repetition factor is enabled, it means that the transmission parameters of N first resources are the same transmission parameter. When the repetition factor is disabled, it means that the transmission parameters of N first resources are not the same transmission parameter. For example, as Figure 5 shown, the repetition factor is repetition, and this repetition factor is enabled. "Repetition: ON" means the repetition factor is enabled. "Repetition: OFF" means the repetition factor is disabled.

[0125] 402. The network device sends a first reference signal on the first resource.

[0126] 403. The network device sends second reference signals on N second resources respectively.

[0127] In the embodiments of this application, after the network device sends the configuration information to the terminal device, the network device can send a first reference signal on the first resource and send second reference signals on N second resources respectively.

[0128] 404. The terminal device measures the signal strength on the first resource to obtain a first signal strength.

[0129] 405. The terminal device measures the signal strength on N second resources to obtain N second signal strengths.

[0130] In the embodiments of this application, after the terminal device receives the configuration information sent by the network device, it can measure the first signal strength on the first resource and measure the signal strength on N second resources to obtain N second signal strengths.

[0131] In a possible implementation, the reception parameters of N second resources are the same as the reception parameters of the first resource. Or, it can be expressed as: the reception parameters of N second resources are quasi-co-location (QCL) with the reception parameters of the first resource. Or, it can be expressed as: the terminal device measures the signal strength on N second resources through the reception parameters of the first resource. By implementing this possible method, the interference situation of the transmission parameters of the second resource on the transmission parameters and / or reception parameters of the first resource can be accurately measured.

[0132] For example, taking the measurement performed by the terminal device within a measurement result reporting period as an example for illustration. As Figure 6As shown, a measurement result reporting period is 10 ms. The period of CSI-RS resource #1 is 10 ms. The period of CSI-RS resource #11 is 10 ms. The period of CSI-RS resource #12 is 10 ms. Within a measurement result reporting period, the terminal device measures a total of 3 reference signals, namely CSI-RS1 transmitted on the resource corresponding to CSI-RS resource #1, CSI-RS11 transmitted on the resource corresponding to CSI-RS resource #11, and CSI-RS12 transmitted on the resource corresponding to CSI-RS resource #12. Among them, the transmission parameter of CSI-RS resource #1 is beam a1, the transmission parameter of CSI-RS resource #11 is beam a2, and the transmission parameter of CSI-RS resource #12 is beam a3. The reception parameter of CSI-RS resource #1 is beam b1. The terminal device measures the signal strength of CSI-RS1 on the resource corresponding to CSI-RS resource #1 through beam b1 to obtain the first signal strength P1. The terminal device measures the signal strength of CSI-RS11 on the resource corresponding to CSI-RS resource #11 through beam b1 to obtain the second signal strength P11. The terminal device measures the signal strength of CSI-RS12 on the resource corresponding to CSI-RS resource #12 through beam b1 to obtain the second signal strength P12. It can be seen that within a measurement result reporting period, the terminal device only performs one channel measurement.

[0133] In a possible implementation, the signal strength can be signal reception power, signal reception energy, etc.

[0134] 406. The terminal device reports a first SINR to the network device based on the first signal strength and N second signal strengths.

[0135] In the embodiments of this application, after the terminal device measures the first signal strength and N second signal strengths, it can report the first SINR to the network device based on the first signal strength and N second signal strengths.

[0136] The following introduces two specific implementation manners for the terminal device to report the first SINR to the network device based on the first signal strength and N second signal strengths:

[0137] Method 1: The terminal device determines N SINRs. The i-th SINR among the N SINRs is obtained based on the first signal strength and the i-th second signal strength among the N second signal strengths, where i is an integer greater than 0 and less than or equal to N; the terminal device reports one or more first SINRs among the N SINRs to the network device.

[0138] For example, the terminal device measures the above-mentioned first signal strength P1, second signal strength P11, and second signal strength P12. The terminal device can determine two SINRs. SINR1 = P1 / (P11 + N1). SINR2 = P1 / (P12 + N2). Among them, N1 and N2 are noise powers. N1 and N2 can be the same or different. The terminal device can determine how many SINRs to report according to the beam reporting number predefined by the protocol or configured by the network device. For example, if the beam reporting number predefined by the protocol or configured by the network device is 2, the terminal device can report SINR1 and SINR2 to the network device. Or, if the beam reporting number predefined by the protocol or configured by the network device is 1, the terminal device can report the maximum or minimum value of SINR1 and SINR2 to the network device.

[0139] By implementing Embodiment 1, it is beneficial for the network device to determine the interference situation of the transmission parameters of one or more second resources on the transmission parameters and / or reception parameters of the first resource. After the network device determines the interference situation of the transmission parameters of one or more second resources on the transmission parameters and / or reception parameters of the first resource, during subsequent data transmission, it can avoid co-transmission of beams with large mutual interference through scheduling, or pair co-transmission of beams with small mutual interference.

[0140] Optionally, the network device can also instruct the terminal device to report the maximum SINR or the minimum SINR. Or, the network device can also instruct the terminal device to report the beams with large mutual interference or the beams with small mutual interference. For example, it instructs the terminal device to report the SINRs greater than or less than a preset threshold.

[0141] In a possible implementation, the terminal device can also report to the network device the positions of the identifiers of the first resources corresponding to the one or more first SINRs in the first resource set. For example, if the terminal device reports SINR1 and SINR2 to the network device, then the terminal device reports that the position of CSI-RS resource#1 corresponding to SINR1 in the first resource set is the first position, and the position of CSI-RS resource#1 corresponding to SINR2 in the first resource set is the second position.

[0142] Although the identifiers of the first resources in the first resource set are the same, the second resources used when calculating the SINR are different. Therefore, by reporting to the network device the positions of the identifiers of the first resources corresponding to the one or more first SINRs in the first resource set, it is beneficial for the network device to accurately determine the second resources used when calculating the SINR.

[0143] Among them, the position of the first resource corresponding to the first SINR in the first resource set is indicated by X bits, and the K is the number of different resource identifiers in the first resource set, and the N i is the number of repetitions of the i-th resource identifier among the K resource identifiers. is the total number of identifiers included in the first resource set. For example, in Figure 5 the configuration shown, K is 1. N i is 2. Therefore, N is 2. Therefore, the position of the first resource corresponding to the first SINR in the first resource set is indicated by 1 bit. For example, if the bit value is 0, it means that the position of the first resource corresponding to the first SINR in the first resource set is the first position; if the bit value is 1, it means that the position of the first resource corresponding to the first SINR in the first resource set is the second position.

[0144] Method 2: The first SINR is obtained based on the sum of N second signal strengths and the first signal strength. In Method 2, the terminal device obtains only one SINR based on the first signal strength and N second signal strengths. For example, the first SINR == P1 / (P11 + P12 + N1). By implementing Method 2, the function of interference accumulation can be achieved. When the interference environment experienced by the terminal device is relatively complex, the interference measurement can be made more accurate. For example, when the network device communicates with the target terminal device through a service beam, it also communicates with other terminal devices through other beams. The target terminal device will be affected by multiple interference beams. At this time, the network device can simulate the transmission of multiple interference beams on multiple second resources, and the target terminal device can accumulate the interference measured on the multiple second resources.

[0145] Following the guidance of RAN1, supporting option 2a (i.e., one CMR is associated with multiple IMRs) should have no RRC impact. This means that the base station can only configure a list containing N CMRs and another list containing N IMRs, and the CMRs and IMRs are in one-to-one correspondence. As a solution, the N CMRs in this list containing N CMRs can be configured with the same CSI-RS resource identifier, implicitly notifying the terminal that the option 2a method should be adopted to accumulate the measurement results of the associated N IMRs when calculating interference. Proposal X: Support the L1-SINR reporting of option 2a (i.e., one CMR is associated with multiple IMRs) by configuring a list of CMR resources with the same CSI-RS resource ID.

[0146] In a possible implementation, if all the identifiers in the first resource set are the same, in the second method, the terminal device may not report the position of the first resource in the first resource set to the network device.

[0147] In a possible implementation, if the first resource set further includes a resource identifier different from the identifier of the first resource, then in Method 2, the terminal device may report the position of the first resource in the first resource set to the network device. For example, the position of the first resource in the first resource set is indicated by X bits, and the K is the number of different resource identifiers in the first resource set. For example, Figure 5 if the first resource set includes, in addition to 2 CSI-RS resource#1, 2 CSI-RS resource#2, then K is 2 and X is 1.

[0148] In a possible implementation, the protocol predefines or the network device may instruct the terminal device to report the first SINR in the above Method 1 or Method 2.

[0149] In a possible implementation, the terminal device may report capability information indicating whether the terminal device supports Figure 4 the method described in the corresponding embodiment.

[0150] In a possible implementation, the protocol predefines or the network device may instruct the terminal device to execute Figure 4 the method described in the corresponding embodiment.

[0151] In Figure 4 the method described, the network device configures the identifiers of N identical first resources in the first resource set and configures the identifiers of N first resources in the second resource set, and the N identifiers of the first resources correspond one-to-one to the N identifiers of the second resources. Therefore, by implementing Figure 4 the method described, it is beneficial to save resource overhead.

[0152] The above embodiments introduce how to save the overhead of CMR resources. Next, in combination with Figure 7 how to save the overhead of IMR resources will be introduced:

[0153] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of another information reporting method provided by an embodiment of the present application. As Figure 7 shown, the information reporting method includes the following steps 701 to step 706. Figure 7 The execution subject of the method shown can be the network device and the terminal device, or the execution subject can be the chip in the network device and the chip in the terminal device. Figure 7 Taking the network device and the terminal device as the execution subjects of the method as an example for illustration. The execution subjects of the information reporting methods shown in other drawings of the embodiments of the present application are the same by analogy, and will not be elaborated hereinafter. Among them:

[0154] 701. The network device sends configuration information to the terminal device.

[0155] Among them, the configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N second resources are the same, and the identifiers of the N first resources are in one-to-one correspondence with the identifiers of the N second resources. N is an integer greater than 1.

[0156] Since the second resource set includes the identifiers of N second resources and the identifiers of the N second resources are the same. Therefore, it can be understood that the second resource set includes N identical second resources, or it can be understood that the second resource set includes one second resource.

[0157] Among them, the identifiers of the N first resources included in the first resource set may be the same or different. If the identifiers of the N first resources are the same, it means that the first resource set includes N identical first resources. If the identifiers of the N first resources are different, it means that the first resource set includes N different first resources.

[0158] For example, as Figure 8 shown, the first resource set is the resource set corresponding to resource set #1 (resourceset#1). The second resource set is the resource set corresponding to resource set #2 (resourceset#2). Among them, the first resource set includes the identifiers of two first resources, namely CSI-RS resource#1 and CSI-RS resource#2. The second resource set includes the identifiers of two identical second resources, and the identifier of the second resource is CSI-RS resource#11. CSI-RSresource#1 corresponds to the first CSI-RS resource#11, and CSI-RS resource#2 corresponds to the second CSI-RSresource#11. That is to say, the first resource set includes two different first resources, and the second resource set includes two identical second resources.

[0159] Optionally, the configuration information further includes a repetition factor. When the repetition factor is enabled, it means that the transmission parameters of the N first resources are the same transmission parameter. When the repetition factor is disabled, it means that the transmission parameters of the N first resources are not the same transmission parameter. For example, as Figure 8As shown, the repetition factor is repetition, and this repetition factor is off. "Repetition: ON" means the repetition factor is on. "Repetition: OFF" means the repetition factor is off.

[0160] 702. The network device sends first reference signals on N first resources respectively.

[0161] 703. The network device sends a second reference signal on a second resource.

[0162] In the embodiments of this application, after the network device sends configuration information to the terminal device, the network device can send first reference signals on N first resources respectively and send a second reference signal on the second resource.

[0163] 704. The terminal device measures the signal strengths on N first resources to obtain N first signal strengths.

[0164] 705. The terminal device measures the signal strength on the second resource N times to obtain N second signal strengths.

[0165] In the embodiments of this application, after the terminal device receives the configuration information sent by the network device, it can measure the signal strengths on N first resources to obtain N first signal strengths, and measure the signal strength on the second resource N times to obtain N second signal strengths.

[0166] In a possible implementation, the specific implementation manner for the terminal device to measure the signal strengths on N first resources is: measuring the signal strengths on N first resources through the reception parameters of the N first resources; the specific implementation manner for the terminal device to measure the signal strength on the second resource N times is: measuring the signal strength on the second resource N times through the reception parameters of the N first resources.

[0167] Or, it can be expressed as: The reception parameters of each second resource among the N second resources and its associated first resource are QCL. Or, it can be expressed as: The reception parameters of each second resource among the N second resources and its associated first resource are the same.

[0168] In a possible implementation, the period of the second resource is 1 / N times the period of the first resource. In this possible implementation manner, the network device sends reference signals N times on the second resource within one period of the first resource. By setting the period of the second resource to be 1 / N times the period of the first resource, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improving the speed of beam training.

[0169] For example, taking the measurements performed by the terminal device within one measurement result reporting period as an example for illustration. As Figure 9As shown, the transmission parameters of CSI-RS resource#1 and CSI-RS resource#2 are different, and the reception parameters are also different. The period of CSI-RS resource#1 and CSI-RS resource#2 is 10 ms (milliseconds). A measurement result reporting period is 10 ms. The period of CSI-RS resource#11 is 5 ms. The terminal device measures the signal strength once at the resource corresponding to CSI-RS resource#1 and once at the resource corresponding to CSI-RS resource#2. The terminal device measures the signal strength twice at the resource corresponding to CSI-RS resource#11 within one measurement result reporting period.

[0170] Among them, the transmission parameter of CSI-RS resource#1 is beam a1, the transmission parameter of CSI-RS resource#2 is beam a2, and the transmission parameter of CSI-RS resource#11 is beam a3. The reception parameter of CSI-RS resource#1 is beam b1. The terminal device measures the signal strength of CSI-RS1 at the resource corresponding to CSI-RS resource#1 through beam b1 to obtain the first signal strength P1. The terminal device measures the signal strength of CSI-RS2 at the resource corresponding to CSI-RS resource#2 through beam b2 to obtain the first signal strength P2. The network device transmits CSI-RS11 twice at CSI-RS resource#11 through beam a3 within 10 ms. The terminal device measures the signal strength of the first transmitted CSI-RS11 through beam b1 to obtain the second signal strength P11. The terminal device measures the signal strength of the second transmitted CSI-RS11 through beam b2 to obtain the second signal strength P12. It can be seen that if the period of the second resource is the same as that of the first resource, then it takes 20 ms to measure the signal strength of CSI-RS11 twice. One measurement result reporting period will become 20 ms. Therefore, by setting the period of the second resource to 1 / N times that of the first resource, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0171] In a possible implementation, the period of the second resource is the same as that of the first resource, and the time domain range for measuring N second signal strengths is less than or equal to the time length of one time unit, that is, the total duration for measuring N second signal strengths is less than or equal to the time length of one time unit. Optionally, one time unit is an Orthogonal Frequency Division Multiplexing (OFDM) symbol. Or, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Or, the time unit can also be one time slot, one subframe, one millisecond, etc. Or, the time unit can also be two time slots, two subframes, two milliseconds, etc. By implementing this possible implementation method, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0172] For example, in Figure 9 , the periods of CSI-RS resource#1 and CSI-RS resource#2 are 10 ms (milliseconds). One measurement result reporting period is 10 ms. The period of CSI-RS resource#11 is 10 ms. The terminal device measures the signal strength of CSI-RS1 through beam b1 in the resource corresponding to CSI-RS resource#1 to obtain the first signal strength P1. The terminal device measures the signal strength of CSI-RS2 through beam b2 in the resource corresponding to CSI-RS resource#2 to obtain the first signal strength P2. The network device sends CSI-RS11 once in the resource corresponding to CSI-RS resource#11 through beam a3 within 10 ms. The duration for the network device to send CSI-RS11 once is equal to one OFDM symbol. Within one OFDM symbol, the terminal device measures the signal strength of CSI-RS11 twice in total. When measuring for the first time, the terminal device measures the signal strength of CSI-RS11 through beam b1 to obtain the second signal strength P11. When measuring for the second time, the terminal device switches to beam b2 to measure the signal strength of CSI-RS11 to obtain the second signal strength P12.

[0173] In a possible implementation, the time domain range for each measurement of the second signal strength is less than or equal to N IFFT / N - N CP / N, where the N CP is the time length of the cyclic prefix, and this N IFFT is the time length of one time unit.

[0174] In a possible implementation, the measurement of N second signal strengths is performed after the cyclic prefix.

[0175] 706. The terminal device reports one or more first SINRs to the network device.

[0176] In the embodiments of the present application, the first SINR is the SINR among N SINRs obtained based on N first signal strengths and N second signal strengths.

[0177] For example, the terminal device measures the above-mentioned first signal strength P1, first signal strength P2, second signal strength P11, and second signal strength P12. The terminal device can determine 2 SINRs. SINR1 = P1 / (P11 + N1). SINR2 = P2 / (P12 + N2). Wherein, N1 and N2 are noise powers. N1 and N2 can be the same or different. The terminal device can report SINR1 and SINR2 to the network device. Alternatively, the terminal device can report the maximum value or the minimum value of SINR1 and SINR2 to the network device.

[0178] In a possible implementation, the terminal device reports one first SINR to the network device, and the first SINR is obtained based on the sum of N first signal strengths and the sum of N second signal strengths. For example, the first SINR = (P1 + P2) / (P11 + P12 + N1). Through this possible implementation, the function of interference accumulation can be achieved. When the interference environment experienced by the terminal device is relatively complex, the interference measurement can be made more accurate.

[0179] In a possible implementation, if the terminal device measures the first signal strength once within the time length of one time unit and measures the second signal strength N times within the time length of one time unit, when calculating the SINR, it is necessary to consider scaling the measured signal strengths. That is to say, the terminal device determines the SINR based on the first signal strength, the second signal strength, and the scaling factor. The scaling factor is related to N. For example, the scaling factor is equal to N or an integer multiple of N. For example, the terminal device measures the first signal strength P1, first signal strength P2, second signal strength P11, and second signal strength P12. SINR1 = P1 / (2 * P11 + N1), SINR2 = P2 / (2 * P12 + N2). Or, SINR1 = 0.5 * P1 / (P11 + N1), SINR2 = 0.5 * P2 / (P12 + N2).

[0180] Optionally, assume that the number of CSI processing units (CPUs) required for the terminal device to measure the first signal strength once within the time length of one time unit is 1. If the terminal device needs to measure the second signal strength N times within the time length of one time unit, then the number of CSI processing units (CPUs) required for the terminal device to process the second resource is W, where W is a number greater than 1 and less than or equal to N.

[0181] In a possible implementation, when the reception parameters of the N first resources are the same, the signal strength on the second resource can also be measured once to obtain a second signal strength. The first SINR reported to the network device is the SINR among the N SINRs obtained based on the N first signal strengths and one second signal strength.

[0182] For example, Figure 8 the reception parameters of CSI-RS resource#1 and CSI-RS resource#2 in [[ ]] are the same, both being beam b1. The terminal device measures the signal strength of CSI-RS1 on the resource corresponding to CSI-RS resource#1 through beam b1 to obtain the first signal strength P1. The terminal device measures the signal strength of CSI-RS2 on the resource corresponding to CSI-RS resource#2 through beam b1 to obtain the first signal strength P2. The terminal device measures the signal strength of CSI-RS11 on the resource corresponding to CSI-RS resource#11 through beam b1 to obtain the second signal strength P11. The terminal device can obtain SINR1 = P1 / (P11 + N1) and SINR2 = P2 / (P11 + N2). The terminal device reports one or more of SINR1 and SINR2 to the network device.

[0183] In a possible implementation, the terminal device measures the signal strength on the second resource Z times to obtain Z second signal strengths. Where Z is the number of different reception parameters in the first resource set.

[0184] In a possible implementation, the period of the second resource is 1 / Z times the period of the first resource. Where Z is the number of different reception parameters in the first resource set.

[0185] In a possible implementation, the terminal device can report capability information indicating whether the terminal device supports Figure 7 the method described in the corresponding embodiment.

[0186] In a possible implementation, the protocol predefines or the network device can instruct the terminal device to execute Figure 7 the method described in the corresponding embodiment.

[0187] In Figure 7 the method described, the network device configures the identifiers of N first resources in the first resource set and configures the identifiers of N identical first resources in the second resource set. The identifiers of the N first resources correspond one-to-one with the identifiers of the N second resources. Therefore, by implementing Figure 7 the method described, it is beneficial to save resource overhead.

[0188] The following combines Figure 18 to introduce how to save the overhead of IMR resources:

[0189] Please refer to Figure 18 , Figure 18 which is a schematic flowchart of another information reporting method provided by an embodiment of the present application. As Figure 18 shown, the information reporting method includes the following steps 1801 to 1806. Among them:

[0190] 1801. The network device sends configuration information to the terminal device.

[0191] Among them, the configuration information is used to configure the first resource set and the second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, the second resource set includes the identifiers of N second resources, the identifiers of the N first resources correspond one-to-one with the identifiers of the N second resources, and N is an integer greater than 1. Among them: if the identifiers of the N second resources are the same, the reception parameters of the N first resources are the same.

[0192] For example, the first resource set and the second resource set configured by the configuration information can be as Figure 8 shown. Among them, the introduction of the configuration information can refer to the description under the above step 701 and will not be elaborated here.

[0193] In a possible implementation, the reception parameter throughout the present application can be a QCL type D (quasi-co-location type D) parameter, or a QCL type A (quasi-co-location type A) parameter, etc.

[0194] In a possible implementation, the first resource set can be a non-zero power CSI-RS resource set for channel measurement. The second resource set can be a non-zero power CSI-RS resource set for interference measurement.

[0195] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-located (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCL with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to 'QCL-TypeD').

[0196] In a possible implementation, if the identifiers of the N second resources are the same, the configuration information is further used to indicate that the reception parameters of the N first resources are the same. Based on this possible implementation, the network device may indicate that the reception parameters of the N first resources are the same to the terminal device. Alternatively, the terminal device may also determine whether the reception parameters of the N first resources are the same based on whether the identifiers of the N second resources are the same.

[0197] 1802. The network device sends first reference signals on the N first resources.

[0198] 1803. The network device sends second reference signals on the second resource.

[0199] 1804. The terminal device measures the signal strengths on the N first resources to obtain N first signal strengths.

[0200] 1805. The terminal device measures the signal strength on the second resource to obtain a second signal strength.

[0201] In a possible implementation, the specific implementation manner for the terminal device to measure the signal strength on the second resource to obtain a second signal strength is: measuring the signal strength on the second resource once to obtain a second signal strength, and the reception parameters of the second resource are the same as those of the N first resources. Alternatively, the reception parameters of the second resource being the same as those of the N first resources can also be expressed as: the reception parameters of the second resource are QCL with those of the N first resources.

[0202] Based on this possible implementation, the terminal device can measure multiple first resources and one second resource using the same reception parameters, which helps to reduce the measurement burden of the terminal device and the communication overhead of the network device.

[0203] Alternatively, it is also possible to perform N measurements on the signal strength on the second resource through the reception parameters of N first resources to obtain N second signal strengths, which is not limited in the embodiments of the present application.

[0204] 1806. The terminal device reports one or more first SINRs to the network device.

[0205] In the embodiments of the present application, the first SINR is the SINR obtained based on the second signal strength and N first signal strengths.

[0206] For example, taking the case where the signal strength of the terminal device on the second resource is measured only once as an example. Figure 8 The reception parameters of CSI-RSresource#1 and CSI-RS resource#2 in are the same, both being beam b1. The terminal device measures the signal strength of CSI-RS1 through beam b1 on the resource corresponding to CSI-RS resource#1 to obtain the first signal strength P1. The terminal device measures the signal strength of CSI-RS2 through beam b1 on the resource corresponding to CSI-RS resource#2 to obtain the first signal strength P2. The terminal device measures the signal strength of CSI-RS11 through beam b1 on the resource corresponding to CSI-RS resource#11 to obtain the second signal strength P11. The terminal device can obtain SINR1 = P1 / (P11 + N1), SINR2 = P2 / (P11 + N2). The terminal device reports one or more of SINR1 and SINR2 to the network device.

[0207] It can be seen that in Figure 18 the method described, the identifiers of the N second resources included in the second resource set are the same, that is, it can be understood that there is actually only one second resource in the second resource set. Therefore, based on Figure 18 the method described, it is beneficial to save the overhead of interference measurement resources.

[0208] In a possible implementation, the configuration information is also used to configure the reception parameters of one or more resources among the N first resources. Based on this possible implementation manner, the terminal device can use the same reception parameter (i.e., the reception parameters of one or more resources among the configured N first resources) to perform signal measurement on the N first resources and the second resource.

[0209] For example, taking Figure 8Taking the first resource set and the second resource set shown as an example. The network device does not configure the receiving parameters of CSI-RS resource#1, but only configures the receiving parameters of CSI-RS resource#2. The terminal device measures the signal strengths on CSI-RS resource#1, CSI-RS resourc#2, and CSI-RS resource#10 using the same receiving parameter (i.e., the receiving parameter of CSI-RS resource#2).

[0210] For another example, taking Figure 8 the first resource set and the second resource set shown as an example. The network device does not configure the receiving parameters of CSI-RS resource#2, but only configures the receiving parameters of CSI-RS resource#1. The terminal device measures the signal strengths on CSI-RS resource#1, CSI-RS resourc#2, and CSI-RS resource#10 using the same receiving parameter (i.e., the receiving parameter of CSI-RS resource#1).

[0211] In a possible implementation, the configuration information is also used to configure the receiving parameters of N first resources. Based on this possible implementation, the terminal device can perform signal measurements on N first resources and the second resource using the same receiving parameter (i.e., the receiving parameters of the configured N first resources).

[0212] For example, taking Figure 8 the first resource set and the second resource set shown as an example. The network device configures the receiving parameters of CSI-RS resource#2 and CSI-RS resource#1, and ensures that the receiving parameters of CSI-RS resource#2 and CSI-RS resource#1 are the same. The terminal device measures the signal strengths on CSI-RS resource#1, CSI-RSresourc#2, and CSI-RS resource#10 using the same receiving parameter (i.e., the receiving parameters of CSI-RS resource#1 and CSI-RS resource#2).

[0213] In a possible implementation, the configuration information is also used to configure the receiving parameters of the second resource. Based on this possible implementation, the terminal device can perform signal measurements on N first resources and the second resource using the same receiving parameter (i.e., the receiving parameters of the configured second resource).

[0214] For example, taking Figure 8Take the first resource set and the second resource set shown as an example. The network device configures the reception parameters of CSI-RS resource #10. The terminal device measures the signal strengths on CSI-RS resource #1, CSI-RS resource #2, and CSI-RS resource #10 using an identical reception parameter (i.e., the reception parameter of CSI-RS resource #10).

[0215] In a possible implementation, the network device does not configure the reception parameters of the first resource and the second resource, and the terminal device independently uses an identical reception parameter to perform signal measurement on N first resources and the second resource.

[0216] For example, the network device does not configure the reception parameters of CSI-RS resource #1, CSI-RS resource #2, and CSI-RS resource #10, and the terminal device independently uses an identical reception parameter to measure the signal strengths on CSI-RS resource #1, CSI-RS resource #2, and CSI-RS resource #10.

[0217] Please refer to Figure 19 , Figure 19 which is a schematic flowchart of another information reporting method provided by an embodiment of this application. As Figure 19 shown, this information reporting method includes the following steps 1901 to step 1907. Among them:

[0218] 1901. The network device sends configuration information to the terminal device. The configuration information is used to configure a first resource set and a second resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement, and the resources corresponding to the resource identifiers in the second resource set are used for interference measurement. The first resource set includes the identifiers of N first resources, and the second resource set includes the identifiers of N second resources. The identifiers of the N first resources and the identifiers of the N second resources are in one-to-one correspondence. N is an integer greater than 1. Among them: If the configuration information is also used to configure a third resource, and the third resource is associated with the first resource set, and the third resource is a resource for a zero-power reference signal for interference measurement, then the reception parameters of the N first resources are the same.

[0219] Among them, the first resource set can be a non-zero power CSI-RS resource set for channel measurement. The second resource set can be a non-zero power CSI-RS resource set for interference measurement. The third resource can be a zero power CSI-RS resource for interference measurement. For L1-SINR measurement, in the existing protocol, it is stipulated that a non-zero power CSI-RS resource set for channel measurement can also correspond to a zero power CSI-RS resource for interference measurement. The standard text is as follows: When three Resource Settings are configured, the first one Resource Setting (given by higher layer parameter resourcesForChannelMeasurement) is for channel measurement on SSB or NZP CSI-RS. The second one (given by either higher layer parameter csi-IM-ResourcesForInterference) is for interference measurement performed on CSI-IM, where each NZP CSI-RS resource set for channel measurement is associated with one CSI-IM resource for interference measurement. The Third one (given by higher layer parameter nzp-CSI-RS-ResourcesForInterference) is for interference measurement performed on 1 port NZP CSI-RS with density 3REs / RB (that is, if three resource settings are configured, the first resource setting (configured by the channel measurement resource parameter (parameter resourcesForChannelMeasurement)) is for channel measurement based on SSB or non-zero power CSI-RS. The second resource setting (configured by the interference measurement CSI-IM resource parameter (csi-IM-ResourcesForInterference)) is for interference measurement using CSI-IM, where each non-zero power CSI-RS resource set for channel measurement is associated with one CSI-IM resource for interference measurement.The third resource configuration (configured by the interference measurement non-zero power CSI-RS resource parameters) is for interference measurement based on non-zero NZP CSI-RS with a single port density of 3 REs / RB.).

[0220] In a possible implementation, the reception parameters of the N first resources being the same can also be expressed as: the reception parameters of the N first resources are quasi-co-located (QCL). Alternatively, if the first resource set is a non-zero power CSI-RS resource set for channel measurement, the reception parameters of the N first resources being the same can also be expressed as: all the non-zero power CSI-RS resources in each non-zero power CSI-RS resource set for channel measurement are QCL with respect to the 'QCL-TypeD' parameter (the NZP CSI-RS resources in each NZP CSI-RS resource set for channel measurement are QCLed with respect to ‘QCL-TypeD).

[0221] In a possible implementation, if the configuration information is also used to configure the third resource, the configuration information is also used to indicate that the reception parameters of the N first resources are the same. Based on this possible implementation, the network device can indicate to the terminal device that the reception parameters of the N first resources are the same. Alternatively, the terminal device can also determine whether the reception parameters of the N first resources are the same based on whether the configuration information configures the third resource.

[0222] 1902. The network device sends a first reference signal on the first resource.

[0223] In the embodiments of this application, after the network device sends the configuration information, it sends a first reference signal on the first resource.

[0224] 1903. The network device sends a second reference signal on the second resource.

[0225] In the embodiments of this application, after the network device sends the configuration information, it sends a second reference signal on the first resource.

[0226] 1904. The terminal device measures the signal strength on the first resource to obtain a first signal strength.

[0227] In the embodiments of this application, after the terminal device receives the configuration information, it measures the signal strength on the first resource to obtain a first signal strength.

[0228] 1905. The terminal device measures the signal strength on the second resource to obtain a second signal strength.

[0229] In the embodiments of the present application, after the terminal device receives the configuration information, it measures the signal strength on the second resource to obtain the second signal strength.

[0230] 1906. The terminal device measures the interference strength on the third resource to obtain the first interference strength.

[0231] In the embodiments of the present application, after the terminal device receives the configuration information, it measures the interference strength on the third resource to obtain the first interference strength.

[0232] 1907. The terminal device reports one or more first signal-to-interference-plus-noise ratios (SINRs) to the network device. The first SINR is the SINR obtained based on the first signal strength, the second signal strength, and the first interference strength.

[0233] For example, the first signal strength is P1, the second signal strength is P11, and the first interference strength is P12. The terminal device can obtain SINR1 = P1 / (P11 + P12 + N1). The terminal device reports SINR1 to the network device.

[0234] Again, for example, there are multiple first signal strengths, which are P1 and P2 respectively. The second signal strength is P11, and the first interference strength is P12. The terminal device can obtain SINR1 = P1 / (P11 + P12 + N1) and SINR2 = P2 / (P11 + P12 + N1). The terminal device reports SINR1 and / or SINR2 to the network device.

[0235] In Figure 19 In the method described above, the third resource is used to measure interference through the reception parameters of the first resource. Since there is only one third resource, making the reception parameters of N first resources the same is beneficial for the terminal device to successfully measure interference on the zero-power reference signal resource through the reception parameters of the first resource.

[0236] In a possible implementation, the identifiers of the N first resources in the first resource set may be the same or different, that is, the N first resources may be the same resource or different resources.

[0237] In a possible implementation, the identifiers of the N second resources in the second resource set may be the same or different, that is, the N second resources may be the same resource or different resources.

[0238] In a possible implementation, the reception parameters of the N second resources, the reception parameters of the N first resources, and the reception parameters of the third resource are the same. Or, it can be expressed as: the reception parameters of the N second resources, the reception parameters of the N first resources, and the reception parameters of the third resource are quasi-co-located (QCL). Or, if the identifiers of the N first resources in the first resource set are the same (i.e., the N first resources are one resource), it can also be expressed as: the reception parameters of the N second resources, the reception parameters of the first resource, and the reception parameters of the third resource are the same. Or, if the identifiers of the N second resources in the second resource set are the same (i.e., the N second resources are one resource), it can also be expressed as: the reception parameters of the second resource, the reception parameters of the N first resources, and the reception parameters of the third resource are the same.

[0239] By implementing this possible implementation, the interference situation of the transmission parameters of the second resource on the transmission parameters and / or reception parameters of the first resource can be accurately measured.

[0240] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources among the N first resources. Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of one or more resources among the configured N first resources) to perform signal measurement on the first resource and the second resource, and perform interference measurement on the third resource.

[0241] In a possible implementation, the configuration information is further used to configure the reception parameters of the N first resources. Based on this implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of the configured N first resources) to perform signal measurement on the first resource and the second resource, and perform interference measurement on the third resource. If the identifiers of the N first resources in the first resource set are the same, it can also be expressed as: the configuration information is further used to configure the reception parameters of the first resource.

[0242] In a possible implementation, the configuration information is further used to configure the reception parameters of one or more resources in the second resource. Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of one or more resources in the configured second resource) to perform signal measurement on the first resource and the second resource, and perform interference measurement on the third resource.

[0243] In a possible implementation, the configuration information is further used to configure the reception parameters of the N second resources. Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of the configured N second resources) to perform signal measurement on the first resource and the second resource, and perform interference measurement on the third resource. If the identifiers of the N second resources in the second resource set are the same, it can also be expressed as: the configuration information is further used to configure the reception parameters of the second resource.

[0244] In a possible implementation, the configuration information is further used to configure the reception parameters of the third resource. Based on this possible implementation, the terminal device can use the same reception parameters (i.e., the reception parameters of the configured third resource) to perform signal measurements on the first resource and the second resource, and perform interference measurements on the third resource.

[0245] In a possible implementation, the identifiers of the N second resources in the second resource set are the same, and the reception parameters of the second resource are the same as those of the N first resources. The specific implementation manner of measuring the signal strength on the second resource to obtain the second signal strength is: measuring the signal strength on the second resource once to obtain a second signal strength. Based on this possible implementation manner, the terminal can use the same reception parameters to measure multiple first resources and one second resource, which is beneficial to reducing the measurement burden of the terminal device and reducing the communication overhead of the network device.

[0246] In a possible implementation, the configuration information is further used to configure the reception parameters of the third resource. Based on this possible implementation manner, the terminal can use the same reception parameters to measure multiple first resources and one second resource, which is beneficial to reducing the measurement burden of the terminal device and reducing the communication overhead of the network device.

[0247] In a possible implementation, the reception parameters of the N first resources are different, and the period of the third resource can be 1 / N times the period of the first resource. The third resource is used to measure interference through the reception parameters of the first resource. Since there is only one third resource, making the period of the third resource 1 / N times the period of the first resource is beneficial for the terminal device to successfully measure interference on the zero-power reference signal resource through the reception parameters of the first resource.

[0248] In a possible implementation, the reception parameters of the N first resources are different, the period of the third resource is the same as the period of the first resource, and the time domain range for measuring the interference intensity of the N third resources is less than or equal to the time length of one time unit. The third resource is used to measure interference through the reception parameters of the first resource. Since there is only one third resource, when the period of the third resource is the same as the period of the first resource, making the time domain range for measuring the interference intensity of the N third resources less than or equal to the time length of one time unit is beneficial for the terminal device to successfully measure interference on the zero-power reference signal resource through the reception parameters of the first resource.

[0249] In a possible implementation, Figure 4 、 Figure 7 、 Figure 10 and Figure 18 The method described by Figure 19 can be combined with the method described by

[0250] The following is a description of another method for saving the overhead of CMR resources in combination with Figure 10 :

[0251] Please refer to Figure 10 , Figure 10 which is a schematic flowchart of an information reporting method provided by an embodiment of the present application. As Figure 10 shown, the information reporting method includes the following steps 1001 to 1004. Figure 10 The subject of execution of the method shown can be a network device and a terminal device, or the subject can be a chip in the network device and a chip in the terminal device. Figure 10 Taking the network device and the terminal device as the execution subjects of the method as an example for illustration. The subject of execution of the information reporting method shown in other drawings of the embodiments of the present application is the same by analogy, and will not be elaborated hereinafter. Among them:

[0252] 1001. The network device sends configuration information to the terminal device.

[0253] Among them, the configuration information is used to configure a first resource set. The resources corresponding to the resource identifiers in the first resource set are used for channel measurement. The first resource set includes the identifiers of N first resources, and the identifiers of the N first resources are the same. N is an integer greater than 1. Since the first resource set includes the identifiers of N first resources and the identifiers of the N first resources are the same. Therefore, it can be understood that the first resource set includes N identical first resources, or it can be understood that the first resource set includes one first resource.

[0254] For example, as Figure 11 shown, the first resource set is the resource set corresponding to resource set #1 (resourceset#1). Among them, the first resource set includes the identifiers of two identical first resources, and the identifier of the first resource is CSI-RSresource#1.

[0255] Optionally, the configuration information further includes a repetition factor. When the repetition factor is enabled, it means that the transmission parameters of the N first resources are the same transmission parameter. When the repetition factor is disabled, it means that the transmission parameters of the N first resources are not the same transmission parameter. For example, as Figure 11 shown, the repetition factor is repetition. "Repetition: ON" means that the repetition factor is enabled. "Repetition: OFF" means that the repetition factor is disabled. Figure 11 Taking the repetition factor being enabled as an example.

[0256] 1002. The network device sends a reference signal on the first resource.

[0257] In an embodiment of the present application, after the network device sends configuration information to the terminal device, the network device sends a reference signal on a first resource.

[0258] 1003. The terminal device performs N measurements on the signal strength on the first resource to obtain N signal strengths.

[0259] In an embodiment of the present application, after the terminal device receives the configuration information, it performs N measurements on the signal strength on the first resource to obtain N signal strengths.

[0260] Among them, the specific implementation manners for the terminal device to perform N measurements on the signal strength on the first resource include the following two manners:

[0261] Manner 1: The network device uses one transmission parameter to send the reference signal once or N times on the first resource, and then the terminal device uses N different reception parameters to perform N measurements on the signal strength on the first resource.

[0262] For example, as Figure 11 and Figure 12 shown, the repetition factor in the configuration information is enabled. The transmission parameters of both CSI-RS resource #1 are transmission beam a1. The network device sends CSI-RS1 once or twice within one measurement result reporting period through beam a1. The first-ranked CSI-RS resource #1 corresponds to reception beam b1, and the second-ranked CSI-RS resource #1 corresponds to reception beam b2. The terminal device performs the first measurement on CSI-RS1 on the resource corresponding to CSI-RS resource #1 through reception beam b1 to obtain signal strength P1. The terminal device performs the second measurement on CSI-RS1 on the resource corresponding to CSI-RS resource #1 through reception beam b2 to obtain signal strength P2.

[0263] In a possible implementation, the time domain range for the terminal device to perform N measurements is less than or equal to the time length of one time unit, that is, the total duration for the terminal device to perform N measurements is less than or equal to the time length of one time unit. Optionally, one time unit is one OFDM symbol. Or, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Or, the time unit can also be one time slot, one subframe, one millisecond, etc. Or, the time unit can also be two time slots, two subframes, two milliseconds, etc. By implementing this possible implementation manner, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0264] For example, as Figure 12As shown, the network device can send CSI-RS1 once within a measurement result reporting period. The duration for the network device to send CSI-RS1 once is equal to one OFDM. Within one OFDM, the terminal device measures the signal strength of CSI-RS1 twice in total. During the first measurement, the terminal device measures the signal strength of CSI-RS1 through beam b1 and obtains signal strength P1. During the second measurement, the terminal device switches to beam b2 to measure the signal strength of CSI-RS1 and obtains signal strength P2.

[0265] In a possible implementation, the time domain measurement range for each of the N measurements is less than or equal to N IFFT / N, where N IFFT is the time length of one time unit.

[0266] In a possible implementation, the time domain measurement range for each of the N measurements is less than or equal to N IFFT / N - N CP / N, where N CP is the time length of the cyclic prefix, and N IFFT is the time length of one time unit. The cyclic prefix is a guard interval and cannot be used to send reference signals. Therefore, it should be ensured that the time domain measurement range for each of the N measurements is less than or equal to N IFFT / N - N CP / N.

[0267] In a possible implementation, the N measurements are performed after the cyclic prefix. For example, as Figure 13 shown, there can be one cyclic prefix within one time unit, and all N measurements are performed after this cyclic prefix. Another example, as Figure 14 shown, there can be multiple cyclic prefixes within one time unit, and each of the N measurements is performed after one cyclic prefix.

[0268] Method 2: The network device sends the reference signal N times on the first resource using N different transmission parameters. The terminal device can use the same reception parameters to measure the signal strength on the first resource N times.

[0269] For example, assume the repetition factor in the configuration information is off. As Figure 15As shown in the figure, the first-ranked CSI-RS resource #1 corresponds to the transmission beam a1, and the second-ranked CSI-RS resource #1 corresponds to the transmission beam a2. The reception parameters of both CSI-RS resource #1s are the reception beam b1. The terminal device makes a first measurement of the CSI-RS1 transmitted by the beam a1 through the reception beam b1, and obtains the signal strength P1. The terminal device makes a second measurement of the CSI-RS1 transmitted by the beam a2 through the reception beam b1, and obtains the signal strength P2.

[0270] In a possible implementation, the time domain range for the network device to transmit the reference signal N times through N transmission parameters is less than or equal to the time length of one time unit, that is, the total duration for the network device to transmit the reference signal N times through N transmission parameters is less than or equal to the time length of one time unit. Correspondingly, the time domain range for the terminal device to make N measurements is less than or equal to the time length of one time unit, that is, the total duration for the terminal device to make N measurements is less than or equal to the time length of one time unit. Optionally, one time unit is one OFDM symbol. Or, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. By implementing this possible implementation method, it is beneficial to reduce the duration of the measurement result reporting period and beneficial to improve the speed of beam training.

[0271] Again, as Figure 15 shown in the figure, within one OFDM, the network device transmits the CSI-RS1 a total of two times. When transmitting for the first time, the network device transmits the CSI-RS1 through the beam a1. When transmitting for the second time, the network device switches to the beam a2 to transmit the CSI-RS1. Within one OFDM, the terminal device measures the signal strength of the CSI-RS1 a total of two times. When making the first measurement, the terminal device measures the signal strength of the CSI-RS1 transmitted by the beam a1 through the beam b1, and obtains the signal strength P1. When making the second measurement, the terminal device measures the signal strength of the CSI-RS1 through the beam b2, and obtains the signal strength P2.

[0272] In a possible implementation, the time domain range for the network device to transmit the reference signal each time through N transmission parameters is less than or equal to N IFFT / N, where this N IFFT is the time length of one time unit. Correspondingly, in the N measurements of the terminal device, the time domain measurement range of each measurement is less than or equal to N IFFT / N.

[0273] In a possible implementation, the time domain range for the network device to transmit the reference signal each time through N transmission parameters is less than or equal to N IFFT / N - N CP / N, where N CP is the time length of the cyclic prefix, and N IFFT is the time length of a time unit. Accordingly, in the N measurements of the terminal device, the time domain measurement range of each measurement is less than or equal to N IFFT / N - N CP / N.

[0274] In a possible implementation, the network device sends the reference signal N times through N transmission parameters and performs it after the cyclic prefix. Accordingly, the N measurements of the terminal device are performed after the cyclic prefix.

[0275] In a possible implementation, the protocol pre - defines or the network device can also indicate the method for the terminal device to perform N measurements within a time length less than or equal to a time unit. The method includes any one of the following methods: the signal transmission and / or reception method based on Interleaved Frequency Division Multiple Access (IFDMA), the signal transmission and / or reception method with a larger subcarrier spacing, and the signal transmission and / or reception method based on Discrete Fourier Transform (DFT).

[0276] 1004. The terminal device reports the first signal strength among the N signal strengths to the network device.

[0277] In the embodiments of the present application, after the terminal device measures N signal strengths, it reports the first signal strength among the N signal strengths to the network device. The first signal strength can be the minimum value or the maximum value.

[0278] In a possible implementation, when the repetition factor in the configuration information is off, the terminal device also reports the position of the identifier of the first resource corresponding to the first signal strength in the first resource set to the network device. This is beneficial for the network device to determine the transmission parameters used for measuring the first signal strength.

[0279] In a possible implementation, the terminal device can report capability information, and the capability information indicates whether the terminal device supports Figure 10 the method described in the corresponding embodiment.

[0280] In a possible implementation, the protocol pre - defines or the network device can indicate the terminal device to execute Figure 10 the method described in the corresponding embodiment.

[0281] In the existing beam training, different CMR resources are used for training. By implementing Figure 10For the described method, beam training can be performed using the same CMR resources, which helps save the CMR resource overhead.

[0282] In a possible implementation, the present application provides a method for uplink beam training. The method includes: The network device sends configuration information for configuring a first resource set. The resources corresponding to the resource identifiers in the first resource set are used for uplink detection. The first resource set includes identifiers of N first resources, and the identifiers of the N first resources are the same, where N is an integer greater than 1. After receiving the configuration information, the terminal device sends a reference signal on the first resource. After the network device sends the configuration information, it measures the reference signal on the first resource.

[0283] In a possible implementation, the terminal device sending a reference signal on the first resource includes: sending the reference signal N times through N transmission parameters, or sending the reference signal N times through one transmission parameter. The time domain range for the terminal device to send the reference signal N times is less than or equal to the time length of one time unit.

[0284] In a possible implementation, the network device measuring the reference signal on the first resource includes: measuring the reference signal N times through N reception parameters, or measuring the reference signal N times through one reception parameter. Optionally, the time domain range for the network device to measure the reference signal N times is less than or equal to the time length of one time unit.

[0285] Optionally, one time unit is one OFDM symbol. Or, one time unit can also be two OFDM symbols, three OFDM symbols, four OFDM symbols, etc. Or, the time unit can also be one time slot, one subframe, one millisecond, etc. Or, the time unit can also be two time slots, two subframes, two milliseconds, etc.
