Description

Communication method, device and storage medium

[0001] This disclosure claims priority to Chinese patent application No. 202310892593.6, filed on July 19, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method, device, and storage medium. Background Art

[0003] The base station can transmit data using different transmission modes. For example, the base station's antennas can use different spatial filters or precoding matrices. The terminal measures the wireless channel and performs calculations to obtain the spatial filters or precoding matrices, which it then feeds back to the base station. Because the wireless channel is time-varying, the base station needs to adjust its transmission mode to adapt to the channel, for example, switching from one transmission mode to another.

[0004] The greater the terminal's computational workload and the more time and frequency domain resources it uses when feeding back the spatial filter or precoding matrix, the more accurate the spatial filter or precoding matrix obtained by the base station, and thus, the better the transmission performance. Different transmission methods have different acquisition costs, and the more effective ones generally have higher acquisition costs. Therefore, it is necessary to balance the acquisition cost of the transmission method with the effectiveness of the transmission method to determine the appropriate transmission method. Measuring reference signal resources and feeding back the measurement results so that the base station can determine the transmission method with the appropriate transmission performance is a pressing technical issue.

[0033] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0036] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0037] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those stated.

[0038] Wireless channels are time-varying, and base stations must adjust their transmission modes to adapt to the channel, for example, by switching from one transmission mode to another. Switching between transmission modes incurs additional performance losses, such as introducing additional data transmission delays and causing mismatches in scheduling parameters related to data transmission. Switching between different transmission modes incurs different performance costs.

[0039] The base station transmits reference signals using different reference signal resources, indicating that the base station transmits reference signals using different transmission modes. Different transmission methods have different transmission effects. The terminal feeds back the measurement results of different reference signal resources to the base station to reflect the transmission effects of different transmission modes. This, on the one hand, results in different acquisition costs for different transmission modes. On the other hand, the performance loss costs of switching between different transmission modes also vary. Furthermore, feeding back the measurement results of reference signal resources representing different transmission modes by the terminal incurs a significant amount of time and frequency domain resource overhead. Therefore, how to measure reference signal resources and feed back the measurement results so that the base station can determine the transmission mode with the appropriate transmission results is a technical problem that needs to be solved urgently.

[0040] Based on this, embodiments of the present application provide a communication method, apparatus, and storage medium that receive configuration information, obtain measurement results based on the configuration information, and feed back the corresponding measurement results. Since the measurement results are obtained based on the configuration information, that is, the measurement results are obtained based on the reference signal resource set indicated by the base station, and the M reference signal resources included in the reference signal resource set can be understood as the reference signal resources for which the base station needs to obtain measurement results, the measurement results obtained based on the configuration information enable the base station to determine a transmission mode with an appropriate transmission effect.

[0041] The following describes the solutions of the embodiments of the present application with reference to the accompanying drawings.

[0042] The technical solutions provided in the embodiments of the present application can be applied to various mobile communication networks, for example, new radio (NR) mobile communication networks using fifth-generation mobile communication technology (5G), future mobile communication networks, or multiple communication convergence systems, etc., and the embodiments of the present application are not limited to this.

For another example, the first communication node 110 is a first aircraft, the second communication node 120 is a second aircraft, and the first aircraft and the second aircraft communicate via a wireless channel.

[0045] A base station can be any of an evolution nodeB (eNB), a next-generation nodeB (gNB), a transmission and receiving point (TRP), a transmission point (TP), or some other access node. Depending on the size of the service coverage area provided, base stations can be further divided into macro base stations for providing macro cells, micro base stations for providing micro cells (Pico cells), and femto base stations for providing femto cells. With the continuous evolution of wireless communication technology, future base stations may also adopt other names.

[0046] The terminal may be a device with wireless transceiver capabilities, such as a mobile phone, tablet computer, wearable device, vehicle-mounted device, augmented reality (AR) / virtual reality (VR) device, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), etc. The embodiments of the present invention do not limit the specific type of terminal.

[0047] It should be understood that FIG1 is an exemplary structural diagram, and the number of devices included in the communication system shown in FIG1 is not limited. For example, the number of first communication nodes and second communication nodes is not limited. Furthermore, in addition to the devices shown in FIG1 , the communication system shown in FIG1 may also include other devices, which is not limited.

[0048] Next, as shown in FIG2 , an embodiment of the present application provides a communication method, which is applied to a first communication node. The first communication node may be the first communication node 110 shown in FIG1 . The method includes the following steps S101 to S103 .

[0049] S101: Receive configuration information.

[0050] In some embodiments, when a second communication node needs to determine a transmission mode that provides appropriate transmission between the second communication node and the first communication node, the second communication node sends configuration information to the first communication node. Accordingly, the first communication node receives the configuration information sent by the second communication node. The second communication node may be the second communication node 120 in the communication system shown in FIG. 1 . For example, the following describes a communication method provided in an embodiment of the present application, taking the first communication node as a terminal and the second communication node as a base station as an example.

[0051] The configuration information is used to configure a reference signal resource set, which includes M reference signal resources, where M is a positive integer. The reference signal resources are used to carry reference signals, and reference signals of different transmission modes can be carried by different reference signal resources.

[0052] As an example, the configuration information is used to indicate an identification number of a reference signal resource set, or is used to indicate an index number of a reference signal resource set. As another example, the configuration information is used to indicate M reference signal resources included in the reference signal resource set.

[0053] In some embodiments, a reference signal resource has an order of arrangement within a reference signal resource set, and the index of the reference signal resource within the reference signal resource set can be determined based on the order of arrangement within the reference signal resource set. The order of arrangement of the reference signal resources within the reference signal resource set can be generated by the first communication node or indicated by order indication information sent by the second communication node. The order indication information can be included in the configuration information described above or in other signaling different from the configuration information, and this is not limited in this embodiment of the present application.

[0054] S102: Obtain a measurement result based on the configuration information.

[0055] In some embodiments, obtaining the measurement result based on the configuration information may involve the first communication node measuring all reference signal resources in the reference signal resource set to obtain measurement values ​​for all reference signal resources in the reference signal resource set, and then using the measurement values ​​of all reference signal resources as the measurement result, or using the measurement values ​​of some reference signal resources among the measurement values ​​of all reference signal resources as the measurement result. Alternatively, the first communication node may measure some reference signal resources in the reference signal resource set to obtain measurement values ​​for some reference signal resources, and then using the measurement values ​​of some reference signal resources as the measurement result.

[0056] Based on this, the measurement result includes measurement values ​​of N first reference signal resources, where the first reference signal resources belong to a reference signal resource set, and N is a positive integer less than or equal to M.

[0057] It should be understood that, when N is a positive integer less than M, the first communication node measures some reference signal resources in the reference signal resource set to obtain a measurement result, or measures all reference signal resources in the reference signal resource set on behalf of the first communication node, and then uses the measurement values ​​of some reference signal resources among the measurement values ​​of all reference signal resources as the measurement result. When N is equal to M, the first communication node measures all reference signal resources in the reference signal resource set to obtain a measurement result.

[0058] Among them, the first reference signal resource can be understood as a reference signal resource that requires feedback of a measurement value, and the measurement value of the reference signal resource may include at least one of the following: reference signal received power, reference signal interference-to-noise ratio, reference signal received strength, and reference signal received quality.

[0059] In some embodiments, step S102 can be implemented as the following steps X1 and X2.

[0060] X1. Determine a second reference signal resource based on the configuration information.

[0061] The second reference signal resource may be called by other names, such as a specific reference signal resource or a target reference signal resource.

[0062] In some embodiments, the second reference signal resource is determined according to an arrangement order associated with the M reference signal resources.

[0063] As an example, the arrangement order of the M reference signal resources includes at least one of the following:

[0064] The arrangement order of the M reference signal resources in the reference signal resource set;

[0065] The arrangement order of the M reference signal resources in the time domain;

[0066] The order in which the measurement values ​​of the M reference signal resources are arranged.

[0067] As a possible example, the second reference signal resource is a reference signal resource at a preset position in the arrangement sequence of the M reference signal resources, wherein the preset position includes the first position, the last position, the Kth position, etc.

[0068] Taking the example of determining the second reference signal resource based on the order in which M reference signal resources are arranged in a reference signal resource set, for example, the reference signal resource that ranks first in the order in which the M reference signal resources are arranged in the reference signal resource set can be determined as the second reference signal resource. For another example, the reference signal resource that ranks last in the order in which the M reference signal resources are arranged in the reference signal resource set can be determined as the second reference signal resource. For another example, the reference signal resource that ranks Kth in the order in which the M reference signal resources are arranged in the reference signal resource set can be determined as the second reference signal resource. K can be a non-negative integer preset by the protocol or indicated by the second communication node, and the order in which the M reference signal resources are arranged in the reference signal resource set can be a fixed order.

[0069] Taking the example of determining the second reference signal resource based on the order of M reference signal resources in the time domain, for example, the reference signal resource ranked first in the order of the M reference signal resources in the time domain can be determined as the second reference signal resource. For another example, the reference signal resource ranked last in the order of the M reference signal resources in the time domain can be determined as the second reference signal resource. For another example, the reference signal resource ranked Kth in the order of the M reference signal resources in the time domain can be determined as the second reference signal resource. The order of the M reference signal resources in the time domain can be understood as the temporal order of the M reference signal resources, and the order of the M reference signal resources in the time domain can be a fixed order in the time domain.

[0070] Taking the example of determining the second reference signal resource based on the order of the measurement values ​​of M reference signal resources, for example, the reference signal resource ranked first in the order of the measurement values ​​of the M reference signal resources can be determined as the second reference signal resource. For another example, the reference signal resource ranked last in the order of the measurement values ​​of the M reference signal resources can be determined as the second reference signal resource. For another example, the reference signal resource ranked Kth in the order of the measurement values ​​of the M reference signal resources can be determined as the second reference signal resource. The order of the measurement values ​​of the M reference signal resources can be understood as the order of the measurement values ​​of the M reference signal resources in the reference signal resource set. The order of the measurement values ​​of the M reference signal resources can be a fixed order.

[0071] As another possible example, the second reference signal resource is a reference signal resource indicated by the second communication node.

[0072] In some embodiments, before obtaining the measurement result, the first communication node receives first indication information sent by the second communication node, where the first indication information is used to indicate a position of the second reference signal resource in the arrangement sequence. After receiving the first indication information, the first communication node may determine the position of the second reference signal resource in the arrangement sequence based on the first indication information.

[0073] The first indication information may be included in the above-mentioned configuration information, or may be included in other signaling different from the configuration information, such as the first signaling, and this embodiment of the present application does not impose any restrictions on this.

[0074] For example, taking the arrangement order of M reference signal resources in a reference signal resource set as an example, one way to indicate the position of the second reference signal resource in the arrangement order is to indicate the sequence number of the second reference signal resource in the arrangement order in the reference signal resource set. Alternatively, another way to indicate the position of the second reference signal resource in the arrangement order is a bit map, where each bit maps to a sequence position, and the bit state of a bit is used to indicate whether the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource. For example, when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource, and when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource. For another example, when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource, and when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource.

[0075] For another example, taking the arrangement order of M reference signal resources in the time domain as an example, one way to indicate the position of the second reference signal resource in the arrangement order is to indicate the sequence number of the second reference signal resource in the time domain arrangement order. Alternatively, another way to indicate the position of the second reference signal resource in the arrangement order is a bit map, where each bit maps to a sequence position, and the bit state of a bit is used to indicate whether the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource. For example, when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource; when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource. For another example, when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource; when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource.

[0076] For another example, taking the arrangement order of the measurement values ​​of M reference signal resources as an example, one way to indicate the position of the second reference signal resource in the arrangement order is to indicate the sequence number of the second reference signal resource in the arrangement order of the measurement values ​​of the M reference signal resources. Alternatively, another way to indicate the position of the second reference signal resource in the arrangement order is a bit map, where each bit maps to a sequence position, and the bit state of a bit is used to indicate whether the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource. For example, when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource; when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource. For another example, when the bit state of a bit is 1, it indicates that the reference signal resource corresponding to the sequence position of the bit map is the second reference signal resource; when the bit state of a bit is 0, it indicates that the reference signal resource corresponding to the sequence position of the bit map is not the second reference signal resource.

[0077] For another example, the first indication information indicates an index number of the second reference signal resource in the reference signal resource set. For another example, the first indication information indicates an identification number of the second reference signal resource.

[0078] X2. Obtain measurement values ​​of N first reference signal resources based on the second reference signal resource.

[0079] As an example, obtaining measurement values ​​of N first reference signal resources based on the second reference signal resource may include at least one of the following Examples 1 to 10.

[0080] Example 1: The N measurement values ​​of the first reference signal resources include: the highest N measurement values ​​among the measurement values ​​of the M reference signal resources excluding the measurement value of the second reference signal resource.

[0081] That is, with the measurement value of the second reference signal resource as a reference, the measurement values ​​of the N reference signal resources with the highest measurement values ​​excluding the measurement value of the second reference signal resource are determined from the measurement values ​​of the M reference signal resources as the measurement values ​​of the N first reference signal resources.

[0082] For example, taking the second reference signal resource as the first in the arrangement order of the reference signal resource set, the measurement values ​​of the N reference signal resources with the highest measurement values ​​are correspondingly determined from the reference signal resources other than the first reference signal resource as the measurement values ​​of the N first reference signal resources. For another example, taking the second reference signal resource as the Kth reference signal resource in the arrangement order of the reference signal resource set, the measurement values ​​of the N reference signal resources with the highest measurement values ​​are correspondingly determined from the reference signal resources other than the Kth reference signal resource as the measurement values ​​of the N first reference signal resources. K and N may be indicated by the same signaling or the same configuration information; K and N may also be indicated by different signaling or different configuration information.

[0083] Example 2: The measurement values ​​of the N first reference signal resources include: measurement values ​​that do not exceed a target number of measurement values ​​of the M reference signal resources and are greater than the measurement value of the second reference signal resource.

[0084] The target number may be pre-set by the protocol or indicated by the second communication node, and this embodiment of the present application does not impose any restrictions on this.

[0085] Taking the target number represented by Q as an example, for example, with the measurement value of the second reference signal resource as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value of the second reference signal resource, and no more than Q measurement values ​​that are greater than the measurement value of the second reference signal resource are used as the measurement values ​​of the N first reference signal resources. Based on the relationship between the number Z of measurement values ​​of the M reference signal resources that are greater than the measurement value of the second reference signal resource and Q, Example 2 may include the following four cases.

[0086] Case 1: Z is greater than Q.

[0087] Corresponding to case 1, one approach is to determine Q measurement values ​​greater than the measurement value of the second reference signal resource from among the Z measurement values ​​as the measurement values ​​of the N first reference signal resources. Another approach is to determine L measurement values ​​greater than the measurement value of the second reference signal resource from among the Z measurement values ​​as the measurement values ​​of the N first reference signal resources, where L is a positive integer less than Q. Another approach is to determine one measurement value greater than the measurement value of the second reference signal resource as the measurement value of the N first reference signal resources, when Q is equal to 1.

[0088] Case 2: Z equals Q.

[0089] Corresponding to case 2, one approach is to determine Z measurement values ​​greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources. Another approach is to determine L measurement values ​​greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources, corresponding to Q being greater than 1. Another approach is to determine 1 measurement value greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources, corresponding to Q being equal to 1.

[0090] Case 3: Z is less than Q and greater than 0.

[0091] Corresponding to case 3, Z measurement values ​​greater than the measurement value of the second reference signal resource are determined as the measurement values ​​of the N first reference signal resources.

[0092] Case 4: Z is equal to 0.

[0093] Corresponding to case 4, one approach is to feed back the measurement value of the reference signal resource that does not meet the conditions, and another approach is to determine the N measurement values ​​closest to the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources.

[0094] The following describes several situations in Example 2 with reference to a specific example.

[0095] For example, for case 1, assuming Z=10, when Q=9, one approach is to determine 9 measurement values ​​out of 10 that are greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources.

[0096] Another approach is, corresponding to Q being greater than 1, when Q=9, L measurement values ​​greater than the measurement value of the second reference signal resource are determined from 10 as the measurement values ​​of the N first reference signal resources, where L can be any positive integer between 1 and 8. For example, L=8, which means that 8 measurement values ​​greater than the measurement value of the second reference signal resource are determined from 10 as the measurement values ​​of the N first reference signal resources. Another approach is, corresponding to Q being equal to 1, 1 measurement value greater than the measurement value of the second reference signal resource is determined as the measurement value of the N first reference signal resources.

[0097] For case 2, assuming Z=10, Q=10, one approach is to determine 10 measurement values ​​greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources.

[0098] Another method is to determine L measurement values ​​greater than the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources, corresponding to Q being greater than 1, where L can be any positive integer between 1 and 9. For example, L=9, that is, 9 measurement values ​​greater than the measurement value of the second reference signal resource are determined from 10 as the measurement values ​​of the N first reference signal resources.

[0099] Another way is, corresponding to Q being equal to 1, determining a measurement value that is greater than the measurement value of the second reference signal resource as the measurement value of the N first reference signal resources.

[0100] For case 3, assuming Z=8 and Q=10, 8 measurement values ​​greater than the measurement value of the second reference signal resource may be determined as the measurement values ​​of the N first reference signal resources.

[0101] In this way, based on the above situations, the number of measurement values ​​of the first reference signal resource among the measurement values ​​of the M reference signal resources does not exceed the target number Q.

[0102] Example 3: The measurement values ​​of the N first reference signal resources include: all measurement values ​​of the M reference signal resources that are greater than the measurement value of the second reference signal resource.

[0103] For example, using the measurement value of the second reference signal resource as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value of the second reference signal resource, and all measurement values ​​greater than the measurement value of the second reference signal resource are used as the measurement values ​​of the N first reference signal resources.

[0104] Example 4: The measurement values ​​of the N first reference signal resources include: measurement values ​​that do not exceed a target number of the measurement values ​​of the M reference signal resources and are greater than or equal to the measurement value of the second reference signal resource.

[0105] For example, taking the measurement value of the second reference signal resource as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value of the second reference signal resource, and no more than Q measurement values ​​that are greater than or equal to the measurement value of the second reference signal are used as the measurement values ​​of the N first reference signal resources.

[0106] For the description of the specific case of using no more than Q measurement values ​​that are greater than or equal to the measurement value of the second reference signal as the measurement values ​​of N first reference signal resources, refer to the description of Cases 1 to 4 in Example 2 above and are not repeated here.

[0107] Example 5: The measurement values ​​of the N first reference signal resources include: a measurement value of the M reference signal resources that is greater than or equal to the measurement value of the second reference signal resource.

[0108] For example, with the measurement value of the second reference signal resource as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value of the second reference signal resource, and the measurement value greater than or equal to the measurement value of the second reference signal resource is used as the measurement value of the N first reference signal resources.

[0109] Example 6: The measurement values ​​of the N first reference signal resources include: the measurement values ​​of the M reference signal resources, excluding the measurement value of the second reference signal resource, which do not exceed the target number and are greater than or equal to the measurement value of the second reference signal resource.

[0110] For example, taking the measurement value of the second reference signal resource as a reference, the measurement values ​​of the M reference signal resources except the measurement value of the second reference signal resource are compared with the measurement value of the second reference signal resource, and the measurement values ​​that do not exceed the target number and are greater than or equal to the measurement value of the second reference signal resource are used as the measurement values ​​of the N first reference signal resources.

[0111] For a description of the specific situation of using the measurement values ​​of the M reference signal resources, excluding the measurement value of the second reference signal resource, which do not exceed the target number and are greater than or equal to the measurement value of the second reference signal resource, as the measurement values ​​of the N first reference signal resources, refer to the description of Cases 1 to 4 in Example 2 above and are not repeated here.

[0112] Example 7: The measurement values ​​of the N first reference signal resources include: measurement values ​​that do not exceed the target number and are greater than the measurement value threshold among the measurement values ​​of the M reference signal resources.

[0113] The measurement value threshold is equal to the sum of the measurement value of the second reference signal resource and the offset value. The offset value may be pre-set by the protocol and may be indicated by configuration information sent by the second communication node, the first signaling, or the second signaling, where the second signaling is different from the first signaling.

[0114] For example, with the measurement value threshold as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value threshold, and no more than Q measurement values ​​that are greater than the measurement value threshold are used as the measurement values ​​of the N first reference signal resources. Based on the relationship between the number Y of measurement values ​​greater than the measurement value threshold and Q among the measurement values ​​of the M reference signal resources, Example 7 may include the following four cases.

[0115] Case 1: Y is greater than Q.

[0116] For case 1, one approach is to determine Q measurement values ​​greater than a measurement value threshold from Y as the measurement values ​​of the N first reference signal resources. Another approach is to, when Q is greater than 1, determine L measurement values ​​greater than the measurement value threshold from Y as the measurement values ​​of the N first reference signal resources. Another approach is to, when Q is equal to 1, determine one measurement value greater than the measurement value threshold as the measurement value of the N first reference signal resources.

[0117] Case 2: Y equals Q.

[0118] For case 2, one approach is to determine Q measurement values ​​greater than a measurement value threshold as the measurement values ​​of the N first reference signal resources. Another approach is to, when Q is greater than 1, determine L measurement values ​​greater than the measurement value threshold as the measurement values ​​of the N first reference signal resources. Another approach is to, when Q is equal to 1, determine one measurement value greater than the measurement value threshold as the measurement value of the N first reference signal resources.

[0119] Case 3: Y is less than Q and greater than 0.

[0120] For case 3, L measurement values ​​greater than the measurement value threshold are determined as the measurement values ​​of the N first reference signal resources.

[0121] Case 4: Y is equal to 0.

[0122] For case 4, one approach is to feed back the measurement value of the reference signal resource that does not meet the conditions. Another approach is to determine N measurement values ​​closest to the measurement value of the second reference signal resource as the measurement values ​​of the N first reference signal resources.

[0123] Example 8: The measurement values ​​of the N first reference signal resources include: measurement values ​​that do not exceed the target number and are greater than or equal to the measurement value threshold among the measurement values ​​of the M reference signal resources.

[0124] For example, with the measurement value threshold as a reference, the measurement values ​​of the M reference signal resources, except for the measurement value of the second reference signal resource, are compared with the measurement value threshold, and the measurement values ​​that do not exceed the target number and are greater than or equal to the measurement value threshold are used as the measurement values ​​of the N first reference signal resources.

[0125] For a description of the specific situation of using, in addition to the measurement value of the second reference signal resource among the measurement values ​​of the M reference signal resources, the measurement values ​​that do not exceed the target number and are greater than or equal to the measurement value threshold as the measurement values ​​of the N first reference signal resources, refer to the description of Cases 1 to 4 in Example 7 above and are not repeated here.

[0126] Example 9: The measurement values ​​of the N first reference signal resources include: all measurement values ​​of the M reference signal resources that are greater than the measurement value threshold.

[0127] For example, with the measurement value threshold as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value threshold, and all measurement values ​​of the M reference signal resources that are greater than the measurement value threshold are used as the measurement values ​​of the N first reference signal resources.

[0128] Example 10: The measurement values ​​of the N first reference signal resources include: measurement values ​​greater than or equal to a measurement value threshold among the measurement values ​​of the M reference signal resources.

[0129] For example, using a measurement value threshold as a reference, the measurement values ​​of the M reference signal resources are compared with the measurement value threshold, and the measurement values ​​of the M reference signal resources that are greater than or equal to the measurement value threshold are used as the measurement values ​​of the N first reference signal resources. It should be understood that, compared to Example 9 above, Example 10 also uses the measurement values ​​of the M reference signal resources that are equal to the measurement value threshold as the measurement values ​​of the first reference signal resources.

[0130] It should be noted that, those skilled in the art may select any of the above methods to determine the second reference signal resource and the measurement values ​​of N first reference signal resources according to actual application scenarios, and the embodiments of the present application do not limit this.

[0131] In the above embodiment, the second reference signal resource is used as a reference to obtain the measurement values ​​of the N first reference signal resources.

[0132] In some embodiments, the first communication node may further receive second indication information sent by the second communication node, and further determine N first reference signal resources based on the second indication information to obtain measurement values ​​of the N first reference signal resources. The second indication information is used to indicate the N first reference signal resources. The second indication information may be included in the configuration information described above, or in signaling different from the configuration information described above, such as the first signaling, the second signaling, or a third signaling different from the first signaling and the second signaling, without limitation.

[0133] In some embodiments, the second indication information includes a value of N, that is, the second indication information indicates that the first communication node needs to feed back measurement values ​​of N first reference signal resources.

[0134] As an example, the N first reference signal resources include one of the following: the first N reference signal resources in the arrangement order related to the M reference signal resources; the last N reference signal resources in the arrangement order related to the M reference signal resources; the first N reference signal resources in the arrangement order related to reference signal resources other than the second reference signal resource among the M reference signal resources; the last N reference signal resources in the arrangement order related to reference signal resources other than the second reference signal among the M reference signal resources; the X reference signal resources before the second reference signal resource, and the NX reference signal resources after the second reference signal resource, in the arrangement order related to the M reference signal resources, where X is an integer less than or equal to N and greater than or equal to 0.

[0135] In some embodiments, the arrangement order related to other reference signal resources may include one of the following: the arrangement order of other reference signal resources in the reference signal resource set; the arrangement order of other reference signal resources in the time domain; and the arrangement order of measurement values ​​of other reference signal resources.

[0136] Among them, the arrangement order of other reference signal resources in the reference signal resource set can be determined by the first communication node, or can be indicated by the configuration information sent by the second communication node or other signaling different from the configuration information. The embodiment of the present application does not limit this.

[0137] For the description of the arrangement order related to other reference signal resources, reference may be made to the above description of the arrangement order related to the M reference signal resources, and will not be repeated here.

[0138] In some embodiments, when the number of M reference signal resources included in the reference signal resource set is large, candidate first reference signal resources can also be determined based on the arrangement order of the M reference signal resources, and then N first reference signal resources can be determined from the candidate first reference signal resources.

[0139] As a possible example, when the arrangement order associated with the M reference signal resources is the arrangement order of the M reference signal resources in the reference signal resource set, the reference signal resources at even-numbered positions in the arrangement order can be determined as candidate first reference signal resources, or the reference signal resources at odd-numbered positions in the arrangement order can be determined as candidate first reference signal resources. Furthermore, N first reference signal resources are determined from the candidate first reference signal resources.

[0140] As another possible example, when the arrangement order related to the M reference signal resources is the arrangement order of the measurement values ​​of the M reference signal resources, the reference signal resource at an even-numbered arrangement position in the arrangement order can be determined as a candidate first reference signal resource, or the reference signal resource at an odd-numbered arrangement position in the arrangement order can be determined as a candidate first reference signal resource.

[0141] In some embodiments, N first reference signal resources may be determined according to the arrangement order and the predefined pattern positions, or candidate first reference signal resources may be determined.

[0142] In some embodiments, the index number of the reference signal resource can be used as input, calculated according to a predetermined function, or according to a preset lookup table, and the reference signal resources whose results meet the conditions can be used as N first reference signal resources, or determined as candidate first reference signal resources.

[0143] As another possible example, when the arrangement order related to the M reference signal resources is the arrangement order of the M reference signal resources in the time domain, the ranking number of the reference signal resource in the arrangement order can be used as input, and calculated according to a predetermined function, or according to a preset lookup table, the reference signal resources whose results meet the conditions can be used as the N first reference signal resources.

[0144] As another example, N first reference signal resources can be determined based on the third indication information sent by the second communication node. The third indication information is used to indicate the order of arrangement of the N first reference signal resources in the time domain within the reference signal resource set. For example, the reference signal resource corresponding to the sorting number in the time domain within the reference signal resource set indicated by the third indication information can be used as the first reference signal resource. For another example, the reference signal resource indicated by the second communication node in a bit map is used as the first reference signal resource. In the bit map, one bit corresponds to one reference signal resource, or to a group of reference signal resources, and the bits from low to high correspond to the reference signal resources or reference signal resource groups from first to last in the time domain.

[0145] In some embodiments, the bit state of a bit is used to indicate whether the reference signal resource mapped to the bit is the first reference signal resource. For example, when the bit state of a bit is 0, it indicates that the reference signal resource mapped to the bit is the first reference signal resource, and when the bit state of a bit is 1, it indicates that the reference signal resource mapped to the bit is not the first reference signal resource. For another example, when the bit state of a bit is 1, it indicates that the reference signal resource mapped to the bit is the first reference signal resource, and when the bit state of a bit is 0, it indicates that the reference signal resource mapped to the bit is not the first reference signal resource.

[0146] In some embodiments, the bit state of a bit may also be used to indicate whether the reference signal resource mapped to the bit is a candidate first reference signal resource. For example, when the bit state of a bit is 0, it indicates that the reference signal resource mapped to the bit is a candidate first reference signal resource, and when the bit state of a bit is 1, it indicates that the reference signal resource mapped to the bit is not a candidate first reference signal resource. For another example, when the bit state of a bit is 1, it indicates that the reference signal resource mapped to the bit is a candidate first reference signal resource, and when the bit state of a bit is 0, it indicates that the reference signal resource mapped to the bit is not a candidate first reference signal resource.

[0147] As another example, N first reference signal resources can be determined based on the measurement values ​​of M reference signal resources. Exemplarily, the N first reference signal resources may also include one of the following: reference signal resources whose measurement values ​​are greater than a first threshold among the M reference signal resources; reference signal resources whose measurement values ​​are greater than or equal to the first threshold among the M reference signal resources; reference signal resources whose measurement values ​​are less than a second threshold among the M reference signal resources; reference signal resources whose measurement values ​​are less than or equal to the second threshold among the M reference signal resources; reference signal resources whose measurement values ​​are greater than the first threshold and less than the second threshold among the M reference signal resources; reference signal resources whose measurement values ​​are greater than the first threshold and less than or equal to the second threshold among the M reference signal resources; reference signal resources whose measurement values ​​are greater than or equal to the first threshold and less than the second threshold among the M reference signal resources; reference signal resources whose measurement values ​​are greater than or equal to the first threshold and less than the second threshold among the M reference signal resources. Among them, the second threshold is greater than the first threshold, and the first threshold and the second threshold may be pre-set by the protocol or indicated by the second communication node, and this embodiment of the application does not limit this.

[0148] In some embodiments, reference signal resources among the M reference signal resources whose measurement values ​​are greater than a first threshold may also be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are greater than or equal to the first threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are less than a second threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are less than or equal to the second threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are greater than the first threshold and less than the second threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are greater than the first threshold and less than or equal to the second threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are greater than or equal to the first threshold and less than the second threshold may be used as candidate first reference signal resources; or, reference signal resources among the M reference signal resources whose measurement values ​​are greater than or equal to the first threshold and less than the second threshold may be used as candidate first reference signal resources. After determining the candidate first reference signal resources based on any of the above methods, N first reference signal resources may be determined from the candidate first reference signal resources.

[0149] It should be noted that, those skilled in the art may select any of the above methods to determine the N first reference signal resources according to actual application scenarios, and the embodiments of the present application do not limit this.

[0150] After determining the N first reference signal resources by any of the above methods, the first communication node may measure the N first reference signal resources to obtain measurement values ​​of the N first reference signal resources; or obtain measurement values ​​of the N first reference signal resources if measurement values ​​already exist.

[0151] S103: Send the measurement result.

[0152] It should be understood that the second communication node transmitting the reference signal using different reference signal resources represents transmitting the reference signal using different transmission modes, and different transmission modes have different transmission effects. The first communication node sends the measurement result to the second communication node to provide feedback to the second communication node on the measurement results of the different reference signal resources, reflecting the transmission effects of the different transmission modes, so that the second communication node can determine, based on the measurement results, a transmission mode that achieves an appropriate transmission effect between the second communication node and the first communication node.

[0153] In some embodiments, the measurement result may include the measurement values ​​of all reference signal resources in the reference signal resource set, or the measurement values ​​of some reference signal resources in the reference signal resource set, or the measurement values ​​of all measured reference signal resources in the reference signal resource set, or the measurement values ​​of some measured reference signal resources among the measured reference signal resources in the reference signal resource set, or the measurement value of the first reference signal resource in the feedback reference signal resource set.

[0154] As an example, sending the measurement result may include sending the measurement values ​​of the N first reference signal resources according to the arrangement order of the N first reference signal resources in the time domain. In this way, the second communication node can analyze the measurement values ​​of the N first reference signal resources in an orderly manner based on the arrangement order of the N first reference signal resources in the time domain to determine a transmission mode with an appropriate transmission effect.

[0155] As another example, sending the measurement result may be sending the measurement values ​​of the N first reference signal resources in the order of arrangement of the measurement values ​​of the N first reference signal resources. The order of arrangement of the measurement values ​​of the N first reference signal resources may be positively correlated with or negatively correlated with the magnitude of the measurement values ​​of the N first reference signal resources, and this is not limited in the embodiments of the present application. It should be understood that sending the measurement values ​​of the N first reference signal resources in the order of arrangement of the measurement values ​​of the N first reference signal resources allows the second communication node to receive the measurement values ​​of the N first reference signal resources in an orderly manner, thereby enabling the second communication node to determine a transmission method with an appropriate transmission effect.

[0156] As another example, sending the measurement result may be sending all measurement values ​​of N first reference signal resources.

[0157] As another example, to reduce feedback overhead for the first communication node, sending the measurement result may include sending a portion of the measurement values ​​of the N first reference signal resources. In this way, since only a portion of the measurement values ​​of the N first reference signal resources are sent, feedback overhead for the first communication node can be reduced.

[0158] It should be noted that the implementation methods corresponding to the above examples can be arranged and combined. For example, part of the measurement values ​​of the N first reference signal resources can be sent according to the arrangement order of the N first reference signal resources in the time domain, etc. The embodiments of the present application are not limited to this.

[0159] In some embodiments, the measurement result may further include the measurement value of the second reference signal resource. Based on this, the measurement result may be transmitted by first transmitting the measurement value of the second reference signal resource and then transmitting the measurement values ​​of the N first reference signal resources. Transmitting the measurement value of the second reference signal resource first and then transmitting the measurement values ​​of the N first reference signal resources can be understood as placing the measurement value of the second reference signal resource first in the transmission order.

[0160] In the case of sending the measurement value of the second reference signal resource, sending the measurement values ​​of the N first reference signal resources may include sending the measurement values ​​of the N first reference signal resources in the order in which the measurement values ​​of the N first reference signal resources are arranged; or sending the measurement values ​​of the N first reference signal resources in the order in which the N first reference signal resources are arranged in the reference signal resource set; or sending the measurement values ​​of the N first reference signal resources in the order in which the N first reference signal resources are arranged in the time domain. This embodiment of the present application is not limited to this.

[0161] In some embodiments, when the first communication node sends the measurement result, or after sending the measurement result, the first communication node may send the index value of the first reference signal resource in the set consisting of N first reference signal resources to the second communication node, so that when the second communication node needs to determine the transmission effect of the transmission mode corresponding to a first reference signal resource, it can quickly determine the first reference signal resource and its measurement value based on the index value of the first reference signal resource in the set, so as to improve the efficiency of the second communication node in determining the transmission mode with appropriate transmission effect.

[0162] The index value of a first reference signal resource in the set of N first reference signal resources may be an index value determined according to the order in which the first reference signal resource is arranged in the reference signal resource set, or an index value determined according to the order in which the first reference signal resource is arranged in the time domain among the M reference signal resources. The index value may also be referred to by other names, such as an index number.

[0163] In some embodiments, the arrangement order of a first reference signal resource in the reference signal resource set may be generated by the first communication node or indicated by the second communication node, and this embodiment of the present application does not impose any limitation on this.

[0164] Based on the embodiment shown in Figure 2, the first communication node receives configuration information, obtains measurement results based on the configuration information, and feeds back the corresponding measurement results. Since the measurement results are obtained based on the configuration information, that is, the measurement results are obtained based on the reference signal resource set indicated by the second communication node, and the M reference signal resources included in the reference signal resource set can be understood as reference signal resources for which the second communication node needs to obtain measurement results, that is, the second communication node indicates the reference signal resources for which the first communication node needs to feed back measurement values ​​through the configuration information, and then, the measurement results obtained by the first communication node from measuring the reference signal resources based on the configuration information are required by the second communication node. In this way, measuring the reference signal resources based on the configuration information of the second communication node enables the second communication node to determine a transmission method with appropriate transmission effect based on the measurement results. Moreover, when sending the measurement results, the first communication node may send part of the measurement values ​​of the N first reference signal resources, thereby reducing the feedback overhead of the first communication node in feeding back the measurement results. Moreover, when sending the measurement results, the first communication node may send the measurement values ​​of the N first reference signal resources according to the arrangement order of the N first reference signal resources in the time domain, or may send the measurement values ​​of the N first reference signal resources according to the arrangement order of the measurement values ​​of the N first reference signal resources, so that the second communication node can receive the measurement values ​​of the N first reference signal resources in an orderly manner, thereby enabling the second communication node to determine a transmission method with an appropriate transmission effect.

[0165] In some embodiments, as shown in FIG3 , an embodiment of the present application provides a communication method, which is applied to a second communication node. The second communication node may be the second communication node 120 shown in FIG1 above. The method includes the following steps S201 and S202 .

[0166] S201: Send configuration information.

[0167] In some embodiments, when a second communication node needs to determine a transmission mode with a first communication node, the second communication node sends configuration information to the first communication node, wherein the configuration information is used to configure a reference signal resource set, where the reference signal resource set includes M reference signal resources, where M is a positive integer.

[0168] S202: Receive measurement results.

[0169] The measurement result includes measurement values ​​of N first reference signal resources, where the first reference signal resources belong to the reference signal resource set, and N is a positive integer less than or equal to M.

[0170] For the description of the measurement results, reference may be made to the corresponding description of the measurement results in the above step S103 , which will not be elaborated here.

[0171] In some embodiments, the measured values ​​of the N first reference signal resources are determined based on the second reference signal resource. For the description of the second reference signal resource, reference may be made to the corresponding description of step S102 above, which will not be repeated here.

[0172] In some embodiments, after sending the configuration information to the first communication node, the second communication node may further send second indication information to the first communication node, where the second indication information is used to indicate N first reference signal resources.

[0173] In some embodiments, after receiving the measurement result, the second communication node may determine, based on the measurement result, a transmission method that has an appropriate transmission effect with the first communication node.

[0174] The above mainly introduces the solution provided by the present application from the perspective of interaction between each node. It is understandable that each node, such as the first communication node or the second communication node, includes a hardware structure and / or software module corresponding to the execution of each function in order to implement the above functions.
