[0026] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0027] 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.

[0028] The terms "first," "second," and the like 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 qualified by the terms "first," "second," and the like may explicitly or implicitly include one or more of such features. Throughout this disclosure, unless otherwise specified, "plurality" means two or more.

[0029] In the embodiments of the present disclosure, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a concrete manner.

[0030] Additionally, the use of “based on” is meant to be open and inclusive, expressing a minimum condition, 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 the stated ones.

[0031] Currently, the process for acquiring channel state information in communication systems is as follows: the base station transmits a reference signal; the terminal receives and measures the reference signal, determines the channel state information from the base station to the terminal, and then reports the channel state information to the base station; after the base station receives the channel state information reported by the terminal, it determines a data transmission strategy based on the received channel state information and transmits data based on the determined data transmission strategy, thereby improving data transmission efficiency. However, wireless channels are time-varying channels. Traditionally, the base station transmits a reference signal once, and the terminal receives and measures the reference signal once. The terminal obtains the channel state information and feeds it back to the base station. The base station uses the channel state information fed back by the terminal to generate a data transmission strategy until the next reference signal transmission brings an update to the data transmission strategy. This may cause the current data transmission strategy to be incompatible with the wireless channel state at the time of data transmission, affecting the performance of the communication system.

[0032] In order to make the data transmission strategy match the wireless channel state when transmitting data, in some technologies, the way to obtain channel state information is that the terminal measures a limited number of reference signals, and the terminal predicts the channel state information at one or more future times in a certain way based on the measurement of the limited number of reference signals, and feeds back the predicted channel state information at one or more future times to the base station, thereby saving the terminal's overhead of reporting the channel state information and reducing the situation where the current data transmission strategy cannot match the wireless channel state when transmitting data due to the delay caused by reporting the channel state information and the time interval for reporting the channel state information.

[0033] However, inaccurate predicted channel state information will affect the performance of the communication system. The terminal monitors the accuracy of the predicted channel state information to ensure its accuracy. For example, if the terminal detects that the predicted channel state information is inaccurate, it can take certain measures, such as switching the channel state information prediction method or adjusting the parameters used in the channel state information prediction method, to ensure the accuracy of the predicted channel state information.

[0034] In some technologies, a terminal monitors predicted channel state information by periodically transmitting a reference signal (RS) at a specific time point. The terminal then measures the RS at the predicted time point to monitor the predicted channel state information. However, this monitoring method increases the resource overhead of the reference signal, reducing communication system performance. Therefore, reducing the resource overhead required for monitoring channel state information is a pressing technical issue.

[0035] Based on this, the embodiments of the present disclosure provide a communication method, device and storage medium. When the base station requires the terminal to monitor the predicted channel state information, or requires the terminal not to monitor or stop the terminal from monitoring the predicted channel state information, the base station instructs the terminal whether to monitor the channel state information included in the channel state information report. Compared with some technologies in which the base station periodically sends a reference signal to enable the terminal to monitor the predicted channel state information, this reduces the resource overhead required for monitoring the channel state information, ensures the accuracy of the acquired channel state information, and helps to improve the performance of the communication system.

[0036] It should be noted that the reference signal sent by the base station to the terminal can be a downlink reference signal. In the long term evolution (LTE) system, the downlink reference signal used for channel state information reporting includes a cell-specific reference signal (CRS) and a channel state information reference signal (CSI-RS); in the new radio (NR) system, the downlink reference signal used for channel state information reporting includes CSI-RS. CSI-RS is carried by a channel state information reference signal resource (CSI-RS Resource), and the channel state information reference signal resource is composed of a code division multiplexing (CDM) group. A CDM group is composed of radio resource elements, and the CSI-RS of a group of CSI-RS ports are multiplexed on the CSI-RS port by code division multiplexing.

[0037] In the LTE wireless technology of the fourth generation mobile communication technology (4G) or the NR wireless technology of the fifth generation mobile communication technology (5G), reference signals are divided into periodic reference signals, semi-persistent reference signals, and aperiodic reference signals according to the transmission method of the reference signals. The base station configures reference signal resources (RS resources) and transmits reference signals on the reference signal resources. The base station configures reference signal resources at multiple levels, one of which is the reference signal scenario (RS setting), which includes at least one reference signal resource set in the reference signal scenario; another level is the reference signal resource set (RS resource set), which includes at least one reference signal resource in the reference signal resource set; and yet another level is the reference signal resource, which specifies the orthogonal frequency division multiplexing (OFDM) symbols and frequency domain locations used for reference signal transmission in the reference signal resource. For periodic reference signals, the base station configures the period and time slot offset of the reference signal resource and then transmits the reference signal on the reference signal resource at the configured time. For semi-persistent reference signals, the base station configures the period and time slot offset of the reference signal resources. When a reference signal needs to be transmitted, the base station first activates the reference signal resource set using media access control (MAC) signaling, and then transmits the reference signal resources on the reference signal resource set at the configured time. When it is necessary to stop transmitting the reference signal, the base station deactivates the reference signal resource set using MAC signaling. For aperiodic reference signals, when a reference signal needs to be transmitted, the base station triggers the reference signal resource set using downlink control information format (DCI Format) signaling, and then transmits the reference signal on the reference signal resources corresponding to the reference signal resource set. The terminal receives the base station's configuration regarding the reference signal and receives the reference signal based on the configuration regarding the reference signal.

[0038] The following describes the solutions of the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0039] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, NR mobile communication networks using 5G, future mobile communication networks (for example, 6G wireless communication systems) or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0040] Figure 1 is a schematic diagram of the structure of a communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the communication system includes, but is not limited to, a first communication node 110 and a second communication node 120. The first communication node 110 and the second communication node 120 can transmit and receive wireless signals and perform related interactions.

[0041] In a wireless communication scenario, a first communication node 110 and a second communication node 120 communicate via a wireless channel. For example, the first communication node 110 is a base station and the second communication node 120 is a terminal, and the base station and the terminal communicate via a wireless channel. In another example, the first communication node 110 is a terminal and the second communication node 120 is a wireless router, and the wireless router and the terminal communicate via a wireless channel.

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

[0043] In some embodiments, the base station may be any of an evolution nodeB (eNB), a next generation nodeB (gNB), a transmission receive point (TRP), a transmission point (TP), and some other access nodes. 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 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.

[0044] 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 disclosure do not limit the type of terminal.

[0045] It should be understood that Figure 1 is an exemplary structural diagram, and the number of devices included in the communication system shown in Figure 1 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 Figure 1, the communication system shown in Figure 1 may also include other devices, which is not limited.

[0046] Next, as shown in FIG2 , an embodiment of the present disclosure 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 S101 .

[0047] S101. Instruct the second communication node whether to monitor the channel state information included in the channel state information report.

[0048] In some embodiments, when a first communication node requires a second communication node to monitor channel state information included in a channel state information report, or requires the second communication node to not monitor or stop monitoring the channel state information included in the channel state information report, the first communication node instructs the second communication node whether to monitor the channel state information included in the channel state information report. The second communication node may be the second communication node 120 shown in FIG. 1 . Exemplarily, the following describes a communication method provided in an embodiment of the present disclosure, taking the first communication node as a base station and the second communication node as a terminal as an example.

[0049] In some implementations, the channel state information included in the channel state information report may refer to channel state information predicted by the second communication node.

[0050] Based on the embodiment shown in Figure 2, the base station can instruct the terminal to monitor the channel state information included in the channel state information report by instructing the terminal whether to monitor the channel state information included in the channel state information report. When the terminal needs to monitor the channel state information included in the channel state information report, the base station can instruct the terminal not to monitor or stop monitoring the channel state information included in the channel state information report when the terminal does not need to monitor the channel state information included in the channel state information report. Compared with some technologies in which the base station periodically sends a reference signal to enable the terminal to monitor the predicted channel state information, this saves computing power overhead, reduces the resource overhead of transmitting reference signals required for monitoring the channel state information, ensures the accuracy of the acquired channel state information, and helps to improve the performance of the communication system.

[0051] In some embodiments, as shown in FIG3 , the above S101 may include the following S201 .

[0052] S201: Send first information to a second communication node. Correspondingly, the second communication node receives the first information sent by the first communication node.

[0053] In some embodiments, when a first communication node requires a second communication node to monitor channel state information included in a channel state information report, or requires the second communication node to not monitor or stop monitoring the channel state information included in the channel state information report, the first communication node sends first information to the second communication node. The first information is used to instruct the second communication node to feed back the channel state information report, and the first information is also used to instruct the second communication node whether to monitor the channel state information included in the channel state information report.

[0054] That is, when the first communication node instructs the second communication node to feed back a channel state information report through the first information, the first communication node may also instruct the second communication node through the first information whether to monitor the channel state information included in the channel state information report. Feedback of a channel state information report may also be referred to by other names, such as transmission of a channel state information report.

[0055] As an example, the first communication node sends the first information to the second communication node, which may be the first communication node sending the first signaling to the second communication node, the first signaling carrying the first information. The first information may be understood as a field in the first signaling, or a domain in the first signaling.

[0056] In some embodiments, the first signaling may be DCI signaling.

[0057] It should be understood that the first communication node sends a first signaling to the second communication node to instruct the second communication node whether to monitor the channel state information included in the channel state information report. This can instruct the terminal to monitor the channel state information included in the channel state information report when the terminal needs to monitor the channel state information included in the channel state information report, and can instruct the terminal not to monitor or stop monitoring the channel state information included in the channel state information report when the terminal does not need to monitor the channel state information included in the channel state information report, thereby saving computing power and helping to reduce the resource overhead of the transmission reference signal required for monitoring the channel state information.

[0058] In some embodiments, the first information is also used to indicate whether the second communication node monitors the channel state information included in the channel state information report, which is related to the value of the first information.

[0059] For example, when the first information takes a first value, the first information is further used to instruct the second communication node to monitor the channel state information included in the channel state information report. For another example, when the first information takes a second value, the first information is further used to instruct the second communication node not to monitor the channel state information included in the channel state information report. It should be understood that not monitoring the channel state information included in the channel state information report includes stopping monitoring the channel state information included in the channel state information report. The first value and the second value can be determined based on bits included in the first information, and the first value is different from the second value.

[0060] In some embodiments, the first information is used to instruct the second communication node to feed back a channel state information report, and the first information is also used to instruct the second communication node whether to monitor the channel state information included in the channel state information report, which is related to the value of the first information.

[0061] For example, the first information includes a first value. When the first information takes the first value, the first information is used to instruct the second communication node to feed back a channel state information report, and the first information is also used to instruct the second communication node not to monitor the channel state information included in the channel state information report.

[0062] For another example, the first information includes a first value and a second value. When the first information takes the first value, the first information is used to instruct the second communication node to feed back a channel state information report, and the first information is also used to instruct the second communication node not to monitor the channel state information included in the channel state information report. When the first information takes the second value, the first information is used to instruct the second communication node to feed back a channel state information report, and the first information is also used to instruct the second communication node to monitor the channel state information included in the channel state information report.

[0063] For another example, the channel state information report includes channel state information report A and channel state information report B, and the first information includes a first value, a second value, a third value, and a fourth value. When the first information takes the first value, the first information is used to instruct the second communication node to feed back channel state information report A, and the first information is also used to instruct the second communication node not to monitor the channel state information A included in the channel state information report. When the first information takes the second value, the first information is used to instruct the second communication node to feed back channel state information report A, and the first information is also used to instruct the second communication node to monitor the channel state information A included in the channel state information report. When the first information takes the third value, the first information is used to instruct the second communication node to feed back channel state information report B, and the first information is also used to instruct the second communication node not to monitor the channel state information B included in the channel state information report. When the first information takes the fourth value, the first information is used to instruct the second communication node to feed back channel state information report B, and the first information is also used to instruct the second communication node to monitor the channel state information B included in the channel state information report.

[0064] It should be understood that instructing the second communication node to feedback a channel state information report and instructing the second communication node whether to monitor the channel state information included in the channel state information report use the same field (domain) or the same value on the same field on the same signaling, which can reduce the signaling overhead and reduce the complexity of the signaling.

[0065] In some embodiments, the first communication node may also use different fields in the first signaling to instruct the second communication node to perform different functions, or to perform operations related to different functions. For example, the first communication node may use the first field of the first signaling to notify the second communication node of scheduling information for data transmission, and use the second field of the first signaling to notify the second communication node of the transmission of a channel state information report. Using the second field of the first signaling to notify the transmission of a channel state information report may include different channel state information reports being triggered by different values ​​in the second field of the first signaling.

[0066] In some embodiments, as shown in FIG4 , before S101 , the method may further include the following S301 .

[0067] S301: Send at least one of first configuration information, second configuration information, and third configuration information to a second communication node. Correspondingly, the second communication node receives at least one of the first configuration information, second configuration information, and third configuration information sent by the first communication node.

[0068] In some embodiments, when a first communication node needs to determine a data transmission strategy that has an appropriate transmission effect with a second communication node, the first communication node configures first configuration information, second configuration information, and third configuration information, and sends at least one of the first configuration information, the second configuration information, and the third configuration information to the second communication node.

[0069] The first configuration information includes a first reference signal resource set, the first reference signal resource set includes at least one reference signal resource, and the first configuration information is used to indicate the first reference signal resource set associated with the channel state information report.

[0070] The second configuration information is used to indicate the channel state information that needs to be included in the channel state information report. Exemplarily, the channel state information that needs to be included may include at least one of the following: a precoding matrix or a precoding matrix indicator for an antenna, channel quality or a channel quality indicator, reference signal received power, signal-to-interference-plus-noise ratio, channel coefficient, rank of the precoding matrix, etc. "Need to include" may also be referred to by other names, such as "need to include," "need to be configured," "should include," "should be configured," etc.

[0071] The third configuration information is used to indicate that a channel state information report is determined based on the first reference signal resource set. The third configuration information can also be understood as indicating a matching relationship between the channel state information report and the first reference signal resource set. It should be understood that there may be multiple channel state information reports and multiple reference signal resource sets within the communication system. The third configuration information indicates the matching relationship between the channel state information report and the reference signal resource set, so that the second communication node can determine, based on the third configuration information, which reference signal resource set to use to determine the channel state information report. For example, the communication system is configured with reference signal resource set 1, reference signal resource set 2, and reference signal resource set 3; and channel state information report A, channel state information report B, and channel state information report C; the third configuration information is used to indicate that channel state information report A is determined based on the reference signal resources within reference signal resource set 1, or indicates that channel state information report A is determined based on the reference signal resources within reference signal resource set 2. The second communication node can then determine, based on the third configuration information, whether channel state information report A is determined based on the reference signal resources within reference signal resource set 1, or whether channel state information report A is determined based on the reference signal resources within reference signal resource set 2.

[0072] In some embodiments, the first reference signal resource set includes a first group of reference signal resources and a second group of reference signal resources, and the grouping manner of the reference signal resources included in the first reference signal resource set is related to the transmission time of the reference signal resources included in the first reference signal resource set.

[0073] In some embodiments, the first set of reference signal resources precedes the second set of reference signal resources in the time domain.

[0074] For example, the reference signal resources included in the first reference signal resource set can be sorted according to the order of transmission time, and then based on the arrangement order, half of the reference signal resources located before the arrangement order in the time domain can be used as the first group of reference signal resources, and the other half can be used as the second group of reference signal resources.

[0075] For another example, the first communication node indicates the target reference signal resource in the first reference signal resource set, and can use the reference signal resources located before the target reference signal resource as the first group of reference signal resources, and use the reference signal resources located after the target reference signal resource as the second group of reference signal resources.

[0076] In some embodiments, the first information is further used to indicate that a channel state information report is determined based on the first set of reference signal resources, or that the channel state information report is determined based on the first set of reference signal resources and the second set of reference signal resources. In other words, the first information is further used to indicate that a channel state information report is determined based on some reference signal resources in the first reference signal resource set, or that the channel state information report is determined based on all reference signal resources in the first reference signal resource set.

[0077] It should be understood that when the first indication information is also used to indicate the determination of a channel state information report based on the first group of reference signal resources, on the one hand, the reference signal resources occupied by the reference signal can be saved, and computing power overhead can be saved; on the other hand, the second group of reference signal resources may be used to monitor channel state information, so that the reference signal resources on which the channel state information included in the monitoring channel state information report is based are different from the reference signal resources on which the channel state information included in the determination channel state information report is based, thereby adding additional reference signal resources for monitoring the channel state information, or avoiding the additional reference signal resource overhead occupied by the reference signal for monitoring the channel state information.

[0078] In some embodiments, the first information indicates that the channel state information report is determined based on the first set of reference signal resources, or that the channel state information report is determined based on the first set of reference signal resources and the second set of reference signal resources and is related to the value of the first information.

[0079] Combined with the above-mentioned first information, it is used to instruct the second communication node to feed back a channel state information report, and the first information is also used to instruct the second communication node whether to monitor the channel state information included in the channel state information report.

[0080] For example, when the first information takes the first value, the first information is used to instruct the second communication node to feed back a channel state information report, the first information is further used to instruct the second communication node not to monitor the channel state information included in the channel state information report, and the first information is further used to instruct the channel state information report to be determined based on the first set of reference signal resources. In this way, the second set of reference signal resources occupied by the reference signal for determining the channel state information report can be saved.

[0081] For another example, when the first information takes the second value, the first information is used to instruct the feedback of a channel state information report, the first information is further used to instruct the second communication node to monitor the channel state information included in the channel state information report, and the first information is further used to instruct the channel state information report to be determined based on the first set of reference signal resources. In this way, the channel state information report can be determined based on the first set of reference signal resources, and the channel state information can be monitored based on the second set of reference signal resources, thereby saving reference signal resources outside the first set of reference signal resources that would otherwise be occupied by the reference signal due to detecting the channel state information.

[0082] For another example, when the first information takes the third value, the first information is used to indicate the feedback channel state information report, the first information is also used to indicate that the second communication node does not monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the channel state information report is determined based on the first group of reference signal resources and the second group of reference signal resources.

[0083] For another example, when the first information takes the fourth value, the first information is used to indicate the feedback channel state information report, the first information is also used to indicate the second communication node to monitor the channel state information included in the channel state information report, and the first information is also used to indicate the determination of the channel state information report based on the first group of reference signal resources and the second group of reference signal resources.

[0084] It should be understood that instructing the second communication node to feed back a channel state information report and indicating whether to determine the channel state information report based on the first group of reference signal resources or based on the first group of reference signal resources and the second group of reference signal resources, using the same field on the first signaling, or using the same value on the same field on the first signaling, can reduce signaling overhead and reduce signaling complexity.

[0085] In some embodiments, the first information is further used to indicate whether the reference signal is transmitted on the second set of reference signal resources. It should be understood that the first information is further used to indicate whether the reference signal is transmitted on the second set of reference signal resources, so that the second communication node determines whether to receive the reference signal on the second set of reference signal resources based on the first information.

[0086] It should be noted that reference signals are currently transmitted on the first set of reference signal resources. Depending on the channel's stationarity in the time domain, reference signals may or may not be transmitted on the second set of reference signal resources. For example, when the channel is not stationary in the time domain, reference signals may need to be transmitted on the second set of reference signal resources to determine channel state information. However, when the channel is stationary in the time domain, channel state information can be determined without transmitting the reference signal on the second set of reference signal resources.

[0087] Depending on whether channel state information is monitored, reference signals may or may not be required to be transmitted on the second set of reference signal resources. For example, when channel state information needs to be monitored, the channel state information can be monitored based on the reference signals transmitted on the second set of reference signal resources. When channel state information monitoring is not required, it is not necessary to require the reference signals to be transmitted on the second set of reference signal resources. By indicating whether the reference signals are to be transmitted on the second set of reference signal resources by the first information, the overhead of the reference signals occupying the second set of reference signal resources can be reduced while meeting the requirements.

[0088] Based on the above description, as an example, the first information is also used to indicate whether the second communication node monitors the channel state information included in the channel state information report, and can be based on whether the indication reference signal is transmitted on the second group of reference signal resources to indicate whether the second communication node monitors the channel state information included in the channel state information report.

[0089] For example, when the first information indicates that a reference signal is transmitted on the second set of reference signal resources, it is determined that the second communication node monitors the channel state information included in the channel state information report. For another example, when the first information indicates that a reference signal is not transmitted on the second set of reference signal resources, it is determined that the second communication node does not monitor the channel state information included in the channel state information report.

[0090] As another example, the first information is also used to indicate whether the reference signal is transmitted on the second group of reference signal resources, and can be based on the channel state information included in the channel state information report indicating whether the second communication node monitors the channel state information to indicate whether the reference signal is transmitted on the second group of reference signal resources.

[0091] For example, when the first information is used to instruct the second communication node to monitor the channel state information included in the channel state information report, it is determined that the reference signal is transmitted on the second set of reference signal resources. For another example, when the first indication information is used to instruct the second communication node not to monitor the channel state information included in the channel state information report, it is determined that the reference signal is not transmitted on the second set of reference signal resources.

[0092] In some embodiments, the first information is further used to indicate whether the reference signal is transmitted on the second group of reference signal resources, which is related to the value of the first information.

[0093] In combination with the above-mentioned first information, it is used to indicate the feedback channel state information report, and the first information is also used to indicate whether the second communication node monitors the channel state information included in the channel state information report. For example, when the first information takes the first value, the first information is used to indicate the feedback channel state information report, and the first information is also used to indicate that the second communication node does not monitor the channel state information included in the channel state information report. The first information is also used to indicate that the reference signal is transmitted on the second group of reference signal resources.

[0094] For another example, when the first information takes the second value, the first information is used to indicate the feedback channel state information report, the first information is also used to indicate the second communication node to monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the reference signal is transmitted on the second group of reference signal resources.

[0095] For another example, when the first information takes the third value, the first information is used to indicate a feedback channel state information report, the first information is also used to indicate that the second communication node does not monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the reference signal is not transmitted on the second group of reference signal resources.

[0096] For another example, when the first information takes the fourth value, the first information is used to indicate the feedback channel state information report, the first information is also used to indicate the second communication node to monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the reference signal is not transmitted on the second group of reference signal resources.

[0097] In some embodiments, the first information is further used to indicate a transmission time of the channel state information report.

[0098] It should be understood that the first information is also used to indicate the transmission time included in the channel state information, so that the second communication node can determine the time to feed back the channel state information based on the first information.

[0099] In some embodiments, the transmission time of the channel state information report is related to the manner in which the channel state information report is determined.

[0100] As an example, when a channel state information report is determined based on a first group of reference signal resources, the transmission time of the channel state information report is determined based on the time at which the last reference signal resource of the first group of reference signal resources in the time domain is located. For example, the transmission time of the channel state information report may be after the time at which the last reference signal resource of the first group of reference signal resources in the time domain is located. This creates conditions for advancing the transmission time of the channel state information report to the time at which the second group of reference signal resources is located, thereby potentially enabling the transmission time of the channel state information report to be before the time at which the second group of reference signal resources is located, that is, the channel state information report is transmitted before the time at which the second group of reference signal resources is located.

[0101] As another example, when a channel state information report is determined based on the first group of reference signal resources and the second group of reference signal resources, the transmission time of the channel state information report is determined based on the time at which the last reference signal resource in the first group of reference signal resources and the second group of reference signal resources occurs in the time domain. For example, the transmission time of the channel state information report is after the time at which the last reference signal resource in the first group of reference signal resources and the second group of reference signal resources occurs in the time domain.

[0102] It should be understood that the first information is also used to indicate the transmission time of the channel state information report, that is, the transmission time of the channel state information report is determined based on the first information, so that the transmission time of the channel state information report is before the time when the last reference signal resource of the first reference signal resource set in the time domain is located.

[0103] The above embodiment is described using the example of the first configuration information including a first reference signal resource set. In some embodiments, the first configuration information also includes a second reference signal resource set. Reference signal antenna ports with the same index number in the second reference signal resource set and the first reference signal resource set can be understood as the same port.

[0104] It should be understood that reference signals are transmitted by reference signal antenna ports and carried by reference signal resources. Reference signals carried on different reference signal resources and transmitted by reference signal antenna ports with the same index number can be understood as reference signals transmitted by the same reference signal antenna port.

[0105] In some embodiments, the second reference signal resource set is used by the second communication node to monitor channel state information included in the channel state information report based on the second reference signal resource set.

[0106] In some embodiments, the first information is further used to indicate whether the reference signal is transmitted on the second reference signal resource set.

[0107] It should be understood that the first information is also used to indicate whether a reference signal is transmitted on the second reference signal resource set, so that the second communication node can determine whether to receive the reference signal on the second reference signal resource set based on the first information. For example, if the first information indicates that the reference signal is transmitted on the second reference signal resource set, the second communication node can determine to receive the reference signal on the second reference signal resource set based on the first information. If the first information indicates that the reference signal is not transmitted on the second reference signal resource set, the second communication node can determine not to receive the reference signal on the second reference signal resource set based on the first information, thereby reducing the overhead of the second communication node.

[0108] In some embodiments, the first information indicating whether the reference signal is transmitted on the second reference signal resource set is related to the value of the first information. For example, when the first information takes the first value, the first information is further used to indicate that the reference signal is transmitted on the second reference signal resource set. For another example, when the first information takes the second value, the first information is further used to indicate that the reference signal is not transmitted on the second reference signal resource set.

[0109] In some embodiments, the first information indicating whether the reference signal is transmitted on the second reference signal resource may be based on instructing the second communication node to feedback a channel state information report. For example, when the first information is used to instruct the second communication node to feedback a channel state information report, it is determined that the reference signal is transmitted on the second reference signal resource.

[0110] Exemplarily, in combination with the above-mentioned indication of whether the reference signal is transmitted on the second reference signal resource set based on instructing the second communication node to feed back the channel state information report, and the first information indicating whether the reference signal is transmitted on the second reference signal resource set, it is related to the value of the first information. For example, when the first information takes the first value, the first information is used to instruct the second communication node to feed back the channel state information report, and the first information is also used to indicate that the reference signal is transmitted on the second reference signal resource set. For another example, when the first information takes the second value, the first information is used to instruct the second communication node to feed back the channel state information report, and the first information is also used to indicate that the reference signal is not transmitted on the second reference signal resource set.

[0111] In some embodiments, the first information indicating whether the reference signal is transmitted on the second reference signal resource set may be based on whether the second communication node is monitoring the channel state information included in the channel state information report to indicate whether the reference signal is transmitted on the second reference signal resource set. For example, when the first information is also used to instruct the second communication node to monitor the channel state information included in the channel state information report, the reference signal is determined to be transmitted on the second reference signal resource set. For another example, when the first information is also used to instruct the second communication node not to monitor the channel state information included in the channel state information report, the reference signal is determined not to be transmitted on the second reference signal resource set, thereby saving signaling overhead.

[0112] Exemplarily, in combination with the above-mentioned indication of whether the second communication node monitors the channel state information included in the channel state information report to indicate whether the reference signal is transmitted on the second reference signal resource set, and the first information indicating whether the reference signal is transmitted on the second reference signal resource set, it is related to the value of the first information. For example, when the first information takes the first value, the first information is also used to instruct the second communication node to monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the reference signal is transmitted on the second reference signal resource set. For another example, when the first information takes the second value, the first information is also used to instruct the second communication node not to monitor the channel state information included in the channel state information report, and the first information is also used to indicate that the reference signal is not transmitted on the second reference signal resource set.

[0113] In some embodiments, the first information indicating whether the second communication node monitors the channel state information included in the channel state information report may be based on whether the reference signal is transmitted on the second reference signal resource set to indicate whether the second communication node monitors the channel state information included in the channel state information report. For example, when the first information is also used to indicate that the reference signal is transmitted on the second reference signal resource set, it is determined that the second communication node monitors the channel state information included in the channel state information report. For another example, when the first information is also used to indicate that the reference signal is not transmitted on the second reference signal resource, it is determined that the second communication node does not monitor the channel state information included in the channel state information report, thereby saving signaling overhead.

[0114] Exemplarily, in combination with the above-mentioned indication of whether the reference signal is transmitted on the second reference signal resource set to indicate whether the second communication node monitors the channel state information included in the channel state information report, and the first information indicating whether the reference signal is transmitted on the second reference signal resource set is related to the value of the first information. For example, when the first information takes the first value, the first information is also used to indicate that the reference signal is transmitted on the second reference signal resource set, and the first information is also used to instruct the second communication node to monitor the channel state information included in the channel state information report. For another example, when the first information takes the second value, the first information is also used to indicate that the reference signal is not transmitted on the second reference signal resource set, and the first information is also used to instruct the second communication node not to monitor the channel state information included in the channel state information report.

[0115] It should be noted that the above examples are only illustrative of the role of the first information and do not constitute a limitation on the scheme of the present disclosure. The scheme obtained by rearranging and combining the role of the above-mentioned first information should also fall within the scope of protection of the scheme of the present disclosure.

[0116] The above embodiment is explained by taking the example that the first information has the function of instructing the second communication node to feed back the channel state information report, and the first information also has the function of instructing the second communication node whether to monitor the channel state information included in the channel state information report. In some embodiments, the first information may also only have the function of instructing the second communication node to feed back the channel state information report. When the first communication node sends the first information to the second communication node, the first communication node may also send the second information to the second communication node. The second information is used to indicate whether the second communication node monitors the channel state information included in the channel state information report. The second information may be carried in the first signaling or in the second signaling. The second signaling is different from the first signaling. That is to say, the first communication node may also use two different pieces of information or two different signaling to respectively instruct the second communication node to feed back the channel state information report and to instruct the second communication node whether to monitor the channel state information included in the channel state information report.

[0117] It should be understood that when the second information is also carried in the first signaling, the second information can be understood as another field (domain) in the first signaling that is different from the field (domain) where the first information is located.

[0118] In some embodiments, the second signaling is DCI signaling.

[0119] In some embodiments, after the first communication node sends the first information to the second communication node, that is, after S201, the first communication node can receive a channel state information report sent by the second communication node, and the channel state information report includes the channel state information that the channel state information report indicated by the above-mentioned second configuration information must include. The first communication node can determine a data transmission strategy with appropriate transmission effect between it and the second communication node based on the channel state information report.

[0120] In some embodiments, as shown in FIG5 , an embodiment of the present disclosure 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 . The method includes the following S401 .

[0121] S401. Receive first information sent by a first communication node.

[0122] In some embodiments, when a first communication node requires a second communication node to monitor channel state information included in a channel state information report, or requires the second communication node to not monitor or stop monitoring the channel state information included in the channel state information report, the first communication node sends first information to the second communication node. Accordingly, the second communication node receives the first information sent by the first communication node. The first information is used to instruct the second communication node to feedback the channel state information report, and the first information is also used to instruct the second communication node whether to monitor the channel state information included in the channel state information report.

[0123] For the description of the first information, reference may be made to the corresponding description of the first information in S201 above, which will not be repeated here.

[0124] In some embodiments, before the second communication node receives the first information sent by the first communication node, that is, before the above-mentioned S401, as shown in FIG6, the method further includes the following S501.

[0125] S501. Receive at least one item of first configuration information, second configuration information, and third configuration information sent by a first communication node.

[0126] For descriptions of the first configuration information, the second configuration information, and the third configuration information, reference may be made to the corresponding descriptions in S301 above, which will not be repeated here.

[0127] In some embodiments, after the second communication node receives the first information, that is, after S401, the second communication node may obtain a channel state information report based on at least one of the first configuration information, the second configuration information, and the third configuration information, as well as the first information. After obtaining the channel state information report, the second communication node may send the channel information report to the first communication node, so that the first communication node can determine a data transmission strategy that has an appropriate transmission effect with the second communication node based on the channel state information report.

[0128] The above mainly introduces the solution provided by the present disclosure from the perspective of the 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 realize the above functions.
