[0001] The present application relates to the field of wireless communication technology, for example, to a reference signal transmission and reception method, a communication node and a storage medium. Background Art

[0002] The process of acquiring and utilizing channel state information in wireless communication systems primarily involves: a base station transmits a reference signal; a terminal receives and measures the reference signal, determines the channel state information from the base station to the terminal, and reports the channel state information to the base station; the base station receives the channel state information reported by the terminal, determines a data transmission strategy based on the channel state represented by the received channel state information, and transmits data, thereby improving data transmission efficiency and communication quality. However, wireless channels are time-varying. Each time the base station transmits a reference signal, the terminal receives and measures the reference signal, and provides feedback on the channel state based on the measurement. The base station uses the feedback from the terminal until the next reference signal transmission results in an updated channel state. If the base station and terminal are to transmit based on real-time channel state information, this process must be repeated multiple times, resulting in high signaling overhead and resource consumption. The flexibility and complexity of reference signal transmission need to be improved and reduced.

[0018] An embodiment of the present application can implement a method for acquiring channel status: the terminal receives and measures a limited number of reference signals, extracts parameters that can derive the time-varying channel status based on the measurement of the limited number of reference signals, and feeds back the extracted parameters that can derive the time-varying channel status to the base station; the base station derives the time-varying channel status based on the obtained parameters that can derive the time-varying channel status; the base station uses the parameters that can derive the time-varying channel status obtained once to derive the channel status at different times in the future until the parameters that can derive the time-varying channel status change.

[0019] This embodiment extracts a parameter capable of inferring the time-varying channel state and uses it to infer the time-varying channel state for use in multiple future reference signal transmissions. This means that this embodiment can indicate multiple reference signal transmissions in a single channel state indication. This method reduces the terminal's channel state information reporting overhead, reduces the delay associated with reporting channel state information, and minimizes the mismatch between channel state information and the current channel state caused by the time interval between channel state information reports.

[0020] Based on the transmission method of the Reference Signal (RS), the Reference Signal can be divided into periodic Reference Signal, semi-persistent Reference Signal, and aperiodic Reference Signal. The base station configures the Reference Signal Resource (RS resource) and transmits the Reference Signal on the RS resource. The base station can configure the Reference Signal Resource at multiple levels. The first level is the Reference Signal Scenario (RS setting), which can include at least one Reference Signal Resource Set (RS resource set); the second level is the Reference Signal Resource Set, which can include at least one Reference Signal Resource; and the third level is the Reference Signal Resource, which can specify the Orthogonal Frequency Division Multiplexing (OFDM) symbol and frequency domain location used for Reference Signal transmission.

[0021] For periodic reference signals, the base station configures the period and time slot offset of the reference signal resources, and then transmits the reference signal on the reference signal resources 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 it is necessary to transmit a reference signal, the base station can first activate the reference signal resource set using medium access control (MAC) signaling, and then transmit the reference signal resources on the reference signal resource set at the configured time; when it is necessary to stop the reference signal resources, the base station can deactivate the reference signal resource set using MAC signaling. For aperiodic reference signals, when it is necessary to transmit a reference signal, the base station can use downlink control information format (DCI format) signaling to trigger the reference signal resource set, and then transmit the reference signal once on the reference signal resource corresponding to the reference signal resource set within a time slot. Based on the above embodiment, the terminal receives the base station's configuration of the reference signal (the configuration of the reference signal can be understood as the configured reference signal resource) and receives the reference signal according to the configuration of the reference signal.

[0022] However, the reference signal transmission methods in related technologies have certain shortcomings. For example, because periodic reference signals are transmitted over and over again on reference signal resources, they occupy a large amount of wireless resource overhead, reducing the efficiency of wireless resource utilization, such as reducing throughput and spectrum efficiency. Semi-persistent reference signals use MAC signaling to activate and deactivate reference signal resources, resulting in a long time span from the start signaling to the final execution, which is not flexible enough. If the time for transmitting the reference signal using the semi-persistent reference signal method is short, it is easy to lose the opportunity to capture the channel state. If the time for transmitting the reference signal using the semi-persistent reference signal method is longer, the reference signal occupies too much wireless resource overhead. In addition, the reference signal transmission process requires two MAC signalings, which increases the MAC signaling overhead. For non-periodic reference signals, the downlink control information format signaling is triggered once before the reference signal is transmitted once. If the reference signal needs to be transmitted multiple times, a signaling storm may occur.

[0023] In an embodiment of the present application, a reference signal transmission method is proposed, in which a first communication node configures configuration information of a reference signal resource, and transmits a reference signal to a second communication node on the reference signal resource according to the configuration information of the reference signal resource. This can save unnecessary reference signal transmission overhead, effectively transmit the reference signal, and improve the flexibility of reference signal transmission.

[0024] FIG1 is a flowchart of a reference signal transmission method provided by an embodiment. The method can be applied to a first communication node (such as a base station). As shown in FIG1 , the method provided by this embodiment includes step 110 and step 120 .

[0025] In step 110, configuration information of a reference signal resource is configured, where the configuration information includes a time domain symbol and a frequency domain position of the reference signal.

[0026] In step 120, the reference signal is transmitted on the reference signal resource according to the configuration information.

[0027] In this embodiment, the time domain symbol may refer to an OFDM symbol. Wireless communication has developed to the fifth generation of communication technology, among which the Long Term Evolution (LTE) technology in the fourth generation of wireless communication technology and the New Radio (NR) technology in the fifth generation of wireless communication technology are technologies based on OFDM. In OFDM technology, the smallest frequency domain unit is a subcarrier, and the smallest time domain unit is an OFDM symbol. To facilitate the use of frequency domain resources, a resource block (Resource Block) can be defined, and a resource block can be defined as a specific number of consecutive subcarriers; a bandwidth part (BWP) is also defined, and a bandwidth block can be defined as another specific number of consecutive resource blocks on a carrier; to facilitate the use of time domain resources, a time slot is defined, and a time slot can be defined as another specific number of consecutive OFDM symbols.

[0028] In this embodiment, the first communication node configures the configuration information of the reference signal resource. There are two ways to configure the configuration information of the reference signal resource: one scenario is that the first communication node configures the configuration information of the reference signal resource by broadcasting, that is, determines the configuration information of the reference signal resource and notifies it by broadcasting. Another scenario is that the first communication node configures the configuration information of the reference signal resource for the second communication node, that is, the first communication node configures the configuration information of the reference signal resource and transmits the reference signal on the reference signal resource according to the configuration information, and the second communication node receives the configuration information of the reference signal resource and receives the reference signal on the reference signal resource according to the configuration information. The first communication node can be a base station and the second communication node can be a terminal; or the first communication node can be a first terminal and the second communication node can be a second terminal; or the first communication node can be a node in wireless communication and the second communication node can be another node in wireless communication; this is not limited here.

[0029] The configuration information of the reference signal resource may be used to indicate the reference signal resource, and may, for example, indicate one of the following: the OFDM symbol of the reference signal, the frequency domain position of the reference signal, the number of reference signal ports, the code division multiplexing scheme of the reference signal ports, and the period and offset of the reference signal. The OFDM symbol of the reference signal is also the OFDM symbol of the reference signal resource, the frequency domain position of the reference signal is also the frequency domain position of the reference signal resource, the number of reference signal ports is also the number of ports of the reference signal resource, the code division multiplexing scheme of the reference signal ports is also the code division multiplexing scheme of the ports of the reference signal resource, and the period and offset of the reference signal are also the period and offset of the reference signal resource.

[0030] The first communication node transmits a corresponding reference signal on the reference signal resource according to the configuration information of the reference signal resource. In this case, the node that needs to receive the reference signal (i.e., the second communication node) can receive the configuration information of the reference signal resource and receive the reference signal on the reference signal resource according to the configuration information of the reference signal resource.

[0031] In this embodiment, the configuration information of the reference signal resource can be flexibly configured by the first communication node. On this basis, the reference signal is transmitted on the reference signal resource according to the configuration information, which can effectively improve the flexibility of the reference signal transmission, thereby conveniently completing the transmission of the reference signal, reducing the complexity of the system, saving unnecessary reference signal transmission overhead, and reducing resource occupancy. For example, it can avoid blindly using more wireless resources to transmit reference signals, avoid blindly and invalidly transmitting reference signals, avoid invalid blind detection of reference signals, etc.

[0032] In one embodiment, before step 110, the method further includes: triggering transmission of a reference signal through signaling in a downlink control information (DCI) format; wherein, signaling in a DCI format triggers transmission of the reference signal on the reference signal resource D times, where D is a positive integer.

[0033] In 4G or 5G wireless communications, the first communication node can carry the DCI format on the Physical Downlink Control Channel (PDCCH) and transmit the DCI in the DCI format; uplink data transmission, downlink data transmission and time slot format can be scheduled through DCI signaling or signaling in the DCI format. A reference signal, a reference signal resource, or a reference signal resource set can also be triggered through DCI signaling or signaling in the DCI format. By triggering a reference signal once through DCI signaling or signaling in the DCI format, the first communication node can transmit a reference signal once on the corresponding reference signal resource. When the reference signal needs to be transmitted multiple times, or the terminal (i.e., the second communication node) needs to measure the reference signal multiple times, the DCI signaling or signaling in the DCI format must be used multiple times to trigger the reference signal; for example, if the reference signal needs to be transmitted multiple times continuously, or the terminal needs to measure the reference signal multiple times continuously, the DCI signaling or signaling in the DCI format must be used multiple times to trigger the reference signal. However, repeated use of DCI signaling or DCI-formatted signaling to trigger reference signals can easily lead to signaling storms, increasing signaling interference within the communication system and the pressure on the communication system to process signaling, thereby degrading system performance and even causing system crashes. Similarly, triggering reference signal resources or reference signal resource sets using DCI signaling or DCI-formatted signaling carries similar risks.

[0034] In this embodiment, in order to avoid the occurrence of problems such as signaling storms, the first communication node can trigger the transmission of a reference signal through DCI signaling or DCI format signaling, wherein one DCI signaling or DCI format signaling triggers the reference signal to be transmitted D times on the corresponding reference signal resource, that is, D can be the number of times the reference signal is transmitted on the corresponding reference signal resource, and D can be a positive integer. By triggering the reference signal to be transmitted multiple times on the reference signal resource through one DCI signaling or DCI format signaling, it is possible to avoid the situation where the DCI format signaling is used multiple times to trigger the reference signal, thereby reducing the number of times the DCI format signaling is used, thereby effectively avoiding the control signaling storm. The parameter D can be set to an integer of 1 or greater than 1 according to actual needs; for example, the value of the parameter D can be set according to the number of reference signals that the communication system needs to transmit, the transmission frequency, the frequency of use of the DCI format signaling in the system, etc.

[0035] In one embodiment, the configuration information includes information on the number of times D the reference signal is transmitted on the reference signal resource.

[0036] In this embodiment, D is the number of times a reference signal is transmitted on a reference signal resource. Information about D may include: a field of a DCI format signaling that triggers a reference signal is mapped to a value of D, a field of a DCI format signaling that triggers a reference signal is mapped to selection information for a candidate value of D, a reference value of D, offset information relative to the reference value of D, and a value of D. On this basis, the configuration information for configuring the reference signal resource may include information about the number of times D a reference signal is transmitted on the reference signal resource, to indicate D. The configuration information may include any one of the information about D, to indicate D. For example, the configuration information may include a field of a DCI format signaling that triggers a reference signal mapped to selection information for a candidate value of D, to indicate D; or the configuration information may include a value of D, to indicate D, etc.

[0037] In one embodiment, the signaling in the DCI format carries information on the number of times D the reference signal is transmitted on the reference signal resource.

[0038] In this embodiment, the signaling in the DCI format for triggering the reference signal may carry information about the number of times D the reference signal is transmitted on the corresponding reference signal resource, so as to indicate D. For example, the signaling in the DCI format for triggering the reference signal may carry the value of D, so as to indicate D; or a field in the signaling in the DCI format for triggering the reference signal may be mapped to the value of D, so as to indicate D; or a field in the signaling in the DCI format for triggering the reference signal may be mapped to information for selecting candidate values ​​of D, so as to indicate D.

[0039] In one embodiment, a portion of information about D carried by signaling in the DCI format and another portion of information about D included in the configuration information jointly indicate the number of times D that the reference signal is transmitted on the reference signal resource.

[0040] In this embodiment, the number of times D that a reference signal is transmitted on a reference signal resource may be jointly indicated by signaling in a DCI format and configuration information. Exemplarily, the number of times D that a reference signal is transmitted on a reference signal resource may be jointly indicated by a portion of information about D carried in the DCI format signaling and another portion of information about D included in the configuration information. Specifically, for example, the portion of information about D carried in the DCI format signaling may be information for selecting candidate values ​​for D, and the other portion of information about D included in the configuration information may be a value mapped from a field in the DCI format signaling to D, and D may be jointly indicated based on these two portions of information. For another example, the portion of information about D carried in the DCI format signaling may be offset information relative to a reference value for D, and the other portion of information included in the configuration information may be a reference value for D, and D may be jointly indicated based on these two portions of information.

[0041] In one embodiment, the configuration information includes a time offset between two adjacent reference signal transmissions.

[0042] In this embodiment, the time offset between two adjacent reference signal transmissions can be understood as follows: the time of the previous reference signal transmission is used as the reference time, and the time offset between the time of the next reference signal transmission and the reference time is the time offset between the two adjacent reference signal transmissions. For example, assuming the time of the d-th reference signal transmission is used as the reference time, the time offset between the time of the d+1-th reference signal transmission and the reference time can be used as the time offset between the d-th and d+1-th reference signal transmissions.

[0043] The configuration information for the reference signal resource may include the time offset between two adjacent reference signal transmissions. For example, one embodiment of the configuration information for the reference signal resource including the time offset between two adjacent reference signal transmissions may be that the configuration information may include the numerical value of the time offset between the two adjacent reference signal transmissions. Another embodiment may be that the configuration information may include information for selecting candidate values ​​for the time offset between two adjacent reference signal transmissions. Still another embodiment may be that the configuration information may include an offset value relative to a reference value for the time offset between two adjacent reference signal transmissions.

[0044] The candidate time offset value between two adjacent reference signal transmissions may be predetermined, for example, in one manner, it may be predefined by a protocol, or in another manner, it may be negotiated and predetermined by both communicating parties. The reference time offset value between two adjacent reference signal transmissions may also be predetermined, for example, in one manner, it may be predefined by a protocol, or in another manner, it may be negotiated and predetermined by both communicating parties.

[0045] In one embodiment, the signaling in the DCI format carries the time offset between two adjacent reference signal transmissions.

[0046] In this embodiment, the signaling in the DCI format for triggering the reference signal may carry the time offset between two adjacent reference signal transmissions. Exemplarily, one way for the signaling in the DCI format for triggering the reference signal to carry the time offset between two adjacent reference signal transmissions may be that the signaling in the DCI format may carry the numerical value of the time offset between two adjacent reference signal transmissions. Another way may be that a field of the signaling in the DCI format is mapped to selection information for candidate values ​​of the time offset between two adjacent reference signal transmissions. Yet another way may be that a field of the signaling in the DCI format is mapped to an offset value relative to a time offset reference value of two adjacent reference signal transmissions.

[0047] In one embodiment, a portion of the time offset information of two adjacent reference signal transmissions carried by DCI format signaling and another portion of the time offset information of two adjacent reference signal transmissions included in the configuration information jointly indicate the time offset of two adjacent reference signal transmissions.

[0048] In this embodiment, the time offset of two adjacent reference signal transmissions can be jointly indicated by signaling in a DCI format and configuration information. Exemplarily, the time offset of two adjacent reference signal transmissions can be jointly indicated by a portion of the time offset information of two adjacent reference signal transmissions carried in the DCI format signaling and another portion of the time offset information of two adjacent reference signal transmissions included in the configuration information. Specifically, for example, the portion of the time offset information of two adjacent reference signal transmissions carried in the DCI format signaling can be information for selecting candidate time offset values ​​for two adjacent reference signal transmissions, and the other portion of the time offset information of two adjacent reference signal transmissions included in the configuration information can be candidate values ​​for the time offset of two adjacent reference signal transmissions. Based on these two portions of information, the time offset of two adjacent reference signal transmissions can be jointly indicated. For another example, the portion of the time offset information of two adjacent reference signal transmissions carried in the DCI format signaling can be an offset value relative to a reference value for the time offset of two adjacent reference signal transmissions, and the other portion of the time offset information of two adjacent reference signal transmissions included in the configuration information can be a reference value for the time offset of two adjacent reference signal transmissions. Based on these two portions of information, the time offset of two adjacent reference signal transmissions can be jointly indicated.

[0049] In one embodiment, the number of times the reference signal is transmitted on the reference signal resource is determined according to the time offset between two adjacent reference signal transmissions.

[0050] In this embodiment, the first communication node may indicate a time offset between two adjacent reference signal transmissions. For example, one manner in which the first communication node indicates the time offset between two adjacent reference signal transmissions may be that the configuration information of the reference signal resource includes the time offset between the two adjacent reference signal transmissions. Another manner may be that signaling in a DCI format may carry the time offset between the two adjacent reference signal transmissions.

[0051] In this embodiment, when the first communication node indicates the time offset between two adjacent reference signal transmissions, the number of reference signal transmissions D on the reference signal resource can be determined based on the time offset between the two adjacent reference signal transmissions. Exemplarily, one method for determining the number of reference signal transmissions on the reference signal resource based on the time offset between the two adjacent reference signal transmissions may be that the protocol predetermines a mapping table from the time offset between two adjacent reference signal transmissions to the number of transmissions D, and D is determined based on the mapping table and the time offset between the two adjacent reference signal transmissions. Another method may be to set a monotonically increasing mapping relationship between the number of reference signal transmissions D on the reference signal resource and the time offset between two adjacent reference signal transmissions; the monotonically increasing mapping relationship may be a monotonically increasing proportional relationship, a monotonically increasing linear relationship, a monotonically increasing exponential relationship, a monotonically increasing logarithmic relationship, or the like. This embodiment adjusts the time accuracy of reference signal measurement by the terminal by setting a monotonically increasing mapping relationship, thereby increasing the stability of the measured channel state parameters.

[0052] Another method for determining the number D of reference signal transmissions on a reference signal resource based on the time offset between two adjacent reference signal transmissions may be to establish a monotonically decreasing mapping relationship between the number D of reference signal transmissions on the reference signal resource and the time offset between two adjacent reference signal transmissions; wherein the monotonically decreasing mapping relationship may be a monotonically decreasing proportional relationship, a monotonically decreasing linear relationship, a monotonically decreasing inverse proportional relationship, or a monotonically decreasing quadratic function relationship. This embodiment sets a monotonically decreasing mapping relationship to maintain the time interval of the terminal's reference signal measurement, thereby determining the proportion of measurement time overhead during the channel state information retention period, thereby preventing overhead fluctuations from affecting data transmission efficiency.

[0053] In one embodiment, the time offset between two adjacent reference signal transmissions is determined according to the number of times the reference signal is transmitted on the reference signal resource.

[0054] In this embodiment, the first communication node may indicate the number of times D that the reference signal is transmitted on the reference signal resource. For example, one manner for the first communication node to indicate the number of times D that the reference signal is transmitted on the reference signal resource may be that the configuration information of the reference signal resource may include the number of times D that the reference signal is transmitted on the reference signal resource. Another manner may be that signaling in a DCI format may carry the number of times D that the reference signal is transmitted on the reference signal resource.

[0055] In this embodiment, when the first communication node indicates the number of times D that a reference signal is transmitted on a reference signal resource, the time offset between two adjacent reference signal transmissions can be determined based on the number of times D that the reference signal is transmitted on the reference signal resource. Exemplarily, one approach to determining the time offset between two adjacent reference signal transmissions based on the number of times the reference signal is transmitted on the reference signal resource may be that a protocol predetermines a mapping table from the time offset between two adjacent reference signal transmissions to the number of times D that the reference signal is transmitted on the reference signal resource, and the time offset between two adjacent reference signal transmissions is determined based on the mapping table and the number of times D that the reference signal is transmitted. Another approach may be to set a monotonically increasing mapping relationship between the time offset between two adjacent reference signal transmissions and the number of times D that the reference signal is transmitted on the reference signal resource. The monotonically increasing mapping relationship may be a monotonically increasing proportional relationship, a monotonically increasing linear relationship, a monotonically increasing exponential relationship, or a monotonically increasing logarithmic relationship. In this embodiment, by setting this monotonically increasing mapping relationship, the time accuracy of the terminal's reference signal measurement is adjusted, thereby increasing the stability of the measured channel state parameters.

[0056] Another method for determining the time offset between two adjacent reference signal transmissions based on the number of times the reference signal is transmitted on the reference signal resource may be to set a monotonically decreasing mapping relationship between the time offset between two adjacent reference signal transmissions and the number of times the reference signal is transmitted on the reference signal resource, D. The monotonically decreasing mapping relationship may be a monotonically decreasing proportional relationship, a monotonically decreasing linear relationship, a monotonically decreasing inverse proportional relationship, or a monotonically decreasing quadratic function relationship. This embodiment sets the monotonically decreasing mapping relationship to maintain the time interval of the terminal's reference signal measurement, thereby determining the proportion of measurement time overhead during the channel state information retention period, thereby preventing overhead fluctuations from affecting data transmission efficiency.

[0057] In one embodiment, the configuration information includes K time offsets, where different time offsets correspond to different reference signal transmission rounds, and K is a positive integer.

[0058] In this embodiment, the configuration information of the reference signal resource may include K time offsets for reference signal transmission, where different time offsets correspond to different reference signal transmission rounds, such as one time offset may correspond to one or more reference signal transmission rounds; or one time offset may correspond to the index number of one or more reference signal transmissions; and K may be a positive integer.

[0059] For example, the configuration information of the reference signal resource may include K time offsets for reference signal transmission, where one time offset corresponds to one round of reference signal transmission, or one time offset corresponds to an index number of reference signal transmission. For another example, the configuration information of the reference signal resource may include K time offsets for reference signal transmission, where one time offset corresponds to two rounds of reference signal transmission, or one time offset corresponds to two index numbers of reference signal transmission. For another example, the configuration information of the reference signal resource may include K time offsets for reference signal transmission, where one time offset corresponds to X rounds of reference signal transmission, or one time offset corresponds to X index numbers of reference signal transmission, where X may be a positive integer.

[0060] In one embodiment, the configuration information includes K time offsets, where different time offsets correspond to different reference signal transmission rounds in sequence, and K is a positive integer.

[0061] In this embodiment, the configuration information of the reference signal resource may include K time offsets for the reference signal transmission, where different time offsets may correspond in sequence to different reference signal transmission rounds, such as one time offset may correspond in sequence to one or more reference signal transmission rounds; or one time offset may correspond in sequence to the index number of one or more reference signal transmissions; and K may be a positive integer.

[0062] For example, the configuration information of the reference signal resource may include K time offsets for sequential transmission of the reference signal, where one of the time offsets may correspond sequentially to a round of reference signal transmission, or one of the time offsets may correspond sequentially to an index number of reference signal transmission. For another example, the configuration information of the reference signal resource may include K time offsets for sequential transmission of the reference signal, where one of the time offsets may correspond sequentially to two rounds of reference signal transmission, or one of the time offsets may correspond sequentially to two index numbers of reference signal transmission. For another example, the configuration information of the reference signal resource may include K time offsets for sequential transmission of the reference signal, where one of the time offsets may correspond sequentially to X rounds of reference signal transmission, or one of the time offsets may correspond sequentially to X index numbers of reference signal transmission, where X is a positive integer.

[0064] In this embodiment, the configuration information of the reference signal resource may include: a period of the reference signal resource and a time slot offset of the reference signal resource.

[0065] The first communication node may indicate at least one of the number of consecutive transmissions (D') of the reference signal on the reference signal resource and the number of consecutive stops (N) of the reference signal on the reference signal resource. D' may be a positive integer, and N may be a non-negative integer. For example, in the first communication node, the indication may be through configuration information or signaling in a DCI format.

[0066] The time point at which the reference signal is transmitted on the reference signal resource can be determined according to the period of the reference signal resource and the time slot offset of the reference signal resource. At the corresponding time point, the reference signal is continuously transmitted D' times on the reference signal resource.

[0067] Then the reference signal stops transmitting N times continuously on the reference signal resource.

[0068] In one embodiment, at least one of D′ and N is indicated by signaling in a DCI format.

[0069] In this embodiment, the first communication node may indicate at least one of D' and N by using DCI format signaling, for example, the DCI format signaling may carry at least one of D' and N.
