[0038] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0039] The following explains the terms involved in the embodiments of the present application to facilitate the reader's understanding.

[0040] (1) Orthogonal frequency division multiplexing (OFDM)

[0041] 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 both based on orthogonal frequency division multiplexing technology. In orthogonal frequency division multiplexing technology, the smallest frequency domain unit is a subcarrier, and the smallest time domain unit is an orthogonal frequency division multiplexing symbol. An orthogonal frequency division multiplexing symbol is a frequency domain sequence. In order to facilitate the use of frequency domain resources, resource blocks (RBs) are defined, and a resource block is defined as a specific number of continuous subcarriers; bandwidth blocks (BWPs) are also defined, and a bandwidth block is defined as another specific number of continuous resource blocks on a carrier. In order to facilitate the use of time domain resources, time slots are defined, and a time slot is defined as a specific number of continuous orthogonal frequency division multiplexing symbols.

[0042] (2) Channel State Information

[0043] The channel state information includes at least one of a channel quality indicator (CQI) and a precoding matrix indicator, wherein the channel quality indicator is used to indicate the quality of the channel, and the precoding matrix indicator is used to indicate the precoding matrix on the antenna of the access network device.

[0044] With regard to the reporting method of the channel quality indicator, one reporting method of the channel quality indicator is wideband channel quality indicator reporting (wideband CQI reporting), that is, a channel state information reporting band (CSI reportingband) reports a channel quality indicator; another reporting method of the channel indicator is subband channel quality indicator reporting, that is, the channel state information reporting band is in units of subbands, and each subband reports a channel quality.

[0045] Wherein, subband is a frequency domain unit, and subband is defined as X consecutive resource blocks. In this application, it may be referred to as a channel quality indicator subband, or a channel quality indicator subband, or a subband. X is referred to as the size of the channel quality indicator subband, or the channel quality indicator subband size, or the subband size. The bandwidth block is divided into subbands, and the channel state information reporting band is defined by a subset of the subbands of the bandwidth block. The channel state information reporting band is the band where the channel state information needs to be reported.

[0046] As for the determination method of the channel quality indicator, the channel quality can be determined according to the strength of the reference signal received by the terminal device or the signal-to-noise ratio of the reference signal. In the channel state information reporting band, if the change of the channel quality is small, the channel quality indicator is reported by the wideband channel quality indicator report, which can effectively reduce the resource overhead; in the channel state information reporting band, if the change of the channel quality in the frequency domain is large, the channel quality indicator is reported by the subband channel quality indicator report, which can increase the accuracy of the channel quality report.

[0047] Regarding the reporting method of the precoding matrix symbol, one reporting method of the precoding matrix symbol is: reporting a precoding matrix symbol through the channel state information reporting band, that is, the precoding matrix symbol corresponds to the entire channel state information reporting band. Another reporting method of the precoding matrix symbol is: reporting through the subband channel quality indicator, that is, the channel state information reporting band is based on subbands, and each subband reports a precoding matrix symbol, or each subband reports a component of a precoding matrix symbol. Another reporting method of the precoding matrix symbol is: each subband indicates Y precoding matrices.

[0048] Wherein, Y is a positive integer. Y may represent the number of precoding matrices; in terms of the frequency domain granularity of the feedback precoding matrix, Y may also represent the number of precoding matrix subbands included in each subband, or the number of precoding matrix subbands included in each channel quality indicator subband.

[0049] For example, the components of a precoding matrix symbol reported for each subband may be: taking the precoding matrix symbol consisting of sub-precoding matrix symbol 1 and sub-precoding matrix symbol 2 as an example. Mode 1 is: the entire frequency band reports sub-precoding matrix symbol 1, and each subband reports a sub-precoding matrix symbol 2. Mode 2 is: each subband reports a sub-precoding matrix symbol 1 and a sub-precoding matrix symbol 2.

[0050] The terms involved in the embodiments of the present application are explained in detail above.

[0051] With the development of wireless communication technology, determining the communication data transmission strategy through channel state information has become an important way to improve the data transmission performance in the channel. For example, the access network device sends a reference signal, and the terminal device receives and measures the reference signal to predict the channel state information from the access network device to the terminal device, and reports the measured channel state information to the access network device. Furthermore, the access network device can determine the data transmission strategy through the channel state information to improve the efficiency of data transmission with the device and improve the performance of the communication system.

[0052] However, the communication channel between the access network device and the terminal device is a time-varying channel, which means that there is a time delay from the time when the reference signal is sent to the time when the channel state information is used. During the time delay, the state of the communication channel will change, and the state of the communication channel when the access network device sends the reference signal is different from the state of the communication channel when the access network device transmits data to the terminal. Therefore, the channel state information directly measured by the terminal device based on the reference signal has errors, which makes the performance of the access network device to determine the data transmission strategy through the channel state information relatively low.

[0053] At present, terminal equipment measures multiple reference signals to predict channel state information of a communication channel at a future time, and reports the channel state information at the future time to the access network equipment, so as to reduce the error of the channel state information caused by the data transmission delay between the sending of the reference signal and the transmission of data by the access network equipment to the terminal, thereby significantly improving the performance of the data transmission strategy determined by the access network equipment based on the channel state information at the future time.

[0054] However, the current mechanism for obtaining predicted channel state information has limitations, which often cause communication system crashes, resource waste, and reduced quality and quantity of channel state information. While ensuring the stability of terminal equipment, determining the channel state information of the wireless channel has become an urgent problem to be solved in the current and future 6G.

[0055] In the following, the problem of causing the collapse of the communication system is described in detail through the first aspect. The problem of resource waste is described in detail through the second aspect. The problem of the quality and quantity of the channel state information obtained is described in detail through the third aspect.

[0056] First, due to the limited capabilities of the terminal equipment itself, when the number of reference signals measured is too large, it will cause great data pressure on the terminal equipment side and even cause the communication system to collapse.

[0057] Furthermore, since the terminal device has limited capabilities, if the terminal device is instructed to determine the channel state information for too many time periods, it will also cause great data pressure on the terminal device and even cause the communication system to collapse.

[0058] Secondly, when the number of reference signals measured is too large, the terminal device cannot effectively use the reference signals beyond its own processing capabilities, which will cause resource waste. Therefore, while ensuring the stability of the terminal device, determining the channel state information of the wireless channel has become an urgent problem to be solved.

[0059] Furthermore, if the access network device prepares excessive wireless resources corresponding to the channel state information reported by the terminal for too many time periods, the terminal cannot determine the channel state information for so many time periods due to its own capabilities, that is, it cannot use so many wireless resources, resulting in a waste of wireless resources.

[0060] Thirdly, when the computing power of the terminal device is unknown, the access network device will instruct the terminal device to determine the channel status information for too few time periods in order to ensure the normal operation of the terminal device. Although this ensures the normal operation of the terminal device, it cannot meet the access network device's own requirements for channel quality or quantity.

[0061] Moreover, when the capability parameters of the terminal device are unknown, in order to ensure the normal operation of the terminal device, the access network device will configure a very small number of reference signal resources that deviates from its own needs, thereby losing the accuracy of the obtained channel state information, and also causing a decrease in the quality and quantity of the obtained channel state information.

[0062] In view of this, the present application provides a method for processing channel state information, in which the first node sends a capability parameter to the second node. By sending the capability parameter to the second node, the first node can enable the second node to configure the configuration information that matches the capability parameter for the first node. The first node receives the configuration information from the second node, and receives a reference signal that matches the capability of the first node based on the configuration information to avoid receiving too many or too few reference signals; thereby enabling the first node to receive and process reference signal resources that match its own capabilities. Furthermore, the first node reports the channel state information to the second node.

[0063] The above technical solution can solve the problem of resource waste currently caused in the process of acquiring channel state information, and can configure the first node with configuration information that matches its own capabilities, thereby improving resource utilization.

[0064] Furthermore, in the method for processing channel state information provided by the present application, the first node determines the channel state information of a time period that is compatible with the capabilities of the first node based on the configuration information, so as to avoid determining the channel state information of too many or too few time periods; thereby enabling the first node to process the channel state information of the time period that is compatible with its own capabilities.

[0065] It can be seen from this that the channel state information processing method provided in the present application can also solve the problems of communication system crash caused by the current process of obtaining channel state information and the decrease in the quality and quantity of the obtained channel state information, improve the quality and quantity of the obtained channel state information, and prevent the communication system crash caused by the process of obtaining channel state information.

[0102] It should be pointed out that the various embodiments of the present application can learn from or refer to each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can all refer to each other without limitation.

[0103] Figure 3 A flowchart of a method for processing channel state information provided in an embodiment of the present application, which can be applied to Figure 1 In the first node shown. Figure 3 As shown, the method includes the following S301-S305.

[0104] S301. A first node sends a capability parameter to a second node.

[0105] Among them, the capability parameter includes at least one of the following: the maximum number of reference signal resources L, the maximum number of time periods capable of determining channel state information R. L and R are both positive integers. Of course, the above is only an exemplary description of the capability parameter, and the above capability parameter may also include other information, such as the maximum download rate supported, the maximum upload rate supported, carrier aggregation capability, multi-stream transmission capability, and high-order modulation capability, etc., which are not limited in this application.

[0106] It can be understood that the maximum number L of reference signal resources included in the capability parameter also represents the maximum number of times the first node can receive or measure a reference signal on the same reference signal resource.

[0107] For example, the reference signal on the same reference signal resource is transmitted at different times, that is, the reference signal on the same reference signal resource is transmitted multiple times at different times. The first node receives or measures the reference signals transmitted at different times on the same reference signal resource to estimate future channel state information. It can be seen that the maximum number of reference signal resources L in the capability parameter also indicates the maximum number of times the first node can receive or measure the reference signal on the same reference signal resource.

[0108] Optionally, a channel state information includes at least one of the following information: channel quality indication, precoding matrix. Of course, the above is only an exemplary description of the channel state information, and the channel state information may also include other information, such as reference signal received power, reference signal received quality, the strongest reference signal index or the strongest reference signal resource index, the weakest reference signal index or the weakest reference signal resource index, a reference signal index or a reference signal resource index greater than or equal to a threshold, and a reference signal index or a reference signal resource index less than or equal to a threshold.

[0109] Among them, the strongest reference signal index or the strongest reference signal resource index, the weakest reference signal index or the weakest reference signal resource index, the reference signal index or the reference signal resource index greater than or equal to the threshold, and the reference signal index or the reference signal resource index less than or equal to the threshold are determined according to the reference signal received power or the reference signal received quality.

[0110] Optionally, for other information that may be included in the capability parameters, refer to the embodiments shown in Case 1 to Case 3, which will not be described in detail here.

[0111] It should be noted that the reference signal resources are used to carry reference signals.

[0112] S302: The first node receives configuration information determined by the second node based on capability parameters.

[0113] In a possible implementation manner, the configuration information is used to indicate at least one of the following: K reference signal resources measured by the first node, and N time periods for the first node to report channel state information.

[0114] Wherein, K is a positive integer less than or equal to L, and N is a positive integer less than or equal to R.

[0115] Optionally, other information indicated by the configuration information may refer to the description of the configuration information in S402, which will not be repeated here.

[0116] S303: The first node receives a reference signal based on the configuration information.

[0117] In a possible implementation manner, the first node receives K reference signal resources for carrying a reference signal based on configuration information.

[0118] It can be understood that the largest number of reference signal resources corresponding to the reference signal measured by the first node means that the channel state information determined by the first node is more accurate. The first node measures or receives reference signal resources, which means that the first node measures or receives the reference signal carried by the reference signal resources, that is, the first node receives or measures the reference signal carried on the reference signal resources. The number of reference signal resources measured or received by the first node refers to the number of reference signals carried by the reference signal resources measured or received by the first node.

[0119] Optionally, corresponding to the jth reference signal resource among the reference signal resources indicated by the configuration information being occupied by other signals, the process in which the first node receives the reference signal retransmitted by the second node refers to the embodiment shown in S701 and is not repeated here.

[0120] S304. The first node determines channel state information based on the reference signal and the configuration information.

[0121] In one example, the first node measures K reference signal resources based on configuration information and determines channel state information for N time periods.

[0122] Optionally, corresponding to M reference signal resources among K reference signal resources being occupied by other signals, and the configuration information instructs the first node to determine channel state information for Q time periods, the first node measures KM reference signals and determines channel state information for Q time periods.

[0123] Optionally, corresponding to the jth reference signal resource in the reference signal resources indicated by the configuration information being occupied by other signals, the first node determines the channel state information based on the reference signal retransmitted by the second node. Refer to the embodiment shown in S702 and will not be repeated here.

[0124] S305. The first node reports channel state information.

[0125] The channel state information is the channel state information in a time period. A time period can be a time slot or multiple consecutive time slots. The first node predicts and reports the channel state information, corresponding to predicting and reporting one channel state information in one time period. The first node predicts and reports N channel state information, corresponding to predicting and reporting one channel state information in N time periods.

[0126] In a possible implementation, the first node reports the channel state information of multiple time periods based on frequency domain granularity. Correspondingly, the second node receives the channel state information of multiple time periods based on frequency domain granularity.

[0127] The frequency domain granularity of the channel state information is related to whether any reference signal resource among the K reference signal resources is occupied by other signals.

[0128] In one example, corresponding to the fact that a reference signal resource among the K reference signal resources is occupied by other signals, the frequency domain granularity is the first frequency domain granularity.

[0129] For example, one frequency domain granularity is one subband. The first node may report the channel state information to the second node according to each subband.

[0130] In yet another example, corresponding to the situation where no reference signal resource among the K reference signal resources is occupied by other signals, the frequency domain granularity is the second frequency domain granularity.

[0131] The first frequency domain granularity is greater than the second frequency domain granularity.

[0132] For example, the second frequency domain granularity is two subbands. The first node may report the channel state information to the second node according to every two subbands.

[0133] For another example, the second frequency domain granularity is three subbands. The first node may report the channel state information to the second node according to every three subbands.

[0134] Optionally, the first frequency domain granularity may be X times the second frequency domain granularity, where X is an integer greater than or equal to 2.

[0135] It can be understood that the first node reports the channel state information to the second node according to the frequency domain granularity, and the first node reports the channel state information to the second node according to the frequency domain unit, that is, one channel state information is reported for each frequency domain unit. When some reference signal resources are occupied, the frequency domain unit is adjusted or increased, and the channel state information is reported according to the new frequency domain unit, which can make the reported channel state information more accurate and save resource overhead.

[0136] Optionally, a channel state information is reported corresponding to each frequency domain unit, or a precoding matrix is ​​reported corresponding to each frequency domain unit.

[0137] In another possible implementation, the first node reports the channel state information of multiple time periods based on the number of feedback bits. Correspondingly, the second node receives the channel state information of multiple time periods based on the number of feedback bits.

[0138] The number of feedback bits of the channel state information is related to whether any reference signal resource among the K reference signal resources is occupied by other signals.

[0139] In an example, corresponding to the fact that a reference signal resource among the K reference signal resources is occupied by other signals, the number of feedback bits is the first number of feedback bits.

[0140] For example, taking the channel state information as a channel quality indicator, the first node reports the channel quality indicator to the second node according to the first number of feedback bits.

[0141] For another example, taking the channel state information as a precoding matrix, the first node reports the precoding matrix to the second node according to the first number of feedback bits.

[0142] For another example, taking the channel state information as received power, the first node reports the received power to the second node according to the first number of feedback bits.

[0143] In another example, corresponding to the situation where no reference signal resource among the K reference signal resources is occupied by other signals, the number of feedback bits is the second number of feedback bits, and the first number of feedback bits is greater than the second number of feedback bits.

[0144] For example, taking the channel state information as a channel quality indicator, the first node reports the channel quality indicator to the second node according to the second feedback bit number.

[0145] For another example, taking the channel state information as a precoding matrix, the first node reports the precoding matrix to the second node according to the second number of feedback bits.

[0146] For another example, taking the channel state information as received power, the first node reports the received power to the second node according to the second number of feedback bits.

[0147] It is understandable that, when some reference signal resources are occupied, using the original number of feedback bits to report channel state information will result in a waste of resources. Reporting channel state information by using a smaller number of feedback bits can save resource overhead.

[0148] It is understandable that the second node determines the data transmission strategy based on the channel state information sent by the first node, which can effectively improve the performance of data transmission. In addition, the second node obtains the channel state information of multiple time periods from the first node, where more time periods mean more far-reaching channel state information in the future, so that the data transmission strategy determined by the second node can more efficiently and accurately schedule future data services to improve the performance of the communication system.

[0149] Optionally, corresponding to the fact that part of the reference signal resources indicated by the configuration information are occupied by other signals, the specific process of the first node reporting the channel state information of Q time periods refers to the embodiment shown in S501 and will not be repeated here.

[0150] Optionally, after the j-th reference signal resource among the reference signal resources indicated by the configuration information is occupied by other signals and the second node retransmits the reference signal, the process in which the first node continues to report the channel state information associated with the configuration information refers to the embodiment shown in S703 and is not repeated here.

[0151] Based on the above technical solution, the present application provides a method for processing channel state information, in which the first node sends a capability parameter to the second node. By sending the capability parameter to the second node, the first node can enable the second node to configure the configuration information that matches the capability parameter for the first node. The first node receives the configuration information from the second node, and receives a reference signal that matches the capability of the first node based on the configuration information to avoid receiving too many or too few reference signals; thereby enabling the first node to receive and process reference signal resources that match its own capabilities. Furthermore, the first node reports the channel state information to the second node.

[0152] The above technical solution can solve the problem of resource waste caused in the process of acquiring channel state information, and can configure the first node with configuration information that matches its own capabilities, thereby improving resource utilization.

[0153] Moreover, in the above technical solution, the first node determines the channel state information of the time period adapted to the capability of the first node based on the configuration information to avoid determining the channel state information of too many or too few time periods; thereby enabling the first node to process the channel state information of the time period adapted to its own capability.

[0154] It can be seen from this that the above technical solution can also solve the problems of communication system crash caused by the current process of obtaining channel state information and the decrease in the quality and quantity of the obtained channel state information, improve the quality and quantity of the obtained channel state information, and prevent the communication system crash caused by the process of obtaining channel state information.

[0155] Figure 4 A flowchart of another method for processing channel state information provided in an embodiment of the present application, which can be applied to Figure 1 In the second node shown. Figure 4 As shown, the method includes the following S401-S405.

[0156] S401: A second node receives a capability parameter from a first node.

[0157] Among them, the capability parameter includes at least one of the following: the maximum number of reference signal resources L, the maximum number of time periods capable of determining channel state information R. L and R are both positive integers. Of course, the above is only an exemplary description of the capability parameter, and the above capability parameter may also include other information, such as the maximum download rate supported, the maximum upload rate supported, carrier aggregation capability, multi-stream transmission capability, and high-order modulation capability, etc., which are not limited in this application.

[0158] Optionally, other information included in the capability parameter may refer to the description of the capability parameter in S301, which will not be described again here.

[0159] S402: The second node determines configuration information based on capability parameter configuration.

[0160] In a possible implementation manner, the configuration information is used to indicate at least one of the following: K reference signal resources measured by the first node, and N time periods for the first node to report channel state information.

[0161] Wherein, K is a positive integer less than or equal to L, and N is a positive integer less than or equal to R.

[0162] Optionally, the K reference signal resources measured by the first node indicated in the configuration information also indicate that the first node measures the reference signal on the same reference signal resource K times, each time corresponding to a reference signal transmitted at a different time or in a different frequency domain.

[0163] It can be understood that the second node instructs the first node through configuration information that the number K of reference signal resources measured by the first node is less than or equal to the maximum number L of reference signal resources measured by the first node, thereby avoiding the second node configuring too many reference signal resources for the first node, thereby causing resource waste or causing the first node to crash.

[0164] On the contrary, when the second node instructs the first node through configuration information that the number K of reference signal resources to be measured is greater than the maximum number L of reference signal resources measured by the first node, on the one hand, the first node will not be able to effectively utilize the L reference signal resources due to its own capability limitations, thereby causing a waste of reference signal resources; on the other hand, the first node receives or measures reference signals beyond its own capability range, which may cause the first node to crash, and then cause the second communication node to crash.

[0165] It can be understood that the second node configures the number K of measurement reference signal resources for the first node according to the maximum number L of measurement reference signal resources of the first node indicated by the capability parameter and its own needs. When K is less than or equal to L, the value of K also needs to meet the number of reference signal resources required by the second node itself as much as possible. The second node indicates through configuration information that the number K of measurement reference signal resources of the first node is less than or equal to the maximum number L of measurement reference signal resources of the first node, thereby avoiding the second node from configuring too few reference signal resources for the first node on the basis of avoiding the second node from configuring too many reference signal resources for the first node.

[0166] On the contrary, when the second node is unknown about the capability parameters of the first node, in order to ensure the normal operation of the first node, the second node will configure a very small number of reference signal resources that deviates from its own needs, thereby losing the accuracy of the obtained channel state information.

[0167] It can be understood that the second node indicates through configuration information that the number N of time periods for the first node to report channel state information is less than or equal to the maximum number R of time periods for the first node to determine channel state information, thereby avoiding the second node requiring the first node to determine too many time periods for channel state information, causing the first node to crash.

[0168] On the contrary, when the number N of time periods in which the second node indicates through configuration information that the first node reports channel state information is greater than the maximum number R of time periods for which the first node can determine channel state information, on the one hand, the first node cannot estimate or predict the channel state information of N time periods due to its own capability limitations, and cannot meet the needs of the second node; on the other hand, the first node estimates or predicts the channel state information of time periods exceeding its own capability, which may cause the first node to crash, and then cause the second node to crash.

[0169] It can be understood that the second node configures the number N of time periods for reporting channel state information for the first node based on the maximum number R of time periods for the first node to determine channel state information indicated by the capability parameter and its own needs. In the case where N is less than or equal to R, the value of N also needs to meet the number of time periods for channel state information required by the second node itself as much as possible. The second node instructs the first node through configuration information to configure the number N of time periods for reporting channel state information to be less than or equal to the maximum number R of time periods for the first node to determine channel state information, thereby avoiding the second node requiring the first node to determine too few time periods for channel state information on the basis of avoiding the second node requiring the first node to determine too many time periods for channel state information.

[0170] On the contrary, when the second node is unaware of the maximum number R of time periods during which the first node can determine the channel state information, in order to ensure the normal operation of the first node, the second node will configure a number of time periods that deviates from its own needs, that is, a very small number of channel state information, thereby losing a profound degree of control over future channel state information.

[0171] In another possible implementation, the above is only an exemplary description of the configuration information, and the above configuration information may also be used to indicate other information. For example, the configuration information may also be used to indicate any of the following:

[0172] In the case where part of the reference signal resources indicated by the configuration information are occupied by other signals, the first node continues to report the channel state information related to the configuration information; in the case where part of the reference signal resources indicated by the configuration information are occupied by other signals, the first node no longer reports the channel state information related to the configuration information, and this application does not limit this.

[0173] For example, the second node instructs the first node through configuration information to continue reporting channel state information related to the configuration information based on the capability parameters of the first node and the second node's own needs, so as to make full use of other reference signal resources and achieve consistent collaboration between the first node and the second node to avoid system crash.

[0174] For another example, the second node instructs the first node through configuration information to stop reporting channel state information related to the configuration information based on the capability parameters of the first node and the needs of the second node itself, so as to save unnecessary reporting overhead of the first node to the second node, achieve consistent collaboration between the first node and the second node, avoid system crashes, and reduce resource waste.

[0175] S403: The second node sends configuration information to the first node.

[0176] In a possible implementation manner, the second node sends, to the first node, K reference signal resources used for measurement by the first node, and / or configuration information of N time periods for the first node to report channel state information.

[0177] S404: The second node transmits a reference signal based on the configuration information.

[0178] In a possible implementation manner, based on the configuration information, the second node sends K reference signal resources for carrying the reference signal to the first node.

[0179] It can be understood that the more reference signal resources the second node sends to the first node, that is, the greater the number of reference signal resources corresponding to the reference signal measured by the first node, the more accurate the channel state information determined by the first node. The first node measures or receives reference signal resources, which means that the first node measures or receives the reference signal carried by the reference signal resources, that is, the first node receives or measures the reference signal carried on the reference signal resources. The number of reference signal resources measured or received by the first node refers to the number of reference signals carried by the reference signal resources measured or received by the first node.

[0180] Optionally, corresponding to the jth reference signal resource among the reference signal resources indicated by the configuration information being occupied by other signals, the process in which the second node retransmits the reference signal may refer to the embodiment shown in S801 and will not be described in detail here.

[0181] S405: The second node receives channel state information.

[0182] The channel state information is the channel state information in a time period. A time period can be a time slot or multiple consecutive time slots. The first node predicts and reports the channel state information, corresponding to predicting and reporting one channel state information in one time period. The first node predicts and reports N channel state information, corresponding to predicting and reporting one channel state information in N time periods.

[0183] In a possible implementation manner, the second node receives channel state information of multiple time periods based on frequency domain granularity.

[0184] The frequency domain granularity of the channel state information is related to whether any reference signal resource among the K reference signal resources is occupied by other signals.

[0185] In one example, corresponding to the fact that a reference signal resource among the K reference signal resources is occupied by other signals, the frequency domain granularity is the first frequency domain granularity.

[0186] For example, one frequency domain granularity is one subband. The second node may receive the channel state information from the first node according to each subband.

[0187] In yet another example, corresponding to the situation where no reference signal resource among the K reference signal resources is occupied by other signals, the frequency domain granularity is the second frequency domain granularity.

[0188] The first frequency domain granularity is greater than the second frequency domain granularity.

[0189] For example, the second frequency domain granularity is two subbands. The second node may receive the channel state information from the first node according to every two subbands.

[0190] For another example, the second frequency domain granularity is three subbands. The first node may report the channel state information to the second node according to every three subbands.

[0191] Optionally, the first frequency domain granularity may be X times the second frequency domain granularity, where X is an integer greater than or equal to 2.

[0192] It is understandable that the second node can receive the channel state information from the first node according to the frequency domain granularity, and the second node can receive the channel state information from the first node according to the frequency domain unit, that is, one channel state information is received for each frequency domain unit. When some reference signal resources are occupied, adjusting or increasing the frequency domain unit and receiving the channel state information reported by the first node according to the new frequency domain unit can make the received channel state information more accurate and save resource overhead.

[0193] Optionally, a channel state information is reported corresponding to each frequency domain unit, or a precoding matrix is ​​reported corresponding to each frequency domain unit.

[0194] In another possible implementation manner, the second node receives channel state information of multiple time periods based on the number of feedback bits.

[0195] The number of feedback bits of the channel state information is related to whether any reference signal resource among the K reference signal resources is occupied by other signals.

[0196] In an example, corresponding to the fact that a reference signal resource among the K reference signal resources is occupied by other signals, the number of feedback bits is the first number of feedback bits.

[0197] For example, taking the channel state information as a channel quality indicator, the second node receives the channel quality indicator from the first node according to the first feedback bit number.

[0198] For another example, taking the channel state information as a precoding matrix, the second node receives the precoding matrix from the first node according to the first number of feedback bits.

[0199] For another example, taking the channel state information as the received power as an example, the second node receives the received power from the first node according to the first number of feedback bits.

[0200] In another example, corresponding to the situation where no reference signal resource among the K reference signal resources is occupied by other signals, the number of feedback bits is the second number of feedback bits, and the first number of feedback bits is greater than the second number of feedback bits.

[0201] For example, taking the channel state information as a channel quality indicator, the second node receives the channel quality indicator from the first node according to the second number of feedback bits.

[0202] For another example, taking the channel state information as a precoding matrix, the second node receives the precoding matrix from the first node according to the second number of feedback bits.

[0203] For another example, taking the channel state information as the received power as an example, the second node receives the received power from the first node according to the second number of feedback bits.

[0204] It is understandable that, when some reference signal resources are occupied, using the original number of feedback bits to report channel state information will result in a waste of resources. Receiving channel state information with a smaller number of feedback bits can save resource overhead.

[0205] It is understandable that the second node determines the data transmission strategy based on the channel state information sent by the first node, which can effectively improve the performance of data transmission. In addition, the second node obtains the channel state information of multiple time periods from the first node, where more time periods mean more far-reaching channel state information in the future, so that the data transmission strategy determined by the second node can more efficiently and accurately schedule future data services to improve the performance of the communication system.

[0206] Optionally, corresponding to the fact that part of the reference signal resources indicated by the configuration information are occupied by other signals, the specific process of the second node receiving the channel state information of Q time periods refers to the embodiment shown in S601 and will not be repeated here.

[0207] Optionally, after the j-th reference signal resource among the reference signal resources indicated by the configuration information is occupied by other signals and the second node retransmits the reference signal, the process in which the second node receives channel state information associated with the configuration information continued to be reported from the first node refers to the embodiment shown in S802 and will not be repeated here.

[0208] Based on the above technical solution, the present application provides a method for processing channel state information, in which the second node receives a capability parameter from the first node. Since the capability parameter includes the maximum number of reference signal resources, and / or the maximum number of time periods for determining the channel state information. Based on the capability parameter, the second node can configure the configuration information that is adapted to the capability parameter for the first node. The second node sends configuration information to the first node, and based on the configuration information, transmits a reference signal that is adapted to the capability of the first node to avoid sending too many or too few reference signals to the first node. The second node receives the channel state information. The above technical solution can solve the problem that when the amount of measurement is too large, the terminal device can only measure the channel state information of part of the time within its own capability range, and cannot make full use of multiple reference signals at different times, which will cause a waste of resources, and effectively improve resource utilization.

[0209] In addition, in wireless communication scenarios, urgent and important services may suddenly occur, so that the signal serving this service will occupy part of the reference signal resources in the reference signal resources. When some reference signal resources are occupied, the terminal device usually does not have the ability to predict the measurement conditions indicated by the original configuration information. When the original measurement conditions change, for example, some pre-configured reference signal resources are occupied, the terminal device cannot receive some reference signals pre-configured by the access network device, and the terminal device and the access network device do not know each other's execution actions. For example, the terminal device predicts and reports the channel state, but does not have the originally predetermined measurement conditions. The access network device does not know whether the terminal device has the ability to predict and report the channel state information when the original measurement conditions change; or, the terminal device continues to report the channel state information, and the access network device does not think that the terminal device will continue to report the channel state information; or, the terminal device no longer reports the channel state information, and the access network device thinks that the terminal device will continue to report the channel state information. The loss of coordination between the actions of the terminal device and the access network device will also cause the communication system to collapse and waste resources.

[0210] The signal that seizes the reference signal resource includes one of the following: a data demodulation reference signal, a data signal, a synchronization signal, a broadcast signal, an uplink subframe signal, and the like.

[0211] Furthermore, if the terminal device does not predict and report the channel status, unoccupied reference signal resources will be wasted, resulting in a problem of resource waste.

[0212] As a possible embodiment of the present application, the capability parameter in the above S301 may also include information shown in at least one of the following three situations, namely, situation 1, the capability parameter may also include indication information for indicating whether the first node has the ability to report channel state information; situation 2, the capability parameter may also include indication information for indicating the relative relationship between K and M; situation 3, the capability parameter may also include indication information for indicating the number and position of P values; the following are detailed descriptions respectively.

[0213] Case 1: the capability parameter may also include indication information for indicating whether the first node has the capability of reporting the channel state information.

[0214] In some embodiments, the indication information used to indicate whether the first node has the ability to report the channel state information includes: first indication information, second indication information, or third indication information.

[0215] The first indication information is used to indicate whether the first node has the ability to report channel state information when part of the reference signal resources indicated by the configuration information are occupied by other signals.

[0216] In one example, some of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, and some first nodes have the ability to report channel state information, but some first nodes do not have the ability to report channel state information. Both of the above two devices will add information about whether they have this ability to the capability parameter.

[0217] The first node can indicate to the second node whether it has the ability to report channel state information through capability parameters, so that the second node, knowing the capability of the first node, can instruct the first node to continue to report channel state information or perform the default configuration so that the first node and the second node can cooperate in a consistent manner, thereby avoiding system crashes on both sides and reducing waste of resources.

[0218] Optionally, corresponding to the first node having the ability to report channel state information, the second node may instruct the first node to continue reporting the channel state information or instruct the first node to stop reporting the channel state information through configuration information according to its own needs.

[0219] Alternatively, corresponding to the first node having the ability to report channel state information, the second node may not instruct the first node to continue reporting the channel state information. In this case, the first node and the second node may both unanimously determine that the first node continues to report the channel state information; or the first node and the second node may both unanimously determine that the first node does not continue to report the channel state information, and this application does not limit this.

[0220] Optionally, corresponding to the first node not having the ability to report channel state information, the first node informs the second node through the capability parameter that it does not have the ability to continue reporting channel state information. At this time, the second node can infer the behavior of the first node based on the capability parameter of the first node, for example, the first node stops reporting channel state information.

[0221] The second indication information is used to indicate that the first node has the capability of reporting channel state information when part of the reference signal resources indicated by the configuration information are occupied by other signals.

[0222] In one example, part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, and some first nodes have the ability to report channel state information, but some first nodes do not have the ability to report channel state information. For the first node that has the ability to report channel state information, the information that it has the ability will be added to the capability parameter. For the first node that does not have the ability to report channel state information, the information that it does not have the ability will not be added to the capability parameter.

[0223] For a first node that has the ability to report channel state information, the first node can indicate to the second node through a capability parameter that it has the ability to report channel state information, so that the second node, knowing the capability of the first node, can instruct the first node to continue reporting the channel state information or instruct the first node to stop reporting the channel state information, so that the first node and the second node can act in a coordinated manner, avoid system crashes on both sides, and reduce waste of resources.

[0224] Alternatively, corresponding to the first node having the ability to report channel state information, the second node may not instruct the first node to continue to report the channel state information. In this case, the first node and the second node may both unanimously determine that the first node will continue to report the channel state information; or, the first node and the second node may both unanimously determine that the first node will not continue to report the channel state information, and the present application does not limit this.

[0225] The third indication information is used to indicate that the first node does not have the ability to report channel state information when part of the reference signal resources indicated by the configuration information are occupied by other signals.

[0226] For the first node that does not have the ability to report channel state information, the first node does not report its own ability to the second node. In this case, the second node believes that the node that does not send the ability to the second node will not continue to report the channel state information, so that the first node and the second node can cooperate in a consistent manner, avoid system crashes on both sides, and reduce waste of resources.

[0227] It should be noted that if the first node that has the ability to report channel state information and the first node that does not have the ability to report channel state information do not send the first node's ability to report channel state information to the second node, then the second node cannot distinguish between the two nodes. As a result, the actions of the first node and the second node are out of coordination, for example, the first node continues to report channel state information, but the second node does not think that the first communication node will continue to report channel state information; or the first node no longer reports channel state information, but the second communication node thinks that the first node will continue to report channel state information, causing the communication system to collapse and waste resources.

[0228] Case 2: The capability parameter in S301 may also include at least one of the following:

[0229] The minimum value of K; the possible values ​​of K; the maximum value of M; the possible values ​​of M; the relative relationship between K and M; the ratio of M to K; the maximum value of the ratio; the possible values ​​of the ratio; the positional relationship between the M reference signal resources among the K reference signal resources.

[0230] Wherein, M is the number of reference signal resources occupied by other signals among the K reference signal resources, and M is a positive integer. The position relationship includes at least one of a time sequence position, a frequency domain sequence position, a space sequence position, and a configuration sequence position.

[0231] In a possible implementation, corresponding to M reference signal resources among K reference signal resources being occupied by other signals, the first node has the ability to report channel state information only when K or (and) M meet certain conditions.

[0232] The following is a detailed introduction to certain conditions that K or (and) M satisfy.

[0233] In one example, the capability parameter of the first node includes a minimum value of K, that is, K indicated by the configuration information is greater than or equal to the minimum value of K, and the first node has the ability to report channel state information.

[0234] In another example, the capability parameter of the first node includes possible values ​​of K, that is, when K indicated by the configuration information is within a possible value range of K, the first node has the capability of reporting channel state information.

[0235] In another example, the capability parameter of the first node includes a maximum value of M, that is, corresponding to M indicated by the configuration information being less than or equal to the maximum value of M, the first node has the capability to report channel state information.

[0236] In another example, the capability parameter of the first node includes possible values ​​of M, that is, when M indicated by the configuration information is within a possible value range of M, the first node has the capability to report channel state information.

[0237] In another example, the capability parameter of the first node includes a relative relationship between K and M, that is, K and M indicated by the configuration information satisfy the relative relationship, and the first node has the capability to report channel state information.

[0238] For example, the relative relationship between K and M can be: K and M are listed one by one. For example, K is 10, 20, 30; M is 3, 5, 6.

[0239] For another example, the relative relationship between K and M can also be: K and M are listed in pairs, such as: K is 10, M is 3; or, K is 20, M is 3.

[0240] For another example, the relative relationship between K and M may also be: M is less than or equal to a proportional part of K. For example, M is less than or equal to 1 / 2 of K, or M is less than or equal to 1 / 3 of K.

[0241] For another example, the relative relationship between K and M can also be: K is greater than or equal to the product of M and a proportional coefficient. For example, K is greater than or equal to 2 times of M, or K is greater than or equal to 3 times of M, or K is greater than or equal to the product of M and α. Where α is greater than 1.

[0242] In another example, the capability parameters of the first node include the ratio of M to K and the maximum value of the ratio, or the ratio of M to K and the possible values ​​of the ratio, that is, when the ratio of K to M indicated by the configuration information meets the maximum value or the minimum value, the first node has the ability to report channel state information.

[0243] For example, the first communication node indicates the ratio of M to K and the maximum value of the ratio, that is, the ratio of M to K indicated by the configuration information is less than or equal to the maximum value of the ratio, and the first communication node has the ability to report channel state information.

[0244] For another example, the capability parameters of the first node include the ratio of M to K and the possible values ​​of the ratio, that is, the ratio of M to K indicated by the configuration information is within the possible values ​​of the ratio, and the first node has the ability to report channel state information.

[0245] In another example, the capability parameters of the first node include a positional relationship among M reference signal resources among K reference signal resources, that is, the positions of the M reference signal resources among the K reference signal resources indicated by the configuration information should satisfy this positional relationship, and the first node has the ability to report channel state information.

[0246] The position relationship includes at least one of a time sequence position, a frequency domain sequence position, a space sequence position and a configuration sequence position.

[0247] Case 3: The capability parameter in S301 may also include at least one of the following:

[0248] The possible values ​​of P; the maximum value of P; the position of P time periods in N time periods.

[0249] The P time periods are time periods during which the first node reports channel state information when part of the reference signal resources indicated by the configuration information are occupied by other signals.

[0250] In a possible implementation manner, corresponding to M reference signal resources among K reference signal resources being occupied by other signals, the first node determines to report channel state information of P time periods.

[0251] Among them, the P indicated by the configuration information should be within the possible value range of P, so that the first node can report the channel state information of P time periods.

[0252] In one example, the capability parameter of the first node includes a maximum value of P, that is, corresponding to P indicated by the configuration information being less than or equal to the maximum value of P, the first node reports channel state information for P time periods.

[0253] In another example, the capability parameter of the first node includes possible values ​​of P, that is, corresponding to P indicated by the configuration information being within a possible value interval of P, the first node reports channel state information for P time periods.

[0254] In another example, the capability parameter of the first node includes the position of P time periods in N time periods, that is, the position of the P time periods indicated by the configuration information satisfies the position of the P time periods in N time periods indicated by the capability parameter, and the first communication node reports the channel state information of the P time periods.

[0255] It is understandable that, corresponding to M reference signal resources among K reference signal resources being occupied by other signals, the amount of channel state information that can be reported by the corresponding first node is affected, for example, negatively correlated with the number of reference signal resources occupied by other signals.

[0256] It should be noted that the capability parameter may include the information shown in the above three situations at the same time, or may include the information shown in only one of the situations, or may include the information shown in any two of the situations, and this application does not limit this.

[0257] Based on the above technical solution, the above technical solution shows whether the first node has the ability to report channel state information when some of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, as well as the relative relationship between the number of occupied reference signal resources and the time period of the channel state information that the first node can determine, so as to facilitate the second node to determine the execution action of the first node according to the capability parameters reported by the first node, thereby ensuring the consistency of the actions of both nodes, avoiding system crashes and reducing resource waste.

[0258] As a possible embodiment of the present application, Figure 3 ,like Figure 5 As shown, corresponding to the fact that part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, the process of the first node reporting the channel state information in the above S305 can also be implemented through the following S501.

[0259] S501. A first node reports channel state information of Q time periods.

[0260] Wherein, Q is a positive integer less than or equal to N.

[0261] The value of Q is specifically introduced below.

[0262] In a possible implementation, the value of Q is determined according to the value of M.

[0263] Wherein, M is the number of reference signal resources occupied by other signals among the K reference signal resources, and M is a positive integer.

[0264] In some embodiments, the value of Q can be determined according to any one of the following methods 1-4, namely: Method 1, the value of Q is determined according to the value of M; Method 2, the value of Q is specifically determined based on K and M; Method 3, the value of Q is specifically determined based on M and N; Method 4, the value of Q is specifically determined based on M, K and N; each of which is described in detail below.

[0265] Method 1: The value of Q is determined according to the value of M.

[0266] For example, the value of Q is NM, and the value of Q decreases as M increases. More specifically, when the value of M is 1, the value of Q is N-1; when the value of M is 2, the value of Q is N-2.

[0267] Method 2: The value of Q is determined based on K and M.

[0268] Optionally, the ratio of M to K represents the influence of a portion of the reference signal resources occupied by other signals on the predicted channel state information. Therefore, the value of Q can be determined according to the ratio of M to K.

[0269] For example, Q is determined by M / K, Q=N(1-M / K).

[0270] Here, N(1-M / K) represents the product of N and 1-M / K.

[0271] Optionally, the ratio of KM to K represents the influence of reference signal resources not occupied by other signals on the predicted channel state information. Therefore, the value of Q can be determined according to the ratio of KM to K.

[0272] For example, Q is determined by (KM) / K, Q=N(KM) / K.

[0273] Here, N(KM) / K represents the product of N and (KM) / K.

[0274] Method 3: The value of Q is determined based on M and N.

[0275] Optionally, the value of Q is the integer of N minus a times M. For example, Q is N-[aM].

[0276] Among them, [] is a symbol representing rounding operation.

[0277] Optionally, the value of Q is N minus the integer of a times M minus b. For example, Q is N-[aM]-b.

[0278] Wherein, b is an integer.

[0279] Method 4: The value of Q is determined based on M, K and N.

[0280] Optionally, the value of Q is the smaller value between KM and N. For example, Q is min(KM,N).

[0281] Among them, min means taking the smaller value in the input data.

[0282] Optionally, Q is the integer value of the product of N and 1-M / K.

[0283] Optionally, Q is the integer value of the product of N and 1-M / K, a.

[0284] Optionally, Q is the integer value of the product of N and (KM) / K.

[0285] Optionally, Q is the integer value of the product of N and (KM) / K, a.

[0286] Where a is a non-negative real number and / is a division sign.

[0287] The above is a detailed introduction to the value of Q. The following is a detailed introduction to the positions of the Q time periods.

[0288] In a possible implementation manner, the positions of the Q time periods are determined according to the position of the first reference signal resource among the M reference signal resources.

[0289] In one example, the position of the first time period in the Q time periods in the N time periods is associated with the position of the first reference signal resource in the M reference signal resources in the K reference signal resources. That is, the position of the first time period in the Q time periods in the N time periods can be determined according to the position of the first reference signal resource in the M reference signal resources in the K reference signal resources.

[0290] In another example, the position of the first reference signal resource among the M reference signal resources among the K reference signal resources corresponds to the position of the first time period among the Q time periods among the N time periods.

[0291] That is, the position of the first reference signal resource among the M reference signal resources in the K reference signal resources may be mapped to the position of the first time period among the Q time periods in the N time periods.

[0292] For example, the offset between the starting point of the Q time periods and the starting point of the N time periods is equal to the offset between the starting point of the M reference signal resources and the starting point of the K reference signal resources.

[0293] That is, the offsets of the starting points of the Q time periods relative to the starting points of the N time periods may be determined by determining the offsets of the starting points of the M reference signal resources relative to the starting points of the K reference signal resources.

[0294] For another example, a first ratio of the offset between the start point of Q time periods and the start point of N time periods to the length of the N time periods is equal to a second ratio of the offset between the start point of M reference signal resources and the start point of K reference signal resources to the time length of the K reference signal resources.

[0295] The above is a detailed introduction to the positions of Q time periods.

[0296] Based on the above technical solution, the first node reports the channel state information of Q time periods. Corresponding to the fact that part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, the measurement conditions of the N time periods originally reported by the first node have changed, and the number of time periods for which the first node reports the channel state information should be flexibly changed to adapt to the changed measurement conditions. In the above technical solution, the first node reports the channel state information of Q time periods less than or equal to N to ensure the quality of the estimated or predicted channel state information and avoid unnecessary reporting resource overhead.

[0297] As a possible embodiment of the present application, Figure 4 ,like Figure 6 As shown, corresponding to the fact that part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, the process of the second node receiving the channel state information in the above S405 can also be implemented through the following S601.

[0298] S601. The second node receives channel state information of Q time periods.

[0299] Wherein, Q is a positive integer less than or equal to N.

[0300] Optionally, a specific introduction to the value of Q may be made by referring to the description of the value of Q in S501, which will not be repeated here.

[0301] Based on the above technical solution, the second node receives channel state information of Q time periods.

[0302] As a possible embodiment of the present application, Figure 3 ,like Figure 7 As shown, corresponding to the j-th reference signal resource in the reference signal resources indicated by the configuration information being occupied by other signals, after the above S303, the process of the first node receiving the retransmitted reference signal can also be implemented through the following S701.

[0303] S701. A first node receives a retransmitted reference signal.

[0304] In some embodiments, the reference signal can be retransmitted through any one of the following examples 1-3, which are: Example 1, the transmission resources occupied by the retransmitted reference signal are located in the adjacent time slot of the j-th reference signal resource; Example 2, the transmission resources occupied by the retransmitted reference signal are located after the last reference signal resource among K reference signal resources in the time domain; Example 3, the reference signal on K reference signal resources is retransmitted after the j-th reference signal resource; each of which is described in detail below.

[0305] Example 1: The transmission resource occupied by the retransmitted reference signal is located in the adjacent time slot of the j-th reference signal resource.

[0306] For example, the first node receives the retransmitted affected reference signal in the adjacent time slot (j+1) of the original j-th reference signal resource, which can timely compensate for the performance loss caused by the original j-th reference signal resource being occupied by other signals.

[0307] Optionally, all resources after the original j-th reference signal resource are transmitted one time slot later in sequence.

[0308] Example 2: The transmission resource occupied by the retransmitted reference signal is located after the last reference signal resource among the K reference signal resources in the time domain.

[0309] For example, in the time slot after the last reference signal resource among the K reference signal resources, the first node receives the retransmitted j-th reference signal resource so as to retransmit the reference signal through the available reference signal resources, thereby timely compensating for the performance loss caused by the original j-th reference signal resource being occupied by other signals.

[0310] Example 3: The reference signals on K reference signal resources are retransmitted after the jth reference signal resource.

[0311] For example, after the jth reference signal resource, the first node receives K retransmitted reference signal resources, thereby preserving the relative positions of the K reference signal resources to eliminate the performance loss caused by the original jth reference signal resource being occupied by other signals.

[0312] In another example, the reference signal is retransmitted after the j-th reference signal resource is no longer occupied by other signals.

[0313] For example, after the jth reference signal resource is no longer occupied by other signals, the first node continues to receive the retransmitted reference signal through the jth reference signal resource.

[0314] Based on the above technical solution, the first node receives the retransmitted reference signal, which solves the loss caused by part of the reference signal resources being occupied by other signals due to emergencies.

[0315] As a possible embodiment of the present application, Figure 4 ,like Figure 8 As shown, corresponding to the jth reference signal resource in the reference signal resources indicated by the configuration information being occupied by other signals, after the above S404, the process of the second node retransmitting the reference signal can also be implemented through the following S801.

[0316] S801. The second node retransmits a reference signal.

[0317] In some embodiments, the reference signal can be retransmitted through the following Examples 1-3, which are respectively: Example 1, the transmission resources occupied by the retransmitted reference signal are located in the adjacent time slot of the j-th reference signal resource; Example 2, the transmission resources occupied by the retransmitted reference signal are located after the last reference signal resource among the K reference signal resources in the time domain; Example 3, the reference signal on the K reference signal resources is retransmitted after the j-th reference signal resource; each is described in detail below.

[0318] In one example, the transmission resource occupied by the retransmitted reference signal is located in a time slot adjacent to the j-th reference signal resource.

[0319] For example, in the adjacent time slot (j+1) of the original j-th reference signal resource, the second node retransmits the affected reference signal, which can timely compensate for the performance loss caused by the original j-th reference signal resource being occupied by other signals.

[0320] Optionally, all resources after the original j-th reference signal resource are transmitted one time slot later in sequence.

[0321] In another example, the transmission resource occupied by the retransmitted reference signal is located after the last reference signal resource among the K reference signal resources in the time domain.

[0322] For example, in the time slot after the last reference signal resource among the K reference signal resources, the second node retransmits the jth reference signal resource so as to retransmit the reference signal through the available reference signal resources, thereby timely compensating for the performance loss caused by the original jth reference signal resource being occupied by other signals.

[0323] In another example, the reference signals on K reference signal resources are retransmitted after the jth reference signal resource.

[0324] For example, after the jth reference signal resource, the second node retransmits K reference signal resources, thereby preserving the relative positions of the K reference signal resources to eliminate the performance loss caused by the original jth reference signal resource being occupied by other signals.

[0325] In another example, the reference signal is retransmitted after the j-th reference signal resource is no longer occupied by other signals.

[0326] For example, after the j-th reference signal resource is no longer occupied by other signals, the reference signal is continuously retransmitted through the j-th reference signal resource.

[0327] Based on the above technical solution, the second node retransmits the reference signal, thereby solving the problem of loss caused by some reference signal resources being occupied by other signals due to emergencies.

[0328] As a possible embodiment of the present application, Figure 7 As shown, the process of the first node determining the channel state information in the above S304 can also be implemented through the following S702.

[0329] S702. The first node determines channel state information based on the retransmitted reference signal.

[0330] In one example, the configuration information indicates K reference signal resources measured by the first node and N time periods for the first node to report channel state information. The first node measures the K reference signal resources based on the K reference signals retransmitted by the second node, and determines the channel state information of the N time periods.

[0331] In another example, the first node may determine the channel state information of a part of the time period in real time based on the reference signal transmitted by the second node, and re-determine the remaining channel state information after the second node retransmits the jth reference signal resource.

[0332] Based on the above technical solution, the first node determines the channel state information based on the retransmitted reference signal. The above technical solution can effectively utilize the retransmitted reference signal and greatly ensure the accuracy of the channel state information.

[0333] As a possible embodiment of the present application, Figure 7 As shown, the process of the first node reporting the channel state information in the above S305 can also be implemented through the following S703.

[0334] S703: The first node continues to report the channel state information associated with the configuration information.

[0335] In one example, the configuration information indicates K reference signal resources measured by the first node and N time periods for the first node to report channel state information. The first node measures K reference signal resources based on the K reference signals retransmitted by the second node, and reports channel state information for N time periods.

[0336] In another example, the first node can determine the channel state information of a part of the time period in real time based on the reference signal transmitted by the second node, and send the part of the channel state information to the second node. After the second node retransmits the jth reference signal resource, the remaining channel state information is re-determined and uploaded.

[0337] Based on the above technical solution, the first node continues to report the channel state information associated with the configuration information. By measuring the reference signal resources transmitted or received in the new time slot, the problem of missing the time period of the channel state information caused by the destruction of the original prediction condition can be effectively solved, and the quality or accuracy of the predicted channel state information is guaranteed.

[0338] As a possible embodiment of the present application, Figure 8 As shown, the process of the second node receiving the channel state information in the above S405 can also be implemented through the following S802.

[0339] S802: The second node continues to receive channel state information associated with the configuration information.

[0340] In one example, the configuration information indicates K reference signal resources measured by the first node and N time periods for the first node to report channel state information. The second node receives K reference signals from the first node after retransmission, measures K reference signal resources, and reports channel state information for N time periods.

[0341] In another example, the second node may receive a reference signal transmitted by the second node in real time from the first node to determine the channel state information for a portion of the time period. After the second node retransmits the jth reference signal resource, the second node may receive the remaining channel state information from the first node again to re-determine and upload.

[0342] Based on the above technical solution, the second node continues to receive the channel state information associated with the configuration information. By measuring the reference signal resources transmitted or received in the new time slot, the problem of missing the time period of the channel state information caused by the destruction of the original prediction condition can be effectively solved, and the quality or accuracy of the predicted channel state information is guaranteed.

[0343] The embodiment of the present application can divide the communication device into functional modules or functional units according to the above method example. For example, each functional module or functional unit can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules or functional units. Among them, the division of modules or units in the embodiment of the present application is schematic, which is only a logical function division, and there may be other division methods in actual implementation.

[0344] Through the description of the above implementation methods, technicians in the relevant field can clearly understand that for the convenience and simplicity of description, only the division of the above functional modules is used as an example. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device is divided into different functional modules to complete all or part of the functions described above. The specific working process of the system, device and unit described above can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.

[0345] Fig. 9 1 is a schematic diagram of the structure of a channel state information processing device provided by an embodiment of the present disclosure. The channel state information processing device can execute the information processing method provided by the above method embodiment. Fig. 9 As shown, the channel state information processing device includes: a communication unit 901 and a processing unit 902.

[0346] Among them, the communication unit 901 is used to send capability parameters to the second node; the capability parameters include at least one of the following: the maximum number L of reference signal resources, the maximum number R of time periods capable of determining channel state information, and L and R are both positive integers.

[0347] The communication unit 901 is further configured to receive configuration information determined by the second node based on the capability parameter.

[0348] The processing unit 902 is used to instruct the communication unit 901 to receive a reference signal and report channel state information based on the configuration information.

[0349] In one possible implementation, the configuration information is used to indicate at least one of the following: K reference signal resources measured by the first node, and N time periods for the first node to report channel state information; K is a positive integer less than or equal to L, and N is a positive integer less than or equal to R.

[0350] In a possible implementation, the capability parameter also includes first indication information, second indication information or third indication information; wherein the first indication information is used to indicate whether the first node has the ability to report channel state information when part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals; the second indication information is used to indicate that when part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, the first node has the ability to report channel state information; the third indication information is used to indicate that when part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, the first node does not have the ability to report channel state information.

[0351] In a possible implementation, the capability parameter also includes at least one of the following: the minimum value of K; the possible value of K; the maximum value of M; the possible value of M; the relative relationship between K and M; the ratio of M to K; the maximum value of the ratio; the possible value of the ratio; the positional relationship of M reference signal resources among the K reference signal resources; wherein M is the number of reference signal resources occupied by other signals among the K reference signal resources, and M is a positive integer; the positional relationship includes at least one of a time sequence position, a frequency domain sequence position, a spatial sequence position, and a configuration sequence position.

[0352] In one possible implementation, the capability parameter also includes at least one of the following: the possible values ​​of P; the maximum value of P; the position of the P time periods in the N time periods; wherein the P time periods are the time periods in which the first node reports channel state information when part of the reference signal resources indicated by the configuration information are occupied by other signals.

[0353] In one possible implementation, the configuration information is also used to indicate any one of the following: when part of the reference signal resources indicated by the configuration information are occupied by other signals, the first node continues to report channel state information related to the configuration information; when part of the reference signal resources indicated by the configuration information are occupied by other signals, the first node no longer reports channel state information related to the configuration information.

[0354] In a possible implementation, the communication unit 901 is specifically configured to: corresponding to the fact that part of the reference signal resources in the reference signal resources indicated by the configuration information are occupied by other signals, report channel state information for Q time periods, where Q is a positive integer less than or equal to N.

[0355] In a possible implementation manner, the value of Q is determined according to the value of M, where M is the number of reference signal resources occupied by other signals among the K reference signal resources, and M is a positive integer.

[0356] In a possible implementation manner, the value of Q is specifically determined according to K and M; or, the value of Q is specifically determined according to M and N; or, the value of Q is specifically determined according to M, K, and N.

[0357] In a possible implementation manner, the positions of the Q time periods are determined according to the position of the first reference signal resource among the M reference signal resources.

[0358] In one possible implementation, the processing unit 902 is specifically configured to instruct the communication unit 901 to receive a retransmitted reference signal and continue to report the channel state information associated with the configuration information, corresponding to the jth reference signal resource among the reference signal resources indicated by the configuration information being occupied by other signals.

[0359] In a possible implementation manner, the transmission resource occupied by the retransmitted reference signal is located in a time slot adjacent to the j-th reference signal resource.
