Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a measurement method, apparatus, node, and storage medium. Background Technology

[0002] Unlicensed spectrum is shared spectrum, and nodes must compete for channel access rights to use the spectrum. When there are many nodes, it's possible for a node to fail to secure a channel, leading to uncertainty in data transmission on the unlicensed spectrum, or a node may delay securing a channel, causing data transmission delays. Furthermore, unlicensed spectrum contains the problem of hidden nodes, such as… Figure 1 As shown, nodes 1 and 2 are affected by node 4, but node 3, which is farther away, is not affected by node 4, and node 3 cannot perceive the existence of node 4. Therefore, node 4 is a hidden node of nodes 1 and 2.

[0003] To ensure that certain services meet latency requirements, it is necessary to detect interference promptly. Two common methods for measuring channel interference are: One method is to measure the interference intensity. At each measurement moment, the received signal strength is measured. Then, over a certain period (determined by the reporting period), the received signal strength at all measurement moments is averaged to obtain the average received channel strength (e.g., received signal strength indicator). The other method is to measure the frequency and intensity of the interference. At each measurement moment, the received signal strength is measured. If the received signal strength at certain measurement moments within a certain period exceeds a certain threshold, these measurement moments are counted as a percentage of all measurement moments (e.g., channel occupancy rate). The measurement moments can be configured as periodic moments (e.g., Orthogonal Frequency Division Multiplexing (OFDM) symbols, subframes).

[0004] However, both of these methods measure the magnitude and frequency of interference probabilistically. If the configured reporting period is long, then during the measurement period, when there are some moments with strong interference, the strong interference signals will be averaged out due to the large number of measurement moments, so the interference cannot be seen from the measurement results. If the configured reporting period is short, the measurement reports are reported more frequently, and both of these measurement results are sent to the node through the Radio Resource Control (RRC) message of the measurement report, so the node cannot detect the existence of interference in time.

[0059] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0060] Furthermore, in the embodiments of this application, terms such as "optionally" or "exemplarily" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "optionally" or "exemplarily" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "optionally" or "exemplarily" is intended to present the relevant concepts in a specific manner.

[0061] To facilitate understanding of the solutions in the embodiments of this application, illustrative descriptions of some concepts related to this application are provided for reference. As shown below:

[0062] Unlicensed spectrum: Unlicensed spectrum is used in cellular network topology. It can be used as supplementary spectrum to licensed spectrum, for secondary nodes (SNs) in dual-linkage networks or for auxiliary cells in carrier aggregation, or it can be used independently for the spectrum of a single (standalone) cell. For example... Figure 2 As shown, this is the network-side architecture for 4G / 5G networking using unlicensed spectrum. Nodes (e.g., base stations) provide wireless services using unlicensed spectrum and connect to core network equipment via the NG / SI interface. Nodes are connected to each other via the Xn / X2 interface.

[0063] The Listen Before Talk (LBT) mechanism was developed by the 3rd Generation Partnership Project (3GPP) and the European Telecommunications Standards Institute (ETSI). Before sending data, the sender needs to listen for channel availability. If the channel is idle, the sender uses it to send data; otherwise, it continues listening until the channel becomes available. For example, if two nodes share a 100MHz bandwidth, and each node needs to send data, they must compete for the allocated bandwidth. If both nodes simultaneously intend to send data within the same bandwidth, they must compete for the bandwidth; only the node that wins the competition can send data.

[0064] Based on the explanation of the above concepts, Figure 3 A flowchart of a measurement method provided in an embodiment of this application is shown below. Figure 3 As shown, the method may include:

[0065] S301, The first communication node obtains the measurement information configured by the second communication node.

[0066] In this embodiment, the first communication node and the second communication node can be two different types of communication nodes. For example, the first communication node can be understood as a terminal, and the second communication node can be understood as a base station. Therefore, this step can be understood as the terminal acquiring the measurement information configured by the base station.

[0067] S302. The first communication node performs measurements based on the measurement information and obtains the measurement results.

[0068] The second communication node can configure measurements for the first communication node via RRC messages (e.g., RRC reconfiguration messages). For example, the second communication node can configure measurement information and measurement trigger conditions. After receiving the message, the first communication node determines that the second communication node has configured measurement trigger conditions and can then perform conditional measurement; if the second communication node has not configured measurement trigger conditions, it can perform measurements based on the measurement information.

[0069] S303. If the measurement results meet the reporting conditions, the first communication node reports a channel status indication carrying the measurement results.

[0070] After the first communication node performs the measurement based on the measurement information, it can obtain the measurement result. If it confirms that the measurement result meets the reporting conditions, it reports the channel status indication to the second communication node, which carries the measurement result.

[0071] In this way, the second communication node can confirm the actual state of the current channel based on the measurement results reported by the first communication node. If the second communication node determines that the first communication node has been interfered with, it can schedule the first communication node to other frequency domains, thereby ensuring the normal transmission of services with high latency requirements (such as Ultra Reliable Low Latency Communications, URLLC) on the first communication node.

[0072] In this embodiment of the application, the measurement information configured by the second communication node may include an indication of whether the first communication node is enabled to perform measurement, or, if the first communication node is enabled to perform measurement, a configured measurement trigger condition, or, the measurement window duration and the interval granularity of the measurement window, or, pre-configured resources, or, the second communication node may configure indication information to explicitly indicate whether the first communication node needs to perform measurement.

[0073] For example, the second communication node can carry a cell in the RRC message that enables the first communication node to perform a measurement. This cell can be a 1-bit (e.g., 1 enables measurement) or an enumeration value (e.g., the enumeration value option enables measurement).

[0074] The aforementioned measurement window may include a preset duration or multiple measurement times, and the pre-configured resources may be the time and frequency resources configured for the second communication node.

[0075] For example, the second communication node can indicate whether the first communication node is enabled to perform measurements by configuring the presence of certain measurement configurations (e.g., one or more measurement configurations). For instance, the service quality parameters of the carried service can be used to indicate whether the first communication node is enabled to perform measurements. For example, if the latency requirement of a service mapped to a certain Resource Bearer Data (DRB) is less than a threshold value, the first communication node can perform a conditional measurement. The second communication node configures a DRB and maps it to URLLC services via an RRC message. Upon receiving this message, the first communication node, if it determines that the latency requirement of the service mapped to the DRB is less than a threshold value, then performs a conditional measurement.

[0076] The first communication node determines whether to perform a conditional measurement by indicating the transmission delay of the service being carried. For example, if the transmission delay requirement of a service mapped to a certain DRB is less than a certain threshold, the first communication node will perform a conditional measurement. The second communication node configures a DRB that maps to a URLLC service via an RRC message. When the first communication node receives this message, if it determines that the air interface transmission delay requirement of the URLLC service mapped to the DRB is less than the threshold, it will also perform a conditional measurement.

[0077] The ability to perform measurements by checking whether there is data to be transmitted on a logical channel or whether the corresponding uplink scheduling request (SR) for that logical channel has been triggered indicates whether the first communication node should be enabled. For example, if a second communication node maps URLLC services to a logical channel and configures SR resources for that logical channel, when the first communication node determines that there is data to be transmitted on that logical channel or that the corresponding SR has been triggered, then the first communication node will perform conditional measurements.

[0078] Whether the first communication node is enabled to perform measurements is determined by whether the first type of configuration grant (type1 configured grant) is configured, or whether the second type of configuration grant (type2 configured grant) or semi-persistent scheduling (SPS) is activated. If the second communication node configures the first communication node with a type1 configured grant, or activates a type2 configured grant or SPS, then the first communication node performs a conditional measurement determination.

[0079] Optionally, the second communication node can also be configured with measurement trigger conditions. If the first communication node determines that the measurement trigger conditions have been met when the first communication node is enabled, it can perform the measurement according to the configuration; otherwise, the first communication node will not perform the measurement.

[0080] For example, the measurement triggering conditions configured for the second communication node may include the received signal strength being greater than a signal strength threshold, or the received signal strength being greater than a signal strength threshold for several consecutive measurement times, or the LBT failure rate being greater than a first threshold within a preset time period, or the occupancy rate of the measurement channel being greater than a second threshold within a preset time period, or the retransmission probability of the data packet being greater than a third threshold.

[0081] When the first communication node confirms that the measurement triggering condition is met, the first communication node can perform measurements for the next period of time and calculate the channel state indication or measurement result based on the measurement values ​​during this period.

[0082] For example, the second communication node configuring the measurement configuration of the first communication node via RRC messages may include at least one of the following:

[0083] The object being measured, for example, a specific frequency point, or the bandwidth portion (BWP);

[0084] Measure bandwidth, such as a single LBT bandwidth or multiple LBT bandwidths, where the multiple LBT bandwidths can be contiguous or discontinuous. For example, if configured as multiple LBT bandwidths, the starting frequency domain position and frequency domain length can be configured, or a list can be configured where each item includes the starting frequency domain position and frequency domain length.

[0085] Measurement triggering conditions include, for example, the received signal strength being higher than a signal strength threshold, or the received signal strength being higher than a signal strength threshold for several consecutive measurement times, or the LBT failure rate being greater than a first threshold within a certain period of time, or the occupancy rate of the measured channel exceeding a second threshold within a certain period of time, or the Hybrid Auto Repeat Request (HARQ) retransmission probability of data packets reaching a third threshold. Each of the above thresholds can be configured by the second communication node.

[0086] Measurement time or measurement window, for example, the measurement time can be determined by the period and the duration of each period, or the measurement time can be a continuous period of time.

[0087] Measured quantities, such as measuring interference intensity or interference frequency.

[0088] When the first communication node is measuring, if it determines that the configured measurement triggering condition is met at a certain moment, the first communication node will measure the configured measurement object (one or more frequency domains) according to the configured measurement time, and calculate the channel state indication or measurement result of the measured quantity (one or more frequency domains) based on the measurement value within the measurement time.

[0089] The above process is described below with a specific example. For instance, the second communication node configures the measurement settings via an RRC reconfiguration message, including: measuring a specific frequency point with a measurement bandwidth of 20MHz, a signal strength threshold for the received signal strength, measuring over several consecutive time slots, and measuring the received signal strength indication and channel occupancy rate. When the first communication node performs the received signal strength indication measurement, if it determines that the received signal strength at a certain moment is higher than the signal strength threshold, then the first communication node performs the measurement according to the configured measurement times and obtains the received signal strength indication and channel occupancy rate based on the received signal strength indication measurements at all measurement times within the specified time period.

[0090] Alternatively, the second communication node configures the measurement settings via RRC reconfiguration messages, including: measuring a specific frequency point with a bandwidth of 20MHz, determining the transmission delay threshold of a specific DRB, with the measurement time determined by a certain period and duration, and the measured quantities being the received signal strength indication (RSI) and channel occupancy rate. When the first communication node performs RSI measurement, if it determines that the transmission delay of a specific DRB is higher than the DRB's transmission delay threshold, the first communication node performs the measurement according to the configured measurement duration and obtains the RSI and channel occupancy rate based on the RSI measurement values ​​at all measurement times within the measurement duration.

[0091] Alternatively, the second communication node configures the measurement settings via RRC reconfiguration messages, including: measuring a specific frequency point, a continuous 100MHz measurement bandwidth, a trigger threshold for received signal strength, a measurement duration of a certain duration, and the measured quantities being received signal strength indication and channel occupancy. When the first communication node performs received signal strength indication measurement, if it determines that the received signal strength of a certain 20MHz band at a certain moment is higher than the received signal strength threshold, it will measure the 100MHz band according to the configured measurement duration. For example, for each 20MHz band, based on the received signal strength indication measurements at all measurement moments within the measurement duration, five 20MHz received signal strength indications and channel occupancy rates are obtained.

[0092] In the example above, the first communication node can perform measurements on one or more frequency domains based on the measurement information at the measurement time.

[0093] When the measurement information is a measurement window, the first communication node can measure all measurement moments within the measurement window, obtain the measurement results for all measurement moments, and calculate the measurement values ​​for all measurement moments to obtain the final measurement result. Then, the measurement window can slide to the next time period, which can be determined according to the interval granularity of the measurement window. The interval granularity of the measurement window can be a period of time or multiple measurement moments. At this time, the measurement window is still a fixed duration, and the first communication node repeats the same method to obtain the measurement values ​​for all measurement moments within the measurement window and calculate the final measurement result.

[0094] Alternatively, the first communication node performs the measurement at the measurement moment, and starting from that moment, obtains the measurement values ​​for all measurement moments within the measurement window of length, and calculates the measurement result. The measurement result generated at this measurement moment is spaced apart from the measurement result generated at the previous measurement moment by a certain period of time, which is determined by the interval granularity of the measurement window.

[0095] Alternatively, the first communication node obtains the measurement values ​​at all measurement times within the measurement window, calculates a temporary result, and then weights this temporary result with the measurement result obtained in the previous measurement window to obtain the final measurement result. That is, the first communication node weights the current measurement result with the previous measurement result to obtain the final measurement result. For example, the first communication node obtains result 1 in measurement window 1 and temporary result 2 in measurement window 2. The final measurement result is obtained using a weighting method of a*result 1 + b*result 2, where a and b are the weights.

[0096] Similarly, the above process will be further described in detail with a specific example. For instance, the second communication node is configured with a measurement period of 10ms, a start time of slot 0, a measurement duration of 11 symbols, a measurement window of 50ms, and an interval granularity of 10ms. After obtaining the measurement configuration, the first communication node obtains the measurement times as slot 0 symbol 0 to symbol 10, slot 10 symbol 0 to symbol 10, slot 20 symbol 0 to symbol 10, slot 30 symbol 0 to symbol 10, slot 40 symbol 0 to symbol 10, slot 50 symbol 0 to symbol 10, and so on. The first communication node obtains the measurement values ​​for all measurement times (e.g., slot 0 symbol 0 to slot 40 symbol 10), such as the received signal strength at each measurement time, and averages them to obtain the received signal strength; or, if the received signal strength at a measurement time is higher than a signal strength threshold, the channel occupancy rate is obtained based on the percentage of these measurement times out of all measurement times. The subsequent measurement times are slot10 symbol 0 to symbol 10, slot20 symbol 0 to symbol 10, slot30 symbol 0 to symbol 10, slot40 symbol 0 to symbol 10, slot50 symbol 0 to symbol 10, ... The first communication node obtains the measurement values ​​for all measurement times (e.g., slot10 symbol 0 to slot50 symbol 10), and then obtains the received signal strength or channel occupancy rate, and so on.

[0097] When the measurement information is a pre-configured resource, the first communication node performs measurements on one or more frequency domains at the transmission time of the pre-configured resource, that is, the measurement time is the transmission time of the pre-configured resource.

[0098] For example, the second communication node configures pre-configured resources (configured grant or SPS), which include transmission time (determined by period, start time, etc.), frequency domain location, etc. The second communication node configures the first communication node to measure the pre-configured resources via RRC messages, Media Access Control Element (MAC CE), or DCI. The measurement object is the frequency domain location of the pre-configured resource (e.g., start or center position) or the index of the pre-configured resource; the measurement bandwidth is the bandwidth occupied by the pre-configured resource; the measurement time is the transmission time of the pre-configured resource; and the measured quantity can be received signal strength, channel occupancy, LBT failure probability, etc. The RRC message, MAC CE, or DCI can carry the index of the pre-configured resource. After obtaining the configuration information, the first communication node uses the frequency domain where the pre-configured resource is located as the measurement object, the occupied bandwidth as the measurement bandwidth, and performs the measurement at the pre-configured transmission time to obtain the measurement result.

[0099] The process described above is illustrated below with a specific example. Assume the second communication node configures a pre-configured resource with a period of 10ms, starting at slot 0, with 0 symbols, a duration of 5 symbols, and a frequency domain location of the starting position M and the number of occupied PRBs N, with index X. The second communication node configures the measurement object as the pre-configured resource at index X, and the measurement quantity as the LBT failure probability. After obtaining the configured measurement information, the first communication node determines the measurement object as the frequency point corresponding to (M+N) / 2, the measurement bandwidth as the bandwidth corresponding to N, and the measurement times as slot 0 symbol 0~symbol 4, slot 10 symbol 0~symbol 4, slot 20 symbol 0~symbol 4, ..., and the first communication node calculates the LBT failure probability at these measurement times.

[0100] Since the communication quality of a channel can be reflected by measurement results, if the first communication node determines that the channel quality is poor or there is strong interference based on the measurement results, it can promptly report the measurement results to the second communication node.

[0101] In this embodiment of the application, the second communication node can configure the conditions for the first communication node to report a channel state indication carrying measurement results via RRC messages. Exemplarily, the conditions may include at least one of the following:

[0102] Trigger time, for example, the time required to meet the reporting trigger conditions;

[0103] Report trigger conditions, such as measurement results exceeding a certain threshold.

[0104] Reporting methods include, for example, Physical Uplink Control Channel (PUCCH), MAC CE, RRC messages, Physical Random Access Channel (PRACH), and Sounding Reference Signal (SRS).

[0105] When the first communication node performs measurements, if it determines that a certain measurement result (one or more LBT bandwidths) consistently meets the reporting triggering conditions within the triggering time, it triggers the reporting of the channel status indicator according to the reporting method. The channel status indicator may carry the measurement result that meets the reporting conditions (or multiple measurement results corresponding to multiple LBT bandwidths), and / or the measurement object corresponding to the measurement result.

[0106] For example, the second communication node configures the measurement settings via RRC reconfiguration messages, including measuring a specific frequency point, a measurement bandwidth of 20MHz, the measurement time period and duration of each period, the signal strength threshold for the received signal strength indication, the measured quantity being the received signal strength indication, the duration of the trigger time, and the reporting trigger condition being that the received signal strength indication at all measurement moments within the trigger time is greater than the signal strength threshold. The reporting method is PUCCH, and corresponding PUCCH resources are configured. When the first communication node performs measurements, if it determines that the received signal strength at a certain moment is higher than the signal strength threshold, it measures the received signal strength indication according to the configured measurement time. If the received signal strength indication at all measurement moments within the trigger time is higher than the signal strength threshold, the first communication node transmits a signal on the configured PUCCH resources.

[0107] The second communication node configures the measurement settings via RRC reconfiguration messages. These settings include measuring a specific frequency point with a bandwidth of 100MHz, the measurement time period and duration of each period, the signal strength threshold for the received signal strength indication, the measured quantity being the received signal strength indication, the duration of the trigger time, and the reporting trigger condition: that the received signal strength indication at all measurement moments within a certain 20MHz range during the trigger time is greater than the signal strength threshold. The reporting method is PUCCH, and corresponding PUCCH resources are configured. When the first communication node performs measurements, if it determines that the received signal strength at a certain moment within a certain 20MHz range is greater than the received signal strength threshold, the first communication node will measure the received signal strength indication according to the configured measurement time. If the received signal strength indication at all measurement moments within a certain 20MHz range during the trigger time is greater than the signal strength threshold, the first communication node will send a 100MHz interference indication to the second communication node via the configured PUCCH resources.

[0108] In one example, the channel state indication reported by the first communication node can be achieved by the first communication node reporting through a first transmission resource, wherein the first transmission resource includes any of the following transmission resources: MAC CE, PUCCH, SRS, PRACH, Uplink Control Information (UCI). Furthermore, the reported channel state indication can also be determined by measurements such as Reference Signal Receiving Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indication (RSSI), and Channel Occupancy (CO).

[0109] For example, the first communication node using MAC CE can report channel information and channel quality, or only report channel information. Channel quality can be the quality of the received signal, the magnitude of interference, the interference value, etc., and channel information can be frequency point, frequency point index, etc.

[0110] For example, channel quality can be represented by measurements such as interference intensity and interference frequency, and reported to the second communication node via MAC CE. If the measurement result has a large range, it can be quantized. Thus, when the measurement result falls within a certain range, the reported result is a quantized value. For example, when 80 < channel occupancy < 100, the quantized channel occupancy is high, which can be represented as 11.

[0111] For channel information, this can include the identifier of the measurement object, frequency domain index, etc. For example, a frequency domain identifier can be used. If channel information and channel quality are reported, then the relationship between the channel information and its channel quality needs to be considered. When reporting, not only the channel quality needs to be carried, but also the identifier of the frequency domain to which the measurement result belongs. For example, MAC CE can include an identifier bit, a frequency domain identifier, and the measurement result. The identifier bit is used to identify what type of measurement result it is, the frequency domain identifier is used to identify which frequency band it is, and the measurement result can be a quantized value or an actual value. The MAC CE format can be... Figure 4 The format of the reported measurement results. If multiple frequency domain measurement results need to be reported, the MAC CE needs to carry multiple measurement results. The MAC CE can arrange the multiple measurement results in frequency domain order, for example, from low to high frequency domain. For example, if the measurement object configured for the second communication node is a certain frequency point with a measurement bandwidth of 100MHz, and the first communication node can obtain a measurement result for each 20MHz, then the first communication node only needs to report one frequency domain identifier and arrange the measurement results in order from low to high frequency domain. The format of this reported MAC CE can be... Figure 5 The form of representation.

[0112] If only channel information is reported, the quality of the channel can be implicitly represented, for example, by the order in which the channel quality is indicated. If the channel information can be a frequency domain identifier, then the MAC CE needs to carry multiple frequency domain identifiers, such as... Figure 6 As shown, MAC CE can arrange the measurement results of multiple frequency domains in ascending or descending order of frequency domain identifiers. For example, if the second communication node is configured to measure a certain frequency point with a measurement bandwidth of 100MHz, and the second communication node can obtain a measurement result for each 20MHz, then the second communication node can arrange the frequency domain identifiers in ascending order of frequency domain identifiers.

[0113] The first communication node can also report channel quality using the PUCCH method. Channel quality can be the quality of the received signal or interference indication. Interference indication includes the level of interference and the interference value.

[0114] The second communication node can configure PUCCH resources for reporting channel quality. If the time-frequency resources configured for the PUCCH resources are related to the frequency domain identifier (i.e., different PUCCH time-frequency resources are bound to different frequency domains), then if the first communication node reports the channel quality of a certain frequency domain, it only needs to report the channel quality at the corresponding PUCCH resource location. Conversely, if the time-frequency resources configured for the PUCCH resources are not related to the frequency domain identifier, then when the first communication node reports the channel quality of a certain frequency domain, it needs to report both the channel quality and the frequency domain identifier at the configured PUCCH resource location.

[0115] In addition, when the first communication node reports channel quality, it can also report specific channel quality values. If it's an interference indication, the measurement result can be a numerical value or the reported level of interference. When reporting channel quality, the first communication node can use measurement results such as interference intensity or interference frequency to represent the channel quality and report them to the second communication node via PUCCH. If the measurement result has a large range, it can be quantized. If the measurement result is within a certain range, the reported measurement result is quantized into a value representing that range. When reporting, if it's necessary to include the identifier of the frequency domain to which the measurement result belongs (e.g., the identifier of the measurement object, frequency domain index), the bits of the PUCCH sequence include an identifier bit, frequency domain identifier 1, measurement result 1, frequency domain identifier 2, measurement result 2, and so on. The identifier bit identifies the type of measurement result, the frequency domain identifier identifies the frequency band, and the measurement result can be a quantized value or an actual value.

[0116] If multiple frequency domain measurement results need to be reported, then the PUCCH needs to carry multiple measurement results. If the second communication node is configured to measure multiple frequency domains, the PUCCH can arrange the multiple frequency domain measurement results sequentially from low to high frequency domain. The bits of the PUCCH sequence include an identifier bit, a frequency domain identifier, measurement result 1, measurement result 2, measurement result 3, and so on.

[0117] When reporting channel quality (such as interference) levels to the second communication node via PUCCH, if a frequency domain identifier is not required, then when the first communication node reports interference in a certain frequency domain, it needs to send a one-bit PUCCH (e.g., SR) at the corresponding PUCCH resource location. For example, an all-1-bit sequence indicates high or low interference. If a frequency domain identifier is required, then when the first communication node reports interference in a certain frequency domain, the bits of the PUCCH sequence can include an identifier bit, the frequency domain identifier, and the measurement result.

[0118] When reporting channel quality (such as interference) across multiple frequency domains to the second communication node via PUCCH, the measurement results can be arranged sequentially from low to high frequency domain. This can be represented using a bitmap, where each bit is associated with a frequency domain. For example, with four frequency domains, reporting 1010 via PUCCH indicates high interference in frequency domains 0 and 2, and low interference in frequency domains 1 and 3. If a frequency domain identifier is required, the bits in the PUCCH sequence when the first communication node reports interference in a specific frequency domain can include an identifier bit, a frequency domain identifier, and a measurement result bitmap.

[0119] When the first communication node reports channel quality using SRS, the time-frequency resources configured for SRS can be related to the frequency domain identifier. That is, the time-frequency resources of different SRSs are bound to different frequency domains. If the first communication node reports the channel quality of a certain frequency domain, it only needs to report the interference situation at the corresponding SRS resource location. If the first communication node reports the channel quality (such as interference) using SRS, and reports poor channel quality or high interference in a certain frequency domain, then the first communication node needs to send an SRS sequence at the corresponding SRS resource location.

[0120] When the first communication node reports channel quality using PRACH, the time-frequency resources configured for that PRACH by the second communication node, and / or the preamble, can be related to the frequency domain identifier. That is, the time-frequency resources for different PRACHs, and / or the preamble, are bound to different frequency domains. Therefore, if the first communication node reports channel quality for a certain frequency domain, it only needs to send the corresponding preamble at the corresponding PRACH resource location. Similarly, the first communication node can also use PRACH to report the level of interference. For example, when the first communication node reports high interference in a certain frequency domain, it needs to send a preamble sequence at the corresponding PRACH resource location.

[0121] When the second communication node schedules the PUSCH of the first communication node, the first communication node can carry a UCI on the PUSCH. The UCI carries channel quality (such as interference conditions) and channel information, which can be a frequency point, frequency index, etc. The reported channel quality can be obtained by measuring interference strength, measuring interference frequency, etc. If both channel information and channel quality are reported, the relationship between the channel information and its channel quality needs to be specified. That is, the UCI needs to carry not only channel quality but also an identifier of the frequency domain to which the measurement result belongs. For example, the UCI can include an identifier bit, frequency domain identifier 1, measurement result 1, frequency domain identifier 2, measurement result 2, etc., where the identifier bit identifies the type of measurement result, the frequency domain identifier identifies the frequency band, and the measurement result can be a quantized value or an actual value.

[0122] If multiple frequency domain measurement results need to be reported, then the UCI needs to carry multiple measurement results. If the measurement object configured for the second communication node is multiple frequency domains, then the UCI can arrange the multiple frequency domain measurement results in order from low frequency domain to high frequency domain. Accordingly, the bits of the PUCCH sequence can include an identifier bit, a frequency domain identifier, measurement result 1, measurement result 2, measurement result 3, and so on.

[0123] When reporting channel quality (such as interference) across multiple frequency domains to the second communication node via UCI, a bitmap can be used. The measurement results for each frequency domain are arranged sequentially from low to high frequency, with each bit associated with a frequency domain. For example, with four frequency domains, a UCI report of 1010 indicates high interference in frequency domains 0 and 2, and low interference in frequency domains 1 and 3. If a frequency domain identifier is required, the bits in the UCI sequence when the first communication node reports interference in a specific frequency domain can include an identifier bit, a frequency domain identifier, and the measurement result bitmap.

[0124] Figure 7 A flowchart of a measurement method provided in an embodiment of this application is shown below. Figure 7 As shown, the method may include:

[0125] S701, The first communication node obtains the enable information configured by the second communication node.

[0126] In this embodiment, the enable information configured by the second communication node is used to indicate whether to enable the first communication node to activate the Packet Data Convergence Protocol duplication (PDCP duplication) function, and / or whether to enable the first communication node to deactivate the PDCP duplication function. That is, the second communication node can jointly configure whether the first communication node has the function of autonomously activating or deactivating PDCP duplication. For example, two bits can be configured in the RRC signaling: 00 represents that the first communication node or logical channel does not have the function of autonomously activating and deactivating PDCP duplication; 01 represents that the first communication node or logical channel has the function of autonomously activating but not deactivating PDCP duplication; 10 represents that the first communication node or logical channel has the function of autonomously deactivating but not activating PDCP duplication; and 11 represents that the first communication node or logical channel has the function of autonomously activating and deactivating PDCP duplication.

[0127] S702, The first communication node operates the PDCP duplication function according to the enable information.

[0128] For example, the above operation method can be that when the enable information indicates that the first communication node is enabled to activate the PDCP duplication function, the first communication node can determine whether to activate the PDCP duplication function according to the first judgment condition, wherein the first judgment condition includes at least one of the following: the result of preempting the channel, the service delay, the data transmission duration, the channel state, and the first communication node's determination of whether to activate the PDCP duplication function.

[0129] For example, whether the first communication node or a certain logical channel has activated PDCP duplication can be determined in the following ways:

[0130] Method 1: The result of the first communication node preempting the channel can be expressed as the number or percentage of times the first communication node successfully preempts the channel within a certain time in a certain frequency domain (e.g., carrier, channel, BWP, etc.), or the average number or percentage of times the first communication node successfully preempts the channel in multiple frequency domains at a certain moment (e.g., transmission time interval (TTI), slot, symbol, time point, etc.). For example, if the number or percentage of times the first communication node successfully preempts the channel is lower than a threshold and the first communication node has uplink data to transmit; or, if the number or percentage of times the first communication node successfully preempts the channel is lower than a threshold and the delay requirement for the uplink data to be transmitted by the first communication node is less than a delay threshold; or, if the number or percentage of times the first communication node successfully preempts the channel is lower than a threshold and the delay of the data to be transmitted by the first communication node is greater than a delay threshold, then the first communication node activates PDCP duplication and transmits a duplicated PDCP SDU in other frequency domains.

[0131] It should be noted that the above method can also be applied to logical channels. That is, the first communication node counts the number of times a logical channel is successfully preempted or the data transmission delay, and then determines whether to activate the PDCP duplication of the logical channel.

[0132] Method 2: The result of the first communication node preempting the channel can be represented as the number of consecutive LBT failures occurring within a certain time period in a certain frequency domain (e.g., carrier, channel, BWP, etc.). For example, if the number of consecutive LBT failures exceeds a threshold and the first communication node has uplink data to be transmitted, or if the number of consecutive LBT failures exceeds a threshold and the delay requirement for the uplink data to be transmitted is less than a delay threshold, or if the number of consecutive LBT failures exceeds a threshold and the data transmission delay is greater than a delay threshold, then the first communication node activates PDCP duplication and transmits a duplicated PDCP SDU in other frequency domains.

[0133] Similarly, this method can be applied to the first communication node to count the number of consecutive LBT failures or the data transmission delay of a certain logical channel, and then determine whether to activate the PDCP duplication of that logical channel.

[0134] Method 3: The first communication node can also determine that the data packet retransmission rate of a certain service or logical channel is higher than a certain threshold value, and satisfies either Method 1 or Method 2.

[0135] For example, if a URLLC service is mapped to a logical channel, and its data packet HARQ retransmission rate is higher than the corresponding threshold, and the probability of the first communication node preempting the channel is very low, then the first communication node activates PDCP duplication and sends the replicated PDCP SDU in other frequency domains; otherwise, it deactivates PDCP duplication.

[0136] The aforementioned time period and various threshold values ​​can all be configured by the second communication node.

[0137] Furthermore, the second communication node can also pre-configure candidate carriers for the first communication node to support PDCP duplication, such as carriers, channels, BWPs, etc. The first communication node can select an active candidate frequency domain from the candidate carriers according to a first selection condition for transmitting PDCP duplication data packets. The first selection condition is the result or trigger level of the first communication node preempting the channel.

[0138] For example, the first communication node selects the active frequency domain (e.g., carrier, channel, BWP, etc.) based on the channel preemption results. The first communication node sorts the frequency domains based on the preemption results or measurement results for each frequency domain, selecting those with higher channel preemption probabilities. For instance, it can sort by the number of times the first communication node successfully preempted the channel, or the percentage of successful preemption, from largest to smallest, preferentially selecting carriers with a high number of successful preemption attempts or a high percentage of successful preemption. Alternatively, it can sort by received signal strength indication (RSI) or channel occupancy rate (COR) from smallest to largest, preferentially selecting carriers with a low RSI or low COR.

[0139] The first communication node selects to activate several frequency domains (e.g., carrier, channel, BWP, etc.) based on the trigger level. If several activation conditions are set, the corresponding number of frequency domains are activated based on the conditions met. For example, if the number of times the first communication node successfully preempts a channel, or the percentage of times the first communication node successfully preempts a channel, is below a first threshold and the uplink latency requirement for the data to be transmitted on the first communication node is less than a second threshold, then the first communication node activates PDCP duplication in one frequency domain. The frequency domain is selected according to the above method based on the channel preemption results. If the number of times the first communication node successfully preempts a channel, or the percentage of times the first communication node successfully preempts a channel, is below a third threshold and the uplink latency requirement for the data to be transmitted on the first communication node is less than a fourth threshold, then the first communication node activates PDCP duplication in two frequency domains. The frequency domain is selected according to the above method based on the channel preemption results.

[0140] The first threshold, second threshold, third threshold, and fourth threshold mentioned above can be configured by the second communication node.

[0141] When the enable information instructs the first communication node to activate the PDCP duplication function, the first communication node determines whether to activate the PDCP duplication function based on the second judgment condition, wherein the second judgment condition includes at least one of the following: the result of preempting the channel, the service delay, the data transmission duration, the channel state, and the first communication node's determination of whether to activate the PDCP duplication function.

[0142] For example, whether the first communication node or a certain logical channel should deactivate PDCP duplication can be determined in the following ways:

[0143] Method 1: The result of the first communication node preempting the channel can be expressed as the number or percentage of times the first communication node successfully preempts the channel within a certain time in a certain frequency domain (e.g., carrier, channel, BWP, etc.); or, the average number or percentage of times the first communication node successfully preempts the channel across multiple frequency domains at a certain moment (e.g., TTI, slot, symbol, time point, etc.). If the number of times the first communication node successfully preempts the channel is greater than a threshold, or if the number of times the first communication node successfully preempts the channel is greater than the threshold and the data transmission delay is less than the time domain threshold, then the first communication node deactivates PDCP duplication.

[0144] The above method can also be applied to logical channels. The first communication node counts the number of times a logical channel is successfully preempted or the data transmission delay, and determines whether to activate the PDCP duplication of that logical channel.

[0145] Method 2: The first communication node's channel preemption can be represented by the number of consecutive LBT failures occurring within a certain time period in a specific frequency domain (e.g., carrier, channel, BWP, etc.). If the number of consecutive LBT failures is less than a threshold, or if the number of consecutive LBT failures is less than a threshold and the data delay is less than a delay threshold, then the first communication node deactivates PDCP duplication.

[0146] Similarly, the above method can also involve the first communication node counting the number of consecutive LBT failures or the data transmission delay of a certain logical channel, and determining whether to activate the PDCP duplication of that logical channel.

[0147] Method 3: The data packet retransmission rate of a certain service or logical channel is lower than a certain threshold, and it meets the requirements of Method 1 or Method 2 above.

[0148] For example, if a URLLC service is mapped to a logical channel, and its data packet HARQ retransmission rate is less than the threshold, and the probability of the first communication node preempting the channel is very high, then PDCP duplication should be deactivated.

[0149] The threshold value and time period in the above method can be configured by the second communication node.

[0150] In the frequency domains configured by the second communication node that are already activated for transmitting PDCP duplication data packets, the first communication node can select which frequency domains will no longer transmit PDCP duplication data packets.

[0151] For example, the first communication node sorts the frequency domains based on channel preemption status or measurement results in each frequency domain, and selects the frequency domains with lower channel preemption probabilities for activation. For instance, it sorts the frequency domains by the number of times the first communication node successfully preempts the channel, or by the percentage of times the first communication node successfully preempts the channel, from largest to smallest, preferably activating the frequency domains with fewer successful preemption attempts or a smaller percentage of successful preemption; or, it sorts the frequency domains by received signal strength indication, or channel occupancy rate, from smallest to largest, preferably activating the frequency domains with larger received signal strength indication or higher channel occupancy rates.

[0152] The first communication node selects several frequency domains (e.g., carrier, channel, BWP, etc.) to activate based on the trigger level. Several deactivation conditions are set, and the first communication node selects to activate the corresponding number of frequency domains based on the conditions met. For example, if the number of times the first communication node successfully preempts a channel or the percentage of times it successfully preempts a channel is higher than a first threshold and the data transmission delay is lower than a second threshold, then the first communication node activates PDCP duplication in one frequency domain, selected according to the method described above. If the number of times the first communication node successfully preempts a channel or the percentage of times it successfully preempts a channel is higher than a third threshold and the data transmission delay is lower than a fourth threshold, then the first communication node activates PDCP duplication in two frequency domains, again selected according to the method described above.

[0153] In the above manner, when the first communication node has multiple carriers, the PDCP duplication function is used to copy the PDCP Service Data Unit (SDU) into multiple SDUs, which are then transmitted on multiple carriers to obtain frequency gain, thereby increasing the reliability of data transmission.

[0154] Figure 8 This is a flowchart illustrating a measurement method provided in an embodiment of this application, as shown below. Figure 8 As shown, the method includes:

[0155] S801. When the channel state meets the first condition, the first communication node selects the frequency domain according to the channel state.

[0156] For example, in this embodiment, the first condition may be that the data packet retransmission rate is greater than a threshold value, or that the number of consecutive LBT failures in the frequency domain of the first communication node is greater than or equal to a preset number.

[0157] Among them, the data packet retransmission rate can be understood as the data packet retransmission rate of a certain service or logical channel. That is, when the data packet retransmission rate of a certain service or logical channel is higher than the threshold value, the first communication node can select the frequency domain according to the channel status.

[0158] S802, The first communication node sends an uplink signal in the selected frequency domain.

[0159] In this embodiment of the application, when the channel state meets the first condition, the first communication node selects the frequency domain according to the channel state and sends uplink signals in the selected frequency domain, which can effectively ensure the normal transmission of services with low latency.

[0160] For example, in step S801 above, one possible implementation of the first communication node selecting the frequency domain based on the channel state is that the first communication node selects the frequency domain with less interference based on the interference results of the measured frequency domain (e.g., BWP). The interference may include at least received signal strength indication, channel occupancy, etc. When a PRACH resource is configured on a certain BWP, and the received signal strength indication of that BWP is the lowest, and / or the channel occupancy is the lowest, then the first communication node selects that BWP.

[0161] In addition, to reduce the latency of the above process, the embodiments of this application also provide the following implementation methods.

[0162] For example, if the timer of the first communication node has not timed out, it confirms that the first communication node maintains uplink synchronization. If the first communication node still maintains uplink synchronization, it can send an SR or PUCCH signal on the selected frequency domain to notify the second communication node that the first communication node has selected that frequency domain. For instance, if the first communication node experiences consecutive LBT failures on the currently active BWP, without stopping the TA timer, and selects a new BWP, if the TA timer has not timed out, the first communication node considers that it still maintains uplink synchronization. Therefore, the first communication node will send an SR or PUCCH signal on the selected BWP to notify the second communication node that it has selected that BWP. The second communication node can configure SR or PUCCH resources for the first communication node on the configured BWP, which can be used to indicate that the first communication node has undergone a frequency domain selection process.

[0163] Alternatively, the first communication node initiates a two-step RACH connection to the selected frequency domain. For example, if the first communication node experiences consecutive LBT failures on the currently active BWP, the user will initiate a two-step RACH procedure on the selected BWP. When the first communication node experiences a certain number of consecutive uplink LBT failures in a certain frequency domain, the first communication node can simultaneously transmit preamble and PUSCH data on the selected frequency domain, or transmit the preamble first and then the PUSCH.

[0164] Alternatively, the first communication node transmits a PUSCH carrying a UCI in the selected frequency domain. The UCI carries an indication that a frequency domain selection process has occurred. For example, if the first communication node experiences consecutive LBT failures in the currently active BWP, it will transmit PUSCH data on the selected BWP according to the configured pre-configuration (e.g., SPS, configured grant) or resource pool (e.g., resources shared by multiple first communication nodes). The PUSCH carries a UCI, which contains an indication bit. For example, if the indication bit is 1, it indicates that a BWP selection process has occurred.

[0165] In addition, in this embodiment of the application, the first communication node can also obtain the activation information configured by the second communication node, which is used to indicate whether the first communication node is enabled to activate one or more frequency domain resource functions.

[0166] When the activation information indicates that the first communication node is enabled to activate one or more frequency domain resource functions, the first communication node determines to activate one or more frequency domain resource functions according to a third judgment condition, wherein the third judgment condition includes at least one of the following: the result of preempting the channel, the service delay, the data transmission duration, and the channel state.

[0167] For example, the third judgment condition mentioned above can be at least one of the following implementation methods:

[0168] Method 1: The result of the first communication node preempting the channel can be expressed as the number or percentage of times the first communication node successfully preempts the channel in a certain frequency domain (e.g., BWP, carrier, etc.) within a certain time period; or the average number or percentage of times the first communication node successfully preempts the channel in multiple frequency domains at a certain moment (e.g., TTI, slot, symbol, time point, etc.). If the number or percentage of times the first communication node successfully preempts the channel is lower than a threshold and the first communication node has uplink data to be transmitted, or if the number or percentage of times the first communication node successfully preempts the channel is lower than a threshold and the delay requirement of the uplink data to be transmitted on the first communication node is less than a delay threshold, then the first communication node is activated and selects another frequency domain.

[0169] Method 2: The channel preemption situation of the first communication node can be represented as the number of consecutive LBT failures occurring within a certain time in a certain frequency domain (e.g., carrier, BWP, etc.). If the number of consecutive LBT failures exceeds a threshold and the first communication node has uplink data to be transmitted, or if the number of consecutive LBT failures exceeds a threshold and the delay requirement of the uplink data to be transmitted on the first communication node is less than a delay threshold, then the first communication node is activated and selects another frequency domain.

[0170] Method 3: The packet retransmission rate of a certain service or logical channel is higher than a certain threshold, and it meets the requirements of Method 1 or Method 2 above. For example, if a URLLC service is mapped to a logical channel, its packet HARQ retransmission rate is higher than the threshold, and the probability of the first communication node preempting the channel is very low, then the first communication node will activate multiple frequency domains.

[0171] It should be noted that the time intervals and various threshold values ​​(including the delay threshold value) in the above methods can be configured by the second communication node.

[0172] Furthermore, when the second communication node configures candidate frequency domains (e.g., carrier, channel, BWP, etc.) for the first communication node, the first communication node can select the active frequency domain in the following manner.

[0173] For example, the first communication node selects the active frequency domain (e.g., carrier, channel, BWP, etc.) based on the channel preemption results of the first communication node in each frequency domain. The first communication node sorts the frequency domains based on the channel preemption results or measurement results, selecting those with higher channel preemption probabilities; or, it sorts the frequency domains by the number of times the first communication node successfully preempted the channel, or the percentage of successful channel preemption, from largest to smallest, preferably those with a large number of successful channel preemption attempts or a large percentage of successful channel preemption attempts; or, it sorts the frequency domains by received signal strength indication, or channel occupancy rate, from smallest to largest, preferably those with a small received signal strength indication or a low channel occupancy rate.

[0174] In another example, the first communication node can also select to activate several frequency domains (e.g., carrier, channel, BWP, etc.) based on the trigger level. Several activation / selection conditions are set, and the first communication node can select to activate a corresponding number of frequency domains based on the conditions met. For example, if the received signal strength indication or channel occupancy rate is below a first threshold and the uplink latency requirement for the data to be transmitted on the first communication node is less than a second threshold, then the first communication node activates one BWP. The frequency domain of this BWP can be selected according to the method described above for selecting the activated frequency domain based on the result of the first communication node preempting the channel. If the received signal strength indication or channel occupancy rate is below a third threshold and the uplink latency requirement for the data to be transmitted on the first communication node is less than a fourth threshold, then the first communication node activates two BWPs. The activated BWPs are also selected according to the method described above for selecting the activated frequency domain based on the result of the first communication node preempting the channel.

[0175] In this way, when the first communication node is configured with multiple frequency domains (such as BWP, carrier, etc.), the first communication node can decide whether to activate frequency domain resources based on the interference and occupancy of the channel, thus ensuring the reliability of data service transmission.

[0176] Figure 9 This is a flowchart illustrating a measurement method provided in an embodiment of this application, as shown below. Figure 9 As shown, the method includes:

[0177] S901, Second communication node configures measurement information.

[0178] In this embodiment, the second communication node can configure measurement information for the first communication node. The first and second communication nodes can be two different types of communication nodes. For example, the first communication node can be a terminal, and the second communication node can be a base station. That is, this step can configure measurement information for the terminal from the base station.

[0179] S902, The second communication node receives the channel status indication reported by the first communication node.

[0180] In this embodiment, the channel state indication can carry the measurement result measured by the first communication node based on the measurement information. That is, the process of this embodiment can be that after the second communication node configures the measurement information for the first communication node, it can receive the measurement result obtained by the first communication node based on the measurement information.

[0181] In this way, if the second communication node receives the channel status indication reported by the first communication node, it can determine whether the first communication node is being interfered with by information such as interference intensity and interference frequency. If it is confirmed that the first communication node is being interfered with, the first communication node can be scheduled to other frequency domains, thereby ensuring the normal transmission of URLLC services on the first communication node.

[0182] In this embodiment, the measurement information configured by the second communication node may include an indication of whether the first communication node is enabled to perform measurements; or, when the first communication node is enabled to perform measurements, a configured measurement trigger condition; or, the duration of the measurement window and the interval granularity of the measurement window, wherein the duration of the measurement window is a preset duration or multiple measurement moments, and the interval granularity of the measurement window may also be a period of time or multiple measurement moments; or, pre-configured resources; or, the second communication node may configure indication information to explicitly indicate whether the first communication node needs to perform measurements.

[0183] For example, a second communication node can configure measurements for certain first communication nodes via RRC messages to enable the first communication nodes to perform corresponding measurements.

[0184] For example, the RRC message may carry a cell that enables the first communication node to perform a measurement. The cell may be a 1-bit (e.g., 1 for enabling measurement) or an enumeration value (e.g., the enumeration value option is to enable measurement).

[0185] In one example, the presence of certain measurement configurations in the second communication node configuration indicates whether the first communication node is enabled to perform measurements. This could be indicated by the quality of service parameters of the carried service; or by the transmission delay of the carried service; or by whether there is data to be transmitted on the logical channel; or by whether the uplink scheduling request resource corresponding to the logical channel has been triggered; or by whether a first type of configuration grant (type1 configured grant) is configured; or by whether a second type of configuration grant (type2 configured grant) or semi-persistent scheduling (SPS) is activated.

[0186] Optionally, in this embodiment, the second communication node may also be configured with measurement triggering conditions. The configured measurement triggering conditions may include the received signal strength being greater than a signal strength threshold, or the received signal strength being greater than a signal strength threshold for several consecutive measurement times, or the LBT failure rate being greater than a first threshold within a preset time, or the occupancy rate of the measurement channel being greater than a second threshold within a preset time, or the retransmission probability of the data packet being greater than a third threshold.

[0187] When the first communication node is enabled for measurement, if the first communication node determines that the measurement trigger condition has been met, it can perform measurement according to the configured measurement information; otherwise, the first communication node will not perform measurement.

[0188] Furthermore, in this embodiment of the application, the second communication node can also be configured with a first transmission resource. After the first communication node obtains the measurement result, it can report a channel state indication carrying the measurement result through the first transmission resource. That is, the second communication node receives the channel state indication reported by the first communication node through the first transmission resource.

[0189] For example, the first transmission resource configured by the second communication node may include any type of transmission resource: MACCE, PUCCH, SRS, PRACH, UCI.

[0190] In one example, the second communication node can also be configured with enabling information to indicate whether to enable the PDCP duplication function of the first communication node, and / or whether to enable the first communication node to deactivate the PDCP duplication function. That is, the second communication node can jointly configure whether the first communication node has the ability to autonomously activate or deactivate PDCP duplication.

[0191] For example, the second communication node configures two bits in the RRC signaling: 00 represents that the first communication node or logical channel does not have the function of autonomously activating and deactivating PDCP duplication; 01 represents that the first communication node or logical channel has the function of autonomous activation but does not have the function of deactivating PDCP duplication; 10 represents that the first communication node or logical channel has the function of autonomous deactivation but does not have the function of activating PDCP duplication; and 11 represents that the first communication node or logical channel has the function of autonomously activating and deactivating PDCP duplication.

[0192] Accordingly, the second communication node can pre-configure some candidate carriers (such as carrier, channel, BWP, etc.) for the first communication node to support PDCP duplication. The carrier information can be frequency point, index, uplink and downlink resource configuration, etc., and these candidate frequency domains can be used to transmit the copied PDCP SDU.

[0193] In one example, the second communication node can be configured with activation information that indicates whether the first communication node is enabled to activate one or more frequency domain resources. For example, a bit can be configured in the RRC signaling such that 1 represents enabling the first communication node to autonomously activate multiple frequency domain resources, and otherwise disabling it.

[0194] Correspondingly, the second communication node can also be configured with some candidate frequency domains (such as carrier, channel, BWP, etc.). The carrier information can be frequency point, index, uplink and downlink resource configuration, etc., as well as whether to support the activation of multiple frequency domains.

[0195] Figure 10 This is a flowchart illustrating a measurement method provided in an embodiment of this application, as shown below. Figure 10 As shown, the method includes:

[0196] S1001, Second Communication Node Broadcast System Information Block.

[0197] Optionally, the System Information Block (SIB) in the embodiments of this application may include one or more sets of wireless parameter configurations.

[0198] For example, in the case where the SIB includes multiple sets of wireless parameter configurations, each set of wireless parameter configurations may include a parameter configuration index.

[0199] S1002, The second communication node sends a dedicated signaling message to the first communication node.

[0200] In this embodiment, the second communication node and the first communication node are two different types of communication nodes. For example, the second communication node can be understood as a base station, and the first communication node can be understood as a user equipment (UE). In this case, this step can be used to send UE-specific signaling from the base station to the UE.

[0201] For example, the aforementioned dedicated signaling may include any of the following:

[0202] Use SIB configuration parameter indicators, wireless parameter configuration index, and wireless parameter configuration.

[0203] Thus, after receiving the dedicated signaling, if the dedicated signaling includes an "instruction to use SIB configuration parameters," the first communication node uses the radio parameters configured in the SIB; if the dedicated signaling includes a "radio parameter configuration index," the first communication node uses the corresponding radio parameter configuration value in the SIB; and if the dedicated signaling includes "radio parameter configuration," the first communication node uses the radio parameters carried in the received dedicated signaling. In other words, the first communication node can determine the configurable radio parameters based on the SIB broadcast by the second communication node and the dedicated signaling sent.
