[0064] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, third-generation systems (3G for short), LTE systems, fourth-generation systems (4G for short), fifth-generation systems (5G for short), NR systems, and future evolution systems or multiple communication convergence systems. Among them, the 5G system can be a non-standalone (NSA for short) 5G system or a standalone (SA for short) 5G system. The solutions of the embodiments of the present application can also be applied to various new communication systems in the future, such as 6G, 7G, etc.
[0065] The present application mainly relates to the communication between terminal equipment (or simply referred to as terminal) and network equipment. The terminal in the embodiments of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal equipment (Terminal Equipment), wireless communication equipment, user agent or user device. The terminal may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited to this.
[0066] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS for short) (also referred to as a base station device), which is a device deployed in a radio access network (RAN for short) to provide wireless communication functions. For example, in the second generation (2nd-generation, 2G) network, the equipment providing base station functions includes a base transceiver station (BTS), the equipment providing base station functions in the 3G network includes a node B (Node B), the equipment providing base station functions in the 4G network includes an evolved node B (eNB), in the wireless local area network (WLAN), the equipment providing base station functions is an access point (AP), the equipment providing base station functions in NR is the next generation node base station (gNB), and the evolving node B (ng-eNB), wherein the gNB and the terminal communicate using NR technology, the ng-eNB and the terminal communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application also includes a device that provides base station functions in a future new communication system, etc.
[0067] In the prior art, the measurement of beam information and precoding information is performed independently for each cell. The terminal measures the reference signal in a cell and reports a measurement report. The network device determines the optimal beam or precoding matrix for the cell based on the measurement report.
[0068] However, this solution of independent measurement and reporting of each cell cannot guarantee that the signals carried by the optimal beam or precoding matrix of each frequency (such as each cell) in a large bandwidth can be successfully received by the terminal at the same time. If the measurement results at a specific frequency (such as a cell) are applied to other frequencies in the entire bandwidth, the frequency change will cause the beam to diverge or shift, and the array gain will deteriorate, and the beam or precoding matrix at other frequencies cannot be guaranteed to be optimal. Whether it is millimeter wave or future terahertz frequency bands, as the bandwidth increases and the beam narrows, the phenomenon that beams of different frequencies will point in different directions will become more obvious.
[0069] In a large bandwidth communication system, for a terminal that only supports a single radio frequency chain (RFChain), in order to receive beams of various frequencies over a large bandwidth, the terminal's single radio frequency chain needs to support a large beam width to cope with beam deviation, which will increase costs and power consumption. If the measurement results on a certain frequency (such as the main carrier) are directly applied to other frequencies (such as the auxiliary carrier), this solution will result in the transmission performance on other frequencies cannot be guaranteed.
[0070] For example, a network device has a very large array, and multiple sub-arrays support different frequencies. The measurement result of a certain sub-array may not be completely applicable to all sub-arrays.
[0071] For another example, in the integrated synaesthesia technology, the perception and communication resources can be multiplexed using frequency division multiplexing (FDM). If the frequency interval between the perception link and the communication link is too large, the measurement results on the perception link cannot be directly applied to the communication link.
[0072] In view of this, an embodiment of the present application provides a communication method. In the scheme of the embodiment of the present application, the terminal sends a first RS on the first frequency information, wherein the transmission parameters used to send the first RS are determined according to the transmission parameters of the second RS on the second frequency information. With the above scheme, since the transmission parameters of the first RS are determined according to the transmission parameters on the second frequency information, the network device can determine the transmission performance of the transmission parameters on the first frequency information based on the reception quality of the first RS on the basis of determining the optimal transmission parameters on the second frequency information. When the terminal only supports a single radio frequency channel, the network device can determine the optimal beam or precoding matrix and other parameters used by the single radio frequency channel, taking into account the communication performance of the terminal and the network device on the first frequency information and the second frequency information. In addition, in the above scheme, the beam management or CSI measurement on multiple frequency information in a large bandwidth system does not rely on the terminal performing RS measurement on the first frequency information, and therefore, it is also beneficial to reduce the measurement overhead of the terminal.
[0073] First, some nouns involved in the embodiments of the present application are introduced to facilitate understanding by those skilled in the art.
[0074] 1. First Reference Signal (RS) The first RS in the embodiment of the present application is an uplink RS. For example, the first RS may be a sounding reference signal (SRS), but is not limited thereto.

Furthermore, after the terminal determines the second RS through measurement or network indication, the transmission parameters of the second RS may be determined through the transmission indication information of the second RS.

[0082] For example, the beam information may be a reference signal resource indication, wherein the reference signal may be a channel state information reference signal (CSI-RS), and correspondingly, the reference signal resource indication may be a CSI-RS resource indication (CSI-RS Resource Indicator, CRI). Alternatively, the reference signal may also be a synchronization signal block (SSB), and correspondingly, the reference signal resource indication may be an SSB resource indication (SSB RI).

[0084] 4. Sub-interval: The sub-interval in the embodiment of the present application may refer to a part of the above frequency interval.
[0085] Specifically, the frequency interval may be divided into a plurality of parts, wherein each part may be referred to as a sub-interval of the frequency interval.
[0086] For example, if a cell is a large-bandwidth cell, the cell bandwidth may be divided into multiple parts, where each part may be referred to as a sub-interval.

Alternatively, the frequency information may also be understood as the above frequency interval or a sub-interval of a frequency interval or a frequency interval group.
[0089] In the solution of the embodiment of the present application, the RS on the frequency information may refer to an RS whose frequency domain resource location belongs to the frequency interval or sub-interval or frequency interval group indicated by the frequency information.
[0090] Specifically, the first frequency information and the second frequency information in this article are different frequency information.
[0091] In one embodiment of the present application, the first frequency information is the first frequency interval, the second frequency information is the second frequency interval, the first RS is the RS in the first frequency interval, and the second RS is the RS in the second frequency interval. Taking the frequency interval as the cell bandwidth as an example, the first RS may be the RS in cell 1, and the second RS may be the RS in cell 2.
[0092] In another embodiment of the present application, the first frequency information is the first sub-interval, the second frequency information is the second sub-interval, and the first sub-interval and the second sub-interval belong to the same frequency interval. The first RS is the RS on the first sub-interval, and the second RS is the RS on the second sub-interval. Taking the frequency interval as the cell bandwidth as an example, cell 1 is a large bandwidth cell, and the cell 1 bandwidth includes sub-interval 1 and sub-interval 2. The first RS can be the RS on sub-interval 1, and the second RS can be the RS of sub-interval 1.
[0093] In another embodiment of the present application, the first frequency information is the first frequency interval group, the second frequency information is the second frequency interval group, the first RS is the RS on the first frequency interval group, and the second RS is the RS on the second frequency interval group. For example, the frequency interval group is the cell group bandwidth, the first RS may be the RS on cell group 1, and the second RS may be the RS on cell group 2.
[0094] 7. Measured frequency information. In the solution of the embodiment of the present application, the measured frequency information refers to the frequency information of the frequency domain position of the RS resource measured by the terminal. In other words, the measured frequency information refers to the frequency information corresponding to the frequency interval or frequency sub-interval or frequency interval group where the frequency domain position of the RS resource measured by the terminal is located.
[0095] 8. Target information: In the solution of the embodiment of the present application, the target information may refer to information about parameters used by the network device to send a channel or signal to the terminal.
[0096] Exemplarily, the target information may be at least one of the following: beam information, TCI state, source reference signal (source RS) of TCI state, precoding information, MCS information, and rank information.
[0097] In some embodiments of the present application, the terminal uses a single radio frequency channel to transmit signals with a network device on multiple frequency information. In this case, the target information can be used for signal transmission of a single radio frequency channel or a single beam of the terminal.
[0098] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0099] Embodiment 1
[0100] Reference Figure 1 , Figure 1 It is a flow chart of the first communication method in the embodiment of the present application. Figure 1 The communication method shown may include S11. In this application, S in each step number represents a step.
[0101] S11, the terminal sends a first RS to a network device, where the first RS is an RS on the first frequency information; wherein a transmission parameter for sending the first RS is determined according to a transmission parameter of a second RS on the second frequency information.
[0102] For ease of description, the “transmission parameters used to send the first RS” are referred to as “sending parameters of the first RS” hereinafter. Exemplarily, the sending parameters of the first RS may refer to parameters used by the terminal to send the first RS.
[0103] Specifically, the first frequency information and the second frequency information are different frequency information, and the terminal determines the transmission parameters of the first RS based on the transmission parameters of the second RS on the second frequency information.
[0104] The second RS may be a downlink RS. In this case, the transmission parameters of the second RS may be parameters used by the terminal to receive the second RS from the network device on the second frequency information. Before S11, the terminal may determine the parameters used by the terminal to send a channel or signal to the network device on the second frequency information based on the transmission parameters of the second RS and channel reciprocity, inter-frequency correlation, etc., and use the determined parameters used to send a channel or signal to the network device on the second frequency information as the transmission parameters of the first RS.
[0105] Alternatively, the second RS may be an uplink RS. In this case, the transmission parameter of the second RS may be a parameter used by the terminal to send the second RS to the network device on the second frequency information. Further, the terminal may use the transmission parameter of the second RS as the transmission parameter of the first RS.
[0106] In one embodiment of the present application, the second RS may be the source RS of the TCI state indicated by the network device. Exemplarily, the TCI state indicated by the network device may be a public TCI state. Alternatively, the TCI state indicated by the network device may be a TCI state for scheduling the first channel. Among them, the first channel may be any channel for data or signaling transmission between the terminal and the network device, and this embodiment does not limit this. In a specific implementation, the terminal may determine the source RS in the TCI state most recently indicated by the network device as the second RS, or may determine the source RS in the TCI state most recently indicated by the network device for scheduling the first channel as the second RS, and determine the uplink transmit beam or downlink receive beam of the second RS based on the beam information of the second RS.
[0107] In another embodiment of the present application, the second RS may be a downlink RS determined by measuring multiple downlink RSs. For example, the downlink RS may be a CSI-RS, or an SSB, etc., but is not limited thereto. In this case, the second RS may be a downlink RS determined by the terminal through measuring multiple downlink RSs. Specifically, the second RS is an RS transmitted on a downlink RS resource with the best measurement result among multiple downlink RS resources.
[0108] Exemplarily, the network device may pre-configure or indicate the beam information of the second RS. Before S11, the terminal may determine the second RS through measurement or network instructions. The terminal may determine the uplink transmit beam or downlink receive beam of the second RS based on the beam information of the second RS.
[0109] Combine the following Figure 2 A non-limiting description is given of a solution in which the second RS is a downlink RS.
[0110] Reference Figure 2 , Figure 2 It is an interactive schematic diagram of the second communication method in the embodiment of the present application. Figure 2 The method shown may include S21, S22 and S25, optionally, Figure 2 The illustrated method may further include S23 and / or S24.
[0111] S21, the network device sends a downlink RS to the terminal.
[0112] S22: The terminal measures the downlink RS and obtains a measurement report.
[0113] S23, the terminal sends a measurement report to the network device.
[0114] S24, the network device sends first target indication information to the terminal, where the first target indication information is used to indicate the second RS.
[0115] S25, the terminal sends a first RS to the network device.
[0116] In S21, the network device may use multiple downlink RS resources to send downlink RSs, wherein the downlink RSs are all RSs on the second frequency information.
[0117] In a specific implementation, before S21, the network device may also send report configuration information to the terminal, and the report configuration information may be used to configure the terminal to report a measurement report.
[0118] In S22, the terminal may measure RSs transmitted on multiple downlink RS resources, obtain measurement results of each downlink RS resource, and further generate a measurement report. The measurement report may be a beam report, or may also be a CSI report.
[0119] It can be understood by those skilled in the art that the measurement report may include measurement results of multiple downlink RS resources. For example, it may include identifiers of multiple downlink RS resources with better measurement results. It should be noted that this embodiment does not limit the content and reporting method of the measurement report, which may be an existing measurement report. For example, the measurement report may be a report for implementing beam management.
[0120] As a possible implementation, the measurement report type configured by the report configuration information may be an empty report. In this case, after the terminal obtains the measurement report, it may not report the measurement report. The terminal may determine the second RS based on the measurement result, and then determine the transmission parameters of the first RS according to the transmission parameters of the second RS, and then execute S25. That is, in this case, there is no need to execute S23 and S24.
[0121] Specifically, the terminal may determine the second RS resource from the multiple downlink RS resources included in the measurement report. For example, the terminal may determine the downlink RS resource with the best reception quality as the second RS resource, and accordingly, the RS transmitted on the downlink RS resource with the best quality is the second RS. Accordingly, the transmission parameter of the second RS may be the parameter used by the terminal to receive the second RS from the network device.
[0122] Further, the terminal may determine the transmission parameters of the first RS according to the transmission parameters of the second RS, and send the first RS.
[0123] Exemplarily, the downlink RS can be a CSI-RS, and the terminal can measure the CSI-RS transmitted on multiple CSI-RS resources, and then determine the CSI-RS with the best quality as the second RS. Correspondingly, the parameters indicated by the beam information of the CSI-RS with the best quality are the transmission parameters of the second RS.
[0124] It should be noted that the network device configures the beam information of each CSI-RS resource before the terminal measures the CSI-RS on the second frequency information. Therefore, the terminal can determine the beam information of the second RS after determining the second RS. Since the beam information of the second RS can be used to determine the downlink receive beam of the second RS, the terminal can determine the uplink transmit beam of the first RS based on the downlink receive beam of the second RS.
[0125] Alternatively, the measurement report type configured by the report configuration information may not be a null report, in which case S23 and S24 may be executed after S22. Alternatively, S23 may be executed after S22, but S24 may not be executed.
[0126] In S23, the terminal sends a measurement report to the network device. Correspondingly, the network device receives the measurement report. As described above, the measurement report may include measurement results of multiple downlink RS resources. For example, the measurement report may include identifiers of multiple downlink RS resources with better measurement results.
[0127] In a possible implementation, after S23, S24 may not be executed.
[0128] Specifically, after sending the measurement report, the terminal may determine the second RS by itself.
[0129] As described above, if the measurement report includes measurement results of multiple downlink RS resources, the terminal can determine the second RS resource from the multiple downlink RS resources corresponding to the measurement results included in the measurement report. For example, the terminal can determine the downlink RS resource with the best reception quality as the second RS resource, and accordingly, the RS transmitted on the downlink RS resource with the best quality is the second RS.
[0130] In addition, if the measurement report only includes the measurement result of a single downlink RS resource, the terminal may determine the RS transmitted on the downlink resource as the second RS.
[0131] In another possible implementation, S24 may be executed after S23.
[0132] Specifically, after receiving the measurement report, the network device can determine the second RS resource based on the measurement report. That is, the network device can determine the second RS resource from the downlink RS resource corresponding to the measurement result included in the measurement report, and the RS transmitted on the second RS resource is the second RS.
[0133] In S24, the network device sends first target indication information to the terminal, where the first target indication information is used to indicate the second RS. Exemplarily, the first target indication information can be used to indicate the second RS resource, so that the terminal can determine that the RS transmitted on the second RS resource is the second RS.
[0134] Correspondingly, the terminal receives the first target indication information. Based on the first target indication information, the terminal can determine the second RS. Since the network device configures or indicates the transmission parameters of each CSI-RS resource before the terminal measures the CSI-RS on the second frequency information, for example, the network device configures or indicates the transmission parameters of each CSI-RS resource to the terminal through the transmission indication information. To this end, after the terminal determines the second RS, it can determine the transmission parameters of the second RS, thereby further determining the transmission parameters of the first RS.
[0135] Exemplarily, the transmission indication information may be beam information. The network device may configure the beam information of each downlink RS resource (such as the TCI status of each downlink RS resource) before the terminal measures the downlink RS on the second frequency information. After receiving the measurement report, the network device indicates the second RS to the terminal. The terminal may determine the downlink receiving beam of the second RS based on the beam information of the second RS (that is, the downlink receiving beam used to measure the second RS). Furthermore, the terminal may determine the uplink transmitting beam of the first RS based on the downlink receiving beam used to measure the second RS, and use the uplink transmitting beam to send the first RS to the network device on the first frequency information.
[0136] In S24, the first target indication information may directly indicate the second RS, or may also indirectly indicate the second RS.
[0137] Specifically, the network device may directly indicate the second RS to the terminal. Alternatively, the network device may indicate the second RS by means of an indicated TCI state (e.g., a common TCI state, or a TCI state for scheduling the first channel), and the source RS in the TCI state is the second RS. Accordingly, the terminal may determine the source RS in the TCI state indicated by the network device after sending the measurement report as the second RS.
[0138] Continue to refer to Figure 1 After S11, the network device may measure the first RS to obtain the measurement result of the first RS. The network device may determine the parameters used to receive the channel or signal sent by the terminal on the first frequency information based on the measurement result of the first RS, and the network device may subsequently communicate with the terminal on the first frequency information using the determined parameters used to transmit the channel or signal to the terminal on the first frequency information.
[0139] For example, the network device may use different uplink receiving beams to receive the first RS, measure the reception quality of each first RS, and select the best uplink receiving beam therefrom. Thus, the network device may use the determined uplink receiving beam and / or downlink transmitting beam to communicate with the single radio frequency channel of the terminal on the first frequency information.
[0140] It should be noted that the parameters used by the network device to transmit channels or signals to the terminal on the first frequency information and the parameters used by the network device to transmit channels or signals to the terminal on the second frequency information may be the same or different. Taking the beam as an example, the terminal may use the same uplink transmit beam to transmit channels or signals on the first frequency information and the second frequency information, and the network device may use the same or different uplink receive beams to receive channels or signals on the first frequency information and the second frequency information. Correspondingly, the network device may use the same or different downlink transmit beams to transmit channels or signals on the first frequency information and the second frequency information, and the terminal may use the same downlink receive beam to receive channels or signals on the first frequency information and the second frequency information.
[0141] In the scheme described above, the second RS is indicated by the network device or determined by the terminal through measurement, and the transmission parameters of the second RS are the optimal parameters for transmitting the channel or signal on the second frequency information. The terminal determines the optimal parameters for sending the channel or signal to the network device on the second frequency information based on the indication of the network device or the downlink measurement result, and the terminal further sends the first RS on the first frequency information according to the transmission parameters of the second RS. The network device determines the optimal parameters for transmitting the channel or signal on the first frequency information based on the measurement of the first RS, and optimizes and adjusts the parameters of the transmission channel or signal on the first frequency information, thereby taking into account the communication performance of the terminal and the network device on the first frequency information and the second frequency information.
[0142] That is, in the scheme of this embodiment, the terminal sends the first RS based on the result of the beam management or CSI measurement on the second frequency information to implement the beam management or uplink CSI measurement on the first frequency information. Specifically, the terminal further determines the transmission parameters of the first RS based on the transmission parameters of the second RS, and the network device can determine the parameters used for receiving the channel or signal on the first frequency information based on the measurement of the first RS, thereby ensuring the transmission performance of the network device and the terminal on the first frequency information.
[0143] Therefore, the above scheme can take into account the communication performance between the terminal and the network device on the first frequency information and the second frequency information. In particular, when the terminal is a terminal that only supports a single radio frequency channel, the terminal can ensure that the communication performance between the terminal and the network device on the first frequency information and the second frequency information is better while keeping parameters such as beam or precoding unchanged. In the above scheme, the network device performs measurement on the first frequency information to optimize and adjust the parameters of the transmission channel or signal on the first frequency information. The terminal does not need to perform measurement on the first frequency information, so it is also beneficial to reduce the measurement power consumption of the terminal.
[0144] Continue to refer to Figure 1 , the second RS may also be an uplink RS. In a specific implementation, the second RS may be an RS for uplink beam management. Alternatively, the second RS may not be an RS for uplink beam management. For example, the second RS may be used for uplink measurement of antenna switching, or the second RS may be used for uplink measurement of PUSCH based on a codebook or for uplink measurement of PUSCH based on a non-codebook.
[0145] The following is a non-limiting description of a solution in which the second RS is an uplink RS.
[0146] In another embodiment of the present application, the second RS may be an uplink RS. Exemplarily, the second RS may be an uplink RS most recently sent by the terminal. For example, the second RS may be an SRS. In this case, the transmission parameters of the second RS may be parameters used by the terminal to actually send the second RS.
[0147] As a possible implementation, the terminal may send a first RS to the network device at the first frequency information, and send a second RS to the network device at the second frequency information. The transmission parameters of the first RS and the transmission parameters of the second RS are the same. Exemplarily, the uplink transmission parameters of the first RS and the uplink transmission parameters of the second RS are the same.
[0148] Taking the beam as an example, the network device measures the first RS and the second RS respectively to determine the uplink receiving beam on the first frequency information and the uplink receiving beam on the second frequency information.
[0149] Specifically, the terminal may use the same transmission parameters to send the second RS multiple times. For example, the terminal may use the same uplink transmission beam to send the second RS multiple times. The network device may use different uplink reception beams to receive the second RS. Furthermore, the network device measures the received second RS to obtain measurement results of multiple second RSs. Furthermore, based on the measurement results of multiple second RSs, the network device may determine the uplink reception parameters on the second frequency information. For example, the network device may determine the reception beam of the second RS with the best quality as the uplink reception beam on the second frequency information.
[0150] Similarly, the terminal may use the same transmission parameters to send the first RS multiple times. For example, the terminal may use the same uplink transmission beam to send the first RS multiple times. The network device may use different uplink reception beams to receive the first RS. Furthermore, the network device measures the received first RS to obtain measurement results of multiple first RSs. Furthermore, based on the measurement results of multiple first RSs, the network device may determine the uplink reception parameters on the first frequency information. For example, the network device may determine the reception beam of the first RS with the best quality as the uplink reception beam on the first frequency information.
[0151] By adopting the above scheme, the terminal can keep the uplink transmission parameters unchanged (for example, the beam direction of the transmission beam remains unchanged) and send the uplink RS on the first frequency information and the second frequency information respectively. The network device can determine the uplink reception parameters on the first frequency information and the uplink reception parameters on the second frequency information respectively by measuring the uplink RS on the first frequency information and the second frequency information, so that the single RF channel of the terminal can keep the uplink transmission parameters unchanged and communicate with the network device with better performance on both the first frequency information and the second frequency information. In the above scheme, the network device performs the measurement when implementing the beam management of the first frequency information and the second frequency information, which is conducive to reducing the measurement power consumption of the terminal.
[0152] As another possible implementation, the terminal may use different transmission parameters to send the uplink RS multiple times, wherein the uplink RS is the RS on the second frequency information. Specifically, the terminal may use different uplink transmission beams to send the uplink RS on the second frequency information. Furthermore, the network device may receive the uplink RS and measure the received uplink RS to determine the uplink RS with the best quality.
[0153] Further, the network device may indicate the uplink RS with the best quality to the terminal, and the terminal may determine the uplink RS indicated by the network device as the second RS, and determine the transmission parameters of the second RS as the transmission parameters of the first RS.
[0154] Specifically, the terminal uses multiple uplink RS resources to send an uplink RS. After the network device measures the received uplink RS, it can determine that the RS transmitted on the uplink RS resource with the best reception quality is the second RS. Furthermore, the network device can send first target indication information to the terminal, and the first target indication information can be used to indicate the second RS. As described above, the network device can pre-configure or indicate the transmission parameters of each uplink RS to the terminal, so that the terminal can determine the second RS, that is, determine the transmission parameters of the second RS. For example, the network device can directly indicate the second RS to the terminal, or indicate a TCI state, and the source RS in the TCI state is the second RS.
[0155] Further, the terminal may use the transmission parameter of the second RS as the transmission parameter of the first RS to transmit the first RS. Exemplarily, the transmission parameter of the second RS is the uplink transmission beam of the second RS, and the terminal may use the uplink transmission beam of the second RS to transmit the first RS.
[0156] Further, the network device may use different uplink receiving beams to receive the first RS, and measure the received first RS to obtain measurement results of multiple first RSs. Further, based on the measurement results of multiple first RSs, the network device may determine the uplink receiving beam on the first frequency information. For example, the network device may determine the uplink receiving beam of the first RS with the best quality as the uplink receiving beam on the first frequency information.
[0157] By adopting the above scheme, the terminal determines the parameters used to send the channel or signal to the network device on the second frequency information based on the indication of the network device, and the terminal uses the parameters to communicate with the network device with better performance on the second frequency information. In addition, the terminal also uses the above parameters to send the first RS on the first frequency information, and the network device determines the uplink reception parameters on the first frequency information by measuring the first RS to ensure the communication performance on the first frequency information. Therefore, the above scheme enables the single RF channel of the terminal to maintain the beam direction unchanged and communicate with the network device with better performance on both the first frequency information and the second frequency information.
[0158] The above mainly describes the determination of the transmission parameters of the first RS, and the following describes the determination of the first RS resources in detail.
[0159] In one embodiment of the present application, before S11, the network device may send resource indication information to the terminal, and the resource indication information may be used to indicate a first RS resource, where the first RS resource is a resource for sending the first RS. Thus, the terminal may send the first RS on the first RS resource using the transmission parameters determined above. It should be noted that the "first RS resource" in this article refers to a resource for transmitting the first RS, and the "second RS resource" refers to a resource for transmitting the second RS.
[0160] In another embodiment of the present application, the network device may configure associations between RS resources on different frequency information. In the solution of the embodiment of the present application, the RS resources with associations belong to different frequency information.
[0161] In the solution of this embodiment, the network device can configure the association relationship between the first RS resource on the first frequency information and the second RS resource on the second frequency information. The terminal can determine the first RS resource according to the second RS resource and the above association relationship.
[0162] As a possible implementation manner, the network device may configure an association relationship between a first RS resource set and a second RS resource set, wherein the first RS resource set is a resource set to which the first RS resource belongs, and the second RS resource set is a resource set to which the second RS resource belongs.
[0163] Specifically, the network device may send association indication information to the terminal for indicating the association relationship between the first RS resource set and the second RS resource set. That is, the association indication information may be used to indicate the association relationship between the resource set to which the RS resource on the first frequency information belongs and the resource set to which the RS resource on the second frequency information belongs.
[0164] Exemplarily, the association indication information may be carried in the configuration information of the resource set. Specifically, the configuration information of the first RS resource set may carry third association indication information, and the third association indication information may be used to indicate the second RS resource set. For example, the configuration information of the first RS resource set may include an identifier of the second RS resource set. Alternatively, the configuration information of the second RS resource set may carry fourth association indication information, and the fourth association indication information may be used to indicate the first RS resource set. For example, the configuration information of the second RS resource set may include an identifier of the first RS resource set.
[0165] Another example, different from carrying the association indication information in the configuration information of the resource set, the network device can carry the association indication information in an additional indication signaling to indicate the association relationship between the resource sets. The association indication information may include an identifier of a resource set with an association relationship. That is, the association indication information may include an identifier of a first RS resource set and an identifier of a second RS resource set. For example, the association indication information may be carried in a medium access control-control element (MAC CE) signaling.
[0166] In this way, the terminal can obtain the association relationship between the first RS resource set and the second RS resource set.
[0167] Further, any resource in the first RS resource set and any resource in the second RS resource set may have an association relationship. Alternatively, RS resources in the first RS resource set and the second RS resource set with the same order or position may have an association relationship.
[0168] As another possible implementation manner, the network device may configure an association relationship between the first RS resource configuration and the second RS resource configuration.
[0169] Specifically, the network device may send association indication information for indicating the association relationship between the first RS resource configuration and the second RS resource configuration to the terminal. That is, the association indication information may be used to indicate the association relationship between the RS resource configuration on the first frequency information and the RS resource configuration on the second frequency information.
[0170] Exemplarily, the associated indication information may be carried in the RS resource configuration information. Specifically, the first RS resource configuration information may carry the first associated indication information, and the first associated indication information may be used to indicate the second RS resource configuration information. For example, the first RS resource configuration information may include an identifier of the second RS resource configuration. Alternatively, the second RS resource configuration information may carry the second associated indication information, and the second associated indication information is used to indicate the first RS resource configuration information. For example, the second RS resource configuration information may include an identifier of the first RS resource configuration.
[0171] As another example, different from carrying the indication information in the resource configuration information, the network device may carry the association indication information in an additional indication signaling to indicate the association relationship between the resource configurations. The association indication information may include an identifier of the resource configuration having the association relationship. That is, the association indication information may include an identifier of the first RS resource configuration and an identifier of the second RS resource configuration. For example, the association indication information may be carried in the MAC CE signaling.
[0172] Thus, the terminal can learn the association relationship between the first RS resource configuration and the second RS resource configuration.
[0173] Further, any resource in the first RS resource configuration and any resource in the second RS resource configuration may have an association relationship. Alternatively, RS resources with the same order or position in the first RS resource configuration and the second RS resource configuration may have an association relationship. Alternatively, the first RS resource set in the first RS resource configuration and the second RS resource set in the second RS resource configuration are associated one-to-one, and RS resources with the same order or position in the associated first RS resource set and the second RS resource set may have an association relationship.
[0174] As another possible implementation, the association indication information may be used to indicate the association relationship between the first RS resource and the second RS resource. Exemplarily, the association indication information may be carried in the information of the first RS resource to indicate the associated second RS resource, or the association indication information may be carried in the information of the second RS resource to indicate the associated first RS resource. Again exemplarily, the association indication information may be carried in the MAC CE signaling, and the association indication information may include the first RS resource identifier and the second RS resource identifier.
[0175] As another possible implementation, the association indication information may be an association enabling signaling. Specifically, if the value of the enabling information element in the association enabling signaling is 1 or enabled, an association relationship is established between the first RS resource and the second RS resource, or an association relationship is established between the first RS resource configuration and the second RS resource configuration, or an association relationship is established between the first RS resource set and the second RS resource set. If the enabling information element in the association enabling signaling is not configured or has a value of 0 or disabled, the first RS resource and the second RS resource are independent of each other, or the first RS resource configuration and the second RS resource configuration are independent of each other, or the first RS resource set and the second RS resource set are independent of each other.
[0176] From the above, before S11, the terminal can determine the first RS resource based on the second RS resource and the above-mentioned association relationship, and then send the first RS on the first RS frequency information.
[0177] The following is a non-restrictive description of the association relationship between RS resources on different frequency information configured by the network device, and an example is given in which the network device is configured with four frequency information, namely F1, F2, F3 and F4.
[0178] In a first possible implementation, the RS resources associated with the RS resources on different frequency information may belong to different frequency information. For example, the RS resources on F1 are associated with the RS resources on F3, and the RS resources on F2 are associated with the RS resources on F4. In this case, if S11 is to be executed on F1 (that is, F1 is the first frequency information), the terminal can determine the first RS resource based on the RS resources on F3.
[0179] In a second possible implementation manner, RS resources associated with RS resources on different frequency information belong to the same frequency information.
[0180] For example, the RS resources on F2 and the RS resources on F3 are both associated with the RS resources on F1. In this case, if S11 is to be executed on F1 (that is, F1 is the first frequency information), the first RS resource can be determined based on the RS resources on F2, and the first RS resource can be determined based on the RS resources on F3. If S11 is to be executed on F2 (that is, F2 is the first frequency information), the first RS resource can be determined based on the RS resources on F1; if S11 is to be executed on F3 (that is, F3 is the first frequency information), the first RS resource can also be determined based on the RS resources on F1. That is, the transmission parameters on F1 can be used to assist RS transmission on different frequency information.
[0181] Among them, the RS resources associated with RS resources on different frequency information may be different RS resources on the same frequency information. For example, RS resource 1 on F1 is associated with RS resource 3 on F2, and RS resource 2 on F1 is associated with RS resource 4 on F3. When F1 is the first frequency information, the first RS resource on F1 can be determined to be RS resource 1 based on RS resource 3 on F2, or the first RS resource on F1 can be determined to be RS resource 2 based on RS resource 4 on F3. Correspondingly, when F2 is the first frequency information, the first RS resource on F2 can be determined to be RS resource 3 based on RS resource 1 on F1, and when F3 is the first frequency information, the first RS resource on F3 can be determined to be RS resource 4 based on RS resource 2 on F1.
[0182] Alternatively, the RS resources associated with RS resources on different frequency information may be the same RS resource. For example, RS resource 1 on F1 is associated with both RS resource 3 on F2 and RS resource 4 on F3. When F1 is the first frequency information, the first RS resource on F1 can be determined to be RS resource 1 based on RS resource 3 on F2, or the first RS resource on F1 can be determined to be RS resource 1 based on RS resource 4 on F3. Correspondingly, when F2 is the first frequency information, the first RS resource on F2 can be determined to be RS resource 3 based on RS resource 1 on F1; when F3 is the first frequency information, the first RS resource on F3 can be determined to be RS resource 4 based on RS resource 1 on F1.
[0183] Based on the above, the network device can configure the association relationship between RS resources on different frequency information according to actual measurement requirements.
[0184] Continue to refer to Figure 1 Before S11, the network device may also indicate the transmit power of the first RS to the terminal. Specifically, before S11, the network device may send first configuration information to the terminal, and the first configuration information may be used to determine the transmit power of the first RS.
[0185] Exemplarily, the first configuration information may be a power control parameter of the first RS.
[0186] In another exemplary embodiment, the first configuration information may be a power control parameter of the second RS, and the terminal may determine the transmit power of the first RS according to the power control parameter of the second RS. For example, the terminal may use the power control parameter of the second RS as the power control parameter of the first RS, and calculate the transmit power of the first RS. That is, after the terminal determines the second RS, it may calculate the transmit power of the first RS according to the power control parameter of the second RS.
[0187] In a specific implementation, the first configuration information may be carried in a channel or signaling sent by the network device on the second frequency information. Specifically, the first configuration information may be carried in at least one of the following:
[0188] (1) Configuration information of the first RS resource;
[0189] (2) configuration information of the resource set to which the first RS resource belongs;
[0190] (3) Downlink transmission resources in the second frequency information: The downlink transmission resources may refer to a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH), but are not limited thereto.
[0191] Exemplarily, the first configuration information of the downlink transmission resource carried in the second frequency information may also include first frequency indication information, and the first frequency indication information may be used to indicate the first frequency information. Thus, the terminal may determine the power of sending the first RS on the first frequency information according to the first configuration information.
[0192] (4) Configuration information of the second RS resource; specifically, when configuring the second RS resource, the network device may also configure power information of the first RS to be sent on the first RS resource associated with the second RS resource.
[0193] Exemplarily, the configuration information of the second RS resource may include the power control parameter of the first RS.
[0194] In another exemplary embodiment, the configuration information of the second RS resource may include the power control parameter of the second RS, and the terminal may determine the power control parameter of the first RS according to the power control parameter of the second RS. In this solution, the configuration information of the second RS resource may not explicitly include the power control parameter of the first RS. In this case, the first configuration information may be the power control parameter of the second RS.
[0195] (5) Configuration information of the second RS resource set; that is, when configuring the second RS resource set, the network device may also configure power information of sending the first RS on the first RS resource associated with the second RS resource.
[0196] Exemplarily, the configuration information of the second RS resource set may include the power control parameters of the first RS.
[0197] In another exemplary embodiment, the configuration information of the second RS resource set may include a power control parameter of the second RS, and the terminal may determine the power control parameter of the first RS according to the power control parameter of the second RS. (6) First target indication information, wherein the first target indication information is used to indicate the second RS; specifically, the first target indication information may include the power control parameter of the first RS, and / or the first target indication information may include the power control parameter of the second RS.
[0198] In other embodiments, the first target indication information may not include the power control parameters of the first RS and / or the second RS. The power control parameters of the second RS may be configured or indicated by the network device before indicating the second RS (e.g., before the terminal or the network device transmits the second RS). After the terminal determines the second RS, it can determine the power control parameters of the second RS, thereby being able to determine the transmission power of the first RS based on the power control parameters of the second RS.
[0199] (7) second configuration information, where the second configuration information is used to configure or indicate transmission parameters of the second RS;
[0200] Specifically, if the second RS is a downlink RS, the network device can configure or indicate the transmission parameters of multiple downlink RSs to the terminal in advance (that is, before the terminal measures the downlink RS), wherein the configuration information or indication information of the transmission parameters of each downlink RS may include the power control parameters of the downlink RS and / or the power control parameters of the first RS associated with the downlink RS.
[0201] Similarly, if the second RS is an uplink RS, the network device can configure or indicate the transmission parameters of multiple uplink RSs to the terminal in advance (that is, before the terminal sends the uplink RS), wherein the configuration information or indication information of the transmission parameters of each uplink RS may include the power control parameters of the uplink RS and / or the power control parameters of the first RS associated with the uplink RS.
[0202] In the scheme of this embodiment, after the terminal determines the second RS, if the second configuration information includes the power control parameters of the first RS, the terminal can directly determine the power control parameters of the first RS; if the second configuration information does not explicitly include the power control parameters of the first RS, the power control parameters of the second RS can be used as the power control parameters of the first RS.
[0203] (8) Report configuration information, where the report configuration information is used to configure a measurement report corresponding to the second frequency information.
[0204] For example, in Figure 2In the illustrated solution, the network device may send report configuration information to the terminal, and the report configuration information may also include first configuration information. For example, the report configuration information may include the power control parameters of the first RS. For another example, the report configuration information may include the power control parameters of the second RS, and the terminal may determine the power control parameters of the first RS based on the power control parameters of the second RS.
[0205] In addition, before S11, the terminal may also determine the transmission timing of the first RS. Correspondingly, the network device may also determine the transmission timing of the first RS before S11. The transmission timing of the first RS is the transmission time of the first RS. Alternatively, the transmission timing may also be understood as a transmission time window or a starting time domain position of a transmission time window, but is not limited thereto. The actual transmission time of the first RS may be determined based on the first RS resource and transmission timing mentioned above. It should be noted that since the first RS is an uplink RS, for the terminal, the transmission timing of the first RS refers to the sending timing of the first RS, and for the network device, the transmission timing of the first RS refers to the receiving timing of the first RS.
[0206] Specifically, the transmission timing of the first RS is determined according to the first moment and the time interval, wherein the time interval may be pre-configured by the network device, or may be defined by a protocol, which is not limited in this embodiment.
[0207] Specifically, the terminal and / or the network device may first determine the first moment, and then determine the transmission timing of the first RS according to the first moment and the time interval. In a specific implementation, the time interval may include multiple first time units, or the time interval may include multiple second time units. It should be noted that in the solution of the embodiment of the present application, the second time unit includes multiple first time units. For example, the first time unit may be a symbol, the second time unit may be a slot, etc., but is not limited thereto.
[0208] In a first possible implementation, the first moment may be any first time unit among multiple first time units for transmitting the second RS, or the first moment may be a default first time unit among multiple first time units for transmitting the second RS. The default first time unit may refer to the first time unit or the last time unit among the multiple first time units, but is not limited thereto.
[0209] Exemplarily, the first moment can be determined according to the configuration information of the second RS resource, or the first moment can be determined according to the trigger instruction of the second RS. That is, the first moment can be the first time unit indicated by the configuration information or the trigger instruction of the second RS. Among them, the configuration information of the second RS can be a signaling for configuring the terminal to receive or send the second RS; the trigger instruction of the second RS can be a signaling for triggering the terminal to receive or send the second RS.
[0210] In a second possible implementation, the first moment may be a first time unit for transmitting configuration information of the second RS resource. Specifically, for a terminal, the first moment may be a first time unit for the terminal to receive configuration information of the second RS resource, and for a network device, the first moment may be a first time unit for sending configuration information of the second RS resource. More specifically, the first moment may be any first time unit among a plurality of first time units for transmitting configuration information of the second RS resource or a default first time unit.
[0211] In a third possible implementation, the first moment may be a first time unit for transmitting a trigger instruction of the second RS. Specifically, for a terminal, the first moment may be a first time unit for the terminal to receive a trigger instruction of the second RS, and for a network device, the first moment may be a first time unit for sending a trigger instruction of the second RS. More specifically, the first moment may be any first time unit among a plurality of first time units for transmitting a trigger instruction of the second RS or a default first time unit.
[0212] In a fourth possible implementation, the first moment may be a first time unit for transmitting report configuration information, wherein the report configuration information may be used to configure a measurement report corresponding to the second frequency information. Specifically, for a terminal, the first moment may be a first time unit for the terminal to receive the report configuration information, and for a network device, the first moment may be a first time unit for sending the report configuration information. More specifically, the first moment may be any first time unit among a plurality of first time units for transmitting the report configuration information or a default first time unit. For more information about the measurement report and report configuration information corresponding to the second frequency information, please refer to the above description of Figure 2 Detailed description.
[0213] In a fifth possible implementation, the first moment may be a first time unit for transmitting a report trigger instruction, wherein the report trigger instruction is used to trigger a measurement report corresponding to the second frequency information. Specifically, for a terminal, the first moment may be a first time unit for the terminal to receive a report trigger instruction, and for a network device, the first moment may be a first time unit for sending a report trigger instruction. More specifically, the first moment may be any first time unit among a plurality of first time units for transmitting a report trigger instruction or a default first time unit.
[0214] In a sixth possible implementation, the first moment may be a first time unit for transmitting a measurement report corresponding to the second frequency information. Specifically, for a terminal, the first moment may be a first time unit for the terminal to send a measurement report corresponding to the second frequency information, and for a network device, the first moment may be a first time unit for receiving a measurement report corresponding to the second frequency information. More specifically, the first moment may be any first time unit among a plurality of first time units for transmitting a measurement report corresponding to the second frequency information or a default first time unit.
[0215] Further, the transmission timing of the first RS may be the second time unit where the first time unit determined by the first moment and the time interval is located. For example, the first moment is the mth symbol in time slot n, and the first time unit determined according to the first moment and the time interval is the m'th symbol in time slot n', then the transmission timing of the first RS is time slot n'.
[0216] Alternatively, the transmission timing of the first RS may be the next second time unit of the second time unit where the first time unit determined according to the first moment and the time interval is located. For example, the first moment is the mth symbol in time slot n, and the first time unit determined according to the first moment and the time interval is the m'th symbol in time slot n', then the transmission timing of the first RS is time slot n'+1.
[0217] From the above, the solution provided by this embodiment assists the RS measurement on the first frequency information based on the RS measurement or indication on the second frequency information, so as to optimize and adjust the parameters of the transmission channel or signal on the first frequency information while ensuring the optimal parameters of the transmission channel or signal on the second frequency information, so as to take into account the communication performance of the terminal and the network device on the first frequency information and the second frequency information. In particular, when the terminal only supports a single radio frequency channel, the single radio frequency channel can keep the parameters for sending the channel or signal unchanged, and communicate with the network device with better performance on both the first frequency information and the second frequency information.
[0218] Embodiment 2
[0219] Reference Figure 3 , Figure 3 is a flow chart of the third communication method in the embodiment of the present application. Figure 3 As shown, Figure 3 The method shown may include S32. Optionally, Figure 3 The illustrated method may further include one or more of S31 , S33 , and S34 .
[0220] S31, the terminal determines an evaluation result corresponding to the predicted frequency information according to the measurement result corresponding to the measured frequency information.
[0221] S32, the terminal sends an inter-frequency measurement report to the network device, where the inter-frequency measurement report includes at least one of the following: an evaluation result corresponding to the predicted frequency information, compensation information, and a measurement result corresponding to the measured frequency information;
[0222] S33, determining an evaluation result corresponding to the predicted frequency information according to the measurement result corresponding to the measured frequency information.
[0223] S34, the network device sends second target indication information to the terminal, where the second target indication information is used to indicate target information corresponding to at least one frequency information.
[0224] Specifically, in a large bandwidth system, a network device can configure multiple frequency information for a terminal, and the network device expects to determine target information on multiple frequency information based on the cross-frequency measurement report, wherein a portion of the multiple frequency information may be measured frequency information, and another portion of the frequency information may be predicted frequency information.
[0225] It should be noted that the “predicted frequency information” in this embodiment refers to frequency information that the terminal does not perform measurement on.
[0226] Exemplarily, the network device may be configured with a measurement frequency set and a prediction frequency set, the measured frequency information may belong to the measurement frequency set, and the prediction frequency information may belong to the prediction frequency set. For the frequency information belonging to the measurement frequency set, the terminal may determine the measurement result corresponding to the frequency information through measurement. For the frequency information belonging to the prediction frequency set, the evaluation result corresponding to the frequency information may be determined through the scheme in the embodiment of the present application.
[0227] As another example, the measured frequency information may be frequency information associated with resource information, and the predicted frequency information may be frequency information not associated with resource information. It should be noted that the association between resource information and frequency information may mean that the frequency domain position corresponding to the resource information belongs to the frequency information.
[0228] Specifically, before S31, the network device may send report configuration information to the terminal, and the report configuration information is used to configure the cross-frequency measurement report. Among them, the report configuration information may be associated with K resource information, wherein K may be a positive integer, and the resource information may refer to any one of the following: RS resource configuration information, RS resource set, RS resource. For example, the report configuration information may include K resource information or identifiers of K resource information, thereby, the terminal may determine the K resource information associated with the report configuration information. For another example, the network device may send a first indication information to the terminal, and the first indication information may be used to indicate the association relationship between the report configuration information and the resource information. Specifically, the first indication information may include an identifier of the report configuration information and identifiers of the K resource information, thereby, the terminal may determine the report configuration information and the K resource information associated with the report configuration information, and the frequency information to which the frequency domain positions corresponding to the K resource information belong may be the measured frequency information.
[0229] As a possible implementation, before S31, the network device may send measurement indication information to the terminal, and the measurement indication information may be used to indicate the measured frequency information. Thus, the terminal may perform measurement on the measured frequency information indicated by the network device, and determine the measurement result corresponding to the measured frequency information. For other frequency information other than the measured frequency information, the scheme provided in the embodiment of the present application may be used to determine the evaluation result.
[0230] As another possible implementation, the measured frequency information may be default frequency information. Specifically, the measured frequency information may be default frequency information among multiple frequency information configured by the network device. The default frequency information may refer to the frequency information with the lowest frequency domain position, but is not limited thereto.
[0231] Exemplarily, when a network device configures multiple frequency information, the multiple frequency information can be divided to obtain multiple frequency information sets, the default frequency information in each frequency information set is the measured frequency information, and the other frequency information in the frequency information set except the default frequency information is the predicted frequency information.
[0232] In a specific implementation, different frequency information may have an association relationship. The evaluation result corresponding to the predicted frequency information may be determined based on the measurement result corresponding to the measured frequency information associated with the predicted frequency information. Each measured frequency information may be associated with one or more predicted frequency information. In addition, the predicted frequency information associated with different measured frequency information may be the same or different.
[0233] Specifically, the network device may configure the association relationship between frequency information to the terminal. More specifically, before S31, the network device may send a second indication information to the terminal, and the second indication information may be used to indicate the association relationship between the frequency information. Alternatively, the second indication information may be used to indicate the association relationship between RS resources on different frequency information, and the terminal may determine the association relationship between the frequency information where the RS resources are located based on the association relationship between the RS resources. For example, the network device may configure RS resources on different frequency information to be centrally sorted or RS resources in the same position may have an association relationship.
[0234] Exemplarily, when a network device can be configured with multiple frequency information, the multiple frequency information can be divided to obtain multiple frequency information sets, and the frequency information belonging to the same frequency information set can have an association relationship. For example, the evaluation result corresponding to the frequency information not associated with the resource information in the frequency information set can be determined based on the measurement results corresponding to one or more frequency information associated with the resource information in the same frequency information set.
[0235] More specifically, for a certain predicted frequency information, the measured frequency information associated with the predicted frequency information may be at least one of the following:
[0236] (1) Default frequency information among a plurality of frequency information associated with resource information in a frequency information set to which the predicted frequency information belongs.
[0237] (2) Any one or more frequency information associated with resource information in the frequency information set to which the predicted frequency information belongs.
[0238] (3) The frequency information that is closest in frequency to the resource information in the frequency information set to which the predicted frequency information belongs.
[0239] (4) Frequency information of all associated resource information in the frequency information set to which the predicted frequency information belongs.
[0240] Before S31, the terminal may measure the RS resources on the measured frequency information to obtain the measurement result corresponding to the measured frequency information. That is, the measurement result corresponding to the measured frequency information refers to the measurement result of the RS resources on the measured frequency information. For example, the RS resources on the measured frequency information may be the RS resources determined by the resource information associated with the measured frequency information. Among them, the measurement result corresponding to the measured frequency information may be used to determine the target information on the measured frequency information.
[0241] In S31, the terminal may determine an evaluation result corresponding to the predicted frequency information according to the measurement result corresponding to the measured frequency information.
[0242] Specifically, the measurement result may include at least one of the following: beam information, CSI, quality information, and beam-related information. Among them, the quality information may be information about the transmission quality of the reference signal. Exemplarily, when the measurement result includes beam information, the quality information may include reference signal received power (RSRP) and / or signal to interference plus noise ratio (SINR). Another exemplary case is that when the cross-frequency measurement report includes CSI, the quality information may include CQI and / or RI. Among them, the beam-related information may be information used for beamforming, for example, it may be at least one of the following: beam identification information, beam angle information, beam shape information, beam pattern information, beam direction (boresight direction) information (such as horizontal angle and vertical angle), beam width (beam width), beam phase information.
[0243] Similar to the measurement results, the evaluation results corresponding to the predicted frequency information (such as the first predicted frequency information and the second predicted frequency information) can be used to determine the target information on the predicted frequency information. Specifically, the evaluation results may include at least one of the following: beam information, CSI, quality information, beam-related information. Unlike the measurement results, the evaluation results are not obtained through measurement, but are inferred based on the measurement results corresponding to other frequency information.
[0244] In a possible implementation manner, the evaluation result corresponding to the predicted frequency information may be determined according to the compensation information and the measurement result corresponding to the measured frequency information.
[0245] Exemplarily, the compensation information may include at least one of the following: phase offset information, angle offset information, reference signal resource index offset, CQI offset, precoding matrix index offset, rank index offset, beam width offset, quality offset information, RSRP offset value, signal-to-noise ratio SINR offset value. It should be noted that the compensation information may be a positive value or a negative value.
[0246] For example, F1 is the measured frequency information, the measurement result of F1 includes CRI1, the compensation information is the reference signal resource index offset, and CRI2 determined by CRI1 and the reference signal resource index offset is the CRI on the target frequency information F2.
[0247] For another example, F1 is the measured frequency information, the measurement result of F1 includes RSRP1, the compensation information may be an RSRP offset value, and RSRP2 determined according to RSRP1 and the RSRP offset value is the RSRP on the target frequency information F2.
[0248] The compensation information may be pre-defined by the protocol.
[0249] Alternatively, the compensation information may be pre-configured by the network device. Specifically, before S31, the network device may send compensation configuration information to the terminal, and the compensation configuration information is used to configure the compensation information. Specifically, the compensation information configured by the compensation configuration information may include at least one of the following: compensation information corresponding to the predicted frequency information; compensation information corresponding to the measured frequency information.
[0250] Alternatively, the compensation information may be determined by the terminal. For example, the terminal may determine the compensation information by pre-calibration, loosening the beam width, and the like. For another example, the compensation information may be calculated using a first model deployed at the terminal. Among them, the first model may be an artificial intelligence (AI) model or a machine learning (ML) model. For specific details about the use of the first model to calculate the compensation information, please refer to the relevant description of the first model below.
[0251] In another possible implementation, the evaluation result corresponding to the predicted frequency information can be determined based on the measurement result corresponding to the measured frequency information. For example, the measurement result corresponding to the measured frequency information can be directly used as the evaluation result corresponding to the predicted frequency information. For another example, the measurement result corresponding to the measured frequency information can be input into the first model to obtain the evaluation result corresponding to the predicted frequency information.
[0252] In a specific implementation, the compensation information corresponding to different measured frequency information may be the same or different. Alternatively, the compensation information corresponding to the same measured frequency information may be the same or different. Exemplarily, the compensation information corresponding to the measurement results of different RS resources on the same measured frequency information may be the same or different.
[0253] In addition, the compensation information corresponding to different prediction frequency information may be the same or different. Alternatively, the compensation information corresponding to the same prediction frequency information may be the same or different.
[0254] It should be noted that the correspondence between the predicted frequency information and the compensation information refers to the compensation information being used to determine the evaluation result corresponding to the predicted frequency information. The correspondence between the measured frequency information and the compensation information refers to the compensation information being used together with the measurement result corresponding to the measured frequency information to determine the evaluation result of the predicted frequency information.
[0255] As described above, in S31, the terminal may determine the evaluation result corresponding to the predicted frequency information based on the measurement result corresponding to the measured frequency information.
[0256] In S32, the terminal sends an inter-frequency measurement report to the network device, and the inter-frequency measurement report may include an evaluation result corresponding to the predicted frequency information. Thus, after receiving the inter-frequency measurement report, the network device may determine the evaluation result corresponding to the predicted frequency information.
[0257] In a possible implementation, after obtaining the measurement result corresponding to the measured frequency information, the terminal may not need to execute S31. Accordingly, after receiving the cross-frequency measurement report, the network device may determine the evaluation result corresponding to the predicted frequency information according to the measurement result corresponding to the measured frequency information and the compensation information.
[0258] Specifically, the cross-frequency measurement report may include a measurement result corresponding to the measured frequency information. In S33, the network device may determine an evaluation result corresponding to the predicted frequency information according to the measurement result corresponding to the measured frequency information.
[0259] Exemplarily, the cross-frequency measurement report may include compensation information corresponding to the predicted frequency information and measurement results corresponding to the measured frequency information.
[0260] For example, assuming that the predicted frequency information is F2, and the measured frequency information associated with F2 is F1, the cross-frequency measurement report may include the following content: {(CRI1, delta1)(CRI2, delta2)}, where CRI1 and CRI2 are the measurement results on F1, and delta1 and delta2 are the compensation information corresponding to the predicted frequency information F2.
[0261] Furthermore, the cross-frequency measurement report may further include first frequency indication information, wherein the first frequency indication information may be used to indicate measured frequency information corresponding to the compensation information in the cross-frequency measurement report.
[0262] For example, assuming that the predicted frequency information is F2, and the measured frequency information associated with F2 is F1 and F3, the cross-frequency measurement report may include the following content:
[0263] {(CRI1,delta1,F1)(CRI2,delta2,F3)(CRI3,delta1,F1)(CRI4,delta2,F3)}.
[0264] Among them, CRI1 and CRI3 are the measurement results corresponding to F1, CRI2 and CRI4 are the measurement results corresponding to F3, among them, delta1 is the compensation information corresponding to the measured frequency information F1, delta2 is the compensation information corresponding to the measured frequency information F2, and delta1 and delta2 are both used to determine the evaluation result of the predicted frequency information F2.
[0265] In a specific implementation, if the measured frequency information corresponding to the multiple compensation information in the cross-frequency measurement report is the same, the cross-frequency measurement report may not include the first frequency indication information. The multiple compensation information may be the same or different.
[0266] For example, continuing the above example, assuming that the predicted frequency information is F2, and the measured frequency information associated with F2 is F1, the cross-frequency measurement report may include the following content: {(CRI1, delta1)(CRI2, delta2)}. Among them, CRI1 and CRI2 are the measurement results on F1, delta1 and delta2 are the compensation information corresponding to the measured frequency information F1, and the cross-frequency measurement report may not include the first frequency indication information.
[0267] In addition, if the inter-frequency measurement report includes multiple compensation information corresponding to multiple measured frequency information, that is, the measured frequency information corresponding to the multiple compensation information in the inter-frequency measurement report is different, the inter-frequency measurement report may include the first frequency indication information.
[0268] For example, assuming that the predicted frequency information is F2, and the measured frequency information associated with F2 is F1 and F3, the cross-frequency measurement report may include the following content:
[0269] {(CRI1,delta1,F1)(CRI2,delta2,F3)(CRI3,delta1,F1)(CRI4,delta3,F3)}.
[0270] Among them, CRI1 and CRI3 are the measurement results corresponding to F1, CRI2 and CRI4 are the measurement results corresponding to F3, and delta1, delta2 and delta3 are the compensation information corresponding to the predicted frequency information F2. CRI1 and CRI3 are the measurement results of RS resource 1 and RS resource 3 on F1, respectively. The compensation information corresponding to CRI1 and CRI3 is the same, both delta1. CRI3 and CRI4 are the measurement results of RS resource 2 and RS resource 4 on F3, respectively. The compensation information corresponding to CRI2 and CRI4 is different, delta2 and delta3, respectively. In this example, delta1 is the compensation information corresponding to F1, delta2 and delta3 are the compensation information corresponding to F3, and the cross-frequency measurement report may include the first frequency indication information.
[0271] Further, the inter-frequency measurement report may also include second frequency indication information, wherein the second frequency indication information may be used to indicate predicted frequency information corresponding to the compensation information in the inter-frequency measurement report.
[0272] For example, assuming that the predicted frequency information is F2 and F3, and the measured frequency information associated with F2 and F3 is F1, the cross-frequency measurement report may include the following:
[0273] {(CRI1,delta1,F2)(CRI2,delta2,F2)(CRI3,delta3,F3)(CRI4,delta4,F3)}
[0274] Among them, CRI1, CRI2, CRI3 and CRI4 are all the measurement results of F1, delta1 and delta2 are the compensation information corresponding to F2, based on CRI1 and delta1, the evaluation result corresponding to F2 can be determined, based on CRI2 and delta2, the evaluation result corresponding to F2 can be determined. delta3 and delta4 are the compensation information corresponding to F3. Based on CRI3 and delta3, the evaluation result corresponding to F3 can be determined, based on CRI4 and delta4, the evaluation result corresponding to F3 can be determined.
[0275] In a specific implementation, the compensation information corresponding to different predicted frequency information may be the same or different. Specifically, if the predicted frequency information corresponding to the compensation information in the cross-frequency measurement report is the same, for example, the cross-frequency measurement report may include multiple compensation information corresponding to a single predicted frequency information, then the cross-frequency measurement report may not include the second frequency indication information. Among them, the multiple compensation information may be the same or different.
[0276] For example, continuing the above example, assuming that the predicted frequency information is F2, and the measured frequency information associated with F2 is F1, the cross-frequency measurement report may include the following content: {(CRI1, delta1)(CRI2, delta2)}. Among them, CRI1 and CRI2 are the measurement results on F1, delta1 and delta2 are the compensation information corresponding to the predicted frequency information F2, and the cross-frequency measurement report may not include the second frequency indication information.
[0277] If the predicted frequency information corresponding to the compensation information in the cross-frequency measurement report is different, for example, the cross-frequency measurement report may include multiple compensation information corresponding to multiple predicted frequency information, then the cross-frequency measurement report may include the second frequency indication information. The multiple compensation information may be the same or different.
[0278] In S33, the network device may determine the evaluation result corresponding to the predicted frequency information based on the measurement result corresponding to the measured frequency information. Specifically, the network device may determine the evaluation result corresponding to the predicted frequency information based on the compensation information and the measurement result corresponding to the measured frequency information in the cross-frequency measurement report. It should be noted that the compensation information used by the network device may be the compensation information carried in the cross-frequency measurement report, or may be the compensation information determined by the network device itself.
[0279] For example, the compensation information may be calculated using a second model deployed on the network device. The second model may be an AI model or an ML model. For details on using the second model to calculate the compensation information and / or the evaluation results, please refer to the relevant description of the second model below.
[0280] Alternatively, the network device may determine the evaluation result corresponding to the predicted frequency information based on the measurement result corresponding to the measured frequency information. For example, the measurement result corresponding to the measured frequency information may be directly used as the evaluation result corresponding to the predicted frequency information. For another example, the measurement result corresponding to the measured frequency information may be input into the second model to obtain the evaluation result corresponding to the predicted frequency information.
[0281] For specific contents of the compensation information and determination of the evaluation result corresponding to the predicted frequency information based on the compensation information and the measurement result corresponding to the measured frequency information, reference may be made to the relevant description above.
[0282] Furthermore, the network device may determine target information corresponding to multiple frequency information. Specifically, the network device may determine target information corresponding to the predicted frequency information based on the evaluation result corresponding to the predicted frequency information, and determine target information corresponding to the measured frequency information based on the measurement result corresponding to the measured frequency information.
[0283] That is to say, the network device can determine the target information corresponding to each frequency information based on the cross-frequency measurement report, and the network device can transmit signals with the terminal on this set of frequency information based on the target information corresponding to each frequency information, and the communication performance on each frequency information is better. In other words, the network device can transmit signals with the terminal on multiple frequency information and can achieve beam alignment in high frequency bands.
[0284] Further, S34 may be executed.
[0285] Specifically, in S34, the network device may send second target indication information to the terminal, and the second target indication information may be used to indicate target information corresponding to at least one frequency information. It should be noted that the target information corresponding to different frequency information may be the same, or the target information corresponding to different frequency information may be different.
[0286] Furthermore, the terminal can determine the target information corresponding to at least one frequency information based on the second target indication information. Thus, the terminal can learn the beam information or precoding information etc. used by the network device to transmit channels or signals on multiple frequency information.
[0287] Furthermore, the terminal may determine at least one of the following based on the target information corresponding to the multiple frequency information: beam information, TCI state, precoding information, MCS information, and rank information. Among them, one or more of the beam information, TCI state, precoding information, MCS information, and rank information are used for signal transmission of a single RF channel of the terminal.
[0288] As described above, the target information may be beam information, TCI status, source RS of TCI status, etc. After receiving the second target indication information, the terminal may determine the beam adopted by the terminal according to the target information corresponding to each frequency information, for example, a terminal that only supports a single RF channel determines the beam adopted by the terminal. The beam may be a downlink receive beam or an uplink transmit beam adopted by a single RF channel of the terminal. For example, the single RF channel of the terminal receives a signal sent by a network device on multiple frequency information through the determined downlink receive beam, wherein the downlink transmit beam used by the network device to send a signal on multiple frequency information may be the same beam or different beams.
[0289] As mentioned above, the target information may be precoding information, MCS information, and rank information. After receiving the second target indication information, the terminal may perform signal transmission with the network device through a single radio frequency channel according to the target information corresponding to each frequency information.
[0290] From above, Figure 3 In the scheme shown, the terminal sends a cross-frequency measurement report to the network device, and the network device can obtain the measurement results or evaluation results on multiple frequency information, so as to further determine the beam information, precoding information, modulation and coding scheme information, rank information, etc. on each frequency information, so that the terminal can communicate with the network device with better performance on multiple frequency information, thereby improving the overall performance of the large bandwidth system. In addition, the target information corresponding to some frequency information in the multiple frequency information is not obtained based on the measurement results, but is inferred based on the measurement results corresponding to other frequency information. The use of such a scheme is conducive to further reducing the measurement power consumption of the terminal.
[0291] As described above, the terminal may be deployed with a first model. At least a portion of the cross-frequency measurement report may be calculated by the first model.
[0292] Specifically, the terminal may use the first model to calculate the first prediction information based on the measurement information to obtain the cross-frequency measurement report. That is, the measurement information is the input of the first model, and the first prediction information is the output of the first model.
[0293] Specifically, the measurement information may include at least one of the following:

In practical applications, the measurement information may include information corresponding to multiple first measured frequency information, and the measurement information may also include information of multiple first RS resources on the first measured frequency information.
[0304] Furthermore, the first prediction information may include at least one of the following:
