Abstract
Description
Technical Field
[0001] This application relates to the field of communication technologies, and in particular, to a method for reporting CLI-RSSI and a communication device. Background Art
[0002] In many scenarios of communication, it is necessary to measure the interference signal strength. For example, when a terminal device in the serving cell performs cell selection, it needs to measure the interference signal strength of neighboring cells. The network configures measurement resources, which are usually the resources for the terminal devices in neighboring cells to send signals. The terminal device in the serving cell measures the signal output power on the measurement resources, so as to determine the interference signal strength of the terminal devices in neighboring cells on this resource when sending signals. With the rapid growth of the uplink service demand, higher requirements are put forward for the uplink coverage, rate, and delay. The full-duplex technology can perform uplink transmission and downlink transmission simultaneously at the same time. For example, sub-band full-duplex provides an opportunity for the enhancement of uplink services compared with the existing time division duplex (TDD) system that pays more attention to downlink transmission. However, how to determine the interference in the sub-band full-duplex system is an urgent problem to be solved. Summary of the Invention
[0003] Embodiments of this application provide a method for reporting CLI-RSSI and a communication device, which can realize the measurement and reporting of CLI-RSSI in a sub-band full-duplex system, so as to determine the cross-link interference in the sub-band full-duplex system.
[0004] In a first aspect, embodiments of this application provide a method for reporting CLI-RSSI, which is applied to a first communication device. The method includes:
[0005] Measure a first CLI-RSSI on a first transmission resource, where the first CLI-RSSI is the output power of the signal sent by a second communication device on a second transmission resource on the first transmission resource. The second transmission resource is located in an uplink sub-band, the first transmission resource is located in a non-uplink sub-band, or the second transmission resource is located in a downlink sub-band, and the first transmission resource is located in a non-downlink sub-band;
[0006] Determine a first reporting value according to the first CLI-RSSI;
[0007] Send the first reporting value.
[0008] Based on the description of the first aspect, the first transmission resource used by the first communication device for measurement and the second transmission resource for the second communication device to send signals may be respectively in the uplink sub-band and the non-uplink sub-band, or respectively in the downlink sub-band and the non-downlink sub-band, so as to facilitate the determination of cross-link interference in the sub-band full-duplex system and realize the measurement and reporting of CLI-RSSI in the sub-band full-duplex system.
[0009] In a possible implementation, the non-uplink sub-band includes a downlink sub-band and / or a guard band;
[0010] The non-downlink sub-band includes an uplink sub-band and / or a guard band.
[0011] Implementing this method, the first communication device can measure CLI-RSSI on the transmission resources of the downlink sub-band and / or the guard band, so as to determine the CLI-RSSI generated by the transmission on the uplink sub-band on the downlink sub-band and / or the guard band. Alternatively, the first communication device can also measure CLI-RSSI on the transmission resources of the uplink sub-band and / or the guard band, so as to determine the CLI-RSSI generated by the transmission on the downlink sub-band on the uplink sub-band and / or the guard band.
[0012] In a possible implementation, the determining the first reporting value according to the first CLI-RSSI includes:
[0013] Determining a second CLI-RSSI according to the first CLI-RSSI, where the second CLI-RSSI is the CLI-RSSI on X resource units, and X is a natural number;
[0014] Determining the first reporting value according to the second CLI-RSSI.
[0015] Implementing this method, the first CLI-RSSI measured on the first transmission resource is uniformly converted into the CLI-RSSI on X resource units, so as to report the measured CLI-RSSI based on a unified benchmark, which is convenient for the receiving end to compare.
[0016] In a possible implementation, the first reporting value is the reporting value corresponding to the CLI-RSSI measurement range where the second CLI-RSSI is located and at least one parameter associated with the first communication device. The at least one parameter associated with the first communication device includes the sub-band type of the non-uplink sub-band or the non-downlink sub-band, and / or the scenario where the first communication device is located;
[0017] The sub-band type of the non-upper sub-band is a guard band or a downlink sub-band, the sub-band type of the non-downlink sub-band is a guard band or an uplink sub-band, and the scenario where the first communication device is located is determined by the transmission power of the network device associated with the first communication device and / or the coverage area of the network device associated with the first communication device.
[0018] Implementing this method, the first reporting value is not only the reporting value corresponding to the CLI-RSSI measurement range where the second CLI-RSSI is located, but also the reporting value corresponding to the sub-band type of the non-upper sub-band or the non-downlink sub-band and / or the scenario where the first communication device is located, so that the CLI-RSSI can be reported more accurately.
[0019] In a possible implementation manner, determining the first reporting value according to the second CLI-RSSI includes:
[0020] Determining the first reporting value according to a first mapping relationship, the second CLI-RSSI, and at least one parameter associated with the first communication device, where the first mapping relationship includes the correspondence between the CLI-RSSI measurement range, at least one parameter, and the reporting value.
[0021] Implementing this method, the first mapping relationship includes the correspondence between the CLI-RSSI measurement range, at least one parameter, and the reporting value, so that the reporting value can more accurately reflect the second CLI-RSSI.
[0022] In a possible implementation manner, determining the first reporting value according to the second CLI-RSSI includes:
[0023] Determining a second mapping relationship corresponding to a first parameter associated with the first communication device, where the second mapping relationship includes the correspondence between the CLI-RSSI measurement range, at least one second parameter, and the reporting value, and the at least one parameter includes the first parameter and the at least one second parameter;
[0024] Determining the first reporting value according to the second mapping relationship, the second CLI-RSSI, and at least one second parameter associated with the first communication device.
[0025] Implementing this method, different mapping relationships can be set for different situations of the first parameter. When determining the reporting value, the second mapping relationship is determined according to the first parameter associated with the first communication device, and then the first reporting value is determined from the second mapping relationship, which can improve the efficiency of determining the reporting value.
[0026] In a possible implementation, the first parameter associated with the first communication device is the scenario where the first communication device is located, and the second parameter associated with the first communication device is the sub-band type of the non-upper sub-band or the non-lower sub-band; or,
[0027] the first parameter associated with the first communication device is the sub-band type of the non-upper sub-band or the non-lower sub-band, and the second parameter associated with the first communication device is the scenario where the first communication device is located.
[0028] Implementing this method can be to set different second mapping relationships for different scenarios. The second mapping relationship is the correspondence between the sub-band type, the measurement range, and the reported value, or to set different second mapping relationships for different sub-band types. The second mapping relationship is the correspondence between the scenario, the measurement range, and the reported value, so as to specifically set the correspondence between the measurement range and the reported value and improve the accuracy of the reported value.
[0029] In a possible implementation, the first mapping relationship or the second mapping relationship includes a first CLI-RSSI measurement range. The minimum boundary value of the first CLI-RSSI measurement range is less than a first threshold, and the maximum boundary value of the first CLI-RSSI measurement range is less than or equal to the first threshold.
[0030] Implementing this method, the first threshold can be the minimum boundary value of the existing correspondence between the measurement range and the reported value. For example, -100 dB. The reported value corresponding to less than -100 dB cannot accurately reflect the measured CLI-RSSI. In the embodiments of the present application, the first mapping relationship or the second mapping relationship includes a first CLI-RSSI measurement range. This first CLI-RSSI measurement range has a maximum and a minimum boundary value. The minimum boundary value is less than the first threshold, and the maximum boundary value is less than or equal to the first threshold. In other words, in the embodiments of the present application, the measurement range is extended to cover the smaller second CLI-RSSI in the embodiments of the present application, improving the reporting accuracy.
[0031] In a possible implementation, the reported value corresponding to the first CLI-RSSI measurement range is a reserved value.
[0032] Implementing this method, for the CLI-RSSI measurement range less than the first threshold, one CLI-RSSI measurement range corresponds to one reserved value, that is, the reserved value is used for indication, reducing the modification of the existing correspondence between the measurement range and the reported value.
[0033] In a possible implementation, the determining the first reported value according to the second CLI-RSSI includes:
[0034] Determine a third CLI-RSSI according to the second CLI-RSSI and the first offset value;
[0035] Determine the first reporting value according to the third CLI-RSSI, where the first reporting value is the reporting value corresponding to the CLI-RSSI measurement range in which the third CLI-RSSI is located.
[0036] Implementing this method can process the second CLI-RSSI based on the offset value, so that the third CLI-RSSI is within a predefined measurement range, improving the accuracy of reporting.
[0037] In a possible implementation, the first offset value is determined based on the sub-band type of the non-uplink sub-band or the non-downlink sub-band, and / or the scenario where the first communication device is located;
[0038] The sub-band type of the non-uplink sub-band is a guard band or a downlink sub-band, the sub-band type of the non-downlink sub-band is a guard band or an uplink sub-band, and the scenario where the first communication device is located is determined by the transmission power of the network device associated with the first communication device and / or the coverage area of the network device associated with the first communication device.
[0039] Implementing this method, different scenarios and / or different sub-band types correspond to different offset values, which can increase the probability that the processed third CLI-RSSI is within a predefined measurement range.
[0040] In a possible implementation, the resource unit is a resource block RB, and the value of X is greater than or equal to 6.
[0041] Implementing this method, the second CLI-RSSI can be the CLI-RSSI on more than 6 RBs. Compared with reporting the CLI-RSSI on 6 RBs in the prior art, the second CLI-RSSI in the embodiments of the present application can be larger, thereby increasing the probability that the second CLI-RSSI is within a predefined measurement range.
[0042] In a possible implementation, the value of X is determined based on the sub-band type of the non-uplink sub-band or the non-downlink sub-band, and / or the scenario where the first communication device is located;
[0043] The sub-band type of the non-uplink sub-band is a guard band or a downlink sub-band, the sub-band type of the non-downlink sub-band is a guard band or an uplink sub-band, and the scenario where the first communication device is located is determined by the transmission power of the network device associated with the first communication device and / or the coverage area of the network device associated with the first communication device.
[0044] Implementing this method, the value of X is specifically set based on the specific sub-band type and / or scenario, which can further increase the probability of making the second CLI-RSSI within the predefined measurement range.
[0045] In a possible implementation, the first transmission resource includes one or more sub-bands in the non-upper sub-band, or the first transmission resource includes one or more CLI-RSSI resources, and the measurement results of the one or more CLI-RSSI resources are reported through the same report.
[0046] Implementing this method, measuring one or more sub-bands in the non-upper sub-band together, that is, measuring in a more fine-grained manner, can make the measured CLI-RSSI more accurately reflect the interference intensity at each position of the frequency-domain resource. Measuring one or more CLI-RSSI resources reported through the same report together and obtaining a second CLI-RSSI reduces the reporting overhead.
[0047] In a possible implementation, the X resource units are all the resources included in the first transmission resource.
[0048] Implementing this method, the X resource units can be all the resource units in one or more sub-bands, or all the resource units in one or more CLI-RSSI resources, so that the second CLI-RSSI can be larger and the probability of making the second CLI-RSSI within the predefined measurement range can be increased.

There is no overlap between the frequency domain resource segment for uplink transmission and the one or more frequency domain resource segments for downlink transmission. In the embodiments of this application, the frequency domain resource segment for uplink transmission on the at least one symbol or time slot is referred to as an uplink sub-band, and the one or more frequency domain resource segments for downlink transmission on the at least one symbol or time slot are referred to as downlink sub-bands. The names of the uplink sub-band and the downlink sub-band are not limited and can also be other names.
[0113] Exemplarily, the at least one symbol or time slot can be a downlink time slot or a downlink symbol, or can be a flexible time slot or a flexible symbol.
[0114] The guardband in the embodiments of this application can be a frequency domain resource segment between adjacent uplink sub-bands and downlink sub-bands to reduce the transmission interference between the uplink sub-band and the downlink sub-band. The guardband can not be used for data transmission, but interference measurement can be performed on the guardband. The name of the guardband is not limited and can also be other names, such as a protection band, etc.
[0115] For example, as Figure 2a shown, two schematic diagrams of uplink sub-bands and downlink sub-bands are provided. There is a guardband between the uplink sub-band and the downlink sub-band shown in Figure 2a . In Figure 2a , the uplink sub-band is identified by "U", and the downlink sub-band is identified by "D". As in Figure 2a the first case described, there is one downlink sub-band and one uplink sub-band, and there is a guardband between the downlink sub-band and the uplink sub-band. The hatched filled area in Figure 2a is the guardband. As in Figure 2a the second case described, there are downlink sub-bands on both sides of the uplink sub-band. The above Figure 2a two cases are only examples, and the uplink sub-band and the downlink sub-band can also be other positional relationships, which are not limited in this application.
[0116] Through the uplink sub-band and the downlink sub-band, the base station can simultaneously perform uplink transmission and downlink transmission in one time slot or symbol. Compared with TDD, SBFD has more uplink resources and can increase the uplink coverage.
[0117] The sub-band full duplex in the embodiments of this application can be that the frequency domain resources are divided into different sub-bands on the base station side, and downlink transmission and uplink reception are simultaneously performed on different sub-bands respectively. For the terminal device, it can still support half duplex and can only perform downlink reception on the downlink sub-band or uplink transmission on the uplink sub-band in one time slot or one symbol.
[0118] 2. Cross link interference (CLI)
[0119] In SBFD, inter subband CLI (i.e., cross link interference between subbands) is introduced. Inter subband CLI is a newly introduced type of cross link interference in SBFD. Inter subband CLI can be divided into cross link interference between terminal devices and cross link interference between base stations.
[0120] Cross link interference between terminal devices is the interference of the transmitted signal of one terminal device on the uplink subband to the reception within the downlink subband of another terminal device. As Figure 2b shown, when the second terminal transmits a signal on the uplink subband, it will interfere with the reception of the first terminal on the downlink subband. Therefore, the first terminal can measure CLI-RSSI in the downlink subband or the guard band.
[0121] Cross link interference between base stations (which can also be referred to as cross link interference between network devices) is the interference of the transmitted signal of one base station on the downlink subband to the reception within the uplink subband of another base station. Therefore, the other base station can measure CLI-RSSI in the uplink subband or the guard band.
[0122] In the cross link interference scenario, the frequency domain positions of the transmitted signal and the measured signal for CLI-RSSI measurement are different, that is, the measured signal is the leakage of the transmitted signal at other frequency domain positions, so the intensity of the measured signal is relatively low. For example, the value of CLI-RSSI between base stations is in the range of -112 dBm to -90 dBm, and the value of CLI-RSSI between terminal devices is in the range of -150 dBm to -50 dBm. It can be understood that this range is only for example. The correspondence between the CLI-RSSI measurement range defined in the existing protocol and the reported value is shown in Table 1, which mainly defines the correspondence between each CLI-RSSI measurement range and the reported value in the range from -100 dBm to -25 dBm. For CLI-RSSI less than -100 dBm, 00 is reported, and accurate reporting cannot be achieved.
[0123] The reported value occupies 7 bits, that is, a 7-bit binary value is used to represent the reported value, and the valid values are 0 - 76, and the remaining values (i.e., 77 - 127) are reserved values. The specific reporting process can be that the terminal device measures CLI-RSSI, determines the CLI-RSSI value on 6 RB according to the measured CLI-RSSI, and after determining the CLI-RSSI value on 6 RB, determines the CLI-RSSI measurement range where the CLI-RSSI on 6 RB is located from the correspondence in Table 1, so as to determine the corresponding reported value.
[0124] Reported value CLI-RSSI measurement range Unit 00 CLI-RSSI < -100 dBm 01 -100 ≤ CLI-RSSI < -99 dBm 02 -99 ≤ CLI - RSSI < -98 dBm … … … 74 -27 ≤ CLI - RSSI < -26 dBm 75 -26 ≤ CLI - RSSI < -25 dBm 76 -25 ≤ CLI-RSSI dBm
[0125] Table 1
[0126] In the SBFD system, a large part of the CLI-RSSI between base stations or between terminal devices is much smaller than the minimum value -100 dBm of the reporting range in Table 1. Therefore, it is necessary to expand the reporting range.
[0127] Please refer to Figure 3a , which is a schematic diagram of a cross-link interference scenario provided by an embodiment of the present application. In Figure 3a , the terminal device 2 sends a signal on the uplink sub-band, and in Figure 3a , an example is given where the terminal device 2 sends a signal to the network device 2. The terminal device 1 receives a signal on the downlink sub-band, and in Figure 3a , an example is given where the terminal device 1 receives a signal sent by the network device 1. The signal sent by the terminal device 2 on the uplink sub-band will cause cross-link interference to the signal received by the terminal device 1 on the downlink sub-band. In the embodiment of the present application, the terminal device 1 can measure the CLI-RSSI on the transmission resources of the downlink sub-band, and the CLI-RSSI is the output power generated by the signal sent by the terminal device 2 on the uplink sub-band on the downlink sub-band. In this scenario, the first communication device in the embodiment of the present application may refer to the terminal device 1, and the second communication device may refer to the terminal device 2. The terminal device 1 obtains a reporting value according to the CLI-RSSI and reports it to the network device.
[0128] Please refer to Figure 3b , which is another schematic diagram of a cross-link interference scenario provided by an embodiment of the present application. In Figure 3b , the network device 1 sends a signal on the downlink sub-band, and in Figure 3b , an example is given where the network device 1 sends a signal to the terminal device 1. The network device 2 receives a signal on the uplink sub-band, and in Figure 3b , an example is given where the network device 2 receives the signal of the terminal device 2. The signal sent by the network device 1 on the downlink sub-band will cause cross-link interference to the signal received by the network device 2 on the uplink sub-band. In the embodiment of the present application, the network device 2 can measure the CLI-RSSI on the transmission resources of the uplink sub-band, and the CLI-RSSI is the output power generated by the signal sent by the network device 1 on the downlink sub-band on the uplink sub-band. In this scenario, the first communication device in the embodiment of the present application may refer to the network device 2, and the second communication device may refer to the network device 1. The network device 2 obtains a reporting value according to the measured CLI-RSSI and sends it to other network devices, and other network devices may include the network device 1.
[0129] It should be noted that the various technical solutions (or various embodiments) of the present application can be implemented independently or can be combined based on certain internal relationships. The present application does not make any limitations. And various terms and definitions between the various embodiments can be mutually referred to. In each embodiment of the present application, different implementation manners can also be combined or implemented independently.
[0130] Please refer to Figure 4 , which is a schematic flow chart of a CLI-RSSI reporting method provided by an embodiment of the present application. As Figure 4 shown, the CLI-RSSI reporting method of this embodiment includes but is not limited to the following steps:
[0131] 401. The first communication device measures the first CLI-RSSI on the first transmission resource.
[0132] Wherein, the first CLI-RSSI is the output power of the transmission signal of the second communication device on the second transmission resource on the first transmission resource. The second transmission resource is located in the uplink sub-band, and the first transmission resource is located in a non-uplink sub-band; or the second transmission resource is located in the downlink sub-band, and the first transmission resource is located in a non-downlink sub-band.
[0133] Exemplarily, the first communication device and the second communication device can both be network devices. The application scenario can be, for example, Figure 3b as shown. The second transmission resource can be located in the downlink sub-band, and the first transmission resource is located in a non-downlink sub-band. The non-downlink sub-band can include the uplink sub-band and / or the guard band. The corresponding measured first CLI-RSSI is the CLI-RSSI between network devices. For example, the non-downlink sub-band can only include the uplink sub-band, that is, the first transmission resource is located in the uplink sub-band. Another example is that the non-downlink sub-band can only include the guard band, that is, the first transmission resource is located in the guard band. Another example is that the non-downlink sub-band can include the uplink sub-band and the guard band, that is, a part of the first transmission resource is located in the uplink sub-band and a part is located in the guard band.
[0134] Exemplarily, the first communication device and the second communication device can both be terminal devices. The application scenario can be, for example, Figure 3a as shown. The second transmission resource can be located in the uplink sub-band, and the first transmission resource can be located in a non-uplink sub-band. The non-uplink sub-band can include the downlink sub-band and / or the guard band. The corresponding measured first CLI-RSSI is the CLI-RSSI between terminal devices. For example, the non-uplink sub-band can only include the downlink sub-band, that is, the first transmission resource is located in the downlink sub-band. Another example is that the non-uplink sub-band can only include the guard band, that is, the first transmission resource is located in the guard band. Another example is that the non-uplink sub-band can include the downlink sub-band and the guard band, that is, a part of the first transmission resource is located in the downlink sub-band and a part is located in the guard band.
[0135] In some implementations, the first transmission resource may be a measurement resource configured by a network device, or the first transmission resource may be a part of the measurement resources configured by the network device. For example, when the network device configures measurement resources and the first communication device divides the measurement resources into multiple time-frequency domain resources, one or more time-frequency domain resources can be measured together each time, and the one or more time-frequency domain resources measured together can be referred to as the first transmission resource.
[0136] Alternatively, the output power of the signal transmitted by the second communication device on the second transmission resource on the first transmission resource can be replaced with the signal strength of the signal transmitted by the second communication device on the second transmission resource on the first transmission resource.
[0137] 402. The first communication device determines a first reporting value according to the first CLI-RSSI.
[0138] Exemplarily, the first communication device may determine the CLI-RSSI measurement range where the first CLI-RSSI is located according to the mapping relationship, and determine the reporting value corresponding to the CLI-RSSI measurement range as the first reporting value, that is, the mapping relationship can define the corresponding relationship between the CLI-RSSI measurement range and the reporting value. Exemplarily, the mapping relationship may include the corresponding relationships between multiple CLI-RSSI measurement ranges and multiple reporting values, and one CLI-RSSI measurement range corresponds to one reporting value. The minimum boundary value in the mapping relationship can be determined according to the value range of CLI-RSSI between network devices or the value range of CLI-RSSI between terminal devices. For example, if the value range of CLI-RSSI between terminal devices is -150 dBm to -50 dBm, the minimum boundary value in the mapping relationship is less than or equal to -150 dBm. For example, the mapping relationship includes a CLI-RSSI measurement range of -150 dBm ≤ CLI-RSSI < Y, and the value of Y can be determined according to the size of a measurement range. For example, if a range is 1 dBm, the value of Y can be -149 dBm. Each measurement range is: -150 dBm ≤ CLI-RSSI < 149 dBm, -149 dBm ≤ CLI-RSSI < 148 dBm, -148 dBm ≤ CLI-RSSI < 147 dBm, and so on. The minimum boundary value in the mapping relationship can also be smaller than -150 dBm. For example, starting from -156 dBm, the size of a measurement range can be 1 dBm, or other values such as 0.5 dBm or 2 dBm, etc., which are not limited in this application.
[0139] Exemplarily, the first communication device may process the first CLI-RSSI. For example, the first CLI-RSSI may be converted into the second CLI-RSSI on X resource units, where X is a natural number. For example, the resource unit is (Resource block, RB). The first communication device determines the CLI-RSSI measurement range where the second CLI-RSSI is located according to the mapping relationship, and determines the reporting value corresponding to this CLI-RSSI measurement range as the first reporting value. The mapping relationship may include the corresponding relationships between multiple CLI-RSSI measurement ranges and multiple reporting values, and one CLI-RSSI measurement range corresponds to one reporting value. Similarly, the minimum boundary value in the mapping relationship may be determined according to the value range of the CLI-RSSI on X resource units between network devices, or the value range of the CLI-RSSI on X resource units between terminal devices.
[0140] Also, for example, the first CLI-RSSI or the above-mentioned second CLI-RSSI may be subjected to offset calculation. Offset calculation is performed based on an offset value and the first CLI-RSSI, or offset calculation is performed based on an offset value and the above-mentioned second CLI-RSSI, and the CLI-RSSI after offset calculation is obtained. The CLI-RSSI measurement range where the CLI-RSSI after offset calculation is located is determined according to the mapping relationship, and the reporting value corresponding to this CLI-RSSI measurement range is determined as the first reporting value.
[0141] 403. The first communication device sends the first reporting value to the third communication device. Correspondingly, the third communication device receives the first reporting value.
[0142] In some embodiments, the third communication device may be a different communication device from the second communication device. For example, if the first communication device and the second communication device are both terminal devices, the third communication device is a network device. In some embodiments, the third communication device may be the same communication device as the second communication device. For example, if the first communication device and the second communication device are both network devices, the first communication device may send the first reporting value to the second communication device.
[0143] 404. The third communication device determines the measurement range corresponding to the first reporting value.
[0144] The third communication device may determine the CLI-RSSI measurement range corresponding to the first reporting value. By obtaining the CLI-RSSI measurement range corresponding to the first reporting value, the third communication device can determine the cross-link interference intensity between the first communication device and the second communication device, which is convenient for the third communication device to perform subsequent scheduling. For example, it will not schedule the communication device with a relatively large cross-link interference intensity.
[0145] Please refer toFigure 5 , which is a schematic flowchart of another CLI-RSSI reporting method provided by an embodiment of this application. As Figure 5 shown, the CLI-RSSI reporting method of this embodiment includes but is not limited to the following steps:
[0146] 501. The first communication device measures the first CLI-RSSI on the first transmission resource.
[0147] Among them, the first CLI-RSSI is the output power of the transmission signal of the second communication device on the second transmission resource on the first transmission resource. The second transmission resource is located in the uplink sub-band, the first transmission resource is located in a non-uplink sub-band, or the second transmission resource is located in the downlink sub-band, and the first transmission resource is located in a non-downlink sub-band.
[0148] For step 501 of the embodiment of this application, please refer to Figure 4 the description of step 401 in the embodiment, which will not be elaborated here.
[0149] 502. The first communication device determines the second CLI-RSSI according to the first CLI-RSSI. The second CLI-RSSI is the CLI-RSSI on X resource units, and X is a natural number.
[0150] The first CLI-RSSI is the CLI-RSSI measured on the first transmission resource. The first transmission resource may include Z resource units. The resource unit may be a time-domain unit and / or a frequency-domain unit. For example, the resource unit may be an RB. The first CLI-RSSI on Z resource units can be converted into the second CLI-RSSI on X resource units, and the value of X may be a predefined value. The calculation method may be that the CLI-RSSI on each resource unit can be calculated according to the first CLI-RSSI, and then the CLI-RSSI on each resource unit is multiplied by the value of X, so as to convert to the CLI-RSSI on X resource units. For example, X resource units may be 6 RBs, that is, it is converted into the CLI-RSSI on 6 RBs. In some embodiments, the value of X may also be greater than 6.
[0151] 503. The first communication device determines the first reporting value according to the second CLI-RSSI.
[0152] In one implementation, the first communication device may determine the CLI-RSSI measurement range where the second CLI-RSSI is located, and thus determine the reporting value corresponding to this CLI-RSSI measurement range as the first reporting value.
[0153] Another implementation method is to perform an offset calculation on the second CLI-RSSI based on the offset value, so as to determine the CLI-RSSI after the offset calculation, and determine the reporting value corresponding to the CLI-RSSI measurement range where the CLI-RSSI after the offset calculation is located as the first reporting value.
[0154] 504. The first communication device sends the first reporting value to the third communication device. Correspondingly, the third communication device receives the first reporting value.
[0155] 505. The third communication device determines the measurement range corresponding to the first reporting value.
[0156] For steps 504 and 505 in the embodiments of this application, please refer to Figure 4 steps 403 and 404, which will not be elaborated here.
[0157] In the above Figure 4 and Figure 5 In the method embodiments shown, the first transmission resource for measurement is in a different frequency domain position from the second transmission resource where the signal is sent. For example, if the second transmission resource is an uplink sub-band, the first transmission resource is located in a non-uplink sub-band; or if the second transmission resource is located in a downlink sub-band, the first transmission resource is located in a non-downlink sub-band. Therefore, the intensity of the measured signal is relatively low. In the existing protocol, Table 1 mainly defines the CLI-RSSI between -100 dBm and -25 dBm. For the measurement range less than -100 dBm, the reporting value 00 is used, that is, the CLI-RSSI less than -100 dBm cannot be accurately reported. However, a large part of the CLI-RSSI values between terminal devices or between network devices in the embodiments of this application are much less than the minimum boundary value -100 dBm of the mapping relationship shown in Table 1. The embodiments of this application propose the following solutions:
[0158] Case 1: It is necessary to update the mapping relationship shown in Table 1 so that it can cover all possible values of the CLI-RSSI between the first communication device and the second communication device in the embodiments of this application.
[0159] The minimum boundary value of the updated mapping relationship is less than or equal to the first threshold, that is, the updated mapping relationship includes the reported value corresponding to the first CLI-RSSI measurement range. The first CLI-RSSI measurement range includes a minimum boundary value and a maximum boundary value. The minimum boundary value is less than the first threshold, and the maximum boundary value is less than or equal to the first threshold. The first threshold may be, for example, the minimum boundary value included in the mapping relationship in the existing protocol, such as -100 dBm. The first CLI-RSSI measurement range may be any one of the multiple CLI-RSSI measurement ranges in the updated mapping relationship where the CLI-RSSI is less than the first threshold. In the embodiments of the present application, the mapping relationship shown in Table 1 is extended to include multiple CLI-RSSI measurement ranges less than -100 dBm.
[0160] The minimum boundary value of the redefined mapping relationship can be determined according to the value range of the CLI-RSSI between the first communication device and the second communication device. For example, if the value range of the CLI-RSSI between the first communication device and the second communication device is -150 dBm to -50 dBm, the minimum boundary value of the redefined mapping relationship can be -150 dBm or less than -150 dBm. The size of each CLI-RSSI measurement range can be the same or different, which is not limited in the present application. For example, if each CLI-RSSI measurement range is 1 dBm and the minimum boundary value can be -150 dBm, the reported values corresponding to -150 dBm ≤ CLI-RSSI < -149 dBm, -149 dBm ≤ CLI-RSSI < -148 dBm, etc. can be defined respectively, and so on.
[0161] The corresponding relationship between the CLI-RSSI measurement range, at least one parameter, and the reported value can be predefined. Among them, the at least one parameter may include the subband type and / or the scenario. If the first transmission resource is in a non-uplink subband, the subband type of the non-uplink subband may include a guard band and a non-guard band, or a downlink subband and a non-downlink subband, or a guard band and a downlink subband. If the first transmission resource is in a non-downlink subband, the subband type of the non-downlink subband may include a guard band and a non-guard band, or an uplink subband and a non-uplink subband, or a guard band and an uplink subband. The scenario can be determined by the transmission power of the network device associated with the communication device performing the measurement and / or the coverage area of the associated network device. For example, the scenario may include at least one of the following scenarios: indoor scenario, urban macro coverage scenario (Urban Macro), suburban macro coverage scenario, dense urban coverage, high-speed railway coverage.
[0162] In one implementation, the correspondence between the CLI-RSSI measurement range, sub-band type, and reporting value can be predefined, where one CLI-RSSI measurement range and one sub-band type correspond to one reporting value. In another implementation, the correspondence between the CLI-RSSI measurement range, scenario, and reporting value can be predefined, where one CLI-RSSI measurement range and one scenario correspond to one reporting value. In yet another implementation, the correspondence between the CLI-RSSI measurement range, sub-band type, scenario, and reporting value can be predefined, where one CLI-RSSI measurement range, one sub-band type, and one scenario correspond to one reporting value.
[0163] The first reporting value determined by the first communication device can be the reporting value corresponding to the CLI-RSSI measurement range where the second CLI-RSSI is located (for the specific method of obtaining the second CLI-RSSI, please refer to the description of step 502 in the Figure 5 embodiment and will not be elaborated here), and the at least one parameter associated with the first communication device. The at least one parameter associated with the first communication device includes the sub-band type of the non-upper or non-lower sub-band where the first transmission resource is located, and / or the scenario where the first communication device is located.
[0164] The correspondence between the CLI-RSSI measurement range, at least one parameter, and reporting value can be predefined through one or more mapping relationships. Examples are described below in Method 1 and Method 2:
[0165] Method 1: The correspondence between the CLI-RSSI measurement range, at least one parameter, and reporting value can be defined through one mapping relationship (such as the first mapping relationship).
[0166] The first mapping relationship includes the correspondence between the CLI-RSSI measurement range, at least one parameter, and reporting value. The first mapping relationship can be a table, that is, a table includes the correspondence between the CLI-RSSI measurement range, at least one parameter, and reporting value. The at least one parameter includes the sub-band type and / or scenario. The sizes of the CLI-RSSI measurement ranges can be the same or different, and this application does not make a limitation. In some implementations, the size of the CLI-RSSI measurement range can be determined according to the scenario and / or sub-band type. For example, the sizes of the CLI-RSSI measurement ranges in the same scenario and / or the same sub-band type can be the same, and the sizes of the CLI-RSSI measurement ranges in different scenarios and / or different sub-band types can be different. For example, the CLI-RSSI value range measured for an indoor scenario is relatively small, such as -112 dBm to -100 dBm, then the size of one CLI-RSSI measurement range can be even smaller, such as 0.5 dBm as the size of one CLI-RSSI measurement range, so as to make the reporting more accurate.
[0167] The first communication device determines a corresponding first reporting value from the first mapping relationship according to the at least one parameter associated with the first communication device. In Table 2 below, taking the at least one parameter including scenario and sub-band type as an example, the first mapping relationship (i.e., Table 2) includes the corresponding relationship between scenario, sub-band type, CLI-RSSI measurement range and reporting value. In Table 2, taking the scenario including indoor scenario and urban macro coverage scenario as an example. One scenario, one sub-band type and one CLI-RSSI measurement range correspond to one reporting value. In Table 2, taking the reporting values as 00, 01, 02 as an example, and each measurement range is only for example.
[0168]
[0169] Table 2
[0170] In some possible implementation manners, in the first mapping relationship of Mode 1, if the minimum boundary value in a measurement range is less than the first threshold and the maximum boundary value is less than or equal to the first threshold, for example, the first threshold is -100 dBm, the reporting value corresponding to this measurement range can be a reserved value, for example, a value in the range of 77 to 127. For the CLI-RSSI measurement range between -100 dBm and -25 dBm, the corresponding relationship between the CLI-RSSI measurement range and the reporting value shown in Table 1 can continue to be used.
[0171] Mode 2, the corresponding relationship between the CLI-RSSI measurement range, the at least one parameter and the reporting value can be defined through multiple mapping relationships.
[0172] The at least one parameter includes a first parameter and at least one second parameter, and different first parameters correspond to different mapping relationships. The mapping relationship corresponding to the first parameter includes the corresponding relationship between at least one second parameter, CLI-RSSI measurement range and reporting value. Among them, different first parameters corresponding to different mapping relationships can be understood as different first parameters corresponding to different tables. The sizes of each CLI-RSSI measurement range can be the same or different, and this application does not make a limitation. In some implementation manners, the size of the CLI-RSSI measurement range can be determined according to the scenario and / or sub-band type. For example, the sizes of the CLI-RSSI measurement ranges in the same scenario and / or the same sub-band type can be the same, and the sizes of the CLI-RSSI measurement ranges in different scenarios and / or different sub-band types can be different.
[0173] Exemplarily, the first parameter may be a scenario, and the second parameter may be a sub-band type. Different mapping relationships can be defined for different scenarios, one scenario corresponding to one mapping relationship, which can also be understood as one scenario corresponding to one table. The mapping relationship corresponding to one scenario includes the corresponding relationship between the sub-band type, the CLI-RSSI measurement range, and the reporting value. For example, Table 3 may be the mapping relationship corresponding to the indoor scenario, and this mapping relationship includes the corresponding relationship between the sub-band type, the CLI-RSSI measurement range, and the reporting value. It can be understood that mapping relationships corresponding to other scenarios can also be defined, such as defining the mapping relationship corresponding to the urban macro coverage scenario, which is not limited in this application.
[0174] The first communication device determines the scenario associated with the first communication device, so as to determine the second mapping relationship corresponding to the scenario associated with the first communication device. Further, according to the sub-band type associated with the first communication device (i.e., the sub-band type of the non-upper or non-lower sub-band where the first transmission resource is located) and the second CLI-RSSI, the first reporting value is determined from the second mapping relationship, and the first reporting value is the reporting value corresponding to the CLI-RSSI measurement range where the sub-band type and the second CLI-RSSI associated with the first communication device are located.
[0175] Reported value Guard band Non-guard band 00 CLI-RSSI < -112 CLI-RSSI < -125 01 -112 ≤ CLI - RSSI < -111.5 -125 ≤ CLI-RSSI < -124.5 02 -111.5 ≤ CLI - RSSI < -110 -124.5 ≤ CLI - RSSI < -124
[0176] Table 3
[0177] Exemplarily, the first parameter may be a sub-band type, and the second parameter may be a scenario. Different mapping relationships can be defined for different sub-band types, one sub-band type corresponding to one mapping relationship, which can also be understood as one sub-band type corresponding to one table. The mapping relationship corresponding to one sub-band type includes the corresponding relationship between the scenario, the CLI-RSSI measurement range, and the reporting value, and one scenario and one CLI-RSSI measurement range correspond to one reporting value.
[0178] The first communication device determines the sub-band type associated with the first communication device (i.e., the sub-band type of the non-upper or non-lower sub-band where the first transmission resource is located), and determines the second mapping relationship corresponding to the sub-band type. Further, according to the scenario associated with the first communication device and the second CLI-RSSI, the first reporting value is determined from the second mapping relationship, and the first reporting value is the reporting value corresponding to the CLI-RSSI measurement range where the scenario and the second CLI-RSSI associated with the first communication device are located.
[0179] In some possible implementations, among the mapping relationships of Mode 2, if the minimum boundary value in a measurement range is less than the first threshold and the maximum boundary value is less than or equal to the first threshold. For example, if the first threshold is -100 dBm, the reported value corresponding to this measurement range can be a reserved value, for example, one of the values from 77 to 127. For the CLI-RSSI measurement range between -100 dBm and -25 dBm, the corresponding relationship between the CLI-RSSI measurement range and the reported value shown in Table 1 can continue to be used.
[0180] In Modes 1 and 2, not only is the CLI-RSSI measurement range of the mapping relationship shown in Table 1 extended to the reported values corresponding to multiple CLI-RSSI measurement ranges less than the first threshold, but also in Modes 1 and 2, the CLI-RSSI measurement range is determined separately according to the scenario and / or sub-band type, which is convenient for flexibly determining the size of the CLI-RSSI measurement range corresponding to various scenarios and / or various sub-band types.
[0181] For Case 2, the mapping relationship shown in Table 1 may not be updated, and the following method can be used for reporting or measurement.
[0182] It should be noted that when the following various methods are specifically implemented, they can also be used in combination with the updated mapping relationship in Case 1, that is, it is not limited that the following methods must be used in the scenario where the mapping relationship in Table 1 is not updated.
[0183] In the following various methods, the second CLI-RSSI refers to the CLI-RSSI on X resource units, and the specific acquisition method Figure 5 The description of step 502 in the embodiment will not be repeated below.
[0184] Mode 1: Determine the third CLI-RSSI according to the second CLI-RSSI and the first offset value, and then determine the reported value corresponding to the CLI-RSSI measurement range where the third CLI-RSSI is located as the first reported value.
[0185] Exemplarily, the third CLI-RSSI is greater than the second CLI-RSSI. For example, if the second CLI-RSSI is -120 dBm and the first offset value is 30 dBm, then according to the second CLI-RSSI and the first offset value, the calculated third CLI-RSSI can be -120 dBm + 30 dBm = -90 dBm.
[0186] Find the CLI-RSSI measurement range where the third CLI-RSSI is located in the mapping relationship, and then use the reporting value corresponding to the CLI-RSSI measurement range where the third CLI-RSSI is located as the first reporting value. The mapping relationship includes the corresponding relationship between the CLI-RSSI measurement range and the reporting value, and one CLI-RSSI measurement range corresponds to one reporting value. Exemplarily, the mapping relationship can be shown in Table 1. Due to the offset calculation, the probability that the third CLI-RSSI falls within the CLI-RSSI measurement range of -100 dBm to -25 dBm can be increased, so the mapping relationship shown in Table 1 can continue to be used.
[0187] In some implementation manners, the corresponding relationship between the sub-band type and / or scenario and the offset value can be predefined or network-configured. One sub-band type and / or one scenario corresponds to one offset value. Different scenarios and / or different sub-band types correspond to different offset values. As shown in Table 4, it is a schematic diagram of the corresponding relationship between the scenario, sub-band type and offset value. It can be understood that the corresponding relationship between the sub-band type and the offset value can also be predefined or network-configured, one sub-band type corresponds to one offset value, or the corresponding relationship between the scenario and the offset value can also be predefined or network-configured, one scenario corresponds to one offset value, and so on. This application does not make limitations.
[0188] When the first communication device determines the first offset value, it needs to first determine the scenario where the first communication device is located and / or the sub-band type corresponding to the first transmission resource, so as to determine the first offset value according to the scenario where the first communication device is located and / or the sub-band type. Use the first offset value to perform offset calculation on the second CLI-RSSI obtained by conversion to obtain the third CLI-RSSI, determine the reporting value corresponding to the CLI-RSSI measurement range where the third CLI-RSSI is located as the first reporting value, and send the first reporting value to the third communication device. After receiving the first reporting value, the third communication device can determine the CLI-RSSI measurement range corresponding to the first reporting value. Optionally, the third communication device can also determine the corresponding first offset value according to the scenario where the first communication device is located and / or the sub-band type, so as to correct the CLI-RSSI measurement range corresponding to the first reporting value based on the corresponding first offset value. For example, subtract the first offset value from the minimum boundary value and the maximum boundary value of the CLI-RSSI measurement range corresponding to the first reporting value respectively to determine an updated CLI-RSSI measurement range.
[0189]
[0190] Table 4
[0191] Method 2, the second CLI-RSSI is the CLI-RSSI on X RBs, and the value of X is greater than or equal to 6.
[0192] In the mapping relationship of Table 1, the CLI-RSSI measurement value in the CLI-RSSI measurement range is defined based on 6 RBs, that is, the reporting is based on the CLI-RSSI on 6 RBs. In this Method 2, when changing the number of RBs for reporting CLI-RSSI and increasing the number of RBs, the second RSSI value will also increase. Correspondingly, the probability that the second RSSI falls within the range of -100 dBm to -25 dBm can be increased.
[0193] In this method, the value of X can be predefined or configured by a network device, which is not limited in this application. The value of X can also be determined based on the subband type and / or scenario. For example, one subband type corresponds to one value of X, and different subband types correspond to different values of X; or one scenario corresponds to one value of X, and different scenarios correspond to different values of X; or one subband type and one scenario correspond to one value of X, etc., which is not limited in this application.
[0194] Method 3, the first transmission resource includes one or more subbands in the non-uplink subband or non-downlink subband, and the second CLI-RSSI can be the CLI-RSSI on all resources on the one or more subbands in the first transmission resource, that is, X resource units are all resources on the one or more subbands.
[0195] The subband in the embodiments of this application refers to a segment of frequency domain resource in the non-uplink subband or non-downlink subband. For example, the non-uplink subband or non-downlink subband is further divided into one or more segments of frequency domain resources in the frequency domain, and the segments of frequency domain resources do not overlap with each other. A segment of frequency domain resource obtained by division is called a subband. The number of RBs in each subband can be the same or different. In some implementation manners, the uplink subband or downlink subband can also be further divided into one or more subbands. In some implementation manners, the guard band can also be divided into subbands, which is not limited in this application.
[0196] Exemplarily, as Figure 6a and Figure 6b shown, there are two schematic diagrams of subband division. In Figure 6a and Figure 6b taking the division of subbands in the non-uplink subband as an example. As Figure 6a shown, the non-uplink subband is evenly divided, that is, the number of RBs included in the frequency domain resource of each subband is the same. As Figure 6bAs shown, the non-upper subbands are unevenly divided, that is, the subbands closer to the upper subband have fewer resource blocks (RBs), and the subbands farther from the upper subband have more RBs. Among them, each subband in the non-upper subbands can be located in the downlink subbands and / or the guard bands. Each subband in the non-downlink subbands can be located in the upper subbands and / or the guard bands. Further divide the non-upper subbands or non-downlink subbands, and perform measurements on one or more subbands, so as to obtain the CLI-RSSI at each frequency domain position, thereby accurately reflecting the cross-link interference intensity at each frequency domain position.
[0197] The first transmission resource includes one or more subbands in the non-upper subbands or non-downlink subbands, that is, the first communication device can measure one or more subbands together each time to obtain the first CLI-RSSI on the one or more subbands. The one or more subbands can be associated subbands configured by the network. In some implementation manners, when the subbands are configured in a symmetric configuration, since the interference situations on both sides of the upper subband are similar, multiple subbands at equal distances from the upper subband can be associated. For example, as Figure 6a and Figure 6b shown, subband 4 and subband 5 can be associated and measured together. In some implementation manners, the multiple subbands can also be on the same side of the upper subband, and the present application does not limit the positions of the subbands.
[0198] In some implementation manners, the one or more subbands included in the first transmission resource can be part of the measurement resources configured by the network. For example, if the measurement resources configured by the network include 8 subbands, the measurement resources can be divided into 4 blocks of transmission resources, and each block of transmission resources includes 2 subbands, that is, two subbands are measured together. For example, Figure 6a and Figure 6b shown, subband 4 and subband 5 correspond to the same block of transmission resources, subband 3 and subband 6 correspond to the same block of transmission resources, subband 2 and subband 7 correspond to the same block of transmission resources, and subband 1 and subband 8 correspond to the same block of transmission resources. Each time 2 subbands correspond to the same block of transmission resources, and the first transmission resource can be any one of the 4 blocks of transmission resources.
[0199] The first communication device can use the first CLI-RSSI as the second CLI-RSSI on X resource units, that is, the X resource units are all the resources on the one or more subbands mentioned above, and then determine the first reporting value according to the second CLI-RSSI. In some implementation manners, the second CLI-RSSI can also be the CLI-RSSI on X RBs obtained by conversion, that is, convert the first CLI-RSSI to the CLI-RSSI on X RBs. For example, the value of X is an integer greater than 6 and can be a predefined value.
[0200] Mode 4. The first transmission resource includes one or more CLI-RSSI resources in a non-UL subband or a non-DL subband. The measurement results of the one or more CLI-RSSI resources are reported through the same report, and the reported second CLI-RSSI may be the CLI-RSSI on the one or more CLI-RSSI resources.
[0201] The one or more CLI-RSSI resources may be measurement resources configured by a network device for measuring CLI-RSSI. The one or more CLI-RSSI resources correspond to the same report ID, that is, the measurement results of the one or more CLI-RSSI resources are reported through the same report. In the embodiment of the present application, the first transmission resource includes the one or more CLI-RSSI resources, and the second CLI-RSSI may be the CLI-RSSI on the one or more CLI-RSSI resources, which can increase the probability that the second CLI-RSSI falls within the range of -100 dBm to -25 dBm, so that the reported value corresponding to the CLI-RSSI measurement range where the second CLI-RSSI is located can be found through the mapping relationship shown in Table 1.
[0202] In some implementation manners, in this mode 4, the second CLI-RSSI may also be the CLI-RSSI on X RBs obtained by conversion, that is, the first CLI-RSSI measured on the one or more CLI-RSSI resources is converted into the CLI-RSSI on X RBs. For example, the value of X is an integer greater than 6 and may be a predefined value.
[0203] It should be noted that the above manners in Case 1 and Case 2 can be used alone or in combination. For example, the manner 1 in Case 1 can be combined with any one of the manners 1 to 4 in Case 2, and the manner 2 in Case 1 can also be combined with any one of the manners 1 to 4 in Case 2. For example, a new mapping relationship can be used in Case 1, and at the same time, the manner 4 in Case 2 can be used for measurement.

[0253] Regarding Figure 8 For the specific embodiment description of Figure 4 or Figure 5 Please refer to the description of the embodiments, and details are not described herein again.
[0254] Please refer to Figure 9 , Figure 9 which is a schematic structural diagram of a communication device provided by an embodiment of the present application, and is used to implement the function of the first communication device in the above Figure 4 or Figure 5 , or is used to implement the function of the third communication device in the above Figure 4 or Figure 5 . The communication device 300 may be a terminal device or a device for a terminal device. The device for a terminal device may be a chip system or a chip in the terminal device. The communication device may also be a network device or a device for a network device. The device for a network device may be a chip system or a chip in the network device. Among them, the chip system may be composed of chips, or may include chips and other discrete devices.
[0255] The communication device 300 includes at least one processor 320, which is used to implement the data processing function of the first communication device or the third communication device in the method provided by the embodiment of the present application. The communication device 300 may further include a communication interface 310, which is used to implement the transceiver operation of the first communication device or the third communication device in the method provided by the embodiment of the present application. In the embodiment of the present application, the processor 320 may be a central processing unit (CPU), and the processor may also be other general-purpose processors, digital signal processors (DSPs), application specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc. In the embodiment of the present application, the communication interface 310 may be a transceiver, a circuit, a bus, a module, or other types of communication interfaces, and is used to communicate with other devices through a transmission medium. For example, the communication interface 310 is used for the communication device 300 to communicate with other devices. The processor 320 uses the communication interface 310 to transmit and receive data, and is used to implement the method described in the above method embodiment Figure 4 or Figure 5 .
[0256] The communication device 300 may further include at least one memory 330 for storing program instructions and / or data. The memory 330 is coupled to the processor 320.

[0257] After the communication device 300 is powered on, the processor 320 may read the software program in the memory 330, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be wirelessly transmitted, after the processor 320 performs baseband processing on the data to be transmitted, it outputs a baseband signal to the radio frequency circuit ( Figure 9 not shown), and the radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device 300, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 320. The processor 320 converts the baseband signal into data and processes the data.
[0258] In another implementation, the radio frequency circuit and the antenna may be provided independently of the processor 320 that performs baseband processing. For example, in a distributed scenario, the radio frequency circuit and the antenna may be independent of the device and arranged in a remote manner.

The bus may be divided into an address bus, a data bus, a control bus, etc. For the sake of convenience of representation, Figure 9 only a thick line is used to represent it in
[0260] When the communication device 300 is specifically a terminal device, for example, when the communication device 300 is specifically a chip or a chip system, the baseband signal may be output or received by the communication interface 310. When the communication device 300 is specifically a terminal device, the radio frequency signal may be output or received by the communication interface 310.

Alternatively, at least some modules may be implemented in the form of software programs, and the software programs run on a processor integrated within the terminal device, and the remaining (if any) part of the modules may be implemented in the form of hardware such as circuits.
