Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a reporting method and a communication device. Background Art

[0002] In traditional time division duplex (TDD) systems, uplink and downlink communications share the same frequency domain resources, but they occupy different time domain resources. For example, a base station can send downlink data in a downlink timeslot and cannot receive uplink data in a downlink timeslot. Another example is a base station can receive uplink data in an uplink timeslot and cannot send downlink data in an uplink timeslot. However, because downlink timeslots account for a large proportion of traditional TDD systems, uplink resources are insufficient, increasing uplink service scheduling latency. Therefore, subband full duplex (SBFD) is introduced. Specifically, a new type of timeslot, the SBFD timeslot, is introduced into TDD systems. For a base station, an SBFD timeslot can be configured with both uplink and downlink subbands. Therefore, in an SBFD timeslot, the base station can receive uplink data in the uplink subband and send downlink data in the downlink subband. However, with the introduction of SBFD timeslots, traditional channel state information (CSI) reporting is no longer applicable. Summary of the Invention

[0003] The embodiments of the present application provide a reporting method and a communication device, which can achieve flexible and accurate reporting of CSI after the introduction of SBFD.

[0004] In a first aspect, an embodiment of the present application provides a reporting method, the method comprising:

[0005] Sending first CSI for an SBFD time unit and / or first CSI for a non-SBFD time unit, where the first CSI for the SBFD time unit includes at least one CSI measurement result obtained based on the first resource measurement, and the first CSI for the non-SBFD time unit includes at least one measurement result obtained based on the second resource measurement;

[0006] The time unit occupied by the first resource in the time domain is an SBFD time unit, the frequency domain resource occupied by the first resource in the frequency domain is a downlink subband corresponding to the SBFD time unit, the time unit occupied by the second resource in the time domain is a non-SBFD time unit, and the frequency domain resource occupied by the second resource in the frequency domain is the frequency domain resource corresponding to the non-SBFD time unit. The frequency domain resource corresponding to the non-SBFD time unit is used for downlink transmission.

[0007] By implementing the method of the first aspect and introducing SBFD, at least one of the CSI of the SBFD time unit and the CSI of the non-SBFD time unit can be reported, and the reporting can be performed according to specific needs. The flexibility of CSI reporting is relatively good. Compared with the method of reporting all time units indiscriminately, the present application distinguishes between reporting the CSI of the SBFD time unit and the CSI of the non-SBFD time unit, which allows the network device to more accurately obtain the channel state information of the resources on the two types of time units, thereby improving the accuracy of resource scheduling.

[0008] In a possible implementation, the sending of the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit includes:

[0009] A CSI report is sent, where the CSI report includes a first part, where the first part includes the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit.

[0010] By implementing this approach, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit can be carried in the first part of the same CSI report, which helps to improve the reliability of important data transmission.

[0011] In a possible implementation, the first part includes the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit, including:

[0012] The first part includes at least one field, each field including a CSI measurement result obtained based on the first resource measurement and included in the first CSI for the SBFD time unit, and a CSI measurement result obtained based on the second resource measurement and included in the first CSI for the non-SBFD time unit.

[0013] In this implementation, a field in the first part includes a measurement result in the first CSI for the SBFD time unit and a measurement result in the first CSI for the non-SBFD time unit. This implementation does not require changing the number of fields included in the first part.

[0014] In a possible implementation, the first part includes the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit, including:

[0015] The first part includes a first domain set and a second domain set; the first domain set includes at least one first domain, each first domain includes a CSI measurement result obtained by measuring the first resource and included in the first CSI for the SBFD time unit; the second domain set includes at least one second domain, each second domain includes a CSI measurement result obtained by measuring the second resource and included in the first CSI for the non-SBFD time unit;

[0016] The first domain set is located before the second domain set in the first part; or the second domain set is located before the first domain set in the first part.

[0017] By implementing this approach, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit are placed in the first part through two different field sets, which can facilitate obtaining the first CSI of different types of time units from the CSI report.

[0018] In a possible implementation, the CSI report further includes a second part, where the second part includes a second CSI for an SBFD time unit and / or a second CSI for a non-SBFD time unit; the second CSI for the SBFD time unit includes at least one CSI measurement result obtained based on the first resource measurement, and the second CSI for the non-SBFD time unit includes at least one CSI measurement result obtained based on the second resource measurement;

[0019] The priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit, and the priority of the first CSI for the non-SBFD time unit is higher than the priority of the second CSI for the non-SBFD time unit.

[0020] When this method is implemented, the second CSI for the SBFD time unit and / or the second CSI for the non-SBFD time unit is carried in the second part of the CSI report. Since the content carried in the second part of the CSI report is less important than the content of the first part of the CSI report, that is, has a lower priority, the content of the second part of the CSI report may not be transmitted when transmission resources are insufficient, thereby ensuring the transmission of high-priority content.

[0021] In a possible implementation, the sending the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit includes:

[0022] Sending a CSI report, where the CSI report includes a first part and a second part;

[0023] The first part includes the first CSI for the SBFD time unit, and the second part includes the first CSI for the non-SBFD time unit; or, the first part includes the first CSI for the non-SBFD time unit, and the second part includes the first CSI for the SBFD time unit.

[0024] By implementing this method, the first CSI for the SBFD time unit or the first CSI for the non-SBFD time unit is placed in the second part, and the size of the first part of the CSI report is controlled to avoid the inability to transmit all transmission resources due to excessive content in the first part, thereby ensuring the reliability of the transmission of important content carried in the first part.

[0025] In a possible implementation, the second part further includes a second CSI for an SBFD time unit and / or a second CSI for a non-SBFD time unit;

[0026] The second CSI for the SBFD time unit includes at least one CSI measurement result obtained based on the first resource measurement, and the second CSI for the non-SBFD time unit includes at least one measurement result obtained based on the second resource measurement;

[0027] The priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit, and the priority of the first CSI for the non-SBFD time unit is higher than the priority of the second CSI for the non-SBFD time unit.

[0028] When this method is implemented, the second part of the CSI report may include, in addition to the first CSI of one type of time unit, the second CSI of two types of time units. However, the first CSI of the two types of time units has the highest priority, that is, the first CSI carried in the second part has the lowest discarding priority, thereby ensuring the transmission of the first CSI and improving the reliability of the first CSI transmission.

[0029] In a possible implementation, if the first part includes the first CSI for the first time unit, and the second part includes the first CSI for the second time unit; then

[0030] The priority of the first CSI for the first time unit is higher than the priority of the first CSI for the second time unit, the priority of the first CSI for the second time unit is higher than the priority of the second CSI for the first time unit, and the priority of the first CSI for the second time unit is higher than the priority of the second CSI for the second time unit;

[0031] The first time unit is an SBFD time unit, and the second time unit is a non-SBFD time unit; or the first time unit is a non-SBFD time unit, and the second time unit is an SBFD time unit.

[0032] When this method is implemented and the first CSI of the second time unit is placed in the second part, the priority of the first CSI of the second time unit is the highest, that is, the discarding priority of the first CSI carried in the second part is the lowest, thereby ensuring the transmission reliability of the first CSI of the second time unit.

[0033] In a possible implementation, when N CSI reports are sent, and the N CSI reports include the CSI report, the order of discarding priority of the measurement results included in the second part of the N CSI reports from low to high is:

[0034] The wideband CSI for the first time unit included in all CSI reports in the N CSI reports, the wideband CSI for the second time unit included in all CSI reports in the N CSI reports, the subband CSI included in CSI Report 1 in the N CSI reports, the subband CSI included in CSI Report 2 in the N CSI reports, up to the subband CSI included in CSI Report N in the N CSI reports;

[0035] The order of discarding priority of the subband CSI included in the CSI report i from low to high is:

[0036] Even subband CSI for the first time unit, odd subband CSI for the first time unit, even subband CSI for the second time unit, odd subband CSI for the second time unit; the value of i ranges from 1 to N, where N is a positive integer greater than or equal to 1;

[0037] The first time unit is an SBFD time unit, and the second time unit is a non-SBFD time unit; or the first time unit is a non-SBFD time unit, and the second time unit is an SBFD time unit.

[0038] The higher the discarding priority, the higher the discarding priority. For example, when transmission resources are insufficient, the content with the higher discarding priority can be discarded first in descending order of discarding priority.

[0039] When this approach is implemented, when the CSI report includes CSI of two types of time units, the discarding priority order of the measurement results included in the second part of N CSI reports is redefined to ensure the transmission of high-priority information.

[0040] In a possible implementation, when N CSI reports are sent, and the N CSI reports include the CSI report, the order of discarding priority of the measurement results included in the second part of the N CSI reports from low to high is:

[0041] The wideband CSI for the SBFD time unit and the non-SBFD time unit included in all CSI reports in the N CSI reports, the subband CSI included in CSI report 1 in the N CSI reports, the subband CSI included in CSI report 2 in the N CSI reports, up to the subband CSI included in CSI report N in the N CSI reports;

[0042] The order of discarding priority of the subband CSI included in the CSI report i from low to high is:

[0043] Even subband CSI for SBFD time units and non-SBFD time units, odd subband CSI for SBFD time units and non-SBFD time units; the value of i ranges from 1 to N, where N is a positive integer greater than or equal to 1.

[0044] When this approach is implemented, when the CSI report includes CSI of two types of time units, the discarding priority order of the measurement results included in the second part of N CSI reports is redefined to ensure the transmission of high-priority information.

[0045] In a possible implementation, the method further includes:

[0046] Obtaining a first priority value according to a measurement result based on the first resource;

[0047] Obtaining a second priority value according to a measurement result based on the second resource;

[0048] Determine a priority value of the CSI report according to the first priority value and the second priority value.

[0049] By implementing this approach, priority values can be calculated based on the first resource corresponding to the SBFD time unit and the second resource corresponding to the non-SBFD time unit to obtain the priority of the CSI report, while taking into account the priority of CSI on both types of time units.

[0050] In a possible implementation manner, the priority value of the CSI report is a larger value between the first priority value and the second priority value; or,

[0051] The priority value of the CSI report is the smaller value between the first priority value and the second priority value; or,

[0052] The priority value of the CSI report is the sum of the first priority value and the second priority value; or,

[0053] The priority value of the CSI report is the arithmetic mean of the first priority value and the second priority value.

[0054] By implementing this approach, the priorities of CSIs on two types of time units can be taken into account while reducing computational complexity.

[0055] In one possible implementation, the first CSI for the non-SBFD time unit also includes: at least one measurement result obtained based on the measurement of at least one sub-resource in the second resource, the time unit occupied by the at least one sub-resource in the time domain is a non-SBFD time unit, and the frequency domain resources occupied by the at least one sub-resource in the frequency domain are the same as the frequency domain resources occupied by the first resource in the frequency domain.

[0056] By implementing this approach, CSI of the same frequency domain resources as those of the SBFD time unit can be reported for the non-SBFD time unit, thereby providing information for continuous scheduling of the SBFD time unit and the non-SBFD time unit.

[0057] In a possible implementation, the sending of the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit includes:

[0058] A first CSI report and / or a second CSI report are sent, wherein the first CSI report includes the first CSI for the SBFD time unit, and the second CSI report includes the first CSI for the non-SBFD time unit.

[0059] By implementing this approach, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit can be placed in different CSI reports. Compared with placing the first CSI of the two types of time units in one CSI report, this can reduce the risk of packet loss and does not require modifying the format of the CSI report in the existing standard.

[0060] In a possible implementation, the first CSI report includes a first part and a second part, the first part includes the first CSI for the SBFD time unit, and the second part includes the second CSI for the SBFD time unit;

[0061] The priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit.

[0062] By implementing this approach, the first CSI for the SBFD time unit has a higher priority than the second CSI for the SBFD time unit, and the first CSI is transmitted first, thereby improving the transmission reliability of the first CSI.

[0063] In a possible implementation, the second CSI report includes a first part and a second part, the first part includes the first CSI for the non-SBFD time unit, and the second part includes the second CSI for the non-SBFD time unit;

[0064] The priority of the first CSI for the non-SBFD time unit is higher than the priority of the second CSI for the non-SBFD time unit.

[0065] By implementing this approach, the first CSI for the non-SBFD time unit has a higher priority than the second CSI for the SBFD time unit, and the first CSI is transmitted first, thereby improving the transmission reliability of the first CSI.

[0147] The following explains some of the terms involved in the embodiments of the present application to facilitate understanding by those skilled in the art.

[0148] 1. Time unit

[0149] A time unit is a time domain unit used for signal transmission and can be a radio frame, subframe, slot, mini-slot, or Orthogonal Frequency Division Multiplexing (OFDM) symbol. An OFDM symbol can also be simply called a symbol.

[0150] 2. SBFD time unit, non-SBFD time unit, uplink subband, and downlink subband

[0151] SBFD refers to configuring a frequency domain resource for uplink transmission in the frequency domain of a downlink time unit or a flexible time unit. In the embodiment of the present application, the downlink time unit or the flexible time unit is referred to as an SBFD time unit. Figure 2 (A) is a schematic diagram of an SBFD time unit. The frequency domain resources configured for the SBFD time unit include the frequency domain resources for uplink transmission (in Figure 2 (A) is marked with "U"), and frequency domain resources for downlink transmission (in Figure 2 (A) is marked with "D"). In this embodiment of the application, the downlink or flexible time unit of the frequency domain resources that are not configured in the frequency domain for uplink transmission is called a non-SBFD time unit, such as Figure 2 Time unit 1 in (B) is a non-SBFD time unit. The frequency domain resources configured for the non-SBFD time unit are all used for downlink transmission, that is, the frequency domain resources configured for the non-SBFD time unit are downlink frequency domain resources. Figure 2 Time unit 2, time unit 3, time unit 4 and time unit 5 in (B) are all SBFD time units.

[0152] For example, taking a symbol as the time unit, an SBFD time unit can be referred to as an SBFD symbol, and a non-SBFD time unit can be referred to as a non-SBFD symbol. For example, taking a time slot as the time unit, an SBFD time unit can be referred to as an SBFD time slot, and a non-SBFD time unit can be referred to as a non-SBFD time slot.

[0153] In the embodiment of the present application, a frequency domain resource configured on the SBFD time unit for uplink transmission is called an uplink subband. Figure 2 Middle (A) and Figure 2 As shown in (B), the uplink subband is identified by "U". A frequency domain resource configured in the frequency domain of the SBFD time unit for downlink transmission is called a downlink subband, as shown in Figure 2 Middle (A) and Figure 2As shown in (B), the downlink subband is identified by "D". One or more downlink subbands can be configured on the SBFD time unit, such as Figure 2 As shown in (A), there is a downlink subband, such as Figure 2 As shown in (B), there are two downlink subbands. The names of the uplink subband and the downlink subband are not limited and can also be other names.

[0154] In the embodiments of the present application, a guard band may be a frequency domain resource between adjacent uplink and downlink subbands to reduce transmission interference between the uplink and downlink subbands. The name of the guard band is not limited and may be other names, such as guard band.

[0155] Using uplink and downlink subbands, the base station can simultaneously perform uplink and downlink transmissions within a single time unit, achieving full-duplex operation. Compared to TDD, SBFD offers increased uplink resources, improving uplink coverage. For terminal devices, the base station can configure resources in either the uplink or downlink subband, maintaining half-duplex operation for the terminal.

[0156] 3. The first (Transport Block, TB) and second TB and layer number

[0157] Based on the channel state information measured on a resource, a codebook with n layers can be derived. This codebook of n layers represents the channel state for transmitting n streams. If n is less than or equal to 4, scheduling of one TB is allowed, meaning the CSI includes the channel state information for one TB. When n is greater than 4, scheduling of two TBs is allowed, namely the first TB and the second TB, meaning the channel state information includes the channel state information for two TBs: the first TB and the second TB.

[0158] The first layer in the above n-layer codebook is layer number 0, the second layer in the n-layer codebook is layer number 1, and so on.

[0159] In some embodiments, the network device may configure at least one CSI report for the terminal device, and one CSI report is associated with one or more reference signal resources. The reference signal resource associated with the CSI report can be understood as the CSI measured on the reference signal resource being reported by the associated CSI report. The reference signal resource carries a reference signal sent by the network device for channel measurement, such as but not limited to a channel state information reference signal (Channel State Information Reference Signal, CSI-RS). The reference signal resource can be periodic, semi-continuous or non-periodic. The network device can also indicate the frequency domain subband on which the terminal device needs to measure and report the CSI.

[0160] The terminal device can perform channel measurement on the reference signal on the reference signal resource, obtain the corresponding CSI, and report the CSI to the network device. CSI may include, but is not limited to, at least one of the following information: Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), CSI-RS Resource Indicator (CRI), and Rank Indication (RI).

[0161] When reporting CSI, the terminal device may report the overall CSI of the CSI resource, i.e., the broadband CSI of the CSI resource, or may report the CSI of at least one subband within the CSI resource. The specific subband CSI to be reported may be indicated by the network device.

[0162] The terminal device may report CSI via a CSI report. For example, a CSI report may only include wideband CSI, for example, a CSI report may only include the first part (i.e., CSI part 1), which carries the wideband CSI. For example, a CSI report may include two parts, namely, the first part (i.e., CSI part 1) and the second part (CSI part 2). CSI part 1 includes the CSI of the first TB; CSI part 2 includes the CSI of the second TB.

[0163] Specifically, CSI part 1 includes the wideband CSI and subband CSI of the first TB, and CSI part 2 includes the wideband CSI and subband CSI of the second TB. For example, the description of each field included in the CSI report and the CSI measurement results (also called CSI parameters) in each field can be referred to in 3GPP 38.212.6.3.1.1.2. The following example describes:

[0164] For example, a CSI report includes CSI part 1 and CSI part 2. The fields included in CSI part 1 may be as shown in Table 1:

[0165]

[0166]

[0167] Table 1

[0168] The various fields included in CSI part 2 may be shown in Table 2 and Table 3. Table 2 shows the wideband CSI included in CSI part 2, and Table 3 shows the subband CSI included in CSI part 2.

[0169]

[0170] Table 2

[0171]

[0172] Table 3

[0173] When n CSI reports are carried on an uplink channel, if the uplink channel cannot carry all the contents of the CSI reports, part 2 of the n CSI reports may be partially discarded (partial omission). The discard priority of part 2 is opposite to the priority of the contents in part 2. It can be understood that the higher the priority of the contents of the CSI report, the lower the discard priority. Figure 3 The priority level in the figure is a diagram of the discard priority of the CSI report. From left to right, the discard priority level is from low to high. The higher the discard priority level, the higher the discard priority level. The lower the discard priority level, the less likely it is to be discarded. For example, Figure 3 As shown in FIG, when the uplink channel cannot carry all the contents of the CSI report, the odd-numbered subband CSI in part 2 of CSI report n is discarded first. If the remaining contents are still not carried, the even-numbered subband CSI in part 2 of CSI report n is discarded, and so on. The contents with higher discarding priority are discarded first.

[0174] Figure 3 The CSI reports are numbered 1 to n based on their priority. A lower priority CSI report has a higher priority. A lower priority CSI report is more likely to be discarded, while a higher priority CSI report is less likely to be discarded.

[0175] After the introduction of SBFD, the CSI that needs to be reported may include CSI for SBFD time units and CSI for non-SBFD time units. For example, a reference signal resource is periodic, and the time unit type occupied by the reference signal resource in the time domain varies in different periods, being either SBFD time units or non-SBFD time units. For example, in the first period, the reference signal resource occupies SBFD time units in the time domain, while in the second period, the reference signal resource occupies non-SBFD time units. For another example, among multiple configured reference signal resources, some are associated with SBFD time units, while others are associated with non-SBFD time units. Reference signal resources associated with SBFD time units can be understood as meaning that when a periodic reference signal resource is extended according to a period, only reference signal resources in SBFD time units are valid, and the terminal device performs measurements on these valid reference signal resources. Reference signal resources associated with non-SBFD time units can be understood as meaning that when a periodic reference signal resource is extended according to a period, only reference signal resources in non-SBFD time units are valid, and the terminal device performs measurements on these valid reference signal resources. The above two scenarios requiring reporting of CSI for SBFD time units and CSI for non-SBFD time units are examples only, and more scenarios may be included. While the above describes the need to report CSI for SBFD time units and CSI for non-SBFD time units, in some scenarios, the terminal device may also selectively report CSI for SBFD time units or CSI for non-SBFD time units.

[0176] After the introduction of SBFD, it is necessary to report CSI for SBFD time units and / or CSI for non-SBFD time units. The following describes in detail the specific method of reporting CSI for SBFD time units and / or CSI for non-SBFD time units after the introduction of SBFD.

[0177] It should be noted that the various technical solutions (or embodiments) of this application can be implemented independently or in combination based on certain internal connections. This application is not limited thereto. Furthermore, the various terms and definitions between the various embodiments can be referenced to each other. In each embodiment of this application, different implementations can also be implemented in combination or independently.

[0178] Please refer to Figure 4 , is a flowchart of a reporting method provided in an embodiment of the present application, such as Figure 4 As shown, the reporting method of this embodiment includes but is not limited to the following steps:

[0179] 400. The terminal device obtains a first CSI for an SBFD time unit and / or a first CSI for a non-SBFD time unit.

[0180] Step 400 is an optional step. For example, step 400 may be replaced by the terminal device determining the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit.

[0181] For example, the terminal device may obtain the first CSI for the SBFD time unit in the following manner:

[0182] The terminal device receives and measures the reference signal on the first resource to obtain the first CSI for the SBFD time unit. The reference signal can be a CSI-RS. The time unit occupied by the first resource in the time domain is the SBFD time unit, and the frequency domain resource occupied by the first resource in the frequency domain is the downlink subband corresponding to the SBFD time unit. The frequency domain resources configured for the SBFD time unit include a downlink subband and an uplink subband, and the downlink subband corresponding to the SBFD time unit is the downlink subband configured for the SBFD time unit.

[0183] Exemplarily, the frequency domain resources occupied by the first resource in the frequency domain are the frequency domain resources of the reference signal resources configured by the network device excluding the frequency domain resources outside the uplink sub-band, and the frequency domain resources are located in the downlink sub-band. Figure 5 (A) is described with an example, Figure 5 As shown in (A), 500 represents the frequency domain resource of the reference signal resource, 501 represents a downlink subband corresponding to the SBFD time unit, 502 represents another downlink subband corresponding to the SBFD time unit, and 503 represents the uplink subband corresponding to the SBFD time unit. The frequency domain resource occupied by the first resource in the frequency domain is the frequency domain resource 500 of the reference signal resource excluding the uplink subband 503, that is, the frequency domain resource occupied by the first resource in the frequency domain is the frequency domain resource represented by 504 and 505. The first resource occupies the SBFD time unit in the time domain. Figure 5 The gray filled area in (A) is a schematic diagram of the first resource.

[0184] For example, the terminal device may obtain the first CSI for the non-SBFD time unit in the following manner:

[0185] The terminal device receives and measures the reference signal on the second resource to obtain the first CSI for the non-SBFD time unit. The time unit occupied by the second resource in the time domain is the non-SBFD time unit, and the frequency domain resource occupied by the second resource in the frequency domain is the frequency domain resource corresponding to the non-SBFD time unit. The frequency domain resource corresponding to the non-SBFD time unit is used for downlink transmission. Exemplarily, the frequency domain resource occupied by the second resource in the frequency domain is the frequency domain resource of the reference signal resource configured by the network device. Figure 5 (B) gives an example description, such as Figure 5 As shown in (B), 600 represents the frequency domain resources of the reference signal, and 601 represents all frequency domain resources corresponding to the non-SBFD time unit. In this embodiment of the present application, the frequency domain resources occupied by the second resource in the frequency domain are the frequency domain resources of the reference signal, that is, 600 represents the frequency domain resources occupied by the second resource in the frequency domain. The second resource occupies the non-SBFD time unit in the time domain. Figure 5 The gray filled area in (B) is a schematic diagram of the second resource.

[0186] The first CSI for the SBFD time unit includes at least one CSI measurement result obtained based on the first resource measurement, and the first CSI for the non-SBFD time unit includes at least one CSI measurement result obtained based on the second resource measurement. The at least one CSI measurement result may include, but is not limited to, at least one of the following: CSI-RS resource indicator (CSI-RSresource indicator, CRI), channel quality indicator (CQI), rank indicator (RI), layer indicator (LI), reference signal receiver power (RSRP), precoding matrix indicator (PMI), SS / PBCH block resource indicator (SS / PBCHRI), etc.

[0187] 401. The terminal device sends the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit. Correspondingly, the network device receives the first CSI for the SBFD time unit and / or the first CSI for the non-SBFD time unit.

[0188] The first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit may be included in the same CSI report, or included in different CSI reports, for example, the first CSI is included in the first CSI report, and the second CSI is included in the second CSI report.

[0189] In one implementation, the first CSI for the SBFD time unit may include the wideband CSI for the SBFD time unit. The wideband CSI may be understood as the CSI calculated based on the wideband, that is, the CSI calculated based on all frequency domain resources of the first resource, such as Figure 5 As shown in (A), the CSI calculated based on the frequency domain resources represented by 504 and the frequency domain resources represented by 505 may be the wideband CSI for the SBFD time unit. Similarly, the first CSI for the non-SBFD time unit may include the wideband CSI for the non-SBFD time unit, that is, the CSI calculated based on the entire wideband of the second resource, for example, based on Figure 5 The CSI calculated by 600 in (B) indicates frequency domain resources, which is the wideband CSI for the non-SBFD time unit.

[0190] In another implementation, the first CSI for an SBFD time unit may include wideband CSI and subband CSI for the SBFD time unit. The subband CSI for the SBFD time unit can be understood as CSI calculated based on a subband in a first resource. The first resource includes multiple subbands, each of which has corresponding subband CSI. The first CSI for a non-SBFD time unit may include wideband CSI and subband CSI for the non-SBFD time unit. The subband CSI for the non-SBFD time unit can be understood as CSI calculated based on a subband in a second resource. The second resource includes multiple subbands, each of which has corresponding subband CSI.

[0191] As one example, the terminal device may send the first CSI for the SBFD time unit to the network device; as another example, the terminal device may send the first CSI for the non-SBFD time unit to the network device; as yet another example, the terminal device may send the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit to the network device.

[0192] The following example describes the format of the CSI report:

[0193] In a first possible implementation, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit may be carried in the same CSI report.

[0194] The following example illustrates the format of a CSI report.

[0195] In mode 1, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit may be carried in the first part of the CSI report.

[0196] It can be understood that the CSI report may include only the first part and not the second part, or the CSI report may include both the first part and the second part.

[0197] In some embodiments, the first part of the CSI report includes at least one field, each field including one CSI measurement result in the first CSI for the SBFD time unit and one CSI measurement result in the first CSI for the non-SBFD time unit. For example, one field in the first part of the CSI report is a CRI, which may include the CRI in the first CSI for the SBFD time unit and the CRI in the first CSI for the non-SBFD time unit. Taking Table 4 as an example, one field may include one CSI measurement result in the first CSI for the SBFD time unit and one CSI measurement result in the first CSI for the non-SBFD time unit. In some embodiments, the one CSI measurement result in the first CSI for the SBFD time unit and one CSI measurement result in the first CSI for the non-SBFD time unit carried in one field in Table 4 may be indicated by two pieces of information, or by one piece of information, i.e., the one piece of information may indicate one CSI measurement result in the first CSI for the SBFD time unit and one CSI measurement result in the first CSI for the non-SBFD time unit.

[0198]

[0199] Table 4

[0200] In other embodiments, the first CS for the SBFD time unit may be present in the first part of the CSI report in the form of a domain set, and the first CSI for the non-SBFD time unit may also be present in the first part of the CSI report in the form of a domain set. Specifically, the first part of the CSI report includes a first domain set and a second domain set, the first domain set includes at least one first domain, each first domain includes a CSI measurement result included in the first CSI for the SBFD time unit, and the second domain set includes at least one second domain, each second domain includes a CSI measurement result included in the first CSI for the non-SBFD time unit.

[0201] Exemplarily, at least one first domain for an SBFD time unit may include, for example, CRI, RI, the wideband CQI of the first TB, the subband differential CQI of the first TB, an indication of the number of non-zero wideband amplitude coefficients M0 corresponding to layer number 0, an indication of the number of non-zero wideband amplitude coefficients M0 corresponding to layer number 1, etc. The first TB, layer number 0, and layer number 1 are obtained based on the channel state information measured on the first resource. For details, please refer to the terminology description in the aforementioned embodiment. For example, at least one first domain for a non-SBFD time unit may include, for example, CRI, RI, the wideband CQI of the first TB, the subband differential CQI of the first TB, an indication of the number of non-zero wideband amplitude coefficients M0 corresponding to layer number 0, an indication of the number of non-zero wideband amplitude coefficients M0 corresponding to layer number 1, etc. The first TB, layer number 0, and layer number 1 are obtained based on the channel state information measured on the second resource. For details, please refer to the terminology description in the aforementioned embodiment. The first domain carries the CSI measurement result corresponding to the first CSI for the SBFD time unit, and the second domain carries the CSI measurement result corresponding to the first CSI for the non-SBFD time unit. For example, for the CRI domain, the CRI domain in the first domain set carries the CRI in the first CSI for the SBFD time unit, and the CRI domain in the second domain set carries the CRI in the first CSI for the non-SBFD time unit.

[0202] In an embodiment of the present application, multiple domains in the first part of the CSI report can be divided into a first domain set and a second domain set based on the carrying content of each domain in the first part. The domains in the first domain set are called first domains, and the first domains carry CSI measurement results in the first CSI for SBFD time units. The domains in the second domain set are called second domains, and the second domains carry CSI measurement results in the first CSI for non-SBFD time units.

[0203] It should be noted that, in actual implementation, the first domain set and the second domain set may not be divided. The first domain set and the second domain set can be understood as a concept of logical division. For example, the first part of the CSI report includes a+b domains. Among them, each domain from the 1st domain to the ath domain carries a CSI measurement result in the first CSI for the SBFD time unit, and each domain from the a+1th domain to the a+bth domain carries a CSI measurement result in the first CSI for the non-SBFD time unit. a and b are both positive integers greater than 1. In this case, the 1st domain to the ath domain can be regarded as the first domain set, and the a+1th domain to the a+bth domain can be regarded as the second domain set. For example, Figure 6 As shown in (A), in the first part of the CSI report, the position of the first domain set is before the position of the second domain set.

[0204] For another example, the first part of the CSI report includes a+b domains. Among them, each domain from the 1st domain to the bth domain carries a measurement result in the first CSI for the non-SBFD time unit, and each domain from the b+1th domain to the a+bth domain carries a measurement result in the first CSI for the SBFD time unit. a and b are both positive integers greater than 1. In this case, the 1st domain to the bth domain can be regarded as the second domain set, and the b+1th domain to the a+bth domain can be regarded as the first domain set. Figure 6 As shown in (B), in the first part of the CSI report, the position of the second domain set is before the position of the first domain set.

[0205] In approach 1, the CSI report may further include a second part, which includes second CSI for SBFD time units and / or includes second CSI for non-SBFD time units. The second CSI for the SBFD time unit includes at least one CSI measurement result obtained based on the first resource measurement, and the second CSI for the non-SBFD time unit includes at least one CSI measurement result obtained based on the second resource measurement.

[0206] For example, the CSI measurement result included in the first CSI for the SBFD time unit may be the CSI of the first TB. The second CSI for the SBFD time unit may be the CSI of the second TB. For example, a codebook with N layers can be obtained based on the channel state information measured based on the first resource. If N is greater than 4, two TBs are allowed to be scheduled, namely the first TB and the second TB, that is, the channel state information includes the channel state information of the two TBs, the channel state information of the first TB in the channel state information is referred to as the CSI of the first TB, and the channel state information of the second TB in the channel state information is referred to as the CSI of the second TB.

[0207] For example, the CSI measurement result included in the first CSI for a non-SBFD time unit may be the CSI of the first TB, and the second CSI for the non-SBFD time unit may be the CSI of the second TB. For example, a codebook having m layers may be obtained based on the channel state information measured based on the second resource. If m is greater than 4, scheduling of two TBs is allowed, namely the first TB and the second TB. That is, the channel state information includes channel state information of the two TBs. The channel state information of the first TB in the channel state information is referred to as the CSI of the first TB, and the channel state information of the second TB in the channel state information is referred to as the CSI of the second TB.

[0208] For example, the priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit. If the transmission resources are able to carry the first CSI for the SBFD time unit and the second CSI for the SBFD time unit, the information is transmitted in descending order of priority, i.e., the higher the priority, the higher the priority. If the transmission resources are unable to carry the first CSI for the SBFD time unit and the second CSI for the SBFD time unit, the lower the priority, the less likely it is to be transmitted, i.e., it will be discarded.

[0209] For example, the priority of the first CSI for a non-SBFD time unit is higher than the priority of the second CSI for a non-SBFD time unit. If the transmission resources are able to carry the first CSI for a non-SBFD time unit and the second CSI for a non-SBFD time unit, the information is transmitted in descending order of priority, i.e., the higher the priority, the higher the transmission priority. If the transmission resources are unable to carry the first CSI for a non-SBFD time unit and the second CSI for a non-SBFD time unit, the lower the priority, the less likely it is to be transmitted, i.e., the information will be discarded.

[0210] In some embodiments, the second part of the CSI report includes at least one field, each field including one CSI measurement result in the second CSI for the SBFD time unit and one CSI measurement result in the second CSI for the non-SBFD time unit. For example, one field in the second part of the CSI report is a PMI, which may include the PMI in the second CSI for the SBFD time unit and the PMI in the second CSI for the non-SBFD time unit. The one CSI measurement result in the second CSI for the SBFD time unit and the one CSI measurement result in the second CSI for the non-SBFD time unit carried in one field in the second part of the CSI report may be indicated by two pieces of information, or by one piece of information, i.e., the one piece of information may indicate one CSI measurement result in the second CSI for the SBFD time unit and one CSI measurement result in the second CSI for the non-SBFD time unit.

[0211] In some other embodiments, the second part of the CSI report includes a third field set and a fourth field set, wherein the third field set includes at least one third field, each third field including a CSI measurement result for a second CSI include of an SBFD time unit, and the fourth field set includes at least one fourth field, each fourth field including a CSI measurement result for a second CSI include of a non-SBFD time unit.

[0212] The at least one third field may, for example, include: the wideband CQI, RI, PMI wideband information parameters of the second TB, subband differential CQI of the second TB, PMI subband information of the second TB, etc. The second TB may be obtained based on the channel state information measured on the first resource. The at least one fourth field may, for example, include: the wideband CQI, RI, PMI wideband information parameters of the second TB, subband differential CQI of the second TB, PMI subband information of the second TB, etc. The second TB may be obtained based on the channel state information measured on the second resource.

[0213] It should be noted that, in actual implementation, the third domain set and the fourth domain set may not be divided. The third domain set and the fourth domain set can be understood as a concept of logical division. For example, the second part of the CSI report includes c+d domains. Among them, each domain from the 1st domain to the cth domain carries a CSI measurement result in the second CSI for the SBFD time unit, and each domain from the c+1th to the c+dth domain carries a CSI measurement result in the second CSI for the non-SBFD time unit. c and d are both positive integers greater than 1. In this case, the 1st domain to the cth domain can be regarded as the first domain set, and the c+1th to c+dth domains can be regarded as the second domain set. For example, as Figure 7 As shown in (A), in the second part of the CSI report, the position of the third field set is before the position of the fourth field set.

[0214] For another example, the second part of the CSI report includes c+d domains. Among them, each domain from the 1st domain to the dth domain carries a CSI measurement result in the second CSI for the non-SBFD time unit, and each domain from the d+1th domain to the c+dth domain carries a CSI measurement result in the second CSI for the SBFD time unit. Both c and d are positive integers greater than 1. In this case, the 1st domain to the dth domain can be regarded as the fourth domain set, and the d+1th domain to the c+dth domain can be regarded as the third domain set. For example, Figure 7 As shown in (B), in the second part of the CSI report, the position of the fourth field set is before the position of the third field set.

[0215] In method 2, one of the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit can be carried in the first part of the CSI report, and the other of the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit can be carried in the second part of the CSI report.

[0216] As an example, the first part of the CSI report includes the first CSI for the SBFD time unit, and the second part of the CSI report includes the first CSI for the non-SBFD time unit.

[0217] As another example, the first part of the CSI report includes the first CSI for the non-SBFD time unit, and the second part of the CSI report includes the first CSI for the SBFD time unit.

[0218] Placing the first CSI for the SBFD time unit or the first CSI for the non-SBFD time unit in the second part of the CSI report may be preconfigured by the network device or may be specified by a standard.

[0219] In mode 2, the CSI report may also include a second part, the second part including the second CSI for the SBFD time unit, and / or the second part including the second CSI for the non-SBFD time unit. The priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit, and the priority of the first CSI for the non-SBFD time unit is higher than the priority of the second CSI for the non-SBFD time unit, that is, the priority of the first CSI for the same type of time unit is higher than the priority of the second CSI. Among them, when the transmission resources are able to carry the information to be transmitted, it is transmitted in order from high to low priority, that is, the higher the priority of the information, the higher the priority is transmitted. When the transmission resources cannot carry all the information to be transmitted, the lower the priority of the information, the less likely it is to be transmitted, and the lower the priority of the information will be discarded first.

[0220] For ease of description, the first CSI for the first time unit will be placed in the first part of the CSI report, and the first CSI for the second time unit will be placed in the second part of the CSI report. If the first time unit is an SBFD time unit, the second time unit is a non-SBFD time unit. If the first time unit is a non-SBFD time unit, the second time unit is an SBFD time unit. Among them, at least one CSI measurement result in the first CSI for the second time unit can be present in the second part of the CSI report in the form of a domain set. Specifically, refer to the description in the aforementioned embodiment that the first CSI for the SBFD time unit can be present in the first part of the CSI report in the form of a domain set, or refer to the aforementioned embodiment that the first CSI for the non-SBFD time unit can also be present in the first part of the CSI report in the form of a domain set.

[0221] The priority of the first CSI for the first time unit placed in the first part of the CSI report is higher than the priority of the first CSI for the second time unit placed in the second part of the CSI report. In the second part of the CSI report, the priority of the first CSI for the second time unit is the highest, that is, the priority of the first CSI for the second time unit is higher than the priority of the second CSI for the first time unit, and the priority of the first CSI for the second time unit is higher than the priority of the second CSI for the second time unit. In particular, when the transmission resources are able to carry the information to be transmitted, it is transmitted in order from high to low priority, that is, the higher the priority of the information, the higher the priority is transmitted. In the case that the transmission resources cannot carry all the information to be transmitted, the lower the priority of the information, the less likely it is to be transmitted, and the lower the priority of the information will be discarded first.

[0222] In a second possible implementation, the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit may be carried in different CSI reports, respectively.

[0223] For example, the first CSI for the SBFD time unit is carried in the first CSI report, and the first CSI for the non-SBFD time unit is carried in the second CSI report. It is understandable that if the terminal device reports one of the first CSI for the SBFD time unit and the first CSI for the non-SBFD time unit, the terminal device can report the first CSI report or the second CSI report. The following examples illustrate the formats of the first CSI report and the second CSI report:

[0224] In some embodiments, the first CSI report includes a first part and a second part, the first part including the first CSI for the SBFD time unit, and the second part including the second CSI for the SBFD time unit. Exemplarily, the first part of the first CSI report includes at least one field, each field including a CSI measurement result for the first CSI for the SBFD time unit. Exemplarily, the second part of the first CSI report includes at least one field, each field including a CSI measurement result for the second CSI for the SBFD time unit. It is understood that if the first CSI report does not include the second CSI for the SBFD time unit, then the first CSI report only includes the contents of the first part.

[0225] In the first CSI report, the priority of the first CSI for the SBFD time unit is higher than the priority of the second CSI for the SBFD time unit.

[0226] In some other embodiments, the second CSI report includes a first part and a second part, the first part including the first CSI for the non-SBFD time unit, and the second part including the second CSI for the non-SBFD time unit. Exemplarily, the first part of the second CSI report includes at least one field, each field including a CSI measurement result in the first CSI for the non-SBFD time unit. Exemplarily, the second part of the second CSI report includes at least one field, each field including a CSI measurement result in the second CSI for the non-SBFD time unit. It is understood that if the second CSI report does not include the second CSI for the non-SBFD time unit, then the second CSI report only includes the contents of the first part.

[0227] In the second CSI report, the priority of the first CSI for the non-SBFD time unit is higher than the priority of the second CSI for the non-SBFD time unit.

[0228] In the first possible implementation manner above, the same CSI report may include CSI for the SBFD time unit (the CSI may include the first CSI, or include the first CSI and the second CSI) and CSI for the non-SBFD time unit (the CSI may include the first CSI, or include the first CSI and the second CSI). Figure 8 For details on how to prioritize CSI reports, see Figure 8 , which is a flow chart of a method for determining CSI report priority provided in an embodiment of the present application:

[0229] 801. Obtain a first priority value according to a CSI measurement result based on a first resource.

[0230] The CSI measurement result of the first resource may include a CSI measurement result of a first CSI for an SBFD time unit, or the CSI measurement result of the first resource may include a CSI measurement result of the first CSI for an SBFD time unit and a CSI measurement result of a second CSI for an SBFD time unit. The CSI measurement result used to determine the priority value may be at least one of RSRP, SINR, or CQI.

[0231] Exemplarily, if the CSI measurement result of the first resource includes RSRP or SINR, the determined first priority value is the first value, and if the CSI measurement result of the first resource includes CQI, the determined first priority value is the second value. For example, the first priority value Pri1 satisfies the following formula:

[0232] Pri1=2·N cells ·M s y+N cells ·Ms k+M s c+s

[0233] Among them, y = one of 0, 1, 2, and 3. The value of y is determined by the channel type carrying the CSI report and the time domain periodicity of the CSI report. For example, if the channel carrying the CSI report is PUSCH and the CSI report is reported aperiodically, then y = 0; if the channel carrying the CSI report is PUSCH and the CSI report is reported semi-persistently, then y = 1; if the channel carrying the CSI report is PUCCH and the CSI report is reported semi-persistently, then y = 2; if the channel carrying the CSI report is PUCCH and the CSI report is reported periodically, then y = 3.

[0234] k=0 or 1. If the CSI measurement result configured by the network device for the SBFD time unit includes RSRP or SINR, that is, the CSI measurement result of the first resource includes RSRP or SINR, then k=0; if the CSI measurement result configured by the network device for the SBFD time unit does not include RSRP or SINR, that is, the CSI measurement result of the first resource does not include RSRP or SINR, then k=1.

[0235] c represents the serving cell ID of the reference signal corresponding to the CSI report.

[0236] s indicates the ID of the CSI report.

[0237] M s Indicates the maximum number of CSI report configurations.

[0238] N cells Indicates the maximum number of service cells.

[0239] The smaller the first priority value Pri1 is, the higher the corresponding priority is.

[0240] 802. Obtain a second priority value according to a CSI measurement result based on a second resource.

[0241] The CSI measurement result of the second resource may include a CSI measurement result of the first CSI for the non-SBFD time unit, or the CSI measurement result of the second resource may include a CSI measurement result of the first CSI for the non-SBFD time unit and a CSI measurement result of the second CSI for the non-SBFD time unit. The CSI measurement result used to determine the priority value may be at least one of RSRP, SINR, or CQI.

[0242] Exemplarily, if the CSI measurement result of the second resource includes RSRP or SINR, the determined second priority value is the third value; if the CSI measurement result of the second resource includes CQI, the determined second priority value is the fourth value. For example, the second priority value Pri2 satisfies the following formula:

[0243] Pri2=2·N cells ·M s y+N cells ·M s k+M s c+s

[0244] Among them, y = one of 0, 1, 2, and 3. The value of y is determined by the channel type carrying the CSI report and the time domain periodicity of the CSI report. For example, if the channel carrying the CSI report is PUSCH and the CSI report is reported aperiodically, then y = 0; if the channel carrying the CSI report is PUSCH and the CSI report is reported semi-persistently, then y = 1; if the channel carrying the CSI report is PUCCH and the CSI report is reported semi-persistently, then y = 2; if the channel carrying the CSI report is PUCCH and the CSI report is reported periodically, then y = 3.

[0245] k = 0 or 1, where the value of k is determined by the CSI measurement result of the second resource. If the CSI measurement result configured by the network device for the non-SBFD time unit includes RSRP or SINR, that is, the CSI measurement result of the second resource includes RSRP or SINR, then k = 0; if the CSI measurement result configured by the network device for the non-SBFD time unit does not include RSRP or SINR, that is, the CSI measurement result of the second resource does not include RSRP or SINR, then k = 1.

[0246] c represents the serving cell ID of the reference signal corresponding to the CSI report.

[0247] s indicates the ID of the CSI report.

[0248] M s Indicates the maximum number of CSI report configurations.

[0249] N cells Indicates the maximum number of service cells.

[0250] The smaller the second priority value Pri2 is, the higher the corresponding priority is.

[0251] 803. Determine a priority value of the CSI report according to the first priority value and the second priority value.

[0252] It is necessary to note that step 801 and step 802 can be executed simultaneously, or step 801 can be before step 802, or step 802 can be before step 801, but both step 801 and step 802 are before step 803. This application does not limit the order of step 801 and step 802.

[0253] As an example, the priority value of the CSI report is a larger value between the first priority value Pri1 and the second priority value Pri2.

[0254] As another example, the priority value of the CSI report is a smaller value between the first priority value Pri1 and the second priority value Pri2.

[0255] As yet another example, the priority value of the CSI report is the sum of the first priority value Pri1 and the second priority value Pri2.

[0256] As another example, the priority value of the CSI report is the arithmetic average of the first priority value Pri1 and the second priority value Pri2. For example, the priority value of the CSI report is

[0257] Alternatively, the priority value of the CSI report may be determined based on the first priority value Pri1 and the second priority value Pri2 through other calculation methods, for example, ɑ1*first priority value Pri1+ɑ2*second priority value Pri2 is the priority value of the CSI report, where ɑ1 and ɑ2 are coefficients used to calculate the priority value of the CSI report. The coefficient may be predefined by the protocol, or may be indicated by the network device to the terminal device, or may be determined by the terminal device based on a certain policy or rule, and there is no limitation on this.

[0258] When a terminal device needs to send N CSI reports, due to resource limitations, it is unable to carry all the contents of the N CSI reports and may discard the measurement results included in the second part of the CSI report. The CSI measurement results included in the second part of the CSI report may include wideband CSI for SBFD time units, wideband CSI for non-SBFD time units, subband CSI for SBFD time units, and subband CSI for non-SBFD time units. The wideband CSI for SBFD time units can be understood as the CSI calculated based on all frequency domain resources of the first resource, such as Figure 5 As shown in (A), the CSI calculated based on the frequency domain resources represented by 504 and the frequency domain resources represented by 505 is the wideband CSI for the SBFD time unit. The wideband CSI for the non-SBFD time unit can be understood as the CSI calculated based on the entire wideband of the second resource, for example, based on Figure 5The CSI calculated based on the frequency domain resources represented by 602 in (B) is the wideband CSI for non-SBFD time units. The wideband CSI for SBFD time units or non-SBFD time units included in the second part of the CSI report can be, for example, the CSI measurement results for each domain shown in Table 2.

[0259] The subband CSI for SBFD time units included in the second part of the CSI report can be understood as CSI calculated based on a subband in the first resource, where the first resource includes multiple subbands, each with corresponding subband CSI. The subband CSI for non-SBFD time units included in the second part of the CSI report can be understood as CSI calculated based on a subband in the second resource, where the second resource includes multiple subbands, each with corresponding subband CSI. The subband CSI for SBFD or non-SBFD time units included in the second part of the CSI report can be, for example, the CSI measurement results for each domain shown in Table 3.

[0260] The following two implementations illustrate the discarding priority order of CSI measurement results included in the second part of N CSI reports. A measurement result with a higher discarding priority is discarded first. It can be understood that if the first CSI for an SBFD time unit or the first CSI for a non-SBFD time unit is placed in the second part of the CSI report, the first CSI has the lowest discarding priority:

[0261] In a first implementation, the order of discarding priority of the measurement results included in the second parts of N CSI reports, from low to high, is: the wideband CSI for the first time unit included in the second parts of all CSI reports in the N CSI reports, the wideband CSI for the second time unit included in the second parts of all CSI reports in the N CSI reports, the subband CSI included in the second part of CSI report 1 in the N CSI reports, the subband CSI included in the second part of CSI report 2 in the N CSI reports, and so on, up to the subband CSI included in the second part of CSI report N in the N CSI reports; the order of discarding priority of the subband CSI included in CSI report i, from low to high, is: the subband CSI for the first time unit, then the subband CSI for the second time unit. The first time unit is an SBFD time unit and the second time unit is a non-SBFD time unit; or the first time unit is a non-SBFD time unit and the second time unit is an SBFD time unit.

[0262] The number of the CSI report is determined according to the priority of the CSI report. The higher the priority of the CSI report, the smaller the number of the CSI report. For example, CSI report 1 has the highest priority, followed by CSI report 2, and so on. The higher the priority of the CSI report, the lower the discarding priority.

[0263] For CSI report i, the discard priority of the subband CSI for the first time unit is lower than the discard priority of the subband CSI for the second time unit. The subband CSI for the first time unit or the second time unit is further divided into even subband CSI and odd subband CSI. Even subbands can be understood as subbands with even subband numbers or index numbers, and odd subbands can be understood as subbands with odd subband numbers or index numbers. The discard priority of even subband CSI for the same type of time unit is lower than the discard priority of odd subband CSI, or the discard priority of odd subband CSI for the same type of time unit is lower than the discard priority of even subband CSI. The following example illustrates that the discarding priority of even subband CSI is lower than that of odd subband CSI in the same time unit type. The discarding priority of subband CSI included in the second part of CSI report i is, from low to high, as follows: even subband CSI for the first time unit, odd subband CSI for the first time unit, even subband CSI for the second time unit, and odd subband CSI for the second time unit. The value of i ranges from 1 to N, where N is a positive integer greater than or equal to 1. An even subband may refer to a subband whose number or index is an even number.

[0264] In the following, the first time unit is an SBFD time unit and the second time unit is a non-SBFD time unit. For example, the value of N is equal to 2, that is, there are two CSI reports, namely CSI report 1 and CSI report 2. Then, the order of discarding priority of the measurement results included in the second part of the two CSI reports is as follows from low to high: the wideband CSI for the SBFD time unit included in the second part of all CSI reports in the two CSI reports, the wideband CSI for the non-SBFD time unit included in the second part of all CSI reports in the two CSI reports, the even subband CSI for the SBFD time unit included in the second part of CSI report 1, and the even subband CSI for the SBFD time unit included in the second part of CSI report 2. The second part of CSI Report 1 includes odd subband CSI for SBFD time units, the second part of CSI Report 1 includes even subband CSI for non-SBFD time units, the second part of CSI Report 1 includes odd subband CSI for non-SBFD time units, the second part of CSI Report 2 includes even subband CSI for SBFD time units, the second part of CSI Report 2 includes odd subband CSI for SBFD time units, the second part of CSI Report 2 includes even subband CSI for non-SBFD time units, and the second part of CSI Report 2 includes odd subband CSI for non-SBFD time units.

[0265] In a second implementation, the order of discarding priority of the measurement results included in the second parts of N CSI reports, from low to high, is as follows: the wideband CSI for SBFD time units and non-SBFD time units included in the second parts of all CSI reports in the N CSI reports, the subband CSI included in the second part of CSI report 1 in the N CSI reports, the subband CSI included in the second part of CSI report 2 in the N CSI reports, and so on, up to the subband CSI included in the second part of CSI report N in the N CSI reports. The order of discarding priority of the subband CSI included in CSI report i, from low to high, is as follows: the even subband CSI for SBFD time units and non-SBFD time units, and the odd subband CSI for SBFD time units and non-SBFD time units, where i ranges from 1 to N, and N is a positive integer greater than or equal to 1.

[0266] The number of the CSI report is determined according to the priority of the CSI report. For details, please refer to the description of the first implementation method.

[0267] Assume that the value of N is 2, that is, two CSI reports are included, namely CSI Report 1 and CSI Report 2. Then, the order of discarding priority of the measurement results included in the second parts of the two CSI reports, from low to high, is as follows: the wideband CSI for SBFD time units and non-SBFD time units included in the second parts of all CSI reports in the two CSI reports, the even subband CSI for SBFD time units and non-SBFD time units included in the second part of CSI Report 1, the odd subband CSI for SBFD time units and non-SBFD time units included in the second part of CSI Report 1, the even subband CSI for SBFD time units and non-SBFD time units included in the second part of CSI Report 2, and the odd subband CSI for SBFD time units and non-SBFD time units included in the second part of CSI Report 2.

[0268] In some embodiments, the discard priority of the wideband CSI for SBFD time units is lower than that for non-SBFD time units. Alternatively, the discard priority of the wideband CSI for non-SBFD time units is lower than that for SBFD time units.

[0269] In some embodiments, the discard priority of the even subband CSI for the SBFD time unit is lower than the discard priority of the even subband CSI for the non-SBFD time unit. Alternatively, the discard priority of the even subband CSI for the non-SBFD time unit is lower than the discard priority of the even subband CSI for the SBFD time unit.

[0270] In some embodiments, the drop priority of odd-numbered subband CSI for SBFD time units is lower than the drop priority of odd-numbered subband CSI for non-SBFD time units. Alternatively, the drop priority of odd-numbered subband CSI for non-SBFD time units is lower than the drop priority of odd-numbered subband CSI for SBFD time units.

[0271] In the above description, the first CSI for the non-SBFD time unit includes: at least one CSI measurement result obtained based on the second resource measurement. In some scenarios, the first CSI for the non-SBFD time unit may also include at least one CSI measurement result obtained based on the measurement of at least one sub-resource in the second resource. The time unit occupied by the at least one sub-resource in the time domain is a non-SBFD time unit, and the frequency domain resources occupied by the at least one sub-resource in the frequency domain are the same as the frequency domain resources occupied by the first resource in the frequency domain, that is, the frequency domain resources occupied by the at least one sub-resource in the frequency domain are the frequency domain resources of the second resource excluding the frequency domain resources with the same uplink sub-band and / or guard band. The following is combined with Figure 9The second resource and at least one sub-resource are exemplified. Figure 9 (A) is a schematic diagram of the second resource. The second resource occupies non-SBFD time units in the time domain. The second resource in the frequency domain is the same as the reference signal resource, that is, the resource in the gray filled area is the second resource. Figure 9 Middle (B) is a schematic diagram of two sub-resources of a non-SBFD time unit, that is, the frequency domain resources occupied by the two sub-resources in the frequency domain are the frequency domain resources of the second resource after excluding the uplink subband and the guard band, and the two sub-resources occupy a non-SBFD time unit in the time domain.

[0272] The reporting method of the at least one CSI measurement result obtained based on at least one sub-resource measurement and included in the first CSI of the non-SBFD time unit may refer to the reporting method of the first CSI of the SBFD time unit in the aforementioned embodiment.

[0273] The second CSI for the non-SBFD time unit may include, in addition to at least one CSI measurement result obtained based on the second resource measurement, at least one CSI measurement result obtained based on the at least one sub-resource measurement.

[0274] The reporting method of the at least one CSI measurement result obtained based on at least one sub-resource measurement and included in the second CSI of the non-SBFD time unit may refer to the reporting method of the second CSI of the SBFD time unit in the aforementioned embodiment.

[0275] In some embodiments, the terminal device may report at least one CSI measurement result obtained based on the second resource measurement and at least one CSI measurement result obtained based on the at least one sub-resource measurement, including the following two optional implementations:

[0276] In a first implementation, the network device configures a reference signal resource for a non-SBFD time unit, and the frequency domain resources of the reference signal resource include the same frequency domain resources as the frequency domain resources of the uplink subband. Optionally, the frequency domain resources of the reference signal resource may also include frequency domain resources that are different from the frequency domain resources of the uplink subband.

[0277] When the terminal device reports the CSI measurement result obtained based on the second resource measurement, all frequency domain resources of the reference signal resource are valid measurement resources, that is, the frequency domain resources of the second resource used for measurement are all frequency domain resources of the reference signal resource, such as Figure 9 Schematic diagram of the second resource shown in (A), the terminal device reports the CSI measurement results obtained based on the second resource measurement.

[0278] When the terminal device reports the CSI measurement result obtained based on the measurement of at least one sub-resource, the frequency domain resources of the effective measurement resources are the frequency domain resources remaining after the frequency domain resources of the reference signal resources exclude the frequency domain resources that are the same as the frequency domain resources of the uplink sub-band and / or the guard band, that is, the frequency domain resources of at least one sub-resource do not include the frequency domain resources that are the same as the frequency domain resources of the uplink sub-band and / or the guard band, such as Figure 9 As shown in (B), the gray-filled area is a schematic diagram of at least one sub-resource, and the frequency domain resources of the two sub-resources are the frequency domain resources of the second resource (also called the reference signal resource) excluding the frequency domain resources that are the same as the uplink sub-band and the guard band. The terminal device reports the CSI measurement result obtained based on the measurement of the at least one sub-resource.

[0279] In a second implementation, the network device configures a reference signal resource set for a non-SBFD time unit, where the reference signal resource set includes two types of reference signal resources, for example, a first type of reference signal resource and a second type of reference signal resource. The frequency domain resources of the first type of reference signal resource overlap with the frequency domain resources of the uplink subband, that is, the first type of reference signal resource includes the frequency domain resources corresponding to the uplink subband, and the frequency domain resources of the second type of reference signal resource do not overlap with the frequency domain resources of the uplink subband, that is, the reference signal resources of the second type do not include the frequency domain resources corresponding to the uplink subband.

[0280] When the terminal device reports a CSI measurement result obtained based on the second resource measurement, the second resource is a reference signal resource of the first type. When the terminal device reports a CSI measurement result obtained based on the at least one sub-resource measurement, the at least one sub-resource is a reference signal resource of the second type.

[0281] As described above, for non-SBFD time units, the terminal device may also report CSI measurement results measured on at least one sub-resource whose frequency domain resources are the same as the frequency domain resources of the first resource corresponding to the SBFD time unit, thereby facilitating the determination of whether continuous transmission is possible between the SBFD time unit and the non-SBFD time unit, for example, Figure 10 As shown, PDSCH transmission spans SBFD time units and non-SBFD time units. By reporting CSI measurement results on sub-resources with the same frequency domain resources as the frequency domain resources of the SBFD time unit, it is convenient for network devices to determine whether PDSCH can be transmitted continuously between SBFD time units and non-SBFD time units.

[0282] In some embodiments, the terminal device may not report the CSI measurement result based on the second resource, but may report the CSI measurement result based on at least one sub-resource. Exemplarily, the terminal device may report the CSI measurement result based on the at least one sub-resource in one CSI report. Exemplarily, the terminal device may report the CSI measurement result for the SBFD time unit and the CSI measurement result of the at least one sub-resource in one CSI report.

[0356] about Figure 12 The specific embodiment description can refer to the description of the aforementioned method embodiment, which will not be repeated here.

[0357] See Figure 13 , Figure 13 3 is a schematic diagram of the structure of a communication device provided in an embodiment of the present application, which is used to implement the functions of the terminal device in the above method embodiment, or to implement the functions of the network device in the above method embodiment. The communication device 300 can be a terminal device or a device for a terminal device. The device for a terminal device can be a chip system or chip within the terminal device. The communication device can also be a network device or a device for a network device. The device for a network device can be a chip system or chip within the network device. The chip system can be composed of a chip or can also include a chip and other discrete devices.

[0358] The communication device 300 includes at least one processor 320 for implementing the data processing function of the terminal device or network device in the method provided in the embodiment of the present application. The communication device 300 may also include a communication interface 310 for implementing the transceiver operation of the terminal device or network device in the method provided in 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 (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates 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, circuit, bus, module or other type of communication interface for communicating with other devices via a transmission medium. For example, the communication interface 310 is used for the communication device 300 to communicate with other devices.

When data needs to be sent wirelessly, the processor 320 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit ( Figure 13 The RF circuit performs RF processing on the baseband signal and transmits it as electromagnetic waves via the antenna (not shown). When data is sent to communication device 300, the RF circuit receives the RF signal via the antenna, converts it into a baseband signal, and outputs the baseband signal to processor 320.
