[0024] The embodiments of this application will be described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this application. It should be noted that any technical features in the same or different embodiments of this application can be combined arbitrarily, and the resulting technology is still within the scope of this application. Furthermore, the technologies, steps, or processes in the embodiments of this application are not indispensable. That is, even if more or fewer technologies, steps, or processes are included than in the embodiments, they are still within the protection scope of this application.

[0025] When the bandwidth supported by the wireless system is limited, a single signaling protocol can be used for configuration. However, when the wireless system supports a larger bandwidth, the existing signaling protocol, being fixed, cannot support the increased bandwidth. Furthermore, when the bandwidth of the data channel is excessively large, how to achieve more efficient data transmission becomes a problem that needs to be addressed.

[0026] Therefore, this application proposes a new resource configuration method that, by adding a signaling signal, enables configuration using the signaling signal when the wireless system supports additional bandwidth, without affecting the UE and configuration in the existing network, and also enables more efficient data transmission.

[0164] In the following embodiments, the resource configuration process is described with the first communication node as the UE and the second communication node as the base station.

[0165] Example 1

[0166] This embodiment describes the process of resource configuration when resource configuration includes at least one of carrier bandwidth configuration, frequency domain start position configuration, and frequency domain bandwidth configuration.

[0167] The base station uses at least one of a first signaling and a second signaling to indicate the carrier bandwidth, frequency domain start position, or frequency domain bandwidth. When the carrier bandwidth or a portion of the bandwidth is less than or equal to a first threshold, or when the system carrier is not within a specific frequency range (or within a first specific frequency range), the base station uses the first signaling to indicate the carrier bandwidth, frequency domain start position, or frequency domain bandwidth. Correspondingly, the UE receives the first signaling and determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth according to the indication of the first signaling. When the carrier bandwidth or a portion of the bandwidth is greater than the first threshold, or when the system carrier is within a specific frequency range (or within a second specific frequency range), the base station uses the second signaling, or uses both the first and second signaling, to indicate the carrier bandwidth, frequency domain start position, or frequency domain bandwidth. Correspondingly, the UE receives the second signaling, or receives both the first and second signaling, and determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth according to the second signaling, or according to the indication of both the first and second signaling. The bandwidth portion refers to a portion of the carrier bandwidth, i.e., a partial carrier bandwidth.

[0168] Bandwidth can be expressed as the number of frequency resources, such as the number of resource blocks (RBs), resource block groups (RBGs), resource elements (REs), or resource element groups (REGs). The frequency domain start position includes at least one of the following: the frequency domain spacing of the system carrier relative to the reference frequency, the frequency hopping value of the Physical Uplink Shared Channel (PUSCH), the frequency domain start position of the first or second hop of the Physical Uplink Control Channel (PUCCH) (e.g., the index of the starting RB), the start position of the Physical Random Access Channel (PRACH), the start position of the Channel State Information Reference Signal (CSI-RS), the start position of the Physical Downlink Control Channel (PDCCH), and the start position of measurement resources. Frequency domain bandwidth includes at least one of the following: the bandwidth of the CSI-RS and the bandwidth of the measurement resources.

[0169] In some embodiments, the first signaling indicates the carrier bandwidth, frequency domain start position, or frequency domain bandwidth, and the second signaling also indicates the carrier bandwidth, frequency domain start position, or frequency domain bandwidth. In some cases, the base station sends the first signaling and the second signaling to the UE. The carrier bandwidth, frequency domain start position, or frequency domain bandwidth indicated by the first signaling is less than or equal to a first threshold, and the carrier bandwidth, frequency domain start position, or frequency domain bandwidth indicated by the second signaling is greater than the first threshold. Alternatively, the first signaling may indicate that the system carrier is not within a specific frequency range (or within a first specific frequency range), and the second signaling may indicate that the system carrier is within a specific frequency range (or within a second specific frequency range). The UE receives the first signaling and the second signaling, and determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth according to the indication of the second signaling; the UE ignores the indication content of the first signaling. Taking the carrier bandwidth as an example, the first threshold may be 275 RBs, the first signaling may indicate a carrier bandwidth of 1-275 RBs, and the second signaling may indicate a carrier bandwidth of 276-555 RBs. When the carrier bandwidth is less than or equal to 275 RBs, the base station uses first signaling to indicate the carrier bandwidth; when the carrier bandwidth is greater than 275 RBs, the base station uses second signaling to indicate the carrier bandwidth. If the UE receives a first signaling indicating a bandwidth of 200 RBs and a second signaling indicating a bandwidth of 347 RBs, the UE determines the indicated bandwidth to be 347 RBs. In other cases, the carrier bandwidth, frequency domain start position, or frequency domain bandwidth indicated by the second signaling can be any value, such as greater than, equal to, or less than a first threshold. The UE receives both the first and second signaling, and determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth based on the indication of the second signaling, ignoring the indication of the first signaling. Again, taking carrier bandwidth as an example, if the UE receives a first signaling indicating a bandwidth of 200 RBs and a second signaling indicating a bandwidth of 180 RBs, the UE determines the indicated bandwidth to be 180 RBs. In some cases, the base station sends second signaling to the UE, the UE receives the second signaling, and the UE determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth based on the indication of the second signaling.

[0170] In some embodiments, a first signaling instruction indicates a carrier bandwidth, a frequency domain start position, or a frequency domain bandwidth. A second signaling instruction indicates how to interpret the value indicated by the first signaling instruction. The UE receives the first and second signaling instructions. The UE determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth based on the indications of the first and second signaling instructions. In some cases, the first signaling instruction may indicate multiple configurations. Specifically, the first signaling instruction may indicate multiple carrier bandwidths, or multiple frequency domain start positions, or multiple frequency domain bandwidths (i.e., multiple candidate configurations). The carrier bandwidth, or frequency domain start position, or frequency domain bandwidth indicated by the second signaling instruction is at least one of the multiple carrier bandwidths, or multiple frequency domain start positions, or multiple frequency domain bandwidths (e.g., which one of the multiple candidate configurations). In some cases, the differences between the multiple candidate configuration values ​​are the same. In some cases, one of the multiple candidate configuration values ​​is a default value. In the absence of a second signaling instruction, the carrier bandwidth, frequency domain start position, or frequency domain bandwidth indicated by the first signaling instruction is a default value. Still taking carrier bandwidth as an example, the first signaling instruction or the indication information of the first signaling instruction contains 9 bits. Each information bit value or each valid information bit value may indicate two carrier bandwidths. As shown in Table 1, the information bit '000000000' in the first signaling can indicate a carrier bandwidth of 1 RB and 276 RBs; the information bit '000000001' in the first signaling can indicate a carrier bandwidth of 2 RBs and 277 RBs; and the information bit '000000010' in the first signaling can indicate a carrier bandwidth of 3 RBs and 278 RBs. Similarly, the information bit '100010010' in the first signaling can indicate a carrier bandwidth of 275 RBs and 550 RBs. Furthermore, the second signaling indicates which carrier bandwidth the first signaling refers to. The second signaling contains 1 bit, where bit '0' represents carrier bandwidth 1, which is the first carrier bandwidth indicated by the first signaling, and bit '1' represents carrier bandwidth 2, which is the second carrier bandwidth indicated by the first signaling. For example, if the UE receives a first signaling message containing bits '000000010', it indicates that the carrier bandwidth is 3 RBs or 278 RBs. If the UE receives a second signaling message containing bits '0', then the UE determines that the indicated carrier bandwidth is 3 RBs. Alternatively, if the UE receives a first signaling message containing bits '000000010', it indicates that the carrier bandwidth is 3 RBs or 278 RBs. If the UE receives a second signaling message containing bits '1', then the UE determines that the indicated carrier bandwidth is 278 RBs. Further, carrier bandwidth 1 is the default value. If there is no second signaling message, then the carrier bandwidth indicated by the first signaling message is the value of carrier bandwidth 1 in Table 1.

[0172] The first signaling value is: Carrier bandwidth 1; Carrier bandwidth 2000000000127600000000122770000000103278…100010000273548100010001274549100010010275550 surface

[0173] In some embodiments, the first signaling indicates a first carrier bandwidth, or a first frequency domain start position, or a first frequency domain bandwidth. The second signaling indicates whether a mathematical operation is performed on the first carrier bandwidth, or the first frequency domain start position, or the size of the first frequency domain bandwidth, or how the mathematical operation is performed. In some cases, the presence or absence of the second signaling indicates whether a mathematical operation is performed. For example, the presence of the second signaling indicates that a mathematical operation is performed, and the absence of the second signaling indicates that no mathematical operation is performed. If the second signaling indicates that no mathematical operation is performed on the first carrier bandwidth, or the first frequency domain start position, or the size of the first frequency domain bandwidth, the UE determines that the carrier bandwidth is the indicated first carrier bandwidth, or the frequency domain start position is the first frequency domain start position, or the frequency domain bandwidth is the first frequency domain bandwidth. If the second signaling indicates that a mathematical operation is performed on the first carrier bandwidth, or the first frequency domain start position, or the first frequency domain bandwidth, then the carrier bandwidth, or the frequency domain start position, or the size of the frequency domain bandwidth is the value after performing the mathematical operation on the first carrier bandwidth, or the first frequency domain start position, or the first frequency domain bandwidth. In some cases, mathematical operations include addition, such as adding a specific value to the first carrier bandwidth, the first frequency domain start position, or the size of the first frequency domain bandwidth. The specific value is a positive number greater than 1, i.e., a set integer value. This specific value is predefined by the protocol or indicated by a second signaling. Continuing with Table 1 as an example, the range of the first carrier bandwidth indicated by the first signaling is 1, 2, 3, ..., 275, and we assume the specific value is 275. For example, if the first signaling indicates a first carrier bandwidth of 270 RBs, without second signaling, it means the carrier bandwidth is 270 RBs; if the second signaling indicates a mathematical operation, it means the carrier bandwidth is 545 RBs (i.e., 270 + 275). In some cases, data operations include multiplication, such as multiplying the first carrier bandwidth, the first frequency domain start position, or the size of the first frequency domain bandwidth by a specific value. This specific value is predefined by the protocol or indicated by a second signaling. The specific value is a positive number greater than 1. Continuing with Table 1 as an example, we assume the specific value is 2. For example, the first signaling indicates that the first carrier bandwidth is 270 RBs. If there is no second signaling, then it means that the carrier bandwidth is 270 RBs. If the second signaling indicates that a mathematical operation is performed, then it means that the carrier bandwidth is 540 RBs (i.e., 270*2).

[0174] In some embodiments, the second signaling indicates the carrier bandwidth, frequency domain start position, or frequency domain bandwidth. In other words, the second signaling is another first signaling. The UE determines the carrier bandwidth, frequency domain start position, or frequency domain bandwidth based on the first and second signaling. The size of the carrier bandwidth, frequency domain start position, or frequency domain bandwidth determined by the UE is the sum of the carrier bandwidths indicated by the first and second signaling, or the sum of the frequency domain start positions, or the sum of the frequency domain bandwidths. Taking carrier bandwidth as an example again, if the carrier bandwidth indicated by the first signaling is 200 RBs and the carrier bandwidth indicated by the second signaling is 136 RBs, then the UE determines the carrier bandwidth to be 336 RBs (i.e., 200 + 136).

[0175] This embodiment determines resource configuration by adding a second signaling signal, or by using the first and second signaling signals in combination. This allows for UE configuration when the wireless system supports a larger bandwidth. The first signaling signal can be retained, achieving compatibility with the existing network and not affecting the UEs and configurations in the existing network.

[0176] Example 2

[0177] This embodiment describes the process of resource configuration when resource configuration includes frequency domain start position configuration and frequency domain bandwidth configuration.

[0178] In some embodiments, the first signaling or the second signaling indicates the frequency domain start position and frequency domain bandwidth. The frequency domain start position and frequency domain bandwidth are the frequency domain start position and bandwidth of the Bandwidth Part (BWP) (i.e., a portion of the carrier bandwidth), or the frequency domain start position and bandwidth used for uplink cancellation indication, or the frequency domain start position and bandwidth of the uplink subband, or the frequency domain start position and bandwidth of the Common Frequency Range (CFR). The CFR is used for PDCCH or PDSCH transmission in broadcast or multicast services. The uplink subband is used for transmission of uplink signals on downlink or Orthogonal Frequency Division Multiplexing (OFDM) symbols in Sub-Band Full Duplex (SBFD). In some cases, the frequency domain bandwidth assumption is used to determine the indicated frequency domain start position and frequency domain bandwidth. The frequency domain start position and frequency domain bandwidth can be indicated by a Resource Indicator Value (RIV). The determination of RIV can be expressed by the following formula.

[0179]

[0180] Where, N assAssuming a frequency domain bandwidth, L represents the number of RBs, RBGs, REs, or REGs. fre The indicated frequency domain bandwidth is represented by the number of RB, RBG, RE, or REG, N. start This indicates the starting position of the frequency domain, that is, the index of the first RB, RBG, RE, or REG of the indicated frequency domain resource. In some cases, the index of RB, RBG, RE, or REG starts from 0, L fre Cannot be greater than (N) ass -N start Based on a specific frequency domain bandwidth assumption, according to the formula above, a RIV value can determine a unique frequency domain start position and frequency domain bandwidth. Conversely, a frequency domain start position and frequency domain bandwidth can determine a unique RIV value. The frequency domain start position and frequency domain bandwidth indicated by the first signaling, or the resource indication value (RIV) of the first signaling, are determined using the first assumption (i.e., the first frequency domain bandwidth assumption). The frequency domain start position and frequency domain bandwidth indicated by the second signaling, or the resource indication value (RIV) of the second signaling, are determined using the second assumption (i.e., the second frequency domain bandwidth assumption). Further, the second assumption is greater than the first assumption. Similar to the above embodiments, the frequency domain bandwidth indicated by the first signaling is less than or equal to a first threshold, and the frequency domain bandwidth indicated by the second signaling is greater than the first threshold. In some cases, the UE receives the first signaling, and the UE determines the frequency domain start position and frequency domain bandwidth according to the indication of the first signaling. In some cases, the UE receives both the first and second signaling, and the UE determines the frequency domain start position and frequency domain bandwidth according to the indication of the second signaling, ignoring the indication content of the first signaling.

[0181] In some embodiments, if the carrier bandwidth is less than or equal to a first threshold or the system carrier is not within a specific frequency range (or within a first specific frequency range), the frequency domain start position and frequency domain bandwidth indicated by the first or second signaling, or the resource indication value of the first or second signaling, are determined using a first assumption. If the carrier bandwidth is greater than the first threshold or the system carrier is within a specific frequency range (or within a second specific frequency range), the frequency domain start position and frequency domain bandwidth indicated by the first or second signaling, or the resource indication value of the first or second signaling, are determined using a second assumption. In some cases, the first threshold is the same as the value of the first assumption. In some cases, the first threshold is different from the value of the first assumption. On the UE side, the UE receives the first signaling and the second signaling, or the second signaling. The frequency domain start position and frequency domain bandwidth indicated by the second signaling, or the resource indication value of the first or second signaling, are determined using the second assumption.

[0182] In some embodiments, the first signaling indicates the first frequency domain start position and the first frequency domain bandwidth. Similar to Embodiment 1, the second signaling indicates whether to perform mathematical operations on the first frequency domain start position and the first frequency domain bandwidth, or how to perform mathematical operations on the first frequency domain start position and the first frequency domain bandwidth. If the second signaling indicates that no mathematical operations are performed on the first frequency domain start position and the first frequency domain bandwidth, then the frequency domain start position is the indicated first frequency domain start position, and the frequency domain bandwidth is the indicated first frequency domain bandwidth. If the second signaling indicates that mathematical operations are performed on the first frequency domain start position and the first frequency domain bandwidth, then the frequency domain start position is the frequency domain start position after data operations, and the frequency domain bandwidth is the frequency domain bandwidth after data operations. Similar to Embodiment 1, the mathematical operations include addition operations.

[0183] In some embodiments, a first signaling instruction indicates a first frequency domain start position and a first frequency domain bandwidth. A second signaling instruction indicates a second frequency domain start position and a second frequency domain bandwidth. The frequency domain resources are jointly determined by the first and second signaling instructions. The location of the frequency domain resources is the sum of the first frequency domain start position and the second frequency domain bandwidth.

[0184] This embodiment determines resource configuration by adding a second signaling signal, or by using a combination of the first and second signaling signals. This allows for UE configuration even when the wireless system supports a larger bandwidth. The retention of the first signaling signal ensures compatibility with the existing network and does not affect UEs or configurations within the current network. Furthermore, a single signaling signal simultaneously indicates the configuration of two types of resources—a joint indication—which saves signaling overhead.

[0185] Example 3

[0186] This embodiment describes the process of resource configuration, including rate matching resource configuration and channel state information (CSI) feedback subband configuration.

[0187] In some embodiments, the first signaling indicates a rate-matching resource or a CSI feedback subband. Specifically, the first signaling uses a bitmap to indicate this, where each bit in the bitmap corresponds to a rate-matching resource (RB) or a subband, and a subband contains one or more RBs. A bit value of '1' indicates that the corresponding RB is a rate-matching resource or that the corresponding subband has a CSI report. In other words, the UE reports the CSI of the subband with a bit value of '1'. A bit value of '0' indicates that the corresponding RB is not a rate-matching resource or that the corresponding subband does not have a CSI report. In other words, the UE does not report the CSI of the subband with a bit value of '0'. The second signaling indicates a rate-matching resource or a CSI feedback subband. In some cases, similar to the previous embodiments, the UE determines the rate-matching resource or CSI feedback subband based on the second signaling. In some cases, the UE determines the rate-matching resource or CSI feedback subband based on both the first and second signaling. The UE can concatenate the bitmap carried by the first signaling and the bitmap carried by the second signaling, and use the concatenated bitmap to indicate the rate-matching resource or CSI feedback subband. Furthermore, the bitmap carried by the second signaling is concatenated after or before the bitmap carried by the first signaling. For example, if the bitmap carried by the first signaling is '1000100' and the bitmap carried by the second signaling is '1101110', the concatenated bitmap is '10001001101110'.

[0188] In some cases, the number of RBs corresponding to each bit in the bitmap, or the number of RBs contained in a subband, depends on the carrier bandwidth or a portion of the bandwidth (i.e., a portion of the carrier bandwidth). Specifically, if the carrier bandwidth or a portion of the bandwidth is less than or equal to a second threshold, or the system carrier is not within a specific frequency range (or within a first specific frequency range), each bit corresponds to one RB. If the carrier bandwidth or a portion of the bandwidth is greater than the second threshold, or the system carrier is within a specific frequency range (or within a second specific frequency range), each bit corresponds to multiple RBs (e.g., two or three). In some cases, if the carrier bandwidth or a portion of the bandwidth is greater than the second threshold, or the system carrier is not within a specific frequency range (or within a first specific frequency range), the number of RBs contained in a subband is an integer multiple of the number of RBs contained in a subband if the carrier bandwidth or a portion of the bandwidth is less than or equal to the second threshold, or the system carrier is within a specific frequency range (or within a second specific frequency range). For example, the former is two times, three times, etc., the latter.

[0189] In some cases, the first signaling carries a first bit diagram, where each bit indicates a preset number of resources, which is indicated by the second signaling. For example, the second signaling might indicate that the preset number of resources is 1 RB or 2 RBs. The UE determines the rate matching resource configuration and channel state information (CSI) feedback subband configuration based on the first and second signaling.

[0190] This embodiment adds a second signaling signal and uses the first and second signaling signals together to determine resource configuration. This allows for UE configuration when the wireless system supports a larger bandwidth. The retention of the first signaling signaling ensures compatibility with the existing network and does not affect the UEs and configurations in the existing network.

[0191] Example 4

[0192] This embodiment describes the process of resource configuration when resource configuration includes reference signal configuration or frequency domain position configuration of DC components.

[0193] In some embodiments, the first signaling configures the bandwidth of the reference signal. The reference signal includes at least a Sounding Reference Signal (SRS). Further, the first signaling configures at least one of the following: the transmission bandwidth, the number of frequency hopping, and the transmission bandwidth per hop of the reference signal. When the carrier bandwidth or a portion thereof is less than or equal to a third threshold, or the system carrier is not within a specific frequency range (or within a first specific frequency range), the UE uses the transmission bandwidth, the number of frequency hopping, or the transmission bandwidth per hop of the reference signal configured by the first signaling. In some cases, when the carrier bandwidth or a portion thereof is greater than the third threshold, or the system carrier is within a specific frequency range (or within a second specific frequency range), the transmission bandwidth, the number of frequency hopping, or the transmission bandwidth per hop of the reference signal is the value configured by the first signaling multiplied by a specific integer. The specific integer is predefined by the protocol or indicated by the second signaling. Assuming the specific integer is 2, the UE multiplies the transmission bandwidth, the number of frequency hopping, or the transmission bandwidth per hop of the reference signal configured by the first signaling by 2, and uses the result of the multiplication as the transmission bandwidth, the number of frequency hopping, or the transmission bandwidth per hop of the reference signal. It is important to note that the starting point of the frequency domain resources of the reference signal (e.g., the initial RB) remains unchanged. For example, if the SRS transmission bandwidth configured in the first signaling is 128 RBs, the number of frequency hopping is 2, and the transmission bandwidth of each hop is 64 RBs, and the specific integer is 2, then the UE determines that the SRS transmission bandwidth is 256 RBs, the number of frequency hopping is 4, and the transmission bandwidth of each hop is 64 RBs, or the SRS transmission bandwidth is 256 RBs, the number of frequency hopping is 2, and the transmission bandwidth of each hop is 128 RBs.

[0194] In some cases, if the carrier bandwidth or a portion thereof exceeds a third threshold, or if the system carrier is within a specific frequency range (or a second specific frequency range), the reference signal is repeated in the frequency domain according to the transmission bandwidth, number of frequency hopping, or transmission bandwidth per hop configured by the first signaling. The repeated reference signal is continuous in the frequency domain, and the repeated reference signal is then transmitted. The number of repetitions is a specific integer, pre-defined by the protocol or indicated by the second signaling. Assuming a repetition count of 2, and based on the configuration of the first signaling, the transmission bandwidth of a certain hop is determined to be 64 RBs, with the initial RB being RB 0. Therefore, after repeating the reference signal, it occupies RBs 0-127, totaling 128 RBs, and the reference signal is transmitted on these occupied RBs.

[0195] In some embodiments, the first signaling or the second signaling indicates the frequency domain location of the DC component (or DC, or DC carrier). Specifically, the first signaling or the second signaling indicates a subcarrier index (or RE index), wherein the indicated subcarrier index is the frequency domain location of the DC component. In some embodiments, the UE receives the first signaling and determines that the subcarrier indicated by the first signaling is the frequency domain location of the carrier component. In some embodiments, the UE receives both the first and second signaling. The UE determines that the subcarrier indicated by the second signaling is the frequency domain location of the carrier component, and the UE ignores the content indicated by the first signaling. Optionally, a first specific value in the first or second signaling indicates that the DC component is outside the resource grid. Optionally, a second selected value in the first or second signaling indicates that the DC component is undetermined.

[0196] This embodiment determines resource configuration by adding a second signaling signal, or by using the first and second signaling signals in combination. This allows for UE configuration when the wireless system supports a larger bandwidth. The first signaling signal can be retained, achieving compatibility with the existing network and not affecting the UEs and configurations in the existing network.

[0197] Example 5

[0198] This embodiment describes the process of resource configuration, including PTRS configuration.

[0199] In some embodiments, the Phase Tracking Reference Signal (PTRS) occupies one or more REs in the frequency domain. The PTRS is transmitted along with the data channel. Two consecutive REs occupied by the PTRS are spaced apart in the frequency domain (i.e., the frequency domain spacing of the PTRS) by one or more REs or RBs. In some cases, one or more PTRS samples can be mapped onto an OFDM symbol. One or more PTRS samples can be divided into one or more groups (here referred to as PTRS groups), each group containing one or more PTRS samples. The frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group is related to the bandwidth of the data channel. One or more bandwidth thresholds are used to determine the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group. One or more bandwidth thresholds are configured by the base station. Table 2 shows the relationship between the PTRS frequency domain spacing, the number of PTRS groups, or the number of samples in a PTRS group and the data channel bandwidth. Taking the first row as an example, when the data channel bandwidth is greater than or equal to N... RB0 And less than N RB1 At this time, the number of PTRS groups is 2, the number of samples in each PTRS group is 2, and the absence of frequency domain interval indicates the absence of PTRS. N RB0 N RB1 N RB2 N RB3 、 or N RB4 This is the bandwidth threshold, and its value is configured by the base station. N RB This refers to the bandwidth of the data channel.

[0202] In some embodiments, the first signaling configures one or more bandwidth thresholds. In some embodiments, the second signaling configures one or more bandwidth thresholds. In some embodiments, the first signaling configures a portion of one or more bandwidth thresholds, and the second signaling configures another portion of one or more bandwidth thresholds. For example, in Table 2, the first signaling configures N RB0 N RB1 N RB2 The value of the second signaling configuration N RB3 、 or N RB4 The UE constructs a channel bandwidth interval based on the bandwidth thresholds configured in the first and second signaling. The channel bandwidth interval to which the data channel bandwidth belongs is used as the target bandwidth interval, and the configuration corresponding to the target bandwidth interval is used as the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in the PTRS group. In some embodiments, when the UE receives the second signaling, the UE only uses the bandwidth thresholds configured in the second signaling to determine the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in the PTRS group; the UE ignores the bandwidth thresholds configured in the first signaling.

[0203] In some embodiments, the first signaling configures one or more bandwidth thresholds. If the bandwidth of the data channel is less than or equal to a fourth threshold, the UE uses the bandwidth threshold configured in the first signaling to construct a channel bandwidth interval, and determines the frequency domain spacing of PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group based on the configuration of the channel bandwidth interval to which the data channel bandwidth belongs. If the bandwidth of the data channel is greater than the fourth threshold, the UE uses the result of multiplying the bandwidth threshold configured in the first signaling by a specific integer to construct a channel bandwidth interval, and determines the frequency domain spacing of PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group based on the configuration of the channel bandwidth interval to which the data channel bandwidth belongs. For example, N in Table 2 RB0 N RB1 N RB2 N RB3 N RB4 The bandwidth threshold configured for the first signaling is used. If the bandwidth of the data channel is greater than the fourth threshold, the UE uses the channel bandwidth range constructed in Table 3 to determine the frequency domain spacing of PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group. Assuming a specific integer is 2, the bandwidth threshold in Table 3 is twice the bandwidth threshold in Table 2.

[0204] Table 3

[0205]

[0206]

[0207] In some embodiments, if the bandwidth of the data channel is greater than a fourth threshold, the UE constructs a channel bandwidth interval using the bandwidth threshold configured in the first signaling. The UE reduces the data channel bandwidth by a specific integer multiple, and uses the reduced bandwidth to determine the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group. Assuming this specific integer is 2, the UE determines the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group based on the configuration of the channel bandwidth interval to which half of the data channel bandwidth belongs. Further, optionally, the determined frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group is multiplied by the specific integer, and the result of the multiplication is the frequency domain spacing of the PTRS of the data channel, the number of PTRS groups, or the number of PTRS samples in a PTRS group. Still based on the example in Table 2, if the bandwidth of the data channel is greater than the fourth threshold, the UE uses Table 4 to determine the frequency domain spacing of the PTRS, the number of PTRS groups, or the number of PTRS samples in a PTRS group. In Table 4, the specific integer is assumed to be 2. For example, the UE determines that the reduced data channel bandwidth is within the bandwidth range in the second row of Table 4. The UE determines that the frequency domain spacing of the PTRS is 2, the number of PTRS groups is 2, or the number of PTRS samples in the PTRS group is 4. Optionally, after multiplying the results, the UE determines that the frequency domain spacing of the PTRS used for the data channel is 4, the number of PTRS groups is 4, or the number of PTRS samples in the PTRS group is 8.

[0210] In some embodiments, if the bandwidth of the data channel is greater than a fourth threshold, as in other embodiments, the UE divides the data channel into multiple data sub-channels. The multiple data sub-channels determine their PTRS frequency domain spacing, number of PTRS groups, or number of samples in each PTRS group according to the method described in the above embodiments. It should be understood that different data sub-channels may have different PTRS frequency domain spacing, number of PTRS groups, or number of samples in each PTRS group. Dividing the data channel into a first data sub-channel and a second data sub-channel, the PTRS frequency domain spacing, number of PTRS groups, or number of samples in each PTRS group can be determined according to Table 2.

[0211] In some cases, the PTRS frequency domain spacing, the number of PTRS groups, or the number of samples in a PTRS group in the data channel are determined according to the first data sub-channel or the second data sub-channel.

[0212] This embodiment adds a second signaling signal and uses the first and second signaling signals together to determine resource configuration. This allows for UE configuration when the wireless system supports a larger bandwidth. The first signaling signal can be retained, achieving compatibility with the existing network and not affecting the UEs and configurations in the existing network.

[0213] Example 6

[0214] If the bandwidth of the data channel is too large, more efficient transmission can be achieved through configuration. This embodiment describes the transmission configuration of the data channel.

[0215] In some embodiments, the base station sends one or more PDSCHs to the UE. The UE sends one or more PUSCHs to the base station. PUSCHs and PDSCHs are collectively referred to as data channels. A data channel can carry one or more Transport Blocks (TBs). The number of TBs carried by a data channel depends at least on the bandwidth of the data channel (or the number of Restricted Blocks (RBs) it contains). In some cases, when the number of RBs in the data channel is less than or equal to a fifth threshold, the data channel carries one TB. In some cases, when the number of RBs in the data channel is greater than the fifth threshold, the data channel carries multiple TBs, such as two TBs. The following description uses two TBs as an example; this method can also be used when the data channel carries more than two TBs. The data channel is divided into two parts, namely a first data sub-channel and a second data sub-channel. Specifically, the data channel is divided into two parts in the frequency domain, with the first data sub-channel and the second sub-data channel each occupying a portion. The first data sub-channel or the second data sub-channel occupies the low-frequency portion of the data channel (e.g., the portion with a smaller RB index), and the other occupies the high-frequency portion of the data channel (e.g., the portion with a larger RB index). The first data sub-channel and the second data sub-channel have the same time-domain resources. The first and second data sub-channels each carry one TB (Transmission Block), meaning one TB is mapped to the first data sub-channel and the other TB is mapped to the second data sub-channel. In some cases, the frequency domain resources of the first and second data sub-channels are half of the original data channel's frequency domain resources. In some cases, the number of RBs (Resource Blocks) occupied by the first data channel is... The number of RBs occupied by the second data channel is In some cases, the number of bits contained in a TB is determined based on the resources of the data channel to which it is mapped. For example, if the first TB is mapped to a first data sub-channel, the number of bits contained in that TB is determined based on the resources of the first data sub-channel. If the second TB is mapped to a second data sub-channel, the number of bits contained in that TB is determined based on the resources of the second data sub-channel.

[0216] A data channel can carry one (or transport) layer or multiple layers of data. In some cases, the number of data layers carried by a data channel is less than or equal to the sixth threshold, and the data channel carries one TB. In other cases, the number of data layers carried by a data channel is greater than the sixth threshold, and the data channel carries multiple TBs. Taking two TBs as an example, the first TB contains the first few layers of data, and the second TB contains the last few layers of data.

[0217] The data channel is scheduled by control information (such as DCI), which indicates at least one of the following for each TB: Modulation and Coding Scheme (MCS), New Data Indicator (NDI), and Redundancy Version (RV). The control information includes an MCS field to indicate the MCS, an NDI field to indicate the NDI, and an RV field to indicate the RV. Specifically, the control information may contain one or more MCS fields, one or more NDI fields, and one or more RV fields. The number of MCS fields, NDI fields, or RV fields included in the control information depends on the number of TBs carried by the data channel. In some cases, the number of MCS fields, NDI fields, or RV fields included in the control information is the same as the number of TBs carried by the data channel, or depends on at least one of the bandwidth of the data channel and the number of data layers carried by the data channel. If the number of RBs in a data channel is less than or equal to the fifth threshold and / or the number of data layers carried by the data channel is less than or equal to the sixth threshold, the control information includes one MCS field, one NDI field, or one RV field. If the number of RBs in a data channel is greater than the fifth threshold and / or the number of data layers carried by the data channel is greater than the sixth threshold, the control information includes multiple MCS fields, multiple NDI fields, or multiple RV fields. Each of the multiple MCS fields, multiple NDI fields, or multiple RV fields indicates one TB of MCS, NDI, or RV. The indication order is as follows: first, the TBs of different layers of the same data subchannel are indicated, and then the TBs of different data subchannels are indicated. That is, these multiple fields first indicate all the TBs of different layers of the first data subchannel, and then indicate the TBs of different layers of the next data subchannel, and so on. Alternatively, the indication order is as follows: first, the TBs of different data subchannels on the same layer are indicated, and then the TBs of different layers are indicated. That is, these multiple fields first indicate all the TBs of all data subchannels in the first layer, and then indicate the TBs of all data subchannels in the next layer, and so on.

[0218] In some cases, the number of MCS fields, NDI fields, or RV fields included in the control information is the same as the maximum number of TBs carried by the data channel. When the number of TBs carried by the data channel is less than the maximum number, the values ​​of one or more MCS fields, NDI fields, or RV fields are default values ​​or reserved.

[0219] Figure 3 is an example diagram of a data channel partitioning method provided in an embodiment of this application. The PDSCH contains 300 RBs in the frequency domain. Its fifth threshold is 275 RBs. Therefore, the PDSCH is divided into two PDSCHs, PDSCH 1 and PDSCH 2. Each PDSCH 1 and PDSCH 2 contains 150 RBs. In one embodiment, regardless of the number of layers the data carried by the PDSCH contains, PDSCH 1 carries one TB, and PDSCH 2 carries one TB. The PDSCH carries a total of 2 TB. In one embodiment, the data carried by the PDSCH contains 3 layers. Then PDSCH 1 carries one TB, and PDSCH 2 carries one TB. The PDSCH carries a total of 2 TB. The control information contains two MCS fields, NDI fields, or RV fields. The first MCS field, NDI field, or RV field indicates the MCS, NDI, or RV of the first TB, respectively. The second MCS field, NDI field, or RV field indicates the MCS, NDI, or RV of the second TB, respectively.

[0220] In one embodiment, the data carried by the PDSCH comprises 5 layers. PDSCH 1 carries 2 TBs, with the first TB containing 2 layers of data and the second TB containing 3 layers of data. PDSCH 2 carries 2 TBs, with the first TB containing 2 layers of data and the second TB containing 3 layers of data. The PDSCH carries a total of 4 TBs.

[0221] Example 7

[0222] This example describes the application configuration of uplink silent resources in PUSCH.

[0223] In some embodiments, the UE sends one or more PUSCHs to the base station. The PUSCH resources may contain one or more reserved resources. Reserved resources are also called uplink silence resources. Uplink silence may be applied to PUSCH transmissions. In some cases, uplink silence is applied to PUSCH transmissions. The modulation symbols of the PUSCH are not mapped to reserved resources. When mapping the modulation symbols of the PUSCH to PUSCH resources, the UE skips the reserved resources. That is, the modulation symbols of the PUSCH are mapped to PUSCH resources with at least the reserved resources removed. In some cases, uplink silence is not applied to PUSCH transmissions. The modulation symbols of the PUSCH are mapped to PUSCH resources, including reserved resources.

[0224] OFDM symbols include SBFD symbols and non-SBFD symbols. Uplink subbands reside on SBFD symbols. In some cases, the base station configures uplink silence to apply to PUSCH transmitted on SBFD symbols, or to PUSCH transmitted on non-SBFD symbols, or to PUSCH transmitted on any symbol. The base station uses RRC signaling or MAC CE to perform this configuration. In some cases, the DCI indicates whether uplink silence is enabled. If the DCI indicates enabled, uplink silence applies to its scheduled or active PUSCH; if the DCI indicates disabled, uplink silence does not apply to its scheduled or active PUSCH. For a single PUSCH transmission scheduled by the DCI, the UE determines whether to apply uplink silence to the PUSCH based on the DCI indication.

[0225] For DCI-scheduled multiple PUSCH transmissions, or DCI-scheduled PUSCHs with duplicates, or configured-granted PUSCHs, the UE determines whether to apply uplink silence to the PUSCHs based on the configuration of RRC signaling or MAC CE. Further, DCI schedules or activates multiple PUSCH transmissions, or transmissions with duplicates. If DCI indicates uplink silence is disabled, then none of the DCI-scheduled or activated multiple PUSCH transmissions, or transmissions with duplicates, will apply uplink silence. Similarly, if configured-granted PUSCHs are configured not to apply uplink silence, then configured-granted PUSCHs will not apply uplink silence. If DCI indicates uplink silence is enabled, the UE applies uplink silence to PUSCHs transmitted on SBFD symbols, or to PUSCHs transmitted on non-SBFD symbols, or to PUSCHs transmitted on any symbol, based on the configuration of RRC signaling or MAC CE. Similarly, if a licensed PUSCH is configured to apply uplink silence, the UE applies the uplink silence to PUSCH transmitted on SBFD symbols, or to PUSCH transmitted on non-SBFD symbols, or to PUSCH transmitted on any symbol, depending on the configuration of the RRC signaling or MAC CE. In some cases, the base station configures uplink silence to apply to PUSCH transmitted on SBFD symbols. For multiple PUSCH transmissions scheduled or activated by DCI, or with duplicate PUSCH transmissions, or with licensed PUSCH configured, the UE applies uplink silence only to PUSCH transmitted on SBFD symbols. The UE does not apply uplink silence to PUSCH transmitted on non-SBFD symbols. In some cases, the base station configures uplink silence to apply to PUSCH transmitted on non-SBFD symbols. For multiple PUSCH transmissions scheduled or activated by DCI, or with duplicate PUSCH transmissions, or with licensed PUSCH configured, the UE applies uplink silence only to PUSCH transmitted on non-SBFD symbols. The UE does not apply uplink silence to PUSCH transmitted on SBFD symbols. In some cases, the base station configures uplink silence to apply to PUSCH transmitted on any symbol. For multiple PUSCH transmissions scheduled or activated by DCI, or with duplicate PUSCH transmissions, or with configured licensed PUSCH, the UE applies uplink silence only to arbitrary PUSCH.

[0226] In some cases, uplink silence applies to PUSCH transmissions. In this case, the PUSCH resource contains one or more reserved resources. In other cases, uplink silence does not apply to PUSCH transmissions. In this case, the PUSCH resource does not contain reserved resources. That is, the UE determines whether there are reserved resources on the PUSCH resource based on the configuration or DCI indication.

[0227] This configuration allows for flexible indication of uplink silence applied to PUSCH transmissions on different OFDM symbol types.
