It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0025] The uplink transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0026] As shown in FIG2 , an embodiment of the present application provides an uplink transmission method 200 , which can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0027] S202: The terminal performs a first operation, where the first operation includes at least one of the following two: when the terminal is configured or enabled with uplink muting (UL muting), determining, based on information of the first uplink transmission, whether the first uplink transmission performs uplink muting; and when uplink muting and first uplink control information (UCI) are multiplexed in the first uplink transmission, multiplexing the first UCI on the first uplink transmission based on resources for uplink muting in the first uplink transmission.

[0028] In one embodiment, the network side device can determine whether to enable the terminal to perform uplink silence based on the terminal capability report. For example, when the terminal reports that it has the ability to perform uplink silence, the network side device can enable the terminal to perform uplink silence. At the same time, the network side device can also configure or indicate to the terminal the time domain resources and frequency domain resources for uplink silence, for example, the period of uplink silence and the offset within the period in the time domain, as well as the symbol position in the time slot, for example, one or more continuous or discontinuous symbols, and the resource element (RE) or resource block (RB) position of uplink silence in the frequency domain, for example, the RE or RB of silence in the frequency domain is in a comb structure, such as the base station configures a comb structure index (comb index) to indicate the position of the RE or RB of silence in the frequency domain.

[0029] In various embodiments of the present application, when uplink silence is performed during the first uplink transmission, the terminal does not map the complex-valued symbols corresponding to the first uplink transmission to the virtual resource block (VRB) on the RE or RB corresponding to the uplink silence.

[0030] The first uplink transmission mentioned in various embodiments of the present application may be a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a physical uplink control channel (Physical Uplink Control Channel, PUCCH), etc. Optionally, the first uplink transmission is PUSCH.

[0031] The information of the first uplink transmission may be information related to the first uplink transmission. In one embodiment, the information of the first uplink transmission includes at least one of the following:

[0032] 1) The waveform corresponding to the first uplink transmission includes, for example, a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform, a Discrete Fourier Transform-Spread-OFDM (DFT-S-OFDM) waveform, and the like.

[0033] In one example, when the waveform corresponding to the first uplink transmission is a CP-OFDM waveform, the first uplink transmission supports uplink silence, that is, the first uplink transmission can perform uplink silence, and the subsequent ones are similar; when the waveform corresponding to the first uplink transmission is not a CP-OFDM waveform or the corresponding waveform is a DFT-S-OFDM waveform, the first uplink transmission does not support uplink silence, that is, the first uplink transmission does not perform uplink silence, and the subsequent ones are similar.

[0034] This example mainly considers that performing uplink silence during the first uplink transmission will increase the Peak to Average Power Ratio (PAPR) of the first uplink transmission, affecting the transmission power, etc. This impact is more serious under the DFT-S-OFDM waveform. This embodiment is beneficial to avoid increasing the PAPR of the first uplink transmission, avoiding affecting the transmission power, and improving the transmission performance of the first uplink transmission.

[0035] 2) Whether transform precoding of the first uplink transmission is enabled.

[0036] In an example, when transmission precoding of the first uplink transmission is not enabled, the first uplink transmission supports uplink muting; when transmission precoding of the first uplink transmission is enabled, the first uplink transmission does not support uplink muting.

[0037] This example mainly considers that performing uplink silence during the first uplink transmission will increase the PAPR of the first uplink transmission, affect the transmission power, etc. This impact is more serious when the transmission precoding of the first uplink transmission is enabled. This embodiment is beneficial to avoid increasing the PAPR of the first uplink transmission, avoid affecting the transmission power, and improve the transmission performance of the first uplink transmission.

[0038] 3) The scheduling type corresponding to the first uplink transmission, which includes, for example, dynamic scheduling, configuration authorization, etc.

[0039] In one example, when the scheduling type of the first uplink transmission is dynamic scheduling, the first uplink transmission supports uplink silence; when the scheduling type of the first uplink transmission is not dynamic scheduling (ie, configuration authorization), the first uplink transmission does not support uplink silence.

[0040] This example mainly considers the impact of the transport block size (TBS) determination process. If the uplink silent REs are not considered when determining the TBS, for the first dynamically scheduled uplink transmission, the transmission performance of the first uplink transmission (such as PUSCH) can be guaranteed by indicating a modulation and coding scheme (MCS), which corresponds to a lower modulation order or code rate, or by indicating a higher transmit power. However, the transmission performance of the first uplink transmission with authorization is usually not guaranteed.

[0041] Optionally, the scheduling type of the first uplink transmission is dynamic scheduling; wherein the modulation order or code rate corresponding to the MCS indicated by the scheduling signaling of the first uplink transmission is lower than a first threshold; or the transmission power indicated by the scheduling signaling of the first uplink transmission is higher than a second threshold. This example is conducive to ensuring the transmission performance of the first uplink transmission (such as PUSCH).

[0042] In another example, when the scheduling type of the first uplink transmission is configuration authorization, the first uplink transmission supports uplink silence; when the scheduling type of the first uplink transmission is not configuration authorization (ie, dynamic scheduling), the first uplink transmission does not support uplink silence.

[0043] For the dynamically scheduled first uplink transmission, the network side device scheduling can avoid the first uplink transmission and the uplink muting resource overlap, that is, transparent uplink muting (transparent UL muting). However, for the first uplink transmission with configuration authorization, it cannot be guaranteed that the first uplink transmission and the uplink muting resource do not overlap.

[0044] 4) A Radio Network Temporary Identity (RNTI) corresponding to the scheduling downlink control information (DCI) corresponding to the first uplink transmission.

[0045] In one example, when the RNTI corresponding to the scheduling DCI corresponding to the first uplink transmission is a cell radio network temporary identifier (C-RNTI), a configuration scheduling radio network temporary identifier (CS-RNTI) or a modulation and coding strategy radio network temporary identifier (MCS-C-RNTI), the first uplink transmission supports uplink silence; when the RNTI corresponding to the scheduling DCI corresponding to the first uplink transmission is other RNTIs, such as a temporary cell radio network temporary identifier (TC-RNTI), the first uplink transmission does not support uplink silence.

[0046] 5) Whether the first uplink transmission is scheduled by a random access response uplink grant (RAR UL grant).

[0047] In an example, when the first uplink transmission is not scheduled by the RAR-UL grant, the first uplink transmission supports uplink muting; when the first uplink transmission is scheduled by the RAR-UL grant, the first uplink transmission does not support uplink muting.

[0048] In some embodiments, the first uplink transmission is a PUSCH. The PUSCH in the Random Access Channel (RACH) process includes, for example: Msg3 PUSCH and its retransmission PUSCH; MsgA PUSCH and its retransmission.

[0049] 6) Whether the TB carried in the first uplink transmission is an initial transmission TB.

[0050] In one example, when the TB carried on the first uplink transmission is an initial transmission TB, the first uplink transmission supports uplink silence, wherein the terminal can determine whether the TB transmitted on the first uplink transmission is an initial transmission TB or a retransmission TB through the HARQ process corresponding to the first uplink transmission and the corresponding new data indicator (NDI); when the TB carried on the first uplink transmission is not an initial transmission TB (that is, a retransmission TB), the first uplink transmission does not support uplink silence.

[0051] This example mainly considers that when a TB is retransmitted, the TB size is the same as the initial TB, and rate matching cannot be performed based on the resources occupied by uplink silence, which may affect the performance of the first uplink transmission. This embodiment is conducive to improving the transmission performance of the first uplink transmission.

[0052] 7) Whether the first uplink transmission carries UCI or the type of the carried UCI, where the type of UCI includes, for example, low-priority UCI, high-priority UCI, etc.

[0053] The priorities mentioned in various embodiments of the present application may be physical layer priorities, for example, using a priority index to represent the priority, where priority index 0 corresponds to low priority and priority index 1 corresponds to high priority. Each PUCCH, PUSCH, or UCI corresponds to a priority index.

[0054] In one example, when the first uplink transmission does not carry UCI or the UCI carried by the first uplink transmission only includes the second UCI, the first uplink transmission supports uplink silence; when the first uplink transmission carries UCI or the UCI carried by the first uplink transmission is not the second UCI, the first uplink transmission does not support uplink silence.

[0055] Optionally, the second UCI may be predefined, for example, agreed upon by a protocol.

[0056] Optionally, the second UCI includes at least one of the following:

[0057] a: Low priority UCI.

[0058] b: UCI other than hybrid automatic repeat request Acknowledgement (HARQ-ACK), such as channel state information (CSI), configured grant uplink control information (CG-UCI), and uplink control information for unused transmission opportunity (Uplink Control Information for Unused Transmission Occasion, UTO-UCI).

[0059] c: UCI other than HARQ-ACK, CG-UCI, and UTO-UCI, such as CSI.

[0060] d: CSI, such as periodic CSI (P-CSI), semi-persistent CSI (SP-CSI), and aperiodic CSI (AP-CSI).

[0061] 8) The priority corresponding to the first uplink transmission.

[0062] In one example, when the first uplink transmission corresponds to a first priority (such as low priority), the first uplink transmission supports uplink silencing; when the first uplink transmission corresponds to a second priority (such as high priority), the first uplink transmission does not support uplink silencing, and the first priority is lower than the second priority.

[0063] This example mainly considers that performing uplink silence during the first uplink transmission will affect the performance of the first uplink transmission. This solution can protect the transmission of high-priority channels.

[0064] 9) Whether the first uplink transmission overlaps with the first uplink silent resource.

[0065] In an example, when the first uplink transmission overlaps with the first uplink silence resource, the first uplink transmission supports uplink silence; when the first uplink transmission does not overlap with the first uplink silence resource, the first uplink transmission does not support uplink silence.

[0066] 10) Whether the symbols overlapping the first uplink transmission and the first uplink silent resource include demodulation reference signal (DMRS) symbols.

[0067] In one example, when the symbols overlapping with the resources for uplink silence of the first uplink transmission do not include DMRS symbols, the first uplink transmission supports uplink silence; when the symbols overlapping with the resources for uplink silence of the first uplink transmission include DMRS symbols, the first uplink transmission does not support uplink silence.

[0068] 11) Whether the REs or RBs overlapping with the first uplink transmission and the first uplink silent resources include DMRS REs or RBs.

[0069] In one example, when the RE or RB overlapping with the first uplink silence resource of the first uplink transmission does not include DMRS RE or RB, the first uplink transmission supports uplink silence; when the RE or RB overlapping with the first uplink silence resource of the first uplink transmission includes DMRS RE or RB, the first uplink transmission does not support uplink silence.

[0070] 12) Whether the REs or RBs where the first uplink transmission overlaps with the first uplink silent resources include Phase Tracking Reference Signal (PTRS) REs or RBs.

[0071] In one example, when the RE or RB overlapping with the first uplink silence resource of the first uplink transmission does not include the PTRS RE or RB, the first uplink transmission supports uplink silence; when the RE or RB overlapping with the first uplink silence resource of the first uplink transmission includes the PTRS RE or RB, the first uplink transmission does not support uplink silence.

[0072] The first uplink silent resource mentioned in 9) to 12) above may be a first uplink silent resource configured or indicated by a network-side device.

[0073] S204: The terminal sends the first uplink transmission.

[0074] In the uplink transmission method provided in an embodiment of the present application, when the terminal is configured or enabled with uplink muting, the terminal determines whether to perform uplink muting on the first uplink transmission based on information of the first uplink transmission; when uplink muting and first UCI are multiplexed on the first uplink transmission, the first UCI can be multiplexed on the first uplink transmission based on the resources for uplink muting in the first uplink transmission, thereby achieving effective transmission of the first uplink transmission and improving the effectiveness and reliability of the communication system.

[0075] In one embodiment, determining, based on the information of the first uplink transmission, whether to perform uplink muting for the first uplink transmission includes: determining that the first uplink transmission performs uplink muting when at least one of the following conditions is met:

[0076] 1) The waveform corresponding to the first uplink transmission is a CP-OFDM waveform.

[0077] 2) Transmission precoding for the first uplink transmission is not enabled.

[0078] 3) The scheduling type of the first uplink transmission is dynamic scheduling.

[0079] 4) The RNTI corresponding to the scheduling DCI corresponding to the first uplink transmission is a cell radio network temporary identifier (C-RNTI), a configuration scheduling radio network temporary identifier (CS-RNTI), or a modulation and coding strategy radio network temporary identifier (MCS-C-RNTI) (a DCI with CRC scrambled by C-RNTI, CS-RNTI or MCS-C-RNTI)

[0080] 5) The first uplink transmission is not scheduled by a random access response uplink grant (RAR-UL grant). This example is beneficial for improving the transmission performance of the PUSCH (ie, the first uplink transmission) during the RACH process.

[0081] 6) The TB carried in the first uplink transmission is an initial transmission TB.

[0082] 7) The scheduling type of the first uplink transmission is configuration grant or semi-persistent scheduling (eg, PUSCH for SP-CSI report). Generally, 3) and 7) are not satisfied at the same time.

[0083] 8) The first uplink transmission does not carry UCI.

[0084] 9) The UCI carried in the first uplink transmission includes only second UCI. Optionally, the second UCI includes at least one of the following: low-priority UCI; UCI other than HARQ-ACK; UCI other than HARQ-ACK, CG-UCI, and UTO-UCI; or CSI.

[0085] 10) The first uplink transmission corresponds to a first priority, which may be a low priority. For example, the first priority corresponds to a physical layer priority, such as a priority index represented by a priority index, where priority index 0 corresponds to a low priority, priority index 1 corresponds to a high priority, and each PUCCH, PUSCH, or UCI corresponds to a priority index. For another example, the first priority corresponds to a logical channel priority LCH, and the first priority corresponds to an uplink transmission with a low priority LCH.

[0086] 11) The first uplink transmission overlaps with a first uplink silent resource, and the first uplink silent resource may include a time domain resource and a frequency domain resource.

[0087] 12) Symbols where the first uplink transmission overlaps with the first uplink silent resource do not include DMRS symbols.

[0088] 13) The REs or RBs where the first uplink transmission overlaps with the first uplink silent resources do not include DMRS REs or RBs.

[0089] 14) The REs or RBs where the first uplink transmission overlaps with the first uplink silent resources do not include PTRS REs or RBs.

[0090] In one embodiment, when uplink muting is enabled for a terminal, for a certain PUSCH transmission (i.e., the first uplink transmission), if its time domain resources overlap with the time domain resources for uplink muting, or both the time domain resources and the frequency domain resources overlap with the resources for uplink muting, and the OFDM symbol satisfying the uplink muting is not the symbol where the DMRS is located, or the RE for uplink muting is not the RE where the DMRS is located, and PUSCH transmission precoding is not enabled, then the terminal performs uplink muting when transmitting the PUSCH, that is, for the PUSCH transmission, when mapping the block of complex-valued symbols corresponding to the PUSCH to the virtual resource block (VRB), it cannot be mapped to the RE corresponding to the uplink muting.

[0091] In one embodiment, determining, based on the information of the first uplink transmission, whether to perform uplink muting for the first uplink transmission includes: determining that uplink muting is not to be performed for the first uplink transmission if at least one of the following conditions is met:

[0092] 1) The waveform corresponding to the first uplink transmission is not a CP-OFDM waveform or the corresponding waveform is a DFT-S-OFDM waveform.

[0093] 2) Transmission precoding for the first uplink transmission is enabled.

[0094] 3) The scheduling type of the first uplink transmission is not dynamic scheduling, for example, it may be configuration grant scheduling.

[0095] 4) The RNTI corresponding to the scheduling DCI corresponding to the first uplink transmission is TC-RNTI.

[0096] 5) The first uplink transmission is scheduled by the RAR-UL grant. This example is beneficial to improving the transmission performance of the PUSCH (ie, the first uplink transmission) during the RACH process.

[0097] 6) The scheduling type of the first uplink transmission is not configuration grant or semi-persistent scheduling, for example, it can be dynamic scheduling. Generally, 3) and 6) are not satisfied at the same time.

[0098] 7) The TB carried in the first uplink transmission is a retransmission TB. The determination of initial and retransmission of a TB is performed, for example, by determining whether a new date indicator (NDI) of a certain Hybrid Automatic Repeat Request (HARQ) identifier (ID) is flipped. If the NDI is flipped relative to the last scheduling, it indicates an initial transmission TB; otherwise, it indicates a retransmission TB.

[0099] 8) The first uplink transmission carries UCI.

[0100] 9) The UCI carried in the first uplink transmission does not satisfy the requirement of only the second UCI. For example, if the UCI carried in the first uplink transmission is only the second UCI, uplink muting is performed on the first uplink transmission. If the UCI carried in the first uplink transmission is only the first UCI, or if the UCI carried in the first uplink transmission is the first UCI and the second UCI is of different types, uplink muting is not performed on the first uplink transmission.

[0101] Optionally, the second UCI includes at least one of the following: low-priority UCI; UCI other than HARQ-ACK; UCI other than HARQ-ACK, CG-UCI and UTO-UCI; CSI.

[0102] 10) The first uplink transmission corresponds to a second priority, which may be a low priority.

[0103] 11) The first uplink transmission does not overlap with the first uplink silent resource. The uplink silent resource may include time domain resources and frequency domain resources.

[0104] 12) Symbols overlapped by the first uplink transmission and the first uplink silent resource include DMRS symbols;

[0105] 13) The REs or RBs where the first uplink transmission overlaps with the first uplink silent resource include DMRS REs or RBs;

[0106] 14) The REs or RBs where the first uplink transmission and the first uplink silent resources overlap include PTRS REs or RBs.

[0107] In one embodiment, the multiplexing of the first UCI on the first uplink transmission based on the uplink muting resource in the first uplink transmission includes at least one of the following:

[0108] 1) Determine the number of REs or RBs or symbols occupied by the first UCI in the first uplink transmission according to the number of REs or RBs or symbols occupied by uplink muting in the first uplink transmission.

[0109] In one embodiment, when determining the number of REs or symbols occupied by the first UCI in the first uplink transmission, the terminal determines the number of REs or RBs occupied by uplink muting in the first uplink transmission.

[0110] In other examples, when determining the number of REs or symbols occupied by the first UCI in the first uplink transmission, the terminal may not consider the number of REs or RBs occupied by uplink silence in the first uplink transmission, that is, it is not necessary to determine the number of REs or RBs or symbols occupied by the first UCI in the first uplink transmission based on the number of REs or RBs or symbols occupied by uplink silence in the first uplink transmission.

[0111] 2) Determine the RE or RB position to which the first UCI is mapped on the first uplink transmission by rate matching. For example, when mapping the first UCI on the first uplink transmission, it is not mapped to the RE or RB position occupied by uplink silence.

[0112] Optionally, the first UCI includes at least one of the following: HARQ-ACK, CG-UCI, UTO-UCI, CSI, channel state information part 1 (CSI part 1), and channel state information part 2 (CSI part 2). For example, a CSI report includes two parts, the first part is CSI part 1, which has a fixed number of bits and includes content such as RI, CRI, and CQI corresponding to the first codeword. The second part is CSI part 2, which has a variable number of bits and includes content such as PMI and CQI corresponding to the second codeword.

[0113] 3) When mapping the first UCI onto the first uplink transmission, it is not mapped onto REs, RBs, or symbols occupied by uplink silence.

[0114] For example, when mapping the first UCI to the first uplink transmission, it is not mapped to REs or RBs occupied by uplink silence. In this example, the first UCI may include at least one of the following: HARQ-ACK, CG-UCI, UTO-UCI, CSI, channel state information part 1 (CSI part 1), and channel state information part 2 (CSI part 2).

[0115] For example, when mapping the first UCI onto the first uplink transmission, it is not mapped onto symbols occupied by uplink silence. In this example, the first UCI may include at least one of the following: HARQ-ACK, CG-UCI, UTO-UCI, CSI, channel state information part 1 (CSI part 1), and channel state information part 2 (CSI part 2).

[0116] 4) Determine a RE position to which the first UCI is mapped on the first uplink transmission by using a puncturing method.

[0117] In this example, the first UCI may include at least one of the following: CSI, CSI part 1, and CSI part 2.

[0118] This embodiment is conducive to determining the number of REs or RE positions occupied by the first UCI, thereby improving the effectiveness and reliability of the communication system.

[0119] To explain in detail how the terminal multiplexes the first UCI on the first uplink transmission based on the uplink silence resources in the first uplink transmission, a specific embodiment will be described below.

[0120] The terminal may need to transmit the first UCI, such as HARQ-ACK, CG-UCI, UTO-UCI, or CSI, on the PUSCH (first uplink transmission). When the terminal transmits the first UCI on the PUSCH, the terminal first needs to determine the number of REs occupied by the first UCI when transmitted on the PUSCH, that is, the number of coded modulation symbols per layer when the first UCI is transmitted on the PUSCH. For a PUSCH that requires uplink muting, the terminal may adopt the following implementation method when determining the number of REs occupied by the first UCI when transmitted on the PUSCH or the number of coded modulation symbols per layer:

[0121] In one implementation manner, the terminal does not consider REs or RBs occupied by uplink silence. This implementation manner is simple to operate.

[0122] In another implementation, the terminal needs to determine the number of REs or RBs in which the PUSCH is uplink muted. For example, in OFDM symbol 1 transmitted by the PUSCH, the number of subcarriers available for transmitting the first UCI needs to be subtracted from the number of subcarriers occupied by uplink muting.

[0123] In another embodiment, the terminal needs to determine the number of uplink muted PUSCH symbols. For example, in OFDM symbol 1 transmitted by PUSCH, if the symbol overlaps with an uplink muted symbol, the number of subcarriers available for transmitting the first UCI is 0.

[0124] In addition, the terminal also needs to determine the RE position to which the first UCI is mapped when it is transmitted on the PUSCH. In the related art, for at least one of HARQ-ACK, CG-UCI and UTO-UCI, the mapping is backward mapping from the first non-DMRS symbol after the first DMRS symbol of the PUSCH. When mapping, it cannot be mapped to the RE where the PTRS is located, and the symbol where the DMRS is located. For CSI part 1 and CSI part 2, it is backward mapping from the first non-DMRS symbol of the PUSCH. When mapping, it cannot be mapped to the RE where the HARQ-ACK, CG-UCI, UTO-UC, PTRS is located, and the symbol where the DMRS is located. When the PUSCH needs to be uplink silenced, when determining the RE to which the first UCI is mapped when the PUSCH is transmitted, the following implementation method can be adopted:

[0125] In one implementation, the first UCI can be mapped to the RE where uplink muting occurs, using puncturing. Optionally, the power of the RE where uplink muting occurs is 0. That is, the RE position occupied by the first UCI is determined as if there is no uplink muting. That is, the first UCI can be mapped to the RE or RB corresponding to the uplink muting. However, the transmission power of the corresponding RE or RB is 0. In one implementation, the first UCI cannot be mapped to the RE or RB where uplink muting occurs. Rate matching can be used. When mapping the coded modulation symbols corresponding to the first UCI to the PUSCH, the terminal skips the RE, RB, or symbol corresponding to the uplink muting.

[0126] For example, for the first UCI (UCI1), when UCI1 is transmitted on a PUSCH with an uplink scheduling channel (UL-SCH), the terminal determines the number of bits of UCI1 according to the following formula, where the UCI1 may be at least one of HARQ-ACK, CG-UCI, UTO-UCI, and high-priority CSI part 1 (for example, when high-priority CSI is multiplexed on a low-priority PUSCH):

[0127] O UCI1 Indicates the number of UCI1 bits.

[0128] If O UCI1 ≥360, L UCI1 =11; otherwise, L UCI1 Indicates the number of CRC bits corresponding to UCI1.

[0129] Indicates the offset (betaoffset) corresponding to UCI1.

[0130] C UL-SCH Indicates the number of UL-SCH code blocks transmitted by PUSCH.

[0131] If the DCI format for scheduling PUSCH transmission contains the CBGTI field indicating that the terminal should not transmit the rth code block, then K r =0; otherwise K r is the rth code block size of the UL-SCH transmitted by PUSCH.

[0132] Indicates the bandwidth in which PUSCH transmission is scheduled, expressed in terms of a number of subcarriers.

[0133] Indicates the number of subcarriers in OFDM symbol 1 that carries PTRS in PUSCH transmission.

[0134] Indicates the number of resource elements in OFDM symbol 1 that can be used to transmit UCI1 in PUSCH transmission Indicates the total number of OFDM symbols for PUSCH, including all OFDM symbols used for DMRS.

[0135] In one embodiment, for any OFDM symbol carrying PUSCH DMRS, For any OFDM symbol that does not carry PUSCH DMRS,

[0136] In another embodiment, for any OFDM symbol carrying PUSCH DMRS or uplink silence, For any OFDM symbol that does not carry PUSCH DMRS and does not have uplink silence,

[0137] in, Indicates the number of subcarriers occupied by PTRS in OFDM symbol 1 during PUSCH transmission. Indicates the number of subcarriers occupied by uplink silence in OFDM symbol 1 during PUSCH transmission.

[0138] α represents the value of a higher layer parameter such as scaling.

[0139] l0 represents the index of the OFDM symbol where UCI1 starts mapping in PUSCH transmission. For example, for HARQ-ACK, CG-UCI, and UTO-UCI, it represents the symbol index of the first OFDM symbol that does not carry PUSCH DMRS after the first DMRS symbol.

[0140] For example, for UCI1, when UCI1 is transmitted on PUSCH without UL-SCH, the terminal determines the number of coded modulation symbols on each layer Q′ according to the following formula: UCI1 :

[0141] Wherein, R represents the PUSCH code rate.

[0142] Q m Indicates the modulation order of PUSCH.
