Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for transmitting wireless signals in non-terrestrial network communication systems. Background Technology

[0002] In existing NR (New Radio) systems, the DMRS (Demodulation Reference Signal) and PUCCH (Physical Uplink Control Channel) of PUSCH (Physical Uplink Shared Channel) support multiplexing of multiple antenna ports / multiple users through orthogonal sequences.

[0003] In December 2023, the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) #102 meeting decided to study the use of orthogonal sequences to support multiple users on PUSCH in the "Non-Terrestrial Network (NTN) for NR (New Radio)" work item (WI). In other words, multiple users need to transmit PUSCH with orthogonal code domains within the same time and frequency resources. This multiplexing technology can significantly improve uplink capacity and throughput. Summary of the Invention

[0004] After introducing the orthogonal sequence configuration of PUSCH, how to perform uplink power control is an important issue that needs to be considered; this application discloses a solution to the above problem. It should be noted that this application can be applied to various wireless communication scenarios, such as non-terrestrial network (NTN) communication scenarios and terrestrial network (TN) communication scenarios, and achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to non-terrestrial network communication scenarios and terrestrial network communication scenarios) can help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, the embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0190] As an example, when the first condition is valid, the application of the first TPC command is postponed; when the first condition is not valid, the application of the first TPC command is not postponed.

[0191] As an example, if the first condition is valid, the application of the first TPC command may be postponed; otherwise, the application of the first TPC command is not postponed.

[0192] As an example, "the first condition is valid" means that the first condition is met.

[0193] As an example, "the first condition is not valid" means that the first condition is not met.

[0194] As an example, the first condition is: the first symbol of the first PUSCH resource pool appears within a first duration after the last symbol of the PDCCH that received the first signaling;

[0195] The first duration depends on the SCS configuration.

[0196] As one embodiment, whether the application of the first TPC command is postponed depends on the temporal relationship between the first symbol of the first PUSCH resource pool and the last symbol of the PDCCH that receives the first signaling, including: whether the application of the first TPC command is postponed depends on whether a second condition is valid, the second condition depending on the symbol interval between the first symbol of the first PUSCH resource pool and the last symbol of the PDCCH that receives the first signaling.

Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for control plane 300 is illustrated using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the links between the first and second communication node devices and between the two UEs via PHY301. L2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and provides cross-area mobility support. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat Request). MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell.

L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS (Quality of Service) streams and data radio bearers (DRBs) to support service diversity.

[0239] Example 4

[0240] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0241] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0242] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0243] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), and M-Quadrature Amplitude Modulation (M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses an inverse Fast Fourier transform (IFFT). The multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream using an IFFT (Instantaneous Transformation) technique. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into an RF stream, which is then provided to different antennas 420.

[0244] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the second communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the first communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0245] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0246] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer function. The controller / processor 475 implements the L2 layer function. The controller / processor 475 may be associated with a memory 476 storing program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the second communication device 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0267] Example 5 illustrates a signal transmission flowchart according to an embodiment of this application, as shown in the attached diagram. Figure 5 As shown. In the appendix Figure 5 In this embodiment, terminal U1 and base station U2 communicate via an air interface. It should be noted that the order in this embodiment does not limit the signal transmission order or the order of implementation in this application.

[0268] Terminal U1 receives the first signaling in step S511 and sends the first signal in the first PUSCH resource pool in step S512.

[0269] Base station U2 sends a first signaling in step S521 and receives a first signal in the first PUSCH resource pool in step S522.

[0340] Example 9

[0341] Example 9 illustrates a schematic diagram of a first TPC command according to an embodiment of this application, as shown in the attached diagram. Figure 9 As shown.

[0342] In Example 9, the first TPC command indicates a first power offset, the unit of which is dB, and the first power offset is an accumulated value.

[0343] As an example, the first TPC command explicitly indicates the first power offset.

[0344] As an example, the first TPC command is mapped to the first power offset.

[0345] As an example, the mapping between the first TPC command and the first power offset is predefined.

[0346] As an example, the mapping between the first TPC command and the first power offset is determined according to Table 7.1.1-1 in 3GPP TS38.213.

[0347] As an example, the first TPC command is a TPC command field, and the value of this TPC command field is 3 out of 0, 1, 2, and 3.

[0348] As an example, the first TPC command is a TPC command field; when the codepoint of this TPC command field is "00", the value of this TPC command field is 0; when the codepoint of this TPC command field is "01", the value of this TPC command field is 1; when the codepoint of this TPC command field is "10", the value of this TPC command field is 2; when the codepoint of this TPC command field is "11", the value of this TPC command field is 3.

[0356] As an example, the first power offset is a power offset determined according to the first TPC command.

[0357] Example 10

[0358] Example 10 illustrates a schematic diagram showing the application of a first TPC command according to an embodiment of this application being delayed and not delayed, as shown in the attached diagram. Figure 10 As shown.

[0359] In Embodiment 10, the application of the first TPC command is postponed, including: the first TPC command is not used for the PUSCH power control adjustment corresponding to the first signal; the application of the first TPC command is not postponed, including: the first TPC command is used for the PUSCH power control adjustment corresponding to the first signal.

[0360] As an example, the PUSCH power control adjustment corresponding to the first signal is achieved by the following formula:

[0361]

[0362] Wherein, b represents the uplink BWP to which the first signal frequency domain belongs, f represents the carrier to which the first signal frequency domain belongs, c represents the serving cell to which the first signal belongs, i represents the index or number of the PUSCH transmission opportunity, l represents the index of the PUSCH power control adjustment state, and f represents the index of the PUSCH power control adjustment state. b,f,c (i, l) represents the PUSCH power control adjustment state corresponding to the first signal in PUSCH transmission opportunity i, and the f b,f,c (i-i0, l) represents the PUSCH power control adjustment state corresponding to the first signal in the PUSCH transmission opportunity i-i0, where D i Represents the first power offset set, the The δ represents the number of power offsets included in the first power offset set. PUSCH (m, l) represents a power offset in the first power offset set, where i0 is greater than 0.

[0363] As an example, PUSCH transmission opportunity i belongs to the first PUSCH resource pool.

[0364] As an example, PUSCH transmission opportunity i-i0 precedes PUSCH transmission opportunity i.

[0365] As an example, any power offset included in the first offset value set is an accumulated value.

[0366] As an example, the first power offset set is a set of TPC command values.

[0367] As an example, any power offset included in the first offset value set is a TPC command value, and the value of a TPC command field indicates a TPC command value.

[0368] As an example, any power offset in the first offset value set is a TPC command value received within a first time window, where the first time window is K before PUSCH transmission opportunity i-i0. PUSCH (i-i0)-1 symbols and PUSCH transmission opportunity i before K PUSCH (i) time windows between symbols, where i0 is the time window before K satisfying the PUSCH transmission opportunity i-i0. PUSCH (i-i0) symbols predate PUSCH transmission opportunity i by K. PUSCH The smallest positive integer of (i) symbols, wherein K PUSCH (i) is K PUSCH,min The number of symbols, the K PUSCH,min It equals the product of the number of symbols in each time slot and the minimum value provided by k2 in PUSCH-ConfigCommon.

[0369] As an example, the f b,f,c (i, l), the f b,f,c (i-i0, l), the δ PUSCH,b,f,c (m, l) are all relative to the uplink BWP to which the first signal frequency domain belongs.

[0370] As an example, the uplink BWP to which the first signal frequency domain belongs is defined in a carrier on a serving cell.

[0371] As an example, the f b,f,c (i, l), the f b,f,c (i-i0, l), the δ PUSCH,b,f,c (m, l) are indices for the same PUSCH power control adjustment state.

[0372] As an example, the f b,f,c (i, l), the f b,f,c (i-i0, l), the δ PUSCH,b,f,c (m, l) are both indices l that refer to the PUSCH power control adjustment state.

[0373] As an example, the index of a PUSCH power control adjustment state is the index of the closed power control loop to which the first signal belongs.

[0374] As an example, when the first power offset indicated by the first TPC command is not included in the first power offset set, the first TPC command is not used for PUSCH power control adjustment corresponding to the first signal.

[0375] As an example, when the first power offset indicated by the first TPC command is not taken into account... At that time, the first TPC command is not used for PUSCH power control adjustment corresponding to the first signal.

[0376] As an example, when the first power offset indicated by the first TPC command is included in the first power offset set, the first TPC command is used for PUSCH power control adjustment corresponding to the first signal.

[0377] As an example, when the first power offset indicated by the first TPC command is taken into account... At that time, the first TPC command is used for PUSCH power control adjustment corresponding to the first signal.

[0378] As an example, the terminal does not expect the PUSCH power control adjustment state corresponding to the first signal to change in different PUSCH transmission opportunities.

[0379] As an example, the change in PUSCH power control adjustment state corresponding to the first signal in different PUSCH transmission opportunities is not expected.

[0380] As an example, the terminal should expect that the PUSCH power control adjustment state corresponding to the first signal is the same in different PUSCH transmission opportunities.

[0381] Example 11

[0382] Example 11 illustrates a schematic diagram showing the transmission power of a first signal depending on a first power offset according to an embodiment of this application, as shown in the attached diagram. Figure 11 As shown.

[0383] In embodiment 11, the transmission power of the first signal is equal to the minimum of the first power threshold and the first power value; when the application of the first TPC command is not delayed, the first power value depends on the first power offset.

[0384] As an example, the transmission power of the first signal is equal to the smaller value (min) between the first power threshold and the first power value.

[0385] As an example, the transmission power of the first signal is the transmission power used by the terminal when transmitting the first signal.

[0386] As an example, the unit of the transmission power of the first signal is dBm (millidecibels).

[0387] As an example, when the first power threshold is greater than the first power value, the transmission power of the first signal is equal to the first power value; when the first power threshold is less than the first power value, the transmission power of the first signal is equal to the first power threshold; when the first power threshold is equal to the first power value, the transmission power of the first signal is equal to the first power threshold or the first power value.

[0388] As an example, the first power threshold is the configured maximum output power of the terminal.

[0389] As an example, the unit of the first power threshold is dBm (millidecibels).

[0390] As an example, the first power threshold is relative to a carrier occupied by a serving cell to which the first signal belongs.

[0391] As an example, the first power threshold is relative to a PUSCH transmission opportunity to which the first signal belongs.

[0392] As an example, the first power threshold is the P corresponding to the first signal. CMAX,f,c The value of (i).

[0393] As an example, the first power threshold is the P corresponding to the first signal. CMAX,f,c The value of PCMAX_L,f,c ≤P CMAX,f,c ≤P CMAX_H,f,c ;

[0394] Among them, P CMAX_L,f,c =MIN{P EMAX,c -ΔT C,c , (P PowerClass -ΔP PowerClass )-MAX(MAX(MPR c +ΔMPR c A-MPR c )+ΔT IB,c +ΔT C,c P-MPR c )},

[0395]

[0396] The P EMAX,c It is a value configured by a higher-level parameter, namely P. PowerClass The ΔP represents the power level of the terminal. PowerClass The offset of the power level of the terminal, ΔT IB,c This represents an additional tolerance value, ΔT. C,c The offset representing the lower tolerance limit, the MPR c The ΔMPR represents maximum power reduction. c The A-MPR represents an offset related to the relative channel bandwidth. c The P-MPR represents additional maximum power reduction. c This indicates the maximum power reduction in power management.

[0397] As an example, the unit of the first power value is dBm (millidecibels).

[0398] As an example, the first power value is equal to

[0399]

[0400] Wherein, b represents the uplink BWP to which the first signal frequency domain belongs, f represents the carrier to which the first signal frequency domain belongs, c represents the serving cell to which the first signal belongs, i represents the index or number of the PUSCH transmission opportunity, j represents the parameter set configuration with index, l represents the PUSCH power control adjustment state with index; μ represents the SCS (Subcarrier Spacing) configuration, which is determined by; P O_PUSCH,b,f,c (j) indicates that the component P O_NOMINAL,PUSCH,f,c (j) and component P O_UE_PUSCH,b,f,c A parameter consisting of the sum of (j); the The bandwidth representing PUSCH resource assignment is expressed in terms of the number of resource blocks; the α b,f,c (j) represents the path loss compensation factor; the PL b,f,c (q d ) represents the downlink path loss estimate calculated from the reference signal in the downlink BWP, where q d Indicates the reference signal index; the f b,f,c (i, l) represents the PUSCH power control adjustment state corresponding to the first signal in PUSCH transmission opportunity i; the Δ TF,b,f,c (i) is calculated.

[0401] As an example, the Δ TF,b,f,c (i) It is obtained by calculation using the following formula:

[0402]

[0403] Wherein, BPRE represents the bit per resource element value corresponding to the first signal, and K s Indicated by the higher-level parameter deltaMCS, the K s It equals 1.25 or 0, the stated It is equal to a predefined β offset value or a configured β offset value.

[0404] As an example, the first power value is equal to the sum of multiple components, including a first component, which is the PUSCH power control adjustment state corresponding to the first signal.

[0405] As an example, the first component is the f b,f,c (i, l).

[0406] As an example, when the application of the first TPC command is not delayed: the first component depends on the first power offset.

[0407] As an example, when the application of the first TPC command is not delayed: the first component and the first power offset are positively linearly correlated.

[0408] As an example, when the application of the first TPC command is not delayed: the coefficient of linear correlation between the first component and the first power offset is 1.

[0409] As an example, when the application of the first TPC command is postponed, the first power offset is not used in the calculation of the first power value during the PUSCH transmission opportunity i.

[0410] As an example, when the application of the first TPC command is delayed, the first power offset is not used in the calculation of the transmission power of the first signal during the PUSCH transmission opportunity i.

[0411] As an example, when the application of the first TPC command is delayed, the first power offset is used to calculate the first power value in a PUSCH transmission opportunity that is later than PUSCH transmission opportunity i.

[0412] As an example, when the application of the first TPC command is delayed, the first power offset is used to calculate the transmission power of the first signal in a PUSCH transmission opportunity later than PUSCH transmission opportunity i.

[0413] Example 12

[0414] Example 12 illustrates a schematic diagram showing that, according to an embodiment of this application, a symbol appears within a first duration after the last symbol of the PDCCH receiving the first signaling, as shown in the attached diagram. Figure 12 As shown. In the appendix Figure 12In the diagram, the bolded box represents the PDCCH that receives the first signaling, the diamond-filled portion within the bolded box represents the last symbol of the PDCCH that receives the first signaling, and the large grid-filled rectangle represents a symbol that appears within a first time period after the last symbol of the PDCCH that receives the first signaling.

[0415] As an example, the last symbol of a PDCCH is the latest symbol used for the transmission of this PDCCH in the time domain.

[0416] As an example, the last symbol of a PDCCH is the latest symbol occupied in the time domain of that PDCCH.

[0417] As an example, the first duration is T proc,2 ;

[0418] Among them, T proc,2 =max((N2+d 2,1 +d2)(2048+144)·κ·2 -μ ·T c +T ext +T switch d 2,2 The N2 depends on the SCS configuration μ; the μ corresponds to the smallest SCS configuration between the SCS configuration of the PDCCH receiving the first signaling and the SCS configuration of the first PUSCH; the d 2,1 The value is equal to 0; d2 is a predefined value or a value reported by the terminal; the d 2,2 Related to BWP (Bandwidth Part) switching; the T ext It relates to whether or not shared spectrum channel access operations are used in FR1; the T switch Related to the uplink switching gap; T c =1 / (Δf) max ·N f ), Δf max =480·10 3 Hz and N f =4096; κ=T s / T c =64,T s =1 / (Δf) ref ·N f,ref ), Δf ref =15·10 3 Hz and Nf,ref =2048.

[0419] As an example, if the terminal uses shared spectrum channel access operation in FR1, the T ext Calculated according to Clause 5.3.1 of 3GPP TS 38.211; otherwise, the T ext It equals 0.

[0420] As an example, the T switch It is configurable.

[0421] As an example, if the uplink handover interval is triggered, then the T switch The duration is equal to the corresponding switching gap duration; otherwise, the T... switch It equals 0.

[0422] As an example, if the scheduling DCI triggers a BWP switch, then the d 2,2 Equal to the corresponding switching time; otherwise, the d 2,2 It equals 0.

[0423] As an example, the SCS configuration μ corresponds one-to-one with the N2.

[0424] As an example, the correspondence between the SCS configuration μ and the N2 is predefined.

[0425] As an example, N2 is a function of the SCS configuration μ, which is predefined.

[0426] As an example, N2 = 5 is used for μ = 0, N2 = 5.5 is used for μ = 1, and N2 = 11 is used for μ = 2.

[0427] As an example, N2=10 is used for μ=0, N2=12 is used for μ=1, N2=23 is used for μ=2, N2=36 is used for μ=3, N2=144 is used for μ=5, and N2=288 is used for μ=6.

[0428] As an example, the T proc,2 The T c The T ext The T switch The d 2,2 Both are used to indicate a period of time.

[0429] As an example, the T proc,2 The T c The T extThe T switch The d 2,2 All units are time units.

[0430] As an example, if the first symbol of the first PUSCH resource pool appears within the first duration after the last symbol of the PDCCH that received the first signaling, the application of the first TPC command is postponed; otherwise, the application of the first TPC command is not postponed.

[0431] As an example, if the first symbol of the first PUSCH resource pool appears within the first duration after the last symbol of the PDCCH that received the first signaling, the application of the first TPC command is postponed; if the first symbol of the first PUSCH resource pool appears outside the first duration after the last symbol of the PDCCH that received the first signaling, the application of the first TPC command is not postponed.

[0432] As an example, if the first symbol of the first PUSCH resource pool precedes the last symbol of the PDCCH that receives the first signaling, the application of the first TPC command is postponed.

[0433] As an example, the application of the first TPC command is postponed, including: the terminal may postpone the application of the first TPC command.

[0434] Example 13

[0435] Example 13 illustrates a schematic diagram according to an embodiment of this application, where the first symbol of the first PUSCH resource pool follows the last symbol of the PDCCH receiving the first signaling, and the interval between the two is less than T symbols, as shown in the attached diagram. Figure 13 As shown. In the appendix Figure 13 In the diagram, the bolded box represents the PDCCH that receives the first signaling, the diamond-filled portion within the bolded box represents the last symbol of the PDCCH that receives the first signaling, each solid box represents a PUSCH transmission opportunity in the first PUSCH resource pool, and the large grid-filled portion within the solid box represents the first symbol of the first PUSCH resource pool.

[0436] As an example, the last symbol of a PDCCH is the latest symbol used for the transmission of this PDCCH in the time domain.

[0437] As an example, the last symbol of a PDCCH is the latest symbol occupied in the time domain of that PDCCH.

[0438] As an example, T is a positive integer greater than 1.

[0439] As an example, T is positively linearly correlated with the length of the orthogonal sequence of PUSCH determined according to the first configuration.

[0440] As an example, the coefficient of linear correlation between the length of T and the orthogonal sequence of PUSCH determined according to the first configuration is 1.

[0441] As an example, the advantages of the above method include: improved adaptability between the timeline conditions of the TPC command and the configuration of the orthogonal sequence of PUSCH.

[0442] As an example, T is not less than N2.

[0443] As an example, T is equal to the sum of the lengths of N2 and the orthogonal sequence of PUSCH determined according to the first configuration.

[0444] As an example, if the first symbol of the first PUSCH resource pool follows the last symbol of the PDCCH that received the first signaling and the interval between them is less than T symbols, then the application of the first TPC command is postponed; otherwise, the application of the first TPC command is not postponed.

[0445] As an example, if the first symbol of the first PUSCH resource pool follows the last symbol of the PDCCH that received the first signaling and the interval between them is less than T symbols, then the application of the first TPC command is postponed; if the first symbol of the first PUSCH resource pool follows the last symbol of the PDCCH that received the first signaling and the interval between them is not less than T symbols, then the application of the first TPC command is not postponed.

[0446] As an example, if the first symbol of the first PUSCH resource pool precedes the last symbol of the PDCCH that receives the first signaling, the application of the first TPC command is postponed.

[0447] As an example, the application of the first TPC command is postponed, including: the terminal may postpone the application of the first TPC command.
