[0133] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0134] In 5G networks, when terminals transmit uplink channels or signals, there may be temporal overlap between uplink signals. However, to ensure single-carrier characteristics and a low peak-to-average power ratio (PAPR), 5G New Radio (NR) stipulates that only one type of uplink channel or signal can be transmitted at any given time. That is, when there is temporal overlap between the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Share Channel (PUSCH), multiplexing rules are specified between PUCCH and PUSCH. This allows different types of uplink control information (UCI) to be multiplexed and transmitted on a single PUCCH, while still meeting the multiplexing processing time requirements. Furthermore, PUCCH can be multiplexed and transmitted on a PUSCH.

[0135] In NR networks, when the Sounding Reference Signal (SRS) used as an uplink signal overlaps with PUCCH / PUSCH, some drop rules are often specified to ensure that only one of the SRS and PUCCH / PUSCH is sent in order to avoid collisions.

[0136] In 6G networks, if multiple uplink channels or signals can be transmitted simultaneously on a single uplink carrier, the efficiency of uplink transmission can be greatly improved. Moreover, because 6G requires lower latency, if multiple uplink channels or signals are allowed to be transmitted simultaneously on a single uplink carrier, there is no need to always drop the transmission of some low-priority signals when the time domain resources of multiple uplink channels or signals overlap. This can effectively reduce the latency of low-priority signal transmission.

[0137] Meanwhile, 6G networks use Orthogonal Time Frequency Space (OTFS) waveforms as potential waveforms. The data modulation symbols of OTFS waveforms are generated in the delayed Doppler domain, and all modulation symbols are uniformly spread in the time and frequency domains. This allows for energy balance among the symbols through two-dimensional modulation, effectively reducing peak values ​​and resulting in a lower PAPR (PAR) for OTFS signals compared to Orthogonal Frequency-Division Multiplexing (OFDM) symbols. In contrast, OFDM waveforms transmit data in the time and frequency domains, with each data symbol having its own orthogonal frequency subcarrier. This structure can lead to an increase in PAPR to some extent.

[0138] Therefore, if the OTFS waveform is used in the 6G network, the low PAPR characteristic of the OTFS waveform can ensure that, unlike the 5G network, the OFDM waveform has a higher PAPR, so only one signal or channel can be transmitted on the uplink carrier at the same time in order to maintain a low PAPR.

[0139] However, if we consider transmitting multiple uplink signals or channels simultaneously on a single carrier in 6G, each uplink carrier has a maximum transmit power requirement (i.e., Pcmax). Therefore, we need to consider a power control method for transmitting multiple uplink signals or channels simultaneously, that is, how to ensure that the total transmit power of multiple uplink signals or channels transmitted simultaneously does not exceed Pcmax.

[0140] In view of this, embodiments of the present disclosure aim to provide a communication method that, when multiple uplink channels or signals overlap in time domain resources on an uplink carrier, can simultaneously transmit multiple channels or signals on the overlapping time domain resources, and ensure that power control can be achieved in this situation.

[0141] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0142] In step S2101, the terminal determines the priority order of multiple uplink transmissions that occupy time-frequency resources overlapping on the first uplink carrier.

[0143] In some embodiments, the first uplink carrier may be allocated by the network device to the terminal. For example, the first uplink carrier may be any one of a plurality of uplink carriers allocated by the network device to the terminal, but is not limited thereto.

[0144] In some embodiments, the time-domain resources occupied by multiple uplink transmissions on a first uplink carrier overlap.

[0151] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0153] In some embodiments, priority rules can be used to indicate the priority order between different types of uplink transmissions.

[0154] In some embodiments, the priority rules may be predefined, or they may be agreed upon by a protocol, but are not limited thereto.

[0155] For example, priority rules can be defined so that the priority order of different types of uplink transmissions can be determined according to the defined priority rules.

[0156] Taking uplink transmission, which includes five uplink channels or signals such as PUCCH, PUSCH, SRS, PRACH, and sensing RS, as an example, the priority rules can be as follows:

[0157] Sensing RS > PUCCH / PUSCH carrying at least one of Acknowledgement (ACK), Negative Acknowledgement (NACK), and Scheduling Request (SR) > PUCCH / PUSCH carrying other Uplink Control Information (UCI) > PUSCH without (without) UCI ​​> SRS / PRACH;

[0158] PUCCH / PUSCH carrying at least one of ACK, NACK, and SR signals > Sensing RS > PUCCH / PUSCH carrying other UCI signals > PUSCH without UCI signals > SRS / PRACH;

[0159] PUCCH / PUSCH carrying at least one of ACK, NACK, and SR signals > PUCCH / PUSCH carrying other UCI signals > Sensing RS > PUSCH without UCI signals > SRS / PRACH.

[0160] PUCCH / PUSCH carrying at least one of ACK, NACK, and SR signals > PUCCH / PUSCH carrying other UCI signals > PUSCH without UCI signals > Sensing RS > SRS / PRACH.

[0161] PUCCH / PUSCH carrying at least one of ACK, NACK, or SR signals > PUCCH / PUSCH carrying other UCI signals > PUSCH without UCI signals > SRS / PRACH > Sensing RS.

[0162] It should be noted that the above are only a few exemplary priority rules and do not constitute a limitation on specific priority rules. The specific content of the priority rules is not limited in the embodiments disclosed herein.

[0163] In some embodiments, the terminal may determine the priority order of multiple uplink transmissions based on multiple uplink transmission priority values.

[0164] In some embodiments, the uplink transmission priority value is predefined, or the uplink transmission priority value is preconfigured, or the uplink transmission priority value is indicated by the network device.

[0165] In some embodiments, the uplink transmission priority value is indicated by the network device. The network device can send first indication information to the terminal, which is used to indicate the uplink transmission priority value. The terminal can receive the first indication information sent by the network device to obtain the uplink transmission priority value indicated by the network device.

[0166] The following section uses several possible uplink signals or channels as examples to introduce the priority value configuration methods for uplink signals or channels.

[0167] Optionally, for the SR carried in the PUCCH, the network device can indicate the priority value of the SR carried in the PUCCH. Optionally, the priority value of the SR carried by the PUCCH resource can be indicated by the phy-PriorityIndex parameter in the PUCCH resource configuration of the SR.

[0168] Optionally, the priority value of Channel State Information (CSI) transmitted in the uplink channel can be predefined. Optionally, if CSI is transmitted in PUCCH, the priority of CSI can be fixed as low priority; if CSI is transmitted in PUSCH, the priority value of PUSCH can be used as the priority value of CSI.

[0169] Optionally, for Hybrid Automatic Repeat Requests (HARQs) carried in the PUCCH, the network device can indicate the priority value of the HARQ carried in the PUCCH. Optionally, for HARQs corresponding to Physical Downlink Shared Channels (PDSCHs) dynamically scheduled by Downlink Control Information (DCI), the priority value of the HARQ-ACK corresponding to the PDSCH can be indicated by the priority field of the DCI. Optionally, for HARQ information corresponding to PDSCHs in Semi-Persistent Scheduling (SPS), the priority value of the HARQ-ACK corresponding to the PDSCH of the SPS can be indicated by higher-layer parameters in the SPS configuration information.

[0170] In some embodiments, terms such as "physical downlink shared channel (PDSCH)" and "DL data" can be used interchangeably.

[0171] Optionally, the priority value of a PUSCH can be indicated by the network device. Optionally, if the PUSCH is scheduled via DCI, the priority value of the PUSCH can be indicated by the priority field of the DCI; if the PUSCH is allocated according to the resource configuration of Code Group 1 (CG1) or Code Group 2 (CG2), the priority value of the PUSCH can be indicated or configured by higher-layer signaling.

[0172] Optionally, for SRS, it can be set to low priority by default without defining a specific priority value. Alternatively, if the non-periodic SRS is sent by the DCI of the scheduling data (including but not limited to DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 1_0, DCI format 1_1, DCI format 1_2), the priority value of the triggered non-periodic SRS can be indicated by the priority field in the DCI.

[0173] Optionally, for PRACH, it can default to low priority without needing to define a specific priority value.

[0174] Optionally, the priority value of the sensing RS can be predefined or preconfigured, or its priority value can be indicated by the network device through the DCI of the sensing RS sent by the triggering terminal. That is, the network device can send the DCI of the triggering terminal to the terminal to send the sensing RS, and the DCI of the triggering terminal to send the sensing RS can include the first indication information.

[0175] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0176] It should be noted that the above is only an exemplary description of several possible methods for configuring the priority values ​​of uplink signals or channels, and does not constitute a limitation on the embodiments of this disclosure. In more possible implementations, other methods can be used to implement the configuration of priority values ​​for various uplink signals or channels, and the embodiments of this disclosure do not limit this.

[0177] In some embodiments, a smaller priority value corresponds to a higher priority, and vice versa.

[0178] For example, for a sensing RS, two priority values ​​can be defined, such as priority value 0 and priority value 1, where the priority of value 0 is higher than the priority of value 1; or, multiple priority values ​​can be defined for a sensing RS, such as priority values ​​{0,1,2,3,…,7}, where priority value 0 represents the highest priority and priority value 7 represents the lowest priority.

[0179] In some embodiments, for uplink transmissions with the same priority value, the priority order among uplink transmissions with the same priority value can be determined based on priority rules. For an introduction to priority rules, please refer to the previous text, which will not be repeated here.

[0180] In step S2102, the terminal sends at least one uplink transmission among the multiple uplink transmissions to the network device on the first uplink carrier based on the priority order of the multiple uplink transmissions.

[0181] In some embodiments, the priority order of multiple uplink transmissions can be determined based on priority rules. Then, the terminal can determine at least one uplink transmission transmitted on the first uplink carrier from the multiple uplink transmissions in descending order of priority.

[0182] In some embodiments, the priority order of multiple uplink transmissions can be determined based on priority values. In this case, the terminal can determine at least one uplink transmission to be transmitted on the first uplink carrier from the multiple uplink transmissions in ascending order of priority values.

[0183] In some embodiments, the terminal may transmit at least one of a plurality of uplink transmissions on the first uplink carrier in descending order of priority, until the total transmit power of the uplink transmissions transmitted on the first uplink carrier is less than or equal to the maximum transmit power of the first uplink carrier.

[0184] In some embodiments, the maximum transmit power of the first uplink carrier may be pre-configured, but is not limited thereto.

[0185] It should be noted that the total power of all uplink channels or signals that the terminal can transmit on the first uplink carrier is not infinite. The maximum transmission power of the first uplink carrier defines the maximum value of the total power of all uplink channels or signals that the terminal can transmit on the first uplink carrier. The terminal needs to transmit multiple uplink channels or signals simultaneously on the first uplink carrier without exceeding this maximum transmission power.

[0186] In some embodiments, for any one of the at least one uplink transmissions transmitted on a first uplink carrier, the transmission power of the uplink transmission can be a first transmission power or a second transmission power.

[0187] In some embodiments, the first transmission power can be determined based on a method agreed upon in the protocol. Optionally, the first transmission power can be determined based on a power formula defined in the protocol. For example, the first transmission power can be determined based on a power formula defined in the Release 15 (R15) protocol.

[0188] The following section uses several possible uplink signals or channels as examples to introduce the process of determining the first transmit power using the power formula defined in the R15 protocol.

[0189] Alternatively, for the PUCCH, its first transmit power can be determined by the following formula:

PL represents the normalized power value on the resources occupied by the PUCCH. b,f,c (q d ) represents the path loss value between the terminal and the network device, PL b,f,c (q d Δ can be obtained by the terminal based on the reference signal. F_PUCCH (F) represents the power offset value determined according to the different formats of PUCCH, Δ TF,b,f,c (i) represents the receive power required by the network device, Δ TF,b,f,c (i) can be determined based on the modulation scheme, channel coding rate, and the number of bits of information per resource unit, g b,f,c (i,l) represents the closed-loop power value, g b,f,c (i,l) can be the power adjustment value determined by the network device based on measurements.

[0191] Alternatively, for PUSCH, its first transmit power can be determined by the following formula:

[0193] Alternatively, for SRS, its first transmit power can be determined by the following formula:

[0194] Among them, P SRS,b,f,c (i,q s ,l) represents the first transmit power of the SRS, P CMAX,f,c (i) represents the maximum power limit, P O_SRS,b,f,c (q s ) represents the initial power offset of the SRS, 10log 10 (2 μ ·M SRS,b,f,c (i) represents the normalized power value on the resources occupied by the SRS, PL b,f,c (q s ) represents the path loss value between the terminal and the network device, PL b,f,c (q s α can be obtained by the terminal based on the reference signal. SRS,b,f,c (q s ) represents the road loss compensation coefficient, h b,f,c (i,l) represents the closed-loop power value, h b,f,c (i,l) can be the power adjustment value determined by the network device based on measurements.

[0195] Alternatively, for a sensing RS, its first transmit power can be determined by the following formula:

[0196] Among them, P sensing RS,b,f,c (i,q s ,l) represents the first transmit power of the sensing RS, P CMAX,f,c (i) represents the maximum power limit, P O_sensing RS,b,f,c (q s ) represents the initial power offset of the sensing RS, 10log 10 (2 μ ·M sensing RS,b,f,c (i) represents the normalized power value on the resources occupied by the sensing RS, PL b,f,c (q s ) represents the path loss value between the terminal and the network device, PL b,f,c (q s ) can be obtained by the terminal based on the reference signal, αsensing RS,b,f,c(q s ) represents the road loss compensation coefficient, h b,f,c (i,l) represents the closed-loop power value, h b,f,c (i,l) can be the power adjustment value determined by the network device based on measurements.

[0197] It should be noted that the formula for determining the first transmission power of the sensing RS described above can be applied to situations where the sensing transmitter is a terminal and the sensing receiver is a network device (such as a base station), but is not limited to this.

[0198] Alternatively, for a sensing RS, its first transmit power can also be determined by the following formula:

[0199] Among them, P sensing RS,b,f,c (i,q s ,l) represents the first transmit power of the sensing RS, P CMAX,f,c (i) represents the maximum power limit, P O_sensing RS,b,f,c (q s ) represents the initial power offset of the sensing RS, 10log 10 (2 μ ·M sensing RS,b,f,c (i) represents the normalized power value on the resources occupied by the sensing RS, PL b,f,c (q s ) represents the path loss value between the terminal and the network device, PL b,f,c (q s) can be obtained by the terminal based on the reference signal, αsensing RS,b,f,c(q s ) represents the road loss compensation coefficient.

[0200] It should be noted that the formula for determining the first transmission power of the sensing RS described above can be applied to the case where the sensing transmitter is a terminal and the sensing receiver is another terminal, but it is not limited to this.

[0201] It should be noted that the above is only an exemplary description of several possible methods for configuring the priority values ​​of uplink signals or channels, and does not constitute a limitation on the embodiments of this disclosure. In more possible implementations, other methods can be used to implement the configuration of priority values ​​for various uplink signals or channels, and the embodiments of this disclosure do not limit this.

[0202] In some embodiments, the first transmit power may be determined not only based on a protocol-agreed method, but also predefined, preconfigured, or indicated by the network device.

[0203] For example, in the case of uplink transmission being Sensing RS, the first transmit power can also be predefined, or it can also be preconfigured, or it can also be indicated by the network device.

[0204] In some embodiments, when the uplink transmission is a sensing RS, the network device may send a second indication information to the terminal. The second indication information is used to indicate the first transmission power of the sensing RS. The terminal may receive the second indication information sent by the network device to obtain the first transmission power of the sensing RS.

[0205] In some embodiments, the network device can dynamically indicate the second indication information through physical layer signaling; that is, the network device can dynamically indicate the first transmit power of the sensing RS through physical layer signaling.

[0206] In some embodiments, the name of the first transmission power is not limited, and it may be, for example, "first power", "first power value", etc.

[0207] In some embodiments, the second transmission power can be obtained by reducing the power based on the first transmission power.

[0208] It should be noted that, in order to ensure that the uplink transmission effect can still be guaranteed to a certain extent when the uplink transmission power is reduced, the first transmission power needs to be reduced within a certain range to obtain the second transmission power.

[0209] In some embodiments, the second transmission power can be a power value that is greater than or equal to the product of the first transmission power and the first proportional parameter, but less than the first transmission power. That is, if the second transmission power is greater than or equal to the product of the first transmission power and the first proportional parameter, but less than the first transmission power (i.e., first transmission power × X% ≤ second transmission power < first transmission power, where X% is the first proportional parameter), then uplink transmission can be achieved by reducing power; otherwise, the uplink transmission will not be transmitted on the first uplink carrier.

[0210] In some embodiments, the first proportional parameter may be predefined, preconfigured, or indicated by the network device.

[0211] In some embodiments, a network device may send a third indication information to a terminal, the third indication information being used to indicate a first proportional parameter; the terminal may receive the third indication information sent by the network device to obtain the first proportional parameter.

[0212] In some embodiments, the network device can dynamically indicate the third indication information via physical layer signaling; that is, the network device can dynamically indicate the first proportional parameter via physical layer signaling. Optionally, the physical layer signaling can be DCI, but is not limited thereto.

[0213] In some embodiments, the second transmission power can be a power value that is greater than or equal to a power threshold and less than the first transmission power. That is, if the second transmission power is greater than or equal to the power threshold and less than the first transmission power (i.e., power threshold ≤ second transmission power < first transmission power), the uplink transmission can be achieved by reducing the power; otherwise, the uplink transmission is not transmitted on the first uplink carrier.

[0214] In some embodiments, the power threshold is predefined, or the power threshold is preconfigured, or the power threshold is indicated by the network device.

[0215] In some embodiments, the network device may send a fourth indication information to the terminal, the fourth indication information being used to indicate a power threshold; the terminal may receive the fourth indication information sent by the network device to obtain the power threshold.

[0216] In some embodiments, the network device can dynamically indicate the fourth indication information via physical layer signaling; that is, the network device can dynamically indicate the power threshold via physical layer signaling. Optionally, the physical layer signaling can be DCI, but is not limited thereto.

[0217] In some embodiments, the name of the second transmission power is not limited, and it may be, for example, "second power", "second power value", etc.

[0218] In some embodiments, the uplink transmissions can be prioritized and transmitted on the first uplink carrier at a first transmit power, in descending order of priority. That is, if the first transmit power of a high-priority uplink transmission is less than or equal to the maximum transmit power of the first uplink carrier, then the high-priority uplink transmission is transmitted on the first uplink carrier at the first transmit power. If the first transmit power of a high-priority uplink transmission is less than the maximum transmit power of the first uplink carrier, then the next highest priority uplink transmission is transmitted, which is transmitted at the first transmit power or at a reduced power to the second transmit power. This process is repeated until the total transmit power of the uplink transmissions transmitted by the terminal is less than or equal to the maximum transmit power of the first uplink carrier.

[0219] Optionally, the priority order of multiple uplink transmissions can be determined based on priority rules, and at least one uplink transmission can be transmitted on the first uplink carrier in the manner described above, according to the priority order determined based on the priority rules, in descending order of priority.

[0220] Optionally, if all uplink transmissions with overlapping time-domain resources on the first uplink carrier have corresponding priority values, the priority values ​​of multiple uplink transmissions can be compared together to achieve the transmission of at least one uplink transmission on the first uplink carrier in ascending order of priority value, using the method described above.

[0221] To facilitate understanding, the following two specific examples will be used to introduce the uplink transmission process based on priority rules and priority values, respectively.

[0222] Example 1: The following priority rule can be defined: Sensing RS > PUCCH / PUSCH carrying at least one of ACK, NACK, or SR > PUCCH / PUSCH carrying other UCIs > PUSCH without UCIs > SRS / PRACH. Where, if the first transmit power of the SRS signal transmitted on the first uplink carrier is P1, the first transmit power of the PUCCH carrying ACK or NACK is P2, and the first transmit power of the PUSCH carrying data is P3, and the three signals and channels overlap in time-domain resources, then the terminal prioritizes transmitting the PUCCH carrying ACK or NACK at the first transmit power P1. Furthermore, subsequent transmission behaviors can include the following cases:

[0223] Case 1: If the first transmit power P1 is equal to Pcmax, then after the terminal transmits PUCCH at the first transmit power, it will not transmit any other uplink channels or signals.

[0224] Case 2: If the first transmission power P1 is less than Pcmax, and the remaining transmission power of the terminal is Pcmax-P1, then the terminal determines the transmission power of the next priority signal (i.e., the PUSCH carrying data). Specifically, the following scenarios may apply:

[0225] Case 2-1: If Pcmax-P1≥P2, then the terminal transmits PUSCH at the first transmit power P2.

[0226] Case 2-2: When Pcmax-P1 < P2, if P2×X% ≤ Pcmax-P1 < P2, then the terminal uses power Pcmax-P1 as the second transmission power to transmit PUSCH.

[0227] Furthermore, based on case 2-1, if pcmax - P1 - P2 > 0, the terminal continues to determine whether to send SRS, and there may be several possible scenarios:

[0228] Case 2-1-1: If Pcmax-P1-P2≥P3, then the terminal continues to transmit SRS at the first transmission power P3.

[0229] Case 2-1-2: When Pcmax-P1-P2 < P3, determine whether P3×X% ≤ Pcmax-P1-P2 < P3. If it is satisfied, then transmit SRS with Pcmax-P1-P2 as the second transmission power; otherwise, do not transmit SRS.

[0230] Example 2: The uplink signals or channels that need to be transmitted on the first uplink carrier include a sensing RS, a PUCCH carrying HARQ, and a PUSCH carrying data. These three channels or signals overlap in the time domain. The sensing RS has a priority value of 3, the PUCCH carrying HARQ has a priority value of 0, and the PUSCH carrying data has a priority value of 1. The first transmit power of the sensing RS is P1, the first transmit power of the PUCCH carrying HARQ is P2, and the first transmit power of the PUSCH carrying data is P3. Comparing the priority values ​​of the three signals, the order is: PUCCH carrying HARQ < PUSCH carrying data < sensing RS. Therefore, the terminal prioritizes transmitting the PUCCH, then decides whether to transmit the next highest priority PUSCH, and finally decides whether to transmit the lowest priority sensing RS. Several possible scenarios exist:

[0231] Case 1: If the first transmit power P2 of PUCCH is equal to Pcmax, then the terminal transmits PUCCH at the first transmit power P2 and does not transmit other channels or signals.

[0232] Scenario 2: If the initial transmission power P2 of PUCCH is less than Pcmax, and the remaining power of the terminal is Pcmax-P2, then the terminal determines whether to transmit the secondary priority signal PUSCH, and the transmission power of PUSCH. Specifically, the following scenarios may occur:

[0233] Case 2-1: If Pcmax-P2≥P3, then the terminal transmits PUSCH at the first transmit power P3.

[0234] Case 2-2: When Pcmax-P2 < P3, if P3×X% ≤ Pcmax-P2 < P3, the terminal transmits PUSCH with power Pcmax-P2 as the second transmission power.

[0235] Furthermore, based on case 2-1, if Pmax - P2 - P3 > 0, the terminal continues to determine whether to send SRS, and there may be several possible scenarios:

[0236] Case 2-1-1: If Pcmax-P2-P3≥P1, the terminal continues to send SRS and sends SRS at the first transmission power P1.

[0237] Case 2-1-2: When Pcmax-P2-P3 < P1, determine whether P1×X% ≤ Pcmax-P2-P3 < P1. If it is satisfied, then transmit SRS with pcmax-P2-P3 as the second transmission power; otherwise, do not transmit SRS.

[0238] In some embodiments, the network device may receive at least one uplink transmission sent by the terminal on a first uplink carrier.

[0239] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0240] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0241] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0242] In some embodiments, the determination or judgment can be made by a value represented by 1 bit (0 or 1), or by a true or false value (boolean), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value), but is not limited thereto.

[0243] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the receiver to respond to the sent content.

[0244] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2102. For example, step S2102 may be implemented as a standalone embodiment, and steps S2101+S2102 may be implemented as standalone embodiments, but are not limited thereto.

[0245] In some embodiments, step S2101 is optional and may be omitted or replaced in different embodiments.

[0246] In some embodiments, other optional implementations described before or after the specification corresponding to FIG2 may be referred to.

[0247] On a single uplink carrier, the maximum transmit power is Pcmax, which is pre-configured. Uplink signals or channels include at least one of: PUCCH, PUSCH, SRS, PRACH, and Sensing RS. In other words, the maximum transmit power defines the maximum sum of power of all channels / signals that the terminal can transmit on a single uplink carrier. If multiple channels / signals can be transmitted simultaneously without exceeding this maximum value, then the terminal can achieve simultaneous uplink signal / channel transmission.

[0248] According to the scheme provided in the embodiments of this disclosure, when multiple uplink channels or signals overlap in time domain resources on a single uplink carrier, it is permissible to transmit multiple channels or signals simultaneously on the overlapping time domain resources. Power control can then be implemented using the following method:

[0249] Method 1: Define signal priority rules. According to these rules, prioritize high-priority channels or signals by sending them at the first transmission power determined by the formula defined in 38.213. If the terminal's transmission power is still less than Pcmax, continue sending the next highest priority signal or channel. This next highest priority signal or channel is then sent at the first transmission power determined by the formula in 38.213, or at a reduced power (the second highest priority). This process is repeated until the total transmission power of the uplink channels or signals sent by the terminal is less than or equal to Pcmax. The priority rules have the following possibilities:

[0250] sensing Rs>PUCCH / PUSCH with ACK / NACK and / or SR>PUCCH / PUSCH with other UCIs>PUSCH w / o UCI>SRS / PRACH;

[0251] PUCCH / PUSCH with ACK / NACK and / or SR>sensing Rs>PUCCH / PUSCH with other UCIs>PUSCH w / o UCI>SRS / PRACH;

[0252] PUCCH / PUSCH with ACK / NACK and / or SR>PUCCH / PUSCH with other UCIs>sensing Rs>PUSCH w / o UCI>SRS / PRACH;

[0253] PUCCH / PUSCH with ACK / NACK and / or SR>PUCCH / PUSCH with other UCIs>PUSCH w / o UCI>sensing Rs>SRS / PRACH

[0254] PUCCH / PUSCH with ACK / NACK and / or SR>PUCCH / PUSCH with other UCIs>PUSCH w / o UCI>SRS / PRACH>sensing Rs.

[0255] Method 2: When multiple uplink signals or channels overlapping on a carrier have corresponding priority values, the priority values ​​of the various signals transmitted on the uplink carrier are compared together. The channel or signal with the highest priority is given priority and transmitted at the first transmission power determined by the formula defined in the protocol. If the terminal's transmission power is still less than Pcmax, the signal or channel with the second highest priority is transmitted. The signal or channel with the second highest priority is transmitted at the first transmission power determined by the formula defined in the protocol, or the first transmission power is reduced to the second transmission power. This process is repeated until the total transmission power of the terminal transmitting uplink channels or signals is less than or equal to Pcmax.

[0256] Optionally, when a priority value is defined for the sensing RS, the sensing RS priority value is predefined, preconfigured, or determined by triggering the UE to send a DCI indication of the sensing RS.

[0257] For example, two priority values ​​can be defined for sensing RS: 0 and 1, with a value of 0 having a higher priority than a value of 1. Alternatively, multiple priority values ​​can be defined for sensing RS, such as the priority values ​​{0, 1, 2, 3, ..., 7}, where a priority value of 0 indicates a higher priority. The reverse is also true.

[0258] It should be noted that when multiple uplink signals or channels have the same priority value, the transmission of the uplink signal or channel shall be determined according to the rules defined above.

[0259] The first transmit power value is the transmit power of each signal or channel determined according to the power formula for that channel or signal as defined in 38.213.

[0260] As for the second transmission power, there are two ways to determine it:

[0261] Method 1: The uplink signal or channel is reduced in power based on the corresponding first power value to obtain the second power value. Furthermore, the following relationship must be satisfied: first transmit power × X% ≤ second transmit power < first transmit power. Otherwise, the uplink will not transmit that signal or channel, even if the terminal's total uplink transmit power is less than Pcmax (this is to ensure that the reduced power value cannot fall below a certain threshold when transmitting the channel or signal with reduced power). Here, X% is predefined, pre-configured, or dynamically indicated by physical layer signaling (such as DCI indication).

[0262] Method 2: The power value obtained by reducing the power of the uplink signal or channel based on the corresponding first power value is the second power value, and the following relationship must be satisfied: power threshold ≤ second transmission power < first transmission power, where the power threshold is predefined, preconfigured, or dynamically indicated by physical layer signaling (such as DCI indication).

[0263] Optionally, the first transmit power of the sensing RS can also be a predefined, preconfigured, or dynamically indicated value by physical layer signaling.
