In some scenarios, for example, scenarios such as drone, 4K high definition live, etc., there are requirements for uplink coverage and transmission rate. In uplink transmission, uplink power control is a technique that can achieve better coverage and transmission rate. For example, for terminal devices (or called edge users) farther from the base station, the path loss of the terminal devices is larger, and the edge users can use larger transmission power than the terminal devices (or called center users) closer to the base station, so as to compensate the path loss caused by long-distance transmission, and enable the edge users to obtain better uplink coverage and transmission rate performance.

In order to improve uplink coverage, a possible implementation manner is that a terminal device configured with a high-power amplifier (or called power amplifier) may support sending a signal with a maximum transmission power (for example, 23 dBm) higher than that specified by a standard within a certain time, so that through instantaneous high-power sending, when the terminal device is located at a cell edge or a large data packet exists for transmission, the transmission rate of the terminal device is increased, and further, the user experience is improved. However, long-term use of high-power transmission signals may cause the total power of the terminal equipment to not meet the requirements of regulations or cause radiation to human bodies. Therefore, the average transmit power of the terminal device or the total energy used by the terminal device for signal transmission over a period of time needs to satisfy a condition that does not exceed a certain threshold.
For example, as shown in fig. 4, during a time period with a length T (hereinafter referred to as time period T), the terminal device may transmit an uplink signal with a maximum transmission power higher than the maximum transmission power specified in the standard (hereinafter referred to as instantaneous high power); however, in a time period with a length L (hereinafter referred to as a time window), the average power of the terminal device does not exceed the maximum transmission power of the terminal device specified in the standard, wherein the time period T is within the time window, and the length of the time period T is smaller than or equal to the time window. In other words, in this scenario, the energy used by the terminal device for uplink transmission is constant within the time window, and the terminal device can transmit the uplink signal with instantaneous high power within a certain time period. When the terminal device transmits with the instantaneous high power for a period of time, it may cause that the energy available for uplink transmission by the terminal device is insufficient (or called energy overdraft), and even the energy available for uplink transmission is zero, at this time, if the network device still schedules the terminal device to transmit an uplink signal, it may cause that the transmission of the uplink signal by the terminal device fails due to the insufficient energy of uplink transmission, and affect the uplink coverage and the uplink transmission rate.
Based on this, embodiments of the present application provide a communication method and a communication apparatus, so as to improve uplink coverage and uplink transmission rate.
Referring to fig. 5, an embodiment of a communication method provided by the present application includes:
s501, the terminal device determines available uplink transmission energy in a first time period, wherein the first time period comprises a plurality of time units.
The available uplink transmission energy is used for transmitting an uplink signal, and may also be referred to as available uplink transmission energy, or referred to as energy available for uplink transmission, or referred to as Residual Transmit Energy (RTE), or other names. The available uplink transmission energy in the first time period refers to energy available for transmitting an uplink signal in the first time period.
The uplink signal may be at least one of the following: uplink data, uplink control signaling, or uplink reference signals. Specifically, the uplink data may be uplink service data; the uplink control signaling may be a Scheduling Request (SR), a Channel Quality Indicator (CQI), an Acknowledgement (ACK), or a negative acknowledgement (negative acknowledgement); the uplink reference signal may be an uplink demodulation reference signal (DMRS), a channel sounding signal (SRS), a preamble, or the like.
Optionally, the available uplink transmission energy is energy used for uplink signal transmission (or energy available for uplink transmission) in the first time period of the time window; the time window is a time period when the average transmitting power of the terminal equipment does not exceed a certain threshold; or, the time window is a time period during which the terminal device can transmit the uplink signal with a maximum transmission power (hereinafter referred to as instantaneous high power) higher than the maximum transmission power specified in the standard; or, the time window is a time period for the terminal device to evaluate available uplink transmission energy; or the energy used by the terminal device for uplink signal transmission in the time window does not exceed the second threshold.
It will be appreciated that the terminal device may transmit the uplink signal at an instantaneous high power during the time window, but that the average transmit power of the terminal device during the time window does not exceed the maximum transmit power of the terminal device as specified in the standard. Alternatively, it can be understood that the terminal device can transmit the uplink signal with an instantaneous high power within a time window, but the energy of the terminal device for uplink transmission does not exceed the second threshold value within the time window. Optionally, the second threshold may be a product of a maximum transmission power of the terminal device and a length of the time window.
Optionally, the position of the first time period may be represented in various ways, for example, it may be represented by a start time unit of the first time period and an end time unit of the first time period; alternatively, it may be represented by a start time unit of the first period and a time length of the first period. Correspondingly, the terminal device may determine the corresponding time domain resource of the first time period according to the start time unit of the first time period and the end time unit of the first time period; alternatively, the terminal device may determine the position of the first period of time from a start time unit of the first period of time and a time length of the first period of time.
Optionally, the starting time unit of the first time period is a time unit for sending first indication information by the terminal device; or the starting time unit of the first time period is the kth time unit after the time unit of the third indication information from the network equipment is received, the third indication information is used for indicating the terminal equipment to report the first indication information, and k is a natural number; alternatively, the starting time unit of the first time period is determined according to configuration information sent by the network device.
Optionally, the available uplink transmission energy is energy available for uplink transmission from the start time unit to the end of the end time unit; wherein, the termination time unit is a time unit corresponding to the end position of the time window; or, the termination time unit is determined according to configuration information sent by the network device. Optionally, the configuration information includes at least one of: a time length of the first period, information of a start time unit of the first period, or information of an end time of the first period.
Further, the information of the start time unit of the first time period is an index of the start time unit of the first time period.
Further, the information of the ending time unit of the first time period is an index of the ending time unit of the first time period.
Further, the index of the start time unit and the index of the end time unit of the first time period may be indexes corresponding to an offset (or referred to as offset position) with respect to the start position of the time window; alternatively, the two indexes may also be position indexes relative to a certain time reference point, where the position of the time reference point may be a boundary of a certain radio frame (e.g., an upper boundary or a lower boundary of the radio frame) and/or a boundary of a certain radio subframe (e.g., an upper boundary of the radio subframe and a lower boundary of the radio subframe), which is not limited in this application. Furthermore, the location of the time reference point may be protocol preset or network device indicated.
Alternatively, the offset may be in units of time units; the value of the offset may be a natural number, for example, the offset is 0, 1, or 2, and the application is not limited thereto.
Optionally, the configuration information may be carried in a radio resource control RRC message.
Alternatively, the time units may be subframes, slots, symbols, or time units of other granularity.
Optionally, the value of k may be preset by a protocol or an indication of a network device, which is not limited in this application.
Optionally, the method further comprises: the terminal equipment receives third indication information from the network equipment, wherein the third indication information is used for indicating the terminal equipment to report the first indication information; or the third indication information is used for indicating the terminal equipment to send the first indication information.
Optionally, the third indication information is carried in a radio resource control RRC message, or a PDCCH or a MAC CE.
Alternatively, the location of the time window may be a protocol preset; alternatively, the location of the time window is determined from location information of the time window from the network device.
Further, the time window may be a preset time unit, or a preset plurality of time units that are consecutive in the time domain. It can be understood that the uplink transmission energy of the terminal device does not exceed a certain threshold in a preset time unit or a preset plurality of time units that are consecutive in the time domain. Here, the time unit may be a radio frame, a subframe, a slot, a symbol, or a time unit of other granularity.
For example, the time window may be one radio frame, or the time window may be a plurality of preset radio frames that are consecutive in the time domain; it can be understood that the uplink transmission energy of the terminal device does not exceed a certain threshold in a predetermined radio frame or a predetermined plurality of radio frames consecutive in the time domain. In a possible implementation, the time window may be a radio frame M (or referred to as a radio frame with sequence number M), where M is a positive integer, and a value of M may range from 0 to 1023, for example, M is 10, 100, or 500. In another possible implementation, the time window may be N radio frames starting at radio frame M and consecutive in the time domain, where M and N are positive integers.
Further, there are various ways of representing the position information of the time window, for example, the position information of the time window may be represented by a parameter related to a period, or the position information of the time window may be represented by a parameter related to a timer, as described in the following ways a1 and a2:
mode a1: the position information of the time window is represented by the cycle-dependent parameter information.
In this manner, the time window occurs periodically, and the position information of the time window may include at least one of: a first period, a first starting location, a first offset, or a first duration.
For example, the time window includes a first period T, a first offset, and a first duration. Accordingly, the terminal device may determine the first starting position according to the System Frame Number (SFN) and the first period T, further determine the starting position of the time window according to the first starting position and the first offset, and determine the duration of the time window (or the length of the time window) according to the first duration.
The system frame number at which the first start position is located may satisfy one of the following equations: SFN mod T =0; SFN mod T = offset; (SFN + offset) mod T =0.
Optionally, the first offset takes a natural number.
Further, when the first offset value is 0, the first offset value with a value of 0 may be carried in the position information of the time window; alternatively, the first offset may not be carried in the position information of the time window, in other words, if the first offset is not included in the position information of the time window, the first offset may be set to 0 by default.
Mode a2: the position information of the time window is represented by a timer-related parameter.
In this manner, the position information of the time window includes: and a first timer, wherein the terminal device can determine the time window according to the first timer.
For example, the terminal device starts (restarts) a first timer, and before the first timer expires, the terminal device determines the corresponding time as the time of the time window; and restarting the first timer if the first timer is overtime.
Optionally, the time when the terminal device starts the first timer may be preset by a protocol or indicated by the network device.
Optionally, the position information of the time window may be carried in a radio resource control RRC message, or a PDCCH or a MAC CE.
Optionally, there are various ways for the terminal device to determine the available uplink transmission energy in the first time period, and the following description is made in a way b1:
mode b1: the terminal equipment determines the available uplink transmission energy in the first time period according to the first energy value of the terminal equipment in the time window and the uplink transmission energy which is used by the terminal equipment before the starting time corresponding to the first time period of the time window.
In this way, the terminal device determines the available uplink transmission energy in the first time period according to the first energy value of the terminal device in the time window and the uplink transmission energy already used by the terminal device.
Alternatively, the first energy value may be a maximum value of energy that the terminal device is configured to use for uplink signal transmission.
Alternatively, the first energy value may be preset or determined according to the maximum transmission power of the terminal device and the length of the time window specified in the standard.
Further, the first energy value is equal to a product between a maximum transmission power of the terminal device specified in the standard and a length of the time window.
Further, the maximum transmission power of the terminal device specified in the standard may be 23dBm, 26dBm, or 14dBm. It should be noted that, in this embodiment, if the terminal device determines that the value of the available uplink transmission energy in the first time period is not an integer, the value may be corrected by rounding up or rounding down, which is not limited in this application.
S502, the terminal equipment sends first indication information, and the first indication information is used for indicating the available uplink sending energy.
Accordingly, the network equipment receives the first indication information sent by the terminal equipment.
Optionally, the first indication information is at least one of: the uplink transmission power may be an available uplink transmission energy, an index of the available uplink transmission energy, an average transmission power of the uplink signal transmitted in the first time period, or an index of the average transmission power of the uplink signal transmitted in the first time period.
Optionally, the average transmission power for transmitting the uplink signal in the first time period is a ratio of the available uplink transmission energy to the number of all time units included in the first time period, or the average transmission power for transmitting the uplink signal in the first time period is an average value of the transmission powers for transmitting the uplink signal in all time units included in the first time period.
It should be noted that, the average value is obtained by assuming that the terminal device transmits signals in each time unit included in the first time period, so that the terminal device calculates the average transmission power for transmitting uplink signals in the first time period according to the transmission power used by each time unit for transmitting uplink signals in the first time period.
It should be noted that, the first time period is known by both the network device and the terminal device, and it can be understood that the network device and the terminal device have the same understanding of the first time period, so that both devices can determine the same available uplink transmission energy according to the first indication information based on the same understanding of the first time period. In one possible design, the first time period may be determined by the terminal device based on configuration information of the network device, or may be determined by the terminal device itself; optionally, the terminal device may send the first time period determined by itself to the network device through a high-level signaling; here, the higher layer signaling may be RRC message, or MAC CE, which is not limited in this application.
For example, if the average transmission power for transmitting the uplink signal in the first time period is the ratio of the available uplink transmission energy to the number of all time units included in the first time period, the terminal device determines, through S501, that the available uplink transmission energy value in the first time period is x, and the number of all time units included in the first time period is y, then the terminal device determines that the average transmission power for transmitting the uplink signal in the first time period is x/y.
For another example, if the average transmission power for transmitting the uplink signal in the first time period is the average value of the transmission powers for transmitting the uplink signals in all time units included in the first time period, and the terminal device determines that the transmission power used for transmitting the uplink signal in each time unit included in the first time period is z1, z2, z3, z4, and z5, respectively, then the terminal device determines that the average transmission power for transmitting the uplink signal in the first time period is (z 1+ z2+ z3+ z4+ z 5)/5.
Further, when the first indication information is an index of available uplink transmission energy, the method further includes:
determining an index of uplink transmission energy according to the available uplink transmission energy and a first corresponding relation, wherein the first corresponding relation is the corresponding relation between the available uplink transmission energy and the index of the uplink transmission energy; or,
further, when the first indication information is an index of the average transmission power of the uplink signal transmitted in the first time period, the method further includes:
and determining an index of the average transmitting power according to the available uplink transmitting energy and a second corresponding relation, wherein the second corresponding relation is the corresponding relation between the average transmitting power for transmitting the uplink signals in the first time period and the index of the average transmitting power for transmitting the uplink signals in the first time period.
Optionally, the first corresponding relationship may be expressed in various ways, for example, by a table.
In one example, the first corresponding relationship is represented by a table, and the table may include a corresponding relationship between an index of the uplink transmission energy and a range of the uplink transmission energy value (or RTE). As shown in table 1, an example of the first corresponding relationship is represented by a table, in which each index corresponds to a range of the uplink transmission energy value.
Table 1: uplink transmission energy index table
Index value | Range (unit) of |
0 | RTE<-32 |
1 | -32≤RTE<-30 |
2 | -30≤RTE<-28 |
3 | -28≤RTE<-26 |
… | … |
60 | 32≤RTE<34 |
61 | 34≤RTE<36 |
62 | 36≤RTE<38 |
63 | RTE≥38 |
Alternatively, the unit of the range of the uplink transmission energy in this application may be joule, or kilojoule, or milliwatt × millisecond (mW × ms), or watt × millisecond (W × ms), or kilowatt × millisecond (kW × ms), or watt × second (W × s), which is not limited in this application.
It is understood that the terminal device may determine the index of the available uplink transmission energy, that is, determine the first indication information, according to which range in table 1 the available uplink transmission energy is located in the first time period determined in S501.
For example, if the terminal device determines that the available uplink transmission energy value in the first time period is 35 through S501, it can be known from table 1 that the index value of the uplink transmission energy value corresponding to 35 is 61, that is, the first indication information is 61.
It should be noted that table 1 is only an example, and the table size of the corresponding relationship between the uplink transmission energy index and the uplink transmission energy value, the size of the numerical value (or called numerical range) in the table, and the unit of the numerical value in the table are not limited in the present invention.
In another example, the first corresponding relationship is represented by two tables, specifically, one table may include a corresponding relationship between an index of uplink transmission energy and an uplink transmission energy level, and the other table may include a corresponding relationship between an uplink transmission energy level and a range of an uplink transmission energy value (or RTE). As shown in table 2 and table 3, an example of the first corresponding relationship is represented by two tables, where each index in table 2 corresponds to one uplink transmission energy level, and each uplink transmission energy level in table 3 corresponds to a range of uplink transmission energy values.

63 | RTE_63 |
Table 3: example of correspondence between energy level and energy value range
Alternatively, the unit of the range of the uplink transmission energy in this application may be joule, or kilojoule, or milliwatt × millisecond (mW × ms), or watt × millisecond (W × ms), or kilowatt × millisecond (kW × ms), or watt × second (W × s), which is not limited in this application.
It can be understood that the terminal device may determine the energy level according to which range in table 3 the available uplink transmission energy in the first time period determined in S501 is located; and determining an index of available uplink transmission energy according to the determined energy level and the table 2, namely determining first indication information.
For example, if the terminal device determines that the available uplink transmission energy value in the first time period is 33 through S501, it can be known from table 3 that the energy level corresponding to 33 is RTE _60, and it can be known from table 2 that the index value of the uplink transmission energy value corresponding to energy level RTE _60 is 60, that is, the first indication information is 60.
It should be noted that, as shown in table 2 and table 3 above are only examples, the table size of the correspondence between the uplink transmission energy index and the uplink transmission energy level, the correspondence between the uplink transmission energy level and the uplink transmission energy value (or called energy range), the value size in each table, and the unit of the value in the table are not limited in the present invention. However, in the same application scenario, the table sizes corresponding to table 2 and table 3 are the same.
Optionally, the second correspondence may be represented in various ways, for example, by a table.
In one example, the second corresponding relationship is represented by a table, and the table may include a corresponding relationship between an index of Average Transmit Power (ATP) and an average transmit power of an uplink signal transmitted in the first time period. As shown in table 4, an example of the second correspondence relationship is represented by a table, in which each index corresponds to an average transmission power.
Table 4: index table of average transmitting power
Index value | Uplink average transmit power (dBm) |

… | … |
60 | 32≤ATP<34 |
61 | 34≤ATP<36 |
62 | 36≤ATP<38 |
63 | ATP≥38 |
It can be understood that the terminal device may determine, according to the available uplink transmission energy in the first time period determined in S501, an average transmission power for transmitting the uplink signal in the first time period according to the available uplink transmission energy; according to the determined average transmission power and table 4, which range the average transmission power is located in table 4 is determined, and an index value of the average transmission power, that is, the first indication information is determined.
For example, if the terminal device determines that the available uplink transmission energy value in the first time period is 96 through S501, and determines that the average transmission power value in the first time period is 32, it can be known from table 4 that the index value of the uplink average transmission power corresponding to 32 is 60, that is, the first indication information is 60.
It should be noted that table 4 is only an example, and the table size of the correspondence between the uplink average transmission power index and the uplink average transmission power and the value (or the value range) in the table are not limited in the present invention.
In another example, the second corresponding relationship is represented by two tables, specifically, one table may include a corresponding relationship between an index of the uplink average transmission power and the uplink average transmission power level, and the other table may include a corresponding relationship between the uplink average transmission power level and a range of the uplink average transmission power (or ATP). As shown in table 5 and table 6, an example of the second correspondence relationship is represented by two tables, where each index in table 5 corresponds to an uplink average transmission power level, and each uplink average transmission power level in table 6 corresponds to a range of uplink average transmission power values.

It can be understood that the terminal device may determine, according to the average transmission power corresponding to the available uplink transmission energy in the first time period determined in S501, an average transmission power level according to which range in table 6 the average transmission power is located; according to the determined average transmission power level and table 5, an index of the average transmission power level, i.e., the first indication information is determined.
For example, if the terminal device determines that the available uplink transmission energy value in the first time period is 96 through S501, and determines that the average transmission power value in the first time period is 32, it can be known from table 6 that the level of the uplink average transmission power corresponding to 32 is ATP _60, and the index value of the uplink average transmission power corresponding to ATP _60is 60 according to table 5, that is, the first indication information is 60.

However, in the same application scenario, the table sizes corresponding to table 5 and table 6 are the same.
Optionally, at least one of the first corresponding relationship and the second corresponding relationship is preset by a protocol or configured by a network device. Further, the network device may configure the above correspondence relationship through an RRC message or a broadcast message.
Optionally, the first indication information is carried in a MAC CE, or the first indication information is uplink control information UCI.
Further, UCI is carried on a physical uplink shared channel PUSCH or a physical uplink control channel PUCCH.
Further, when the UCI is carried on the PUSCH, the UCI is modulated and encoded in the same manner as the PUSCH. Resource Elements (REs) corresponding to the UCI and used for carrying the UCI may be determined based on a code rate compensation factor corresponding to the UCI, where the code rate compensation factor is indicated by DCI or configured for a higher layer parameter (e.g., RRC signaling or a parameter in RRC signaling). Optionally, the UCI may be carried on a data symbol after a first demodulation reference signal (DMRS) of the PUSCH; or, the UCI may be carried after a data symbol of the PUSCH for carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK) information; alternatively, the UCI may be carried after a data symbol used by the PUSCH to carry part or all of Channel State Information (CSI) information.
Further, the UCI may adopt a new UCI format, where the UCI format may refer to a type of information carried in the UCI and/or a size of information carried by the UCI. That is, the information carried by the UCI is information indicating available uplink transmission energy, and/or the size of the UCI is a first numerical value. The first value may be 6, 7 or 8, i.e., the size of the information carried by the UCI is 6, 7 or 8 bits.

case 3: the first field is a power headroom level, and the second field is the first indication information.
Further, the MAC CE further includes at least one of: a fifth field, a sixth field, or a seventh field; wherein the fifth field is used for indicating whether a Maximum Permissible Exposure (MPE) value is reported in the MAC CE, the sixth field is used for indicating an MPE value, and the seventh field is used for indicating P for calculating the power headroom level Cmax . It should be noted that, in case 1, the MAC CE may not include a field for indicating whether MPE is reported in the MAC CE, a field for indicating an MPE value, and P for indicating calculation of the power headroom level Cmax A field.

Optionally, there are various ways for the terminal device to determine the available uplink transmission time length, which is described as follows in a way c1:
mode c1: the terminal device determines the number of time units in a first time period in which the available uplink transmission time length is a time window, wherein the terminal device can use a first preset power value to transmit an uplink signal based on the available uplink transmission energy.
In this way, the terminal device determines, according to the available uplink transmission energy in the first time period and the first preset power value, the number of time units in the first time period of the time window, where the terminal device can transmit the uplink signal using the first preset power value.
Alternatively, the determination of the available uplink transmission energy may be performed in the same manner as the determination of the available uplink transmission energy in step S501.
Further, the length of the available uplink transmission time is equal to a ratio between the available uplink transmission energy in the first time period and the first preset power value.

Alternatively, the maximum transmission power of the terminal device specified in the standard may be 23dBm, 26dBm, or 14dBm.
Alternatively, the time units may be subframes, slots, symbols, or time units of other granularity. For example, as shown in fig. 8a, the terminal device has 10 time units in total in the time window, which are numbered from 0 to 9, and the terminal device determines that the time during which the available uplink transmission energy can support signal transmission at the first preset power in the first time period is 3 time units, and thus determines that the available uplink transmission time length is 3 time units.
It should be noted that, if the ratio between the available uplink transmission energy and the first preset power value in the first time period is not a time unit of an integral multiple, the value may be corrected by rounding up or rounding down, which is not limited in this application. For example, if the terminal device determines that the ratio between the available uplink transmission energy and the first preset power value in the first time period is 3.7 time units, if rounding up is adopted, the available uplink transmission time length is 4 time units; if rounding-down is adopted, the available uplink transmission time length is 3 time units.

and determining an index of the ratio of the available uplink transmission time length to the preset time length according to the available uplink transmission time length and a fourth corresponding relationship, wherein the fourth corresponding relationship is the corresponding relationship between the ratio of the available uplink transmission time length to the preset time length and the index of the ratio of the available uplink transmission time length to the preset time length.

Table 7: time unit number index table
Index value | Number of |
0 | 0 |
1 | 1 |
2 | 2 |
3 | 3 |
… | |
60 | 60 |
61 | 61 |
62 | 62 |
63 | 63 |
It can be understood that the terminal device determines an index of the number of time units, that is, determines the second indication information according to which range in table 7 the number of time units of the uplink signal transmitted by the terminal device using the first preset power value in the first time period of the time window determined in S701 is located.
For example, if the terminal device determines that the number of time units for transmitting the uplink signal using the first preset power value in the first time period of the time window is 3 through S701, it can be known from table 7 that the index value corresponding to 3 is 3, that is, the second indication information is 3.
It should be noted that table 7 is only an example, and the table size of the correspondence between the index of the time unit number and the time unit number, and the size of the value (or the range of the value) in the table are not limited in the present invention.
Optionally, there are multiple ways to represent the fourth correspondence, in an example, the fourth correspondence is represented by a table, where the table may include a correspondence between a ratio between the number of time units used by the terminal device to transmit the uplink signal using the first preset power value in the first time period of the time window and the number of all time units included in the preset time period, and an index value, as shown in table 8, each index in the table corresponds to a ratio, quantization is performed at intervals of 2% in the table, quantization may be performed by using table 8 as an index table including 50 ratios of the number of time units and 14 reserved entries, and accordingly, the length of the second indication information is 6 bits.
Table 8: time unit quantity ratio index table
Index value | Ratio of number of |
0 | 0 |
1 | 0.02 |
2 | 0.04 |
3 | 0.06 |
… | … |
29 | 0.3 |
… | … |
48 | 0.98 |
49 | 1 |
50-63 | Reservation |
It can be understood that, according to the ratio between the number of time units, in the first time period of the time window determined in S701, of the uplink signal sent by the terminal device using the first preset power value and the number of all time units included in the preset time period, the terminal device determines the corresponding index value according to which range the ratio is located in table 8.
For example, if the terminal device determines that the ratio between the number of time units, in which the terminal device sends the uplink signal by using the first preset power value, in the first time period of the time window and the number of all time units included in the preset time period is 0.3, it can be known from table 8 that the index value corresponding to 0.3 is 29, that is, the second indication information is 29.
For another example, if the terminal device determines that the ratio between the number of time units, in which the terminal device sends the uplink signal using the first preset power value, in the first time period of the time window and the number of all time units included in the preset time period is 0.05, as can be seen from table 8, the index value corresponding to 0.05 is 3, that is, the second indication information is 3.
It should be noted that, as the above table 8 is only an example, the table size of the time unit quantity ratio index table, and the value size in the table (for example, how many intervals the values are quantized) are not limited in this regard.

Resource Elements (REs) corresponding to the UCI and used for carrying the UCI may be determined based on a code rate compensation factor corresponding to the UCI, where the code rate compensation factor is indicated by DCI or configured for a higher layer parameter (e.g., RRC signaling or a parameter in RRC signaling). Optionally, the UCI may be carried on a data symbol after a first demodulation reference signal (DMRS) of the PUSCH; or, the UCI may be carried after a data symbol of the PUSCH for carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK) information; alternatively, the UCI may be carried after a data symbol used by the PUSCH to carry part or all of Channel State Information (CSI) information.
Further, the UCI may adopt a new UCI format, where the UCI may refer to a type of information carried in the UCI and/or a size of information carried by the UCI. That is, the information carried by the UCI is information for indicating available uplink transmission energy, and/or the size of the UCI is a first value, and the first value may be 6, 7, or 8, that is, the UCI includes 6, 7, or 8 bits.
Further, when the second indication information is carried in the MAC CE, the MAC CE includes a third field and a fourth field, where:
a third field is reserved bits, and a fourth field indicates the second indication information; or,
when the third field is the first state value, the fourth field indicates the second indication information; when the third field is a second state value, the fourth field indicates the power headroom level; or,
a third field indicates a power headroom level and a fourth field indicates the second indication information.
The format of the MAC CE is designed as the MAC CE format in S502, and it should be noted that if the MAC CE format is used to carry the second indication information, the "first indication information" in the MAC CE format in S502 is replaced by the "second indication information", that is, the MAC CE format carrying the second indication information can be obtained, and other descriptions may refer to S502, which is not described herein again.
