[0003] In a sub-band full duplex (SBFD) system, network devices can simultaneously transmit and receive using different sub-bands within a single frequency band / carrier / bandwidth part (BWP), with the sub-bands used for transmission and reception not overlapping. For example, a network device can configure uplink sub-bands for downlink symbols or flexible symbols. Symbols configured with uplink sub-bands are SBFD symbols, and terminals that recognize SBFD can perform uplink transmissions on these sub-bands. Symbols not configured with uplink sub-bands are non-SBFD symbols, and all terminals transmit in the direction of the configured symbols.

[0004] In an SBFD system, to reduce interference between uplink and downlink subbands, the transmit power of the channel on SBFD symbols and non-SBFD symbols may be different. Therefore, how to calculate the transmit power of the channel during random access is a technical problem that needs to be solved urgently. Summary of the Invention

[0157] In the embodiments of the present disclosure, the term "at least one (item)" refers to one (item) or more (items), and "more than one (item)" refers to two (items) or more than two (items), and other quantifiers are similar.

[0158] In the embodiments of the present disclosure, the terms "first," "second," "third," "fourth," and "fifth" are used only for illustration and to distinguish the objects being described.

They do not constitute any limitation on the embodiments of the present disclosure. For example, the first PRACH transmit power is the transmit power of the current PRACH transmission, and the second PRACH transmit power is the transmit power of the PRACH transmission immediately preceding the current PRACH transmission. The use of terms such as "first" and "second" is only to distinguish between different PRACH transmit powers, and does not indicate a difference in size, priority, or importance between the two PRACH transmit powers.

[0159] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure.

In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network.

[0165] Figure 1 is a schematic diagram of an architecture of a communication system provided by an embodiment of the present disclosure. As shown in Figure 1, the architecture includes a network device 101 and a terminal 102. The network device 101 and the terminal 102 can perform uplink communication and downlink communication.

[0166] In order to explain the present disclosure more clearly, the related technologies involved in the present disclosure are introduced below.

[0167] 1. Duplex mode

[0168] 5G NR supports both time division duplex (TDD) and frequency domain duplex (FDD) modes. TDD mode allows network devices to transmit and receive at different times on the same frequency channel (i.e., carrier), distinguishing uplink and downlink transmission resources by time. FDD mode allows network devices to transmit and receive simultaneously on different frequency channels, distinguishing uplink and downlink transmission resources by frequency.

[0169] To enhance uplink (UL) coverage and reduce uplink latency, the SBFD mode was introduced. In SBFD mode, network devices can simultaneously transmit and receive using different subbands within the frequency band / carrier / BWP, with no overlap between the subbands used for transmission and reception. As shown in Figure 2, the uplink subbands exist in some symbols and do not overlap with other frequency domain resources.

[0170] Network devices can configure uplink subbands for downlink (DL) symbols or flexible symbols in the TDD-UL-DL-ConfigCommon configuration. Symbols configured with uplink subbands are SBFD symbols, and SBFD-aware terminals (SBFD-aware UEs) can perform uplink transmissions on the subbands. Symbols not configured with uplink subbands (including symbols configured as uplink in TDD-UL-DL-ConfigCommon) are non-SBFD symbols, and all terminals transmit in the configured symbol direction.

[0171] 2. PRACH transmit power

[0172] The physical layer protocol defines the calculation method for the transmit power of the PRACH channel transmitted in an RO as follows: PRACH,b,f,c (i) = min{P CMAX,f,c (i),P PRACH,target,f,c +PL b,f,c}

[0173] Among them, P CMAX,f,c (i) is the maximum transmit power of the terminal defined by RAN4, P PRACH,target,f,c is the PRACH target received power, PL b,f,c It is the path loss determined based on the DL reference signal (RS) associated with the PRACH transmission.

[0174] The calculation method of PRACH target receive power is defined in the MAC layer protocol as: preambleReceivedTargetPower+DELTA_PREAMBLE+ (PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP+POWER_OFFSET_2STEP_RA

[0175] Among them, preambleReceivedTargetPower is the target receive power configured on the network side, DELTA_PREAMBLE is a protocol predefined parameter bound to the PRACH format, PREAMBLE_POWER_RAMPING_COUNTER is the number of power ramps performed during the current random access process according to certain rules, PREAMBLE_POWER_RAMPING_STEP is the amplitude of each power ramp configured on the network side, and POWER_OFFSET_2STEP_RA is the power offset value that needs to be calculated after two-step random access falls back to four-step random access.

[0176] 3. Physical uplink shared channel (PUSCH) transmit power

[0177] The physical layer protocol defines the calculation method for the transmit power of the PUSCH channel carrying Msg3 in an RO as follows:

[0178] Among them, P CMAX,f,c (i) is the maximum transmit power of the terminal defined by RAN4, P O_PUSCH,b,f,c (j) is P O_NOMINAL,PUSCH,f,c (j) and P O_UE_PUSCH,b,f,c (j), for the PUSCH carrying Msg3 in the random access process, P O_UE_PUSCH,b,f,c (j) = 0, P O_NOMINAL,PUSCH,f,c (0) = P O_PRE +Δ PREAMBLE,Msg3 Among them, P O_PRE The target received power of the preamble configured on the network side, Δ PREAMBLE,Msg3 It is the gap between the PUSCH transmit power and the preamble transmit power of Msg3 carried by msg3-DeltaPreamble or deltaPreamble configured by the network side. If both msg3-DeltaPreamble and deltaPreamble are configured, the gap is 0. is the number of resource blocks occupied by PUSCH bandwidth, α b,f,c (j) is the path loss coefficient, PL b,f,c (q d ) is the downlink path loss evaluated by the terminal through the reference signal, Δ TF,b,f,c (i) is the power scaling factor for PUSCH single-layer transmission, f b,f,c (i, l) is the power adjustment value indicated by the power control signaling.

[0179] In an SBFD system, to reduce interference between uplink and downlink subbands, the transmit power of the channel on SBFD symbols and non-SBFD symbols may be different. Therefore, how to calculate the transmit power of the channel during random access is a technical problem that needs to be solved urgently.

[0180] Based on the problems in the related art, the present disclosure proposes the following technical concept: the network device configures two sets of power parameters for the terminal, one for SBFD symbols and the other for non-SBFD symbols. The terminal can accurately calculate the channel transmission power during random access based on the two sets of power parameters, thereby reducing channel interference on different symbol types.

[0181] The following describes the method for determining the transmit power provided by the present disclosure in conjunction with embodiments.

[0182] FIG3 is a flowchart of a method for determining transmit power according to an embodiment of the present disclosure. As shown in FIG3 , the method is applied to a terminal and includes:

[0183] S301: Receive configuration information, where the configuration information is used to indicate power parameters on SBFD symbols and power parameters on non-SBFD symbols.

[0184] The power parameter may include at least one of the following: target received power preambleReceivedTargetPower, power ramping step size PREAMBLE_POWER_RAMPING_STEP, transmission power increment msg3-DeltaPreamble or deltaPreamble.

[0185] The following describes the contents of the configuration information in two situations.

[0186] 1. The configuration information includes the power parameters on SBFD symbols and the power parameters on non-SBFD symbols.

[0187] In this case, the configuration information may include at least one of the following:

[0188] (1) A third target received power and a fourth target received power. The third target received power is the target received power on SBFD symbols, and the fourth target received power is the target received power on non-SBFD symbols.

[0189] (2) A first power ramp step and a second power ramp step. The first power ramp step is the power ramp step on the SBFD symbol, and the second power ramp step is the power ramp step on the non-SBFD symbol.

[0190] (3) A first transmission power increment and a second transmission power increment. The first transmission power increment is the transmission power increment on the SBFD symbol, and the second transmission power increment is the transmission power increment on the non-SBFD symbol.

[0191] 2. The configuration information includes a power parameter on one symbol and an offset value of the power parameter on two symbols.

[0192] In this case, the configuration information may include at least one of the following:

[0193] (1) A fifth target received power and a target received power offset value. The fifth target received power is the target received power on an SBFD symbol or a non-SBFD symbol. The target received power offset value is the offset value between the target received power on an SBFD symbol and the target received power on a non-SBFD symbol.

[0194] If the fifth target received power is the target received power on the SBFD symbol, then the target received power on the non-SBFD symbol = the fifth target received power + the target received power offset value, or the target received power on the non-SBFD symbol = the fifth target received power - the target received power offset value.

[0195] If the fifth target received power is the target received power on the non-SBFD symbol, then the target received power on the SBFD symbol = the fifth target received power + the target received power offset value, or the target received power on the SBFD symbol = the fifth target received power - the target received power offset value.

[0196] (2) A third power ramp step and a power ramp offset value. The third power ramp step is a power ramp step on an SBFD symbol or a non-SBFD symbol. The power ramp offset value is an offset value between the power ramp step on an SBFD symbol and the power ramp step on a non-SBFD symbol.

[0197] If the third power climb step size is the power climb step size on the SBFD symbol, then the power climb step size on the non-SBFD symbol = the third power climb step size + the power climb step size offset value, or the power climb step size on the non-SBFD symbol = the third power climb step size - the power climb step size offset value.

[0198] If the third power climb step size is the power climb step size on a non-SBFD symbol, then the power climb step size on the SBFD symbol = the third power climb step size + the power climb step size offset value, or the power climb step size on the SBFD symbol = the third power climb step size - the power climb step size offset value.

[0199] (3) A third power transmission increment and a power transmission increment offset value. The third power transmission increment is a power transmission increment on an SBFD symbol or a non-SBFD symbol. The power transmission increment offset value is an offset value between the power transmission increment on the SBFD symbol and the power transmission increment on the non-SBFD symbol.

[0200] If the third power transmission increment is the power transmission increment on the SBFD symbol, then the power transmission increment on the non-SBFD symbol = the third power transmission increment + the power transmission increment offset value, or the power transmission increment on the non-SBFD symbol = the third power transmission increment - the power transmission increment offset value.

[0201] If the third power transmission increment is the power transmission increment on a non-SBFD symbol, then the power transmission increment on the SBFD symbol = the third power transmission increment + the power transmission increment offset value, or the power transmission increment on the SBFD symbol = the third power transmission increment - the power transmission increment offset value.

[0202] S302: Determine the transmit power during the random access process according to the configuration information.

[0203] The transmit power during the random access process may include a first PRACH transmit power or a PUSCH transmit power. The first PRACH transmit power may be the transmit power of the current PRACH transmission, which refers to the PRACH transmission in the current RACH attempt; that is, the first PRACH transmit power may be the transmit power of the PRACH to be transmitted. The PUSCH transmit power may be the transmit power of the current PUSCH transmission carrying message 3, which refers to the PUSCH transmission carrying message 3 in the current RACH attempt; that is, the PUSCH transmit power may be the transmit power of the PUSCH carrying message 3 to be transmitted.

[0204] After determining the transmit power during the random access process, the transmit power may be used to transmit the channel during the random access process. For example, if the transmit power during the random access process is the first PRACH transmit power, the first PRACH transmit power may be used to transmit the current PRACH; if the transmit power during the random access process is the PUSCH transmit power, the PUSCH currently carrying message 3 may be transmitted using the PUSCH transmit power.

[0205] When the transmission power in the random access process is the first PRACH transmission power, the following multiple situations can be used to illustrate how to determine the first PRACH transmission power.

[0206] 1. The configuration information is used to indicate the power ramp step size on SBFD symbols and the power ramp step size on non-SBFD symbols.

[0207] In this case, the ramp-up power may be determined according to the configuration information; and the first PRACH transmit power may be determined according to the ramp-up power.

[0208] The ramp-up power may be the ramp-up power of the current PRACH transmission.

[0209] After the ramp-up power is determined, the first PRACH transmit power may be calculated with reference to the aforementioned method for calculating the PRACH transmit power.

[0210] Below, we explain how to determine the climbing power in three ways.

[0211] Method 1: Obtain a first power climb number and a second power climb number, where the first power climb number is the power climb number for transmitting PRACH on SBFD symbols, and the second power climb number is the power climb number for transmitting PRACH on non-SBFD symbols; determine the climb power based on the first power climb number, the power climb step size on SBFD symbols, the second power climb number, and the power climb step size on non-SBFD symbols.

[0212] In this manner, two power ramp counts may be used to obtain the first power ramp times and the second power ramp times respectively.

[0213] The two power ramp counts may be newly configured; or the power ramp count configured in the related art may be reused and a new power ramp count may be introduced.

[0214] In this way, the following three cases are used to explain how to determine the climbing power.

[0215] ① When the configuration information includes the power climbing step on the SBFD symbol (i.e., the first power climbing step) and the power climbing step on the non-SBFD symbol (i.e., the second power climbing step), the climbing power can be determined based on the first power climbing number, the first power climbing step, the second power climbing number and the first power climbing step.

[0216] That is, the climb power can be determined by the following formula:

[0217] Climbing power=(first power climbing times-1)×first power climbing step length+(second power climbing times-1)×second power climbing step length).

[0218] ② When the configuration information includes the power climb step size (i.e., the third power climb step size) and the power climb step size offset value on the SBFD symbol, the climb power can be determined based on the first power climb number, the third power climb step size, the second power climb number, and the power climb step size offset value.

[0219] That is, the climb power can be determined by the following formula:

[0220] Climb power=(first power climb times-1)×third power climb step+(second power climb times-1)×(third power climb step+power climb step offset).

[0221] Alternatively, ramp power=(first power ramp times−1)×third power ramp step length+(second power ramp times−1)×(third power ramp step length−power ramp step length offset value).

[0222] ③ When the configuration information includes the power climb step size on the non-SBFD symbol (i.e., the third power climb step size) and the power climb step size offset value, the climb power can be determined based on the first power climb number, the third power climb step size, the second power climb number, and the power climb step size offset value.

[0223] That is, the climb power can be determined by the following formula:

[0224] Climb power=(first power climb times-1)×(third power climb step+power climb step offset)+(second power climb times-1)×third power climb step.

[0225] Alternatively, ramp power=(first power ramp times-1)×(third power ramp step-power ramp step offset)+(second power ramp times-1)×third power ramp step.

[0226] Method 2: Obtain a first power climb number and a second power climb number, where the first power climb number is the power climb number for transmitting PRACH on SBFD symbols, and the second power climb number is the power climb number for transmitting PRACH on non-SBFD symbols; determine the climb power based on the power climb number and power climb step corresponding to the first target symbol type.

[0227] The first target symbol type is a symbol type corresponding to the current PRACH transmission, and the first target symbol type is an SBFD symbol or a non-SBFD symbol.

[0228] It should be noted that, when determining the symbol type corresponding to the current PRACH transmission, only whether the time domain resource of the current PRACH transmission is on an SBFD symbol or a non-SBFD symbol is considered.

[0229] In this manner, two power ramp counts may be used to obtain the first power ramp times and the second power ramp times respectively.

[0230] The two power ramp counts may be newly configured; or the power ramp count configured in the related art may be reused and a new power ramp count may be introduced.

[0231] In this way, the following three cases are used to explain how to determine the climbing power.

[0232] ① When the configuration information includes the power climbing step on the SBFD symbol (i.e., the first power climbing step) and the power climbing step on the non-SBFD symbol (i.e., the second power climbing step), the climbing power can be determined based on the number of power climbs and the power climbing step corresponding to the first target symbol type.

[0233] If the first target symbol type is an SBFD symbol, the ramp power can be determined based on the first power ramp times and the first power ramp step size. That is, the ramp power can be determined using the following formula:

[0234] Climbing power = (first power climbing times - 1) × first power climbing step length.

[0235] If the first target symbol type is a non-SBFD symbol, the ramp power can be determined based on the second power ramp times and the second power ramp step size. That is, the ramp power can be determined using the following formula:

[0236] Climbing power = (second power climbing times - 1) × second power climbing step length.

[0237] ② When the configuration information includes the power climb step size (i.e., the third power climb step size) and the power climb step size offset value on the SBFD symbol, the climb power can be determined based on the power climb times and the power climb step size corresponding to the first target symbol type.

[0238] If the first target symbol type is an SBFD symbol, the ramp power can be determined based on the first power ramp times and the third power ramp step size. That is, the ramp power can be determined using the following formula:

[0239] Climbing power = (first power climb times - 1) × third power climb step length.

[0240] If the first target symbol type is a non-SBFD symbol, the ramp power can be determined based on the second power ramp number, the third power ramp step, and the power ramp step offset. That is, the ramp power can be determined using the following formula:

[0241] Climb power = (second power climb times - 1) × (third power climb step + power climb step offset); or,

[0242] Climb power = (second power climb times - 1) × (third power climb step - power climb step offset).

[0243] ③ When the configuration information includes the power climb step size on the non-SBFD symbol (i.e., the third power climb step size) and the power climb step size offset value, the climb power can be determined according to the power climb times and power climb step size corresponding to the first target symbol type.

[0244] If the first target symbol type is an SBFD symbol, the ramp power can be determined based on the first power ramp number, the third power ramp step, and the power ramp step offset. That is, the ramp power can be determined using the following formula:

[0245] Climb power = (first power climb times - 1) × (third power climb step + power climb step offset); or,

[0246] Climb power = (first power climb times - 1) × (third power climb step - power climb step offset).

[0247] If the first target symbol type is a non-SBFD symbol, the ramp power can be determined based on the second power ramp times and the third power ramp step size. That is, the ramp power can be determined using the following formula:

[0248] Climbing power = (second power climb times - 1) × third power climb step length.

[0249] Method 3: Obtain the total number of power ramps for transmitting PRACH on SBFD symbols and non-SBFD symbols; determine the ramp power according to the total number of power ramps and the power ramp step corresponding to the fourth target symbol type.

[0250] The fourth target symbol type is a symbol type corresponding to a current PRACH transmission or a symbol type corresponding to a first PRACH transmission, and the fourth target symbol type is an SBFD symbol or a non-SBFD symbol.

[0251] It should be noted that when determining the symbol type corresponding to the current PRACH transmission, only whether the time domain resources of the current PRACH transmission are on SBFD symbols or non-SBFD symbols is considered. When determining the symbol type corresponding to the first PRACH transmission, only whether the time domain resources of the first PRACH transmission are on SBFD symbols or non-SBFD symbols is considered.

[0252] The symbol type corresponding to the first PRACH transmission and the symbol type corresponding to the current PRACH transmission may be the same or different.

[0253] In addition, if the terminal supports attempting multiple PRACH transmissions on one symbol type and then falling back to attempting PRACH transmission on another symbol type, the fourth target symbol type may be the symbol type corresponding to the PRACH transmission before falling back.

[0254] For example, if the terminal attempts PRACH transmission on SBFD symbols for multiple times and then falls back to attempting PRACH transmission on non-SBFD symbols, the fourth target symbol type may be an SBFD symbol.

[0255] In this way, a power ramp count can be used to obtain the total number of power ramps.

[0256] The power ramp count configured in the related art may be reused to obtain the total number of power ramps, or a new power ramp count may be introduced to obtain the total number of power ramps.

[0257] In this way, the following three cases are used to explain how to determine the climbing power.

[0258] ① When the configuration information includes the power climbing step on the SBFD symbol (i.e., the first power climbing step) and the power climbing step on the non-SBFD symbol (i.e., the second power climbing step), the climbing power can be determined based on the total number of power climbs and the power climbing step corresponding to the fourth target symbol type.

[0259] If the fourth target symbol type is an SBFD symbol, the ramp power can be determined based on the total number of power ramps and the first power ramp step size. That is, the ramp power can be determined using the following formula:

[0260] Climb power = (total number of power climbs - 1) × first power climb step size.

[0261] If the fourth target symbol type is a non-SBFD symbol, the ramp power can be determined based on the total number of power ramps and the second power ramp step size. That is, the ramp power can be determined using the following formula:

[0262] Climb power = (total number of power climbs - 1) × second power climb step size.

[0263] ② When the configuration information includes the power climb step on the SBFD symbol (i.e., the third power climb step) and the power climb step offset value, the climb power can be determined based on the total number of power climbs and the power climb step corresponding to the fourth target symbol type.

[0264] If the fourth target symbol type is an SBFD symbol, the ramp power can be determined based on the total number of power ramps and the third power ramp step size. That is, the ramp power can be determined using the following formula:

[0265] Climb power = (total number of power climbs - 1) × third power climb step.

[0266] If the fourth target symbol type is a non-SBFD symbol, the ramp power can be determined based on the total number of power ramps, the third power ramp step, and the power ramp step offset. That is, the ramp power can be determined using the following formula:

[0267] Climb power = (total number of power climbs - 1) × (third power climb step + power climb step offset); or,

[0268] Climb power = (total number of power climbs - 1) × (third power climb step - power climb step offset).

[0269] ③ When the configuration information includes the power climb step size on the non-SBFD symbol (i.e., the third power climb step size) and the power climb step size offset value, the climb power can be determined based on the total number of power climbs and the power climb step size corresponding to the fourth target symbol type.

[0270] If the fourth target symbol type is an SBFD symbol, the ramp power can be determined based on the total number of power ramps, the third power ramp step, and the power ramp step offset. That is, the ramp power can be determined using the following formula:

[0271] Climb power = (total number of power climbs - 1) × (third power climb step + power climb step offset); or,

[0272] Climb power = (total number of power climbs - 1) × (third power climb step - power climb step offset).

[0273] If the fourth target symbol type is a non-SBFD symbol, the ramp power can be determined based on the total number of power ramps and the third power ramp step size. That is, the ramp power can be determined using the following formula:

[0274] Climb power = (total number of power climbs - 1) × third power climb step.

[0275] In this case, when the reference signal used for the current PRACH transmission is the same as the reference signal used for the previous PRACH transmission, and / or the symbol type corresponding to the current PRACH transmission is the same as the symbol type corresponding to the previous PRACH transmission, the total number of power ramps corresponding to the current PRACH transmission is the sum of the total number of power ramps corresponding to the previous PRACH transmission and 1.

[0276] The reference signal may be a synchronization signal block SSB or a channel state information reference signal CSI-RS.

[0277] For example, when counting the total number of power climbs, the existing mechanism can be referred to, that is, as long as the synchronization signal block (SSB) index used by the current PRACH transmission is the same as the SSB index used by the previous PRACH transmission, it is counted once, that is, the total number of power climbs corresponding to the current RACH transmission is equal to the total number of power climbs corresponding to the previous PRACH transmission plus 1.

[0278] As another example, when counting the total number of power climbs, if the SSB index used in the current PRACH transmission is the same as the SSB index used in the previous PRACH transmission, and the symbol type corresponding to the current PRACH transmission is the same as the symbol type corresponding to the previous PRACH transmission, then the count is one, that is, the total number of power climbs corresponding to the current RACH transmission is equal to the total number of power climbs corresponding to the previous PRACH transmission plus 1.

[0279] 2. The configuration information is used to indicate the target received power on SBFD symbols and the target received power on non-SBFD symbols.

[0280] In this case, the target received power corresponding to the first target symbol type may be determined as the first target received power according to the configuration information; and the first PRACH transmit power may be determined according to the first target received power.

[0281] The first target received power may be the target received power of the current PRACH transmission.

[0282] After the first target received power is determined, the first PRACH transmit power may be calculated with reference to the aforementioned calculation method of the PRACH transmit power.

[0283] In this case, three methods are described below to explain how to determine the first target received power.

[0284] ① When the configuration information includes the target received power on the SBFD symbol (i.e., the third target received power) and the target received power on the non-SBFD symbol (i.e., the fourth target received power), the target received power corresponding to the first target symbol type in the configuration information can be determined as the first target received power.

[0285] If the first target symbol type is an SBFD symbol, the third target received power may be determined as the first target received power.

[0286] If the first target symbol type is a non-SBFD symbol, the fourth target received power may be determined as the first target received power.

[0287] ② When the configuration information includes the target received power on the SBFD symbol (i.e., the fifth target received power) and the target received power offset value, the target received power on the non-SBFD symbol can be determined based on the fifth target received power and the target received power offset value, and the target received power corresponding to the first target symbol type can be determined as the first target received power.

[0288] If the first target symbol type is an SBFD symbol, the fifth target received power may be determined as the first target received power.

[0289] If the first target symbol type is a non-SBFD symbol, it may be determined that the first target received power = the fifth target received power + the target received power offset value, or the first target received power = the fifth target received power - the target received power offset value.

[0290] ③ When the configuration information includes the target received power on the non-SBFD symbol (i.e., the fifth target received power) and the target received power offset value, the target received power on the SBFD symbol can be determined based on the fifth target received power and the target received power offset value, and the target received power corresponding to the first target symbol type can be determined as the first target received power.

[0291] If the first target symbol type is an SBFD symbol, it may be determined that the first target received power = the fifth target received power + the target received power offset value, or the first target received power = the fifth target received power - the target received power offset value.

[0292] If the first target symbol type is a non-SBFD symbol, the fifth target received power may be determined as the first target received power.

[0293] 3. The configuration information is used to indicate the power ramp step size and target received power on SBFD symbols, as well as the power ramp step size and target received power on non-SBFD symbols.

[0294] In this case, the ramp-up power may be determined based on the configuration information; the first target receive power may be determined based on the first target symbol type and the configuration information; and the first PRACH transmit power may be determined based on the ramp-up power and the first target receive power.

[0295] The climbing power can be determined by referring to the method in case 1, and the first target received power can be determined by referring to the method in case 2, which will not be repeated here.

[0296] After the ramp-up power and the first target received power are determined, the first PRACH transmit power may be calculated with reference to the aforementioned calculation method for the PRACH transmit power.

[0297] It should be noted that the first PRACH transmit power in the embodiment of the present disclosure may be the transmit power of a single PRACH transmission, or the transmit power of any one PRACH transmission in a process of multiple PRACH transmissions, wherein multiple PRACH transmissions may also be referred to as repeated PRACH transmissions.

[0298] When the transmission power in the random access process is the PUSCH transmission power, the following multiple situations can be used to illustrate how to determine the PUSCH transmission power.

[0299] 1. The configuration information is used to indicate the target received power on SBFD symbols and the target received power on non-SBFD symbols.

[0300] In this case, the target received power corresponding to the second target symbol type may be determined as the second target received power according to the configuration information; and the PUSCH transmit power may be determined according to the second target received power.

[0301] The second target symbol type is the symbol type corresponding to the current PUSCH transmission carrying message 3 or the symbol type corresponding to the current PRACH transmission, and the second target symbol type is an SBFD symbol or a non-SBFD symbol.

[0302] It should be noted that when determining the symbol type corresponding to the current PUSCH transmission carrying message 3, only whether the time domain resource of the current PUSCH transmission carrying message 3 is on an SBFD symbol or a non-SBFD symbol is considered. When determining the symbol type corresponding to the current PRACH transmission, only whether the time domain resource of the current PRACH transmission is on an SBFD symbol or a non-SBFD symbol is considered.

[0303] The second target received power may be the target received power of the PUSCH transmission currently carrying message 3 .

[0304] After the second target received power is determined, the PUSCH transmit power may be calculated with reference to the aforementioned method for calculating the PUSCH transmit power.

[0305] In this case, three methods are described below to explain how to determine the second target received power.

[0306] ① When the configuration information includes the target received power on the SBFD symbol (i.e., the third target received power) and the target received power on the non-SBFD symbol (i.e., the fourth target received power), the target received power corresponding to the second target symbol type in the configuration information can be determined as the second target received power.

[0307] If the second target symbol type is an SBFD symbol, the third target received power may be determined as the second target received power.

[0308] If the second target symbol type is a non-SBFD symbol, the fourth target received power may be determined as the second target received power.

[0309] ② When the configuration information includes the target received power on the SBFD symbol (i.e., the fifth target received power) and the target received power offset value, the target received power on the non-SBFD symbol can be determined based on the fifth target received power and the target received power offset value, and the target received power corresponding to the second target symbol type can be determined as the second target received power.

[0310] If the second target symbol type is an SBFD symbol, the fifth target received power may be determined as the second target received power.

[0311] If the second target symbol type is a non-SBFD symbol, the second target received power may be determined as follows: the fifth target received power + the target received power offset; or the second target received power = the fifth target received power - the target received power offset.

[0312] ③ When the configuration information includes the target received power on the non-SBFD symbol (i.e., the fifth target received power) and the target received power offset value, the target received power on the SBFD symbol can be determined based on the fifth target received power and the target received power offset value, and the target received power corresponding to the second target symbol type can be determined as the second target received power.

[0313] If the second target symbol type is an SBFD symbol, it may be determined that the second target received power = the fifth target received power + the target received power offset value, or the second target received power = the fifth target received power - the target received power offset value.

[0314] If the second target symbol type is a non-SBFD symbol, the fifth target received power may be determined as the first target received power.

[0315] 2. The configuration information is used to indicate the transmission power increment on the SBFD symbol and the transmission power increment on the non-SBFD symbol.

[0316] In this case, the transmission power increment corresponding to the third target symbol type may be determined as the target transmission power increment according to the configuration information; and the PUSCH transmit power may be determined according to the target transmission power increment.

[0317] The third target symbol type is the symbol type corresponding to the PUSCH transmission currently carrying message 3, and the third target symbol type is an SBFD symbol or a non-SBFD symbol.

[0318] The target transmission power increment may be a transmission power increment of the PUSCH currently carrying message 3 .

[0319] After the target transmission power increment is determined, the PUSCH transmit power may be calculated by referring to the aforementioned calculation method of the PUSCH transmit power.

[0320] In this case, three methods are described below to describe how to determine the target transmission power increment.

[0321] ① When the configuration information includes the transmission power increment on the SBFD symbol (i.e., the first transmission power increment) and the transmission power increment on the non-SBFD symbol (i.e., the second transmission power increment), the transmission power increment corresponding to the third target symbol type in the configuration information can be determined as the target transmission power increment.

[0322] If the third target symbol type is an SBFD symbol, the first transmission power increment may be determined as the target transmission power increment.

[0323] If the third target symbol type is a non-SBFD symbol, the second transmission power increment may be determined as the target transmission power increment.

[0324] ② When the configuration information includes the transmission power increment on the SBFD symbol (i.e., the third transmission power increment) and the transmission power increment offset value, the transmission power increment on the non-SBFD symbol can be determined based on the third transmission power increment and the transmission power increment offset value, and the transmission power increment corresponding to the third target symbol type is determined as the target transmission power increment.

[0325] If the third target symbol type is an SBFD symbol, the third transmission power increment may be determined as the target transmission power increment.

[0326] If the third target symbol type is a non-SBFD symbol, the target transmission power increment may be determined as follows: the third transmission power increment + the transmission power increment offset; or the target transmission power increment = the third transmission power increment - the transmission power increment offset.

[0327] ③ When the configuration information includes the transmission power increment on the non-SBFD symbol (i.e., the third transmission power increment) and the transmission power increment offset value, the transmission power increment on the SBFD symbol can be determined based on the third transmission power increment and the transmission power increment offset value, and the transmission power increment corresponding to the third target symbol type is determined as the target transmission power increment.

[0328] If the third target symbol type is an SBFD symbol, the target transmission power increment may be determined as follows: the third transmission power increment + the transmission power increment offset value; or the target transmission power increment = the third transmission power increment - the transmission power increment offset value.

[0329] If the third target symbol type is a non-SBFD symbol, the third transmission power increment may be determined as the target transmission power increment.

[0330] It should be noted that if the network device is not configured with a transmission power increment on SBFD symbols, the transmission power increment on non-SBFD symbols may be used to determine the PUSCH transmit power.

[0331] 3. The configuration information is used to indicate the target receive power and transmit power increment on SBFD symbols, as well as the target receive power and transmit power increment on non-SBFD symbols.

[0332] In this case, the target receiving power corresponding to the second target symbol type can be determined as the second target receiving power according to the configuration information; the transmission power increment corresponding to the third target symbol type can be determined as the target transmission power increment according to the configuration information; and the PUSCH transmission power can be determined based on the second target receiving power and the target transmission power increment.

[0333] The second target received power may be determined by referring to the method in case one, and the target transmission power increment may be determined by referring to the method in case two, which will not be described in detail here.

[0334] After determining the second target receive power and the target transmit power increment, the PUSCH transmit power may be calculated with reference to the aforementioned calculation method for the PUSCH transmit power.

[0335] It should be noted that the PUSCH transmission power in the embodiment of the present disclosure can be the transmission power of a single PUSCH transmission carrying message 3, or it can be the transmission power of any PUSCH transmission carrying message 3 during the repeated transmission of the PUSCH carrying message 3.

[0336] In the embodiment shown in FIG3 , the terminal can accurately calculate the transmit power of the channel during the random access process according to the two sets of power parameters, thereby reducing channel interference on different symbol types.

[0337] Based on the embodiment shown in FIG3 , the following further illustrates the process of determining the transmit power of the present disclosure by taking the transmit power in the random access process as the first PRACH transmit power as an example.

[0338] FIG4 is a second flow chart of a method for determining transmit power according to an embodiment of the present disclosure. As shown in FIG4 , the method is applied to a terminal and includes:

[0339] S401: Receive configuration information, where the configuration information is used to indicate power parameters on SBFD symbols and power parameters on non-SBFD symbols.

[0340] S402: Determine a first PRACH transmit power according to the configuration information.

[0341] It should be noted that the execution process from S401 to S402 can refer to the execution process from S301 to S302, and will not be repeated here.

[0342] S403: Obtain a second PRACH transmit power.

[0343] The second PRACH transmission power is the transmission power of the last PRACH transmission before the current PRACH transmission.

[0344] S404: Determine a target PRACH transmit power according to the first PRACH transmit power and the second PRACH transmit power.

[0345] The target PRACH transmit power may be the transmit power of the current PRACH transmission, that is, the target PRACH transmit power may be the transmit power of the PRACH to be transmitted.

[0346] Next, the target PRACH transmit power may be determined in the following ways.

[0347] 1. If the first PRACH transmit power is greater than or equal to the second PRACH transmit power, the first PRACH transmit power is determined as the target PRACH transmit power.

[0348] 2. If the first PRACH transmit power is less than or equal to the second PRACH transmit power, the second PRACH transmit power is determined as the target PRACH transmit power, or the target PRACH transmit power is determined according to the second PRACH transmit power and the power ramping step corresponding to the first target symbol type.

[0349] The following describes how to determine the target PRACH transmit power according to the second PRACH transmit power and the power ramp-up step corresponding to the first target symbol type in accordance with various situations.

[0350] (1) When the configuration information includes the power ramp step size on SBFD symbols (i.e., the first power ramp step size) and the power ramp step size on non-SBFD symbols (i.e., the second power ramp step size)

[0351] If the first target symbol type is an SBFD symbol, it may be determined that the target PRACH transmit power = the second PRACH transmit power + the first power ramp-up step size.

[0352] If the first target symbol type is a non-SBFD symbol, the target PRACH transmit power may be determined as follows: the second PRACH transmit power + the second power ramp-up step size.

[0353] (2) When the configuration information includes the power ramp step size (i.e., the third power ramp step size) and the power ramp step size offset value on the SBFD symbol

[0354] If the first target symbol type is an SBFD symbol, it may be determined that the target PRACH transmit power = the second PRACH transmit power + the third power ramp-up step size.

[0355] If the first target symbol type is a non-SBFD symbol, the target PRACH transmit power can be determined as follows: the second PRACH transmit power + the third power climbing step + the power climbing step offset value, or the target PRACH transmit power = the second PRACH transmit power + the third power climbing step - the power climbing step offset value.

[0356] (3) When the configuration information includes the power ramp step size (i.e., the third power ramp step size) and the power ramp step size offset value on non-SBFD symbols

[0357] If the first target symbol type is an SBFD symbol, the target PRACH transmit power can be determined as follows: the second PRACH transmit power + the third power climbing step + the power climbing step offset value, or the target PRACH transmit power = the second PRACH transmit power + the third power climbing step - the power climbing step offset value.

[0358] If the first target symbol type is a non-SBFD symbol, the target PRACH transmit power may be determined as follows: the second PRACH transmit power + the third power ramp-up step size.

[0359] In the embodiment shown in FIG4 , the transmit power of the current PRACH transmission is always not less than the transmit power of the previous PRACH transmission. The terminal transmits the PRACH with a larger transmit power, thereby ensuring the PRACH transmission performance and improving the success probability of random access.

[0360] FIG5 is a flowchart of a method for determining transmit power according to an embodiment of the present disclosure. As shown in FIG5 , the method is applied to a network device and includes:

[0361] S501: Determine configuration information, where the configuration information is used to indicate a power parameter on an SBFD symbol and a power parameter on a non-SBFD symbol.

[0362] It should be noted that the relevant description of the configuration information can be found in S301 and will not be repeated here.

[0363] S502: Send configuration information, where the configuration information is used to determine the transmit power during the random access process.

[0364] How to use the configuration information to determine the transmit power during the random access process can be found in the relevant description in S302 and will not be repeated here.

[0365] After sending the configuration information, the network device may also receive the PRACH sent by the terminal or the PUSCH carrying message 3.

[0366] It should be noted that the embodiments of the present disclosure do not limit the configuration method of RO on SBFD symbols and non-SBFD symbols. RO on SBFD symbols and non-SBFD symbols can be configured through one set of RACH resources or two sets of RACH resources.

[0367] Based on the above embodiments, several examples are provided below to illustrate the process of determining the transmit power of the present disclosure.

[0368] Example 1

[0369] S1. A network device determines configuration information, where the configuration information is used to indicate a target received power on SBFD symbols and a target received power on non-SBFD symbols.

[0370] S2. The network device sends configuration information to the terminal.

[0371] In other words, the terminal receives the configuration information sent by the network device.

[0372] S3. The terminal determines the first PRACH transmit power according to the configuration information.

[0373] (1) When the configuration information includes the target received power on the SBFD symbol (ie, the third target received power preambleReceivedTargetPower2) and the target received power on the non-SBFD symbol (ie, the fourth target received power preambleReceivedTargetPower1).

[0374] If the current PRACH is transmitted on an SBFD symbol, preambleReceivedTargetPower2 is used as the first target received power to determine the first PRACH transmit power; if the current PRACH is transmitted on a non-SBFD symbol, preambleReceivedTargetPower1 is used as the first target received power to determine the first PRACH transmit power.

[0375] (2) When the configuration information includes the target received power on the non-SBFD symbol (ie, the fifth target received power preambleReceivedTargetPower) and the target received power offset value preambleReceivedTargetPoweroffset, the target received power on the SBFD symbol can be determined as preambleReceivedTargetPower+preambleReceivedTargetPoweroffset.

[0376] If the current PRACH is transmitted on an SBFD symbol, preambleReceivedTargetPower+preambleReceivedTargetPoweroffset is used as the first target received power to determine the first PRACH transmit power; if the current PRACH is transmitted on a non-SBFD symbol, preambleReceivedTargetPower is used as the first target received power to determine the first PRACH transmit power.

[0377] The first PRACH transmit power may be calculated with reference to the aforementioned calculation method of the PRACH transmit power. When calculating the first PRACH transmit power, the power ramp-up step size adopts a uniquely configured parameter value.

[0378] Example 2

[0379] S1. A network device determines configuration information, where the configuration information is used to indicate a power ramp-up step size on SBFD symbols and a power ramp-up step size on non-SBFD symbols.

[0380] S2. The network device sends configuration information to the terminal.

[0381] In other words, the terminal receives the configuration information sent by the network device.

[0382] S3. The terminal determines the climbing power according to the configuration information.

[0383] The terminal can read two power ramp count parameters, one counting parameter that counts the number of power ramps for PRACH transmission on SBFD symbols, and one counting parameter that counts the number of power ramps for PRACH transmission on non-SBFD symbols. Considering that a power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER is configured on the network side in the related art, this parameter can be reused by non-SBFD symbols, and a new power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER1 is introduced for SBFD symbols, and vice versa. Alternatively, a channel power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER1 is introduced for non-SBFD symbols, and a power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER2 is introduced for SBFD symbols, and vice versa.

[0384] (1) When the configuration information includes the power ramp step size on the SBFD symbol (i.e., the first power ramp step size PREAMBLE_POWER_RAMPING_STEP2) and the power ramp step size on the non-SBFD symbol (i.e., the second power ramp step size PREAMBLE_POWER_RAMPING_STEP1), the terminal may calculate the ramp power of the two symbol types respectively according to the power ramp times and power ramp step sizes of different symbol types, for example: (PREAMBLE_POWER_RAMPING_COUNTER1–1)×PREAMBLE_POWER_RAMPING_STEP1+(PREAMBLE_POWER_RAMPING_COUNTER2–1)×PREAMBLE_POWER_RAMPING_STEP2

[0385] Or, (PREAMBLE_POWER_RAMPING_COUNTER-1)×PREAMBLE_POWER_RAMPING_STEP1+(PREAMBLE_POWER_RAMPING_COUNTER1-1)×PREAMBLE_POWER_RAMPING_STEP2

[0386] (2) When the configuration information includes the power ramp step size on the non-SBFD symbol (i.e., the third power ramp step size PREAMBLE_POWER_RAMPING_STEP) and the power ramp step size offset value PREAMBLE_POWER_RAMPING_STEP_OFFSET, the power ramp step size on the SBFD symbol can be determined to be PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET. The terminal can calculate the ramp power of the two symbol types separately according to the power ramp times and power ramp step sizes of different symbol types, for example:

[0387] (PREAMBLE_POWER_RAMPING_COUNTER1–1)×PREAMBLE_POWER_RAMPING_STEP+(PREAMBLE_POWER_RAMPING_COUNTER2–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0388] or,

[0389] (PREAMBLE_POWER_RAMPING_COUNTER1–1)×PREAMBLE_POWER_RAMPING_STEP1+(PREAMBLE_POWER_RAMPING_COUNTER2–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0390] S4. The terminal determines the first PRACH transmit power according to the ramp-up power.

[0391] The first PRACH transmit power may be calculated with reference to the aforementioned calculation method of the PRACH transmit power. When calculating the first PRACH transmit power, the target receive power adopts a uniquely configured parameter value.

[0392] Example 3

[0393] S1. A network device determines configuration information, where the configuration information is used to indicate a power ramp-up step size on SBFD symbols and a power ramp-up step size on non-SBFD symbols.

[0394] S2. The network device sends configuration information to the terminal.

[0395] In other words, the terminal receives the configuration information sent by the network device.

[0396] S3. The terminal determines the climbing power according to the configuration information.

[0397] The terminal can read two power ramp count parameters, one counting parameter that counts the number of power ramps for PRACH transmission on SBFD symbols, and one counting parameter that counts the number of power ramps for PRACH transmission on non-SBFD symbols. Considering that a power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER is configured on the network side in the related art, this parameter can be reused by non-SBFD symbols, and a new power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER1 is introduced for SBFD symbols, and vice versa. Alternatively, a channel power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER1 is introduced for non-SBFD symbols, and a power ramp count parameter PREAMBLE_POWER_RAMPING_COUNTER2 is introduced for SBFD symbols, and vice versa.

[0398] (1) When the configuration information includes the power ramping step size on the SBFD symbol (i.e., the first power ramping step size PREAMBLE_POWER_RAMPING_STEP2) and the power ramping step size on the non-SBFD symbol (i.e., the second power ramping step size PREAMBLE_POWER_RAMPING_STEP1), the terminal may calculate the ramping power according to the number of power ramps and the power ramping step size corresponding to the symbol type corresponding to the current PRACH transmission. For example, if the current PRACH transmission is on a non-SBFD symbol, the ramping power is:

[0399] (PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP1

[0400] Or, (PREAMBLE_POWER_RAMPING_COUNTER1–1)×PREAMBLE_POWER_RAMPING_STEP1

[0401] The current PRACH transmission is on the SBFD symbol, and the ramp power is:

[0402] (PREAMBLE_POWER_RAMPING_COUNTER1–1)×PREAMBLE_POWER_RAMPING_STEP1

[0403] Or, (PREAMBLE_POWER_RAMPING_COUNTER2–1)×PREAMBLE_POWER_RAMPING_STEP1

[0404] (2) When the configuration information includes the power ramp step size on non-SBFD symbols (i.e., the third power ramp step size PREAMBLE_POWER_RAMPING_STEP) and the power ramp step size offset PREAMBLE_POWER_RAMPING_STEP_OFFSET, the power ramp step size on the SBFD symbol can be determined to be PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET. The terminal calculates the ramp power based on the number of power ramps and the power ramp step size corresponding to the symbol type corresponding to the current PRACH transmission. For example, if the current PRACH transmission is on the SBFD symbol, the ramp power is:

[0405] (PREAMBLE_POWER_RAMPING_COUNTER1–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0406] or,

[0407] (PREAMBLE_POWER_RAMPING_COUNTER2–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0408] The current PRACH transmission is on non-SBFD symbols, and the ramp power is:

[0409] (PREAMBLE_POWER_RAMPING_COUNTER–1)×(PREAMBLE_POWER_RAMPING_STEP)

[0410] or,

[0411] (PREAMBLE_POWER_RAMPING_COUNTER1–1)×(PREAMBLE_POWER_RAMPING_STEP)

[0412] S4. The terminal determines the first PRACH transmit power according to the ramp-up power.

[0413] The first PRACH transmit power may be calculated with reference to the aforementioned calculation method of the PRACH transmit power. When calculating the first PRACH transmit power, the target receive power adopts a uniquely configured parameter value.

[0414] Example 4

[0415] S1. A network device determines configuration information, where the configuration information is used to indicate a power ramp-up step size on SBFD symbols and a power ramp-up step size on non-SBFD symbols.

[0416] S2. The network device sends configuration information to the terminal.

[0417] In other words, the terminal receives the configuration information sent by the network device.

[0418] S3. The terminal determines the climbing power according to the configuration information.

[0419] The terminal can read the power ramp count parameter, which counts the total number of power ramps for SBFD and non-SBFD symbols. Considering that the network side configures a power ramp count parameter, PREAMBLE_POWER_RAMPING_COUNTER, in related technologies, non-SBFD symbols can reuse this count parameter, or introduce a new count parameter, such as PREAMBLE_POWER_RAMPING_COUNTER_TOTAL. This example does not impose any restrictions.

[0420] (1) When the configuration information includes the power ramping step size on the SBFD symbol (i.e., the first power ramping step size PREAMBLE_POWER_RAMPING_STEP2) and the power ramping step size on the non-SBFD symbol (i.e., the second power ramping step size PREAMBLE_POWER_RAMPING_STEP1), the terminal may calculate the ramping power according to the symbol type corresponding to the current PRACH transmission or the power ramping step size corresponding to the symbol type corresponding to the first PRACH transmission. For example, if the current PRACH transmission or the first PRACH transmission is on a non-SBFD symbol, the ramping power is:

[0421] (PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_STEP1

[0422] Or, (PREAMBLE_POWER_RAMPING_COUNTER_TOTAL–1)×PREAMBLE_POWER_RAMPING_STEP1

[0423] (2) When the configuration information includes the power ramp step size on non-SBFD symbols (i.e., the third power ramp step size PREAMBLE_POWER_RAMPING_STEP) and the power ramp step size offset PREAMBLE_POWER_RAMPING_STEP_OFFSET, the power ramp step size on the SBFD symbol can be determined to be PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET. The terminal calculates the ramp power according to the symbol type corresponding to the current PRACH transmission or the power ramp step size corresponding to the symbol type corresponding to the first PRACH transmission. For example, if the current PRACH transmission or the first PRACH transmission is on the SBFD symbol, the ramp power is:

[0424] (PREAMBLE_POWER_RAMPING_COUNTER–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0425] or,

[0426] (PREAMBLE_POWER_RAMPING_COUNTER_TOTAL–1)×(PREAMBLE_POWER_RAMPING_STEP+PREAMBLE_POWER_RAMPING_STEP_OFFSET)

[0427] S4. The terminal determines the first PRACH transmit power according to the ramp-up power.

[0428] The first PRACH transmit power may be calculated with reference to the aforementioned calculation method of the PRACH transmit power. When calculating the first PRACH transmit power, the target receive power adopts a uniquely configured parameter value.

[0429] Example 5:

[0430] S1. The network device determines configuration information, where the configuration information is used to indicate a target received power and a power ramp step size on SBFD symbols, and a target received power and a power ramp step size on non-SBFD symbols.

[0431] S2. The network device sends configuration information to the terminal.

[0432] In other words, the terminal receives the configuration information sent by the network device.

[0433] S3. The terminal determines the first PRACH transmit power according to the configuration information.

[0434] The terminal may determine the first target received power with reference to Example 1, may determine the ramp-up power with reference to Example 2, Example 3 or Example 4, and then determine the first PRACH transmit power based on the first target received power and the ramp-up power.

[0435] Example 6

[0436] S1. The terminal determines a first PRACH transmit power based on any one of Examples 1 to 4, denoted as P.

[0437] S2. The terminal obtains the transmit power of the last PRACH transmission before the current PRACH transmission (the second PRACH transmit power), which is recorded as P'.

[0438] P' can be stored through newly introduced parameters or obtained through other methods, which is not limited in this example.

[0439] S3. The terminal determines the target PRACH transmit power according to P and P'.

[0440] If P is greater than or equal to P', the terminal may determine P as the target PRACH transmit power for transmitting the current PRACH.

[0441] If P is less than or equal to P', the terminal may determine P' as the target PRACH transmit power to transmit the current PRACH.

[0442] If P is less than or equal to P', the target PRACH transmit power is determined to be equal to P' plus the power ramping step size corresponding to the symbol type in which the current PRACH transmission is located. Assuming that the terminal transmits the current PRACH in an SBFD symbol, the target PRACH transmit power is P' + PREMBLE_POWER_RAMPING_STEP2, or P' + (PREAMBLE_POWER_RAMPING_STEP + PREMBLE_POWER_RAMPING_STEP_OFFSET).

[0443] Since the terminal currently calculates the transmit power separately for the PRACH transmitted in each RO, any one of the methods in Example 1 to Example 5 can be used to calculate the transmit power of a single PRACH transmission, or to independently calculate the transmit power of each PRACH transmission in multiple PRACH transmissions.

[0444] In addition, in Examples 1 to 6, when the terminal determines the symbol type of the current PRACH transmission, it only considers whether the time domain resources of the current PRACH transmission are on SBFD symbols or non-SBFD symbols. The present disclosure does not limit whether the RO resources are configured through RACHConfig-Common or Additional-RACHConfig.

[0445] Example 7

[0446] S1. A network device determines configuration information, where the configuration information is used to indicate a target received power on SBFD symbols and a target received power on non-SBFD symbols.

[0447] S2. The network device sends configuration information to the terminal.

[0448] In other words, the terminal receives the configuration information sent by the network device.

[0449] S3. The terminal determines the PUSCH transmit power according to the configuration information.

[0450] (1) When the configuration information includes the target received power on the SBFD symbol (ie, the third target received power preambleReceivedTargetPower2) and the target received power on the non-SBFD symbol (ie, the fourth target received power preambleReceivedTargetPower1).

[0451] When calculating the PUSCH transmit power, the terminal may determine the second target receive power based on the symbol type in which the PUSCH currently carrying message 3 is transmitted. If the PUSCH currently carrying message 3 is transmitted on an SBFD symbol, preambleReceivedTargetPower2 is used as the second target receive power to determine the PUSCH transmit power. If the PUSCH currently carrying message 3 is transmitted on a non-SBFD symbol, preambleReceivedTargetPower1 is used as the second target receive power to determine the PUSCH transmit power.

[0452] When calculating the PUSCH transmit power, the terminal can determine the second target receive power based on the symbol type of the current RACH attempt PRACH transmission. If the PRACH of the current RACH attempt is transmitted on a non-SBFD symbol, preambleReceivedTargetPower1 is used as the second target receive power to determine the PUSCH transmit power. If the PRACH of the current RACH attempt is transmitted on an SBFD symbol, preambleReceivedTargetPower2 is used as the second target receive power to determine the PUSCH transmit power.

[0453] (2) When the configuration information includes the target received power on the non-SBFD symbol (ie, the fifth target received power preambleReceivedTargetPower) and the target received power offset value preambleReceivedTargetPoweroffset, the target received power on the SBFD symbol can be determined as preambleReceivedTargetPower+preambleReceivedTargetPoweroffset.

[0454] When calculating the PUSCH transmit power, the terminal may determine the second target receive power based on the symbol type on which the PUSCH currently carrying message 3 is transmitted. If the PUSCH currently carrying message 3 is transmitted on an SBFD symbol, preambleReceivedTargetPower+preambleReceivedTargetPoweroffset is used as the second target receive power to determine the PUSCH transmit power. If the PUSCH currently carrying message 3 is transmitted on a non-SBFD symbol, preambleReceivedTargetPower is used as the second target receive power to determine the PUSCH transmit power.

[0455] When calculating the PUSCH transmit power, the terminal may determine the second target receive power based on the symbol type of the current RACH attempt PRACH transmission. If the PRACH of the current RACH attempt is transmitted on a non-SBFD symbol, the preambleReceivedTargetPower is used as the second target receive power to determine the PUSCH transmit power. If the PRACH of the current RACH attempt is transmitted on an SBFD symbol, the preambleReceivedTargetPower + preambleReceivedTargetPoweroffset is used as the second target receive power to determine the PUSCH transmit power.

[0456] The PUSCH transmit power may be calculated by referring to the aforementioned calculation method of the PUSCH transmit power. When calculating the PUSCH transmit power, the transmit power increment adopts a uniquely configured parameter value.

[0457] Example 8

[0458] S1. A network device determines configuration information, where the configuration information is used to indicate a transmission power increment on an SBFD symbol and a transmission power increment on a non-SBFD symbol.

[0459] S2. The network device sends configuration information to the terminal.

[0460] In other words, the terminal receives the configuration information sent by the network device.

[0461] S3. The terminal determines the PUSCH transmit power according to the configuration information.

[0462] (1) When the configuration information includes the transmission power increment on the SBFD symbol (ie, the first transmission power increment msg3-DeltaPreamble2 or deltaPreamble2) and the target reception power on the non-SBFD symbol (ie, the second transmission power increment msg3-DeltaPreamble1 or deltaPreamble1).

[0463] When determining the PUSCH transmit power, the terminal may determine the target transmit power increment based on the symbol type in which the PUSCH currently carrying message 3 is transmitted. If the PUSCH currently carrying message 3 is transmitted on a non-SBFD symbol, msg3-DeltaPreamble1 or deltaPreamble1 is used as the target transmit power increment to determine the PUSCH transmit power; if the PUSCH currently carrying message 3 is transmitted on an SBFD symbol, msg3-DeltaPreamble2 or deltaPreamble2 is used as the target transmit power increment to determine the PUSCH transmit power.

[0464] (2) When the configuration information includes the transmission power increment on the non-SBFD symbol (i.e., the third transmission power increment msg3-DeltaPreamble or deltaPreamble) and the transmission power increment offset value msg3-DeltaPreambleoffset or deltaPreambleoffset, the transmission power increment on the SBFD symbol can be determined to be msg3-DeltaPreamble+msg3-DeltaPreambleoffset or DeltaPreamble+DeltaPreambleoffset.

[0465] When determining the PUSCH transmit power, the terminal may determine the target transmit power increment based on the symbol type in which the PUSCH currently carrying message 3 is transmitted. If the PUSCH currently carrying message 3 is transmitted on a non-SBFD symbol, msg3-DeltaPreamble or deltaPreamble is used as the target transmit power increment to determine the PUSCH transmit power; if the PUSCH currently carrying message 3 is transmitted on an SBFD symbol, msg3-DeltaPreamble+msg3-DeltaPreambleoffset or DeltaPreamble+DeltaPreambleoffset is used as the target transmit power increment to determine the PUSCH transmit power.

[0466] The PUSCH transmit power may be calculated by referring to the aforementioned calculation method of the PUSCH transmit power. When calculating the PUSCH transmit power, the target transmission power adopts a uniquely configured parameter value.

[0467] Example 9

[0468] S1. A network device determines configuration information, where the configuration information is used to indicate a target receive power and a transmit power increment on SBFD symbols, and a target receive power and a transmit power increment on non-SBFD symbols.

[0469] S2. The network device sends configuration information to the terminal.

[0470] In other words, the terminal receives the configuration information sent by the network device.

[0471] S3. The terminal determines the PUSCH transmit power according to the configuration information.

[0472] The terminal may determine the second target received power with reference to Example 6, may determine the target transmission power increment with reference to Example 7, and then determine the PUSCH transmission power based on the second target received power and the target transmission power increment.

[0473] Since the terminal currently calculates the transmit power separately for each PUSCH carrying message 3, any one of the methods in Examples 7 to 8 can be used to calculate the transmit power of a single PUSCH transmission carrying message 3, or can be used to independently calculate the transmit power of each PUSCH transmission carrying message 3 in repeated transmissions of the PUSCH carrying message 3.
