[002] In the 3G Generation Partnership Project (3GPP) Edition 15 (R15), a single random access channel (RACH) attempt transmits the physical random access channel (PRACH) transmission only once. For PRACH retransmission, a power ramp mechanism is introduced, where each retransmission increases the PRACH transmission power by one step, specifying the conditions under which a user equipment (UE) performs the power ramp.

[003] In R18 CE WI, the introduction of a multiple PRACH transmission mechanism for a single RACH attempt is considered. Techniques such as uncorrelated fusion can increase the probability of successful detection and improve PRACH coverage. However, in scenarios where multiple PRACH transmissions are introduced, it is still unclear how the UE supports the power ramp mechanism in the RACH attempt. SUMMARY

[0024] The modalities of the description are described in detail below, examples of which are shown in the attached drawings, in which the same Petition 870250103869, dated 11 / 13 / 2025, p. 9 / 90 / 37 reference numbers or similar numbers represent the same elements or similar elements or elements with equal or similar functions. The embodiments described below with reference to the attached drawings are exemplary and are intended to explain the description, which should not be interpreted as limitations to the description.

[0025] To enhance PRACH coverage, R18 CE WI is considering introducing a mechanism for multiple PRACH transmissions for a single RACH attempt. This approach increases the probability of successful detection through techniques such as uncorrelated fusion. In contrast, R15 specifies that only one PRACH is transmitted per RACH attempt.

[0026] Regarding a power allocation priority for a plurality of uplink (UL) channels in a carrier aggregation (CA) scenario, R15 reached the following conclusions.

[0027] In a case where a component carrier (CC) / UL configured for UE is transmitted simultaneously on a shared physical uplink (PUSCH) / physical uplink control channel (PUCCH) for the same transmission duration, and different CCs and ULs from one or two PUCCH groups share the same numerology and exhibit overlapping transmission, when UE power is limited due to simultaneous transmissions in multiple service cells, the power allocation priority is: PRACH transmission in a primary cell (PCell) > positive acknowledgment / negative acknowledgment (ACK / NACK) transmission and / or scheduling request (SR) transmission in a PUCCH or a PUSCH > uplink control information (UCI) transmission in a PUCCH or a PUSCH > UCI on / off transmission in a PUSCH > probe reference signal (SRS) / PRACH transmission in a secondary cell (SCell).

[0028] 1. At the same priority level, PCell has a priority Petition 870250103869, dated 11 / 13 / 2025, p. 10 / 90 / 37 greater than SCell.

[0029] 2. To prevent transmission power from exceeding a maximum power (Pcmax), power reduction or transmission cancellation is applied first to the lowest priority, then to the second lowest priority, and so on until the aggregate power is less than or equal to the maximum power (Pcmax). Specifically, power reduction or transmission cancellation is implemented by the UE.

[0030] Therefore, if the sum of the UL transmission powers of all CCs within a slot exceeds the UE's maximum transmission power, the UE will carry out power allocation according to the priority above, to ensure channel transmissions with higher priorities. For channel transmissions with lower priorities, the decision on whether to carry out channel transmissions with reduced transmission power or to cancel these channel transmissions is determined by the UE.

[0031] In R15, the power ramp mechanism is introduced for PRACH retransmissions. With each additional retransmission, the PRACH transmit power will increase by one step. If any of the following three conditions occur, a power ramp counter will not increase its count number by 1: 1. An index of the Physical Broadcast Channel and Synchronization Block (PBCH) (SSB) used for RACH (RO) occasion selection has been changed; 2. A space filter for a UL transmission has been changed; and 3. The transmission power for the current PRACH transmission has been reduced or the current transmission has been canceled due to power allocation.

[0032] Therefore, according to the power allocation priority of the channels in R15, it can be determined that, for a PRACH transmission with the lowest channel priority, the transmission power may be reduced or the transmission may be cancelled. For such a situation, R15 specifies that the Petition 870250103869, dated 11 / 13 / 2025, page 11 / 90 / 37, the UE power ramp counter will pause its increment at 1. That is, if the transmission power for the current transmission is reduced or the current transmission is canceled, the power ramp will not be performed for the next PRACH retransmission.

[0033] However, the R18 CE WI introduced the power ramp mechanism for a plurality of PRACH transmissions. When the transmission power of one or more PRACH transmissions among the plurality of PRACH transmissions is reduced and / or one or more PRACH transmissions are cancelled, it is unclear how the UE performs the power ramp in the subsequent PRACH attempt.

[0034] Therefore, the description provides a method for determining power ramp, a power ramp determination apparatus and a communication device, and proposes a power ramp mechanism for a plurality of PRACH transmissions, which clarifies how the UE performs the power ramp when power allocation causes a reduction in transmission power of one or more PRACH transmissions and / or a cancellation of one or more PRACH transmissions among the plurality of PRACH transmissions.

[0035] It is understood that the solution provided by the description can be applied to Fifth Generation (5G) and its future communication technologies, such as advanced 5G and Sixth Generation (6G), which are not limited in the description.

[0036] The solution for determining the power ramp provided by the description will be presented in detail in conjunction with the attached drawings.

[0037] Figure 1 is a schematic flowchart of a method for determining power ramp according to an embodiment of the description. As illustrated in Figure 1, the method is performed by a UE. In the embodiment of the description, the UE includes, but is not limited to, a UE. Petition 870250103869, dated 11 / 13 / 2025, page 12 / 90 / 37 intelligent, a cell phone, a wireless device, an appliance, a mobile unit, a vehicle and a vehicle-mounted device, which is not limited in the description.

[0038] The method includes the following steps.

[0039] In step S101, for a plurality of PRACH transmissions within a RACH attempt, it is determined whether the power ramp should be performed based on network device configuration information or based on a protocol.

[0040] In the embodiment of the description, the network device includes, but is not limited to, a switch, a router, a bridge, a hub, a connection port, a network interface card (NIC), a wireless access point (WAP), and a base station, which is not limited in the description.

[0041] It is understandable that in a scenario where R18 CE WI proposed performing a plurality of PRACH transmissions within a RACH attempt, in the plurality of PRACH transmissions above, the PRACH retransmission may be initiated because the UE does not receive a Random Access Response (RAP), or the UE does not receive its corresponding RAP ID, or the UE fails contention resolution. If the power ramp mechanism is introduced at this point, the UE's behavior needs to be clarified. That is, it is necessary to determine under what conditions the UE performs or does not perform the power ramp.

[0042] In the description mode, the UE can determine whether to perform the power ramp based on configuration information or indication information from the network device. For example, when the UE receives configuration information or indication information from the network device that indicates to the UE to perform the power ramp on the PRACH relay, the UE performs the power ramp, that is, the power ramp counter count will be increased by one, and the PRACH transmission power will be increased by one step. The UE Petition 870250103869, dated 11 / 13 / 2025, page 13 / 90 / 37, can also determine whether to perform the power ramp based on the protocol. For example, if the protocol specifies that during 8 PRACH transmissions, even if the transmission power is reduced or the transmission is canceled in 3 PRACH transmissions due to power allocation, the power ramp will still be performed, that is, the power ramp counter count will still be increased by one.

[0043] It should be noted that the solution in the description can be applied to contention-free random access (CFRA) or contention-based random access (CBRA), which is not limited in the description.

[0044] In conclusion, according to the power ramp determination method described, for multiple PRACH transmissions within a RACH attempt, the UE determines whether to perform the power ramp based on network device configuration information or based on the protocol. The description proposes a power ramp mechanism for multiple PRACH transmissions, which clarifies the UE's behavior while ensuring PRACH coverage.

[0045] Figure 2 is a schematic flowchart of a method for determining power ramp according to an embodiment of the description. The method is performed by a UE. Based on the embodiment of Figure 1, as illustrated in Figure 2, the method includes the following steps.

[0046] In step S201, configuration information sent by a network device is received.

[0047] The configuration information carries information that indicates whether the UE performs the power ramp or not.

[0048] Configuration information can be carried in a radio resource control (RRC) signal or in a downlink control information (DCI) field. For example, it can be configured directly in the RRC signal or it can be Petition 870250103869, dated 11 / 13 / 2025, page 14 / 90 / 37, referred to in the DCI field as some dynamic indications.

[0049] Configuration information can be implicit or explicit. If the configuration information is explicit, for example, when the indication information in the configuration information sent by the network device is 1, this indicates that the UE should perform the power ramp, and if the indication information is 0, this indicates that the UE should not perform the power ramp. If the configuration information is implicit, for example, if the configuration information is not received, or if the configuration information does not contain information indicating to the UE to perform the power ramp, it is determined that the power ramp will not be performed.

[0050] In step S202, for a plurality of PRACH transmissions within a RACH attempt, it is determined whether the power ramp should be performed based on network device configuration information or based on a protocol.

[0051] In some embodiments of the description, determining whether to perform a power ramp based on network device configuration information includes: in response to receiving configuration information or in response to receiving configuration information that indicates to the UE that it should perform a power ramp, determining that the power ramp should be performed; or in response to not receiving configuration information or in response to receiving configuration information that indicates to the UE that it should not perform a power ramp, determining that the power ramp should not be performed.

[0052] The configuration information sent to the UE by the network device may directly contain dedicated configuration information indicating whether the UE performs power ramping or not, or it may be other configuration information sent by the network device, which Petition 870250103869, dated 11 / 13 / 2025, page 15 / 90 / 37, can be reused to implicitly indicate whether the UE performs the power ramp or not. That is, when the PRACH retransmission is initiated, if the UE receives network device configuration information or the received configuration information contains information indicating that the UE should perform the power ramp, the UE determines whether to perform the power ramp. If the UE does not receive network device configuration information or the received configuration information does not contain information indicating to the UE that it should perform the power ramp, the UE will determine not to perform the power ramp.

[0053] It is understood that in R15, there is only one PRACH transmission within a RACH attempt. If the transmission power of the PRACH transmission is reduced or the PRACH transmission is canceled due to power allocation, it is determined that the power ramp will not be performed when initiating the PRACH retransmission.

[0054] In scenarios where the R18 CE WI considers the introduction of a plurality of PRACH transmissions within a RACH attempt, power allocation may cause reduced transmission power of one or more PRACH transmissions and / or cancellation of one or more PRACH transmissions among the plurality of PRACH transmissions, the solution in the mode may be adopted. Based on configuration information or indication from the network device, it is possible to determine whether the power ramp should be performed when a given PRACH transmission is canceled or its transmission power is reduced.

[0055] In one embodiment of the description, the configuration information sent by the network device may also carry a threshold P of a numerical count of PRACH transmissions. It should be understood that in some optional implementations, the threshold P may be carried by other messages, which is not limited to the description.

[0056] The threshold P of the numerical count of PRACH transmissions Petition 870250103869, dated 11 / 13 / 2025, page 16 / 90 / 37 includes: a Q threshold for a numerical count of transmission power reduction and / or a K threshold for a numerical count of PRACH transmission cancellation. The UE can make a decision on whether to perform the power ramp on the next RACH attempt based on the Q and / or K configured by the network device. For example, when a PRACH transmission cancellation numerical count exceeds K, the power ramp will not be performed for the next RACH attempt, i.e., the power ramp counter pauses its increment at 1.

[0057] In some embodiments of the description, determining whether to perform the power ramp based on the protocol includes: in the event of a first event agreed upon in the protocol, determining whether to perform the power ramp.

[0058] The first event is: for PRACH transmission plurality, less than or equal to am PRACH transmissions are reduced in transmission power or cancelled due to a power allocation, om is less than a numerical count n of transmissions for PRACH transmission plurality determined by the UE, eom is agreed in the protocol.

[0059] For example, if there are four PRACH transmissions in a PRACH attempt, the numerical count n of transmissions for the four PRACH transmissions will be 8. For the numerical count n of transmissions for the four PRACH transmissions, less than or equal to am, the PRACH transmissions are reduced in transmission power or canceled due to a power allocation (including 1, 2, 3, ... m PRACH transmissions), om is less than on, that is, 8. That is, when 1 <m<8, ocorre o primeiro evento acordado no protocolo, e é determinado realizar a rampa de potência durante a retransmissão do PRACH, ou seja, o número de contagem do contador de rampa de potência é incrementado em 1.

[0060] In an optional embodiment of the description, the method includes Petition 870250103869, dated 11 / 13 / 2025, p. 17 / 90 / 37 still: receive a candidate numerical count of transmissions for the plurality of PRACH transmissions sent by the network device; and determine on based on the candidate numerical count of transmissions.

[0061] In detail, a dataset configured by the network device for the UE includes a plurality of candidate numerical counts of transmissions. By comparing the received power of the measured reference signal with various thresholds, the UE can determine the on. For example, the data includes 2, 4, and 8, and the received power of the measured reference signal is within a third threshold interval, so it is determined that on is 8.

[0062] It should be noted that, in some implementations, the UE may still determine whether the first event agreed upon in the protocol occurs after determining the execution of the power ramp based on the network device configuration information. If the first event agreed upon in the protocol occurs, the UE determines whether to execute the power ramp. Or, if the UE does not receive the configuration information sent by the network device, it needs to determine whether the first event agreed upon in the protocol occurs and, if the first event agreed upon in the protocol occurs, the UE determines whether to execute the power ramp.

[0063] In some embodiments of the description, determining whether to perform the power ramp based on the protocol includes: in the event of a second event agreed upon in the protocol, determining whether to perform the power ramp.

[0064] The second event is: for the plurality of PRACH transmissions, at least one PRACH transmission is reduced in transmission power or canceled due to power allocation.

[0065] For example, if the numerical count of transmissions for the plurality of transmissions PRACH is n, and the numerical count of transmissions whose transmission power was reduced or canceled due to Petition 870250103869, dated 11 / 13 / 2025, page 18 / 90 / 37 power allocation for m, then when 1 <m<n, é determinado que a rampa de potência não será realizada, o que significa que o contador de rampa de potência pausará o incremento em 1.

[0066] It should be noted that, in some implementations, the UE may further determine whether the second event agreed upon by the protocol occurs after determining whether the power ramp will not be performed based on the network device's configuration information, and determine whether the power ramp will not be performed if the second event agreed upon by the protocol occurs. Or the UE may determine whether the second event agreed upon by the protocol occurs if it does not receive the configuration information sent by the network device, and determine whether the power ramp will not be performed if the second event agreed upon by the protocol occurs.

[0067] In conclusion, according to the power ramp determination method described, for the plurality of PRACH transmissions within a RACH attempt, when the transmission power of one or more PRACH transmissions is reduced and / or one or more PRACH transmissions are cancelled, it becomes clear how the UE performs the power ramp in subsequent RACH attempts.

[0068] Figure 3 is a schematic flowchart of a method for determining power ramp according to an embodiment of the description. The method is performed by a UE. Based on the embodiment in Figure 1 and / or the embodiment in Figure 2, as illustrated in Figure 3, the method includes the following steps.

[0069] In step S301 for a plurality of PRACH transmissions within a RACH attempt, a threshold P of a numerical count of PRACH transmissions is determined based on configuration information from a network device or based on a protocol.

[0070] In the description modality, the UE determines the P threshold for the numerical count of PRACH transmissions based on the information from Petition 870250103869, dated 11 / 13 / 2025, page 19 / 90 / 37 network device configuration. OP can be sent by the network device independently, or P can be carried in the configuration information sent by the network device and sent along with the information indicating whether the UE performs power ramping or not. The UE can also determine the P threshold of the PRACH transmission numerical count based on the protocol, which is not limited by the description.

[0071] OP can be a fixed value, or P=N / 2, P=N-offset, offset=1 / 2 / N / N-1, which is not limited in the description.

[0072] In step S302, a numerical count p of PRACH transmissions is determined in the event of a third event for the plurality of PRACH transmissions.

[0073] The third event is a transmission power of a PRACH transmission that is reduced or a PRACH transmission is cancelled due to a power allocation.

[0074] In step S303, it is determined whether to perform the power ramp based on a relationship between P and p.

[0075] That is, in a case where the transmission power of a PRACH transmission is reduced or a PRACH transmission is cancelled due to a power allocation, the UE can determine whether to perform the power ramp by comparing the threshold P of the numerical count of PRACH transmissions with the numerical count p of PRACH transmissions in a case where the transmission power of a PRACH transmission is reduced or a PRACH transmission is cancelled due to a power allocation.

[0076] In some embodiments, an optional implementation of step S303 includes: in one case p<P, determinar realizar a rampa de potência; ou em um caso p> P, determine whether or not to perform the power ramp.

[0077] That is, when P is less than or equal to P, PRACH transmissions are reduced in transmission power or cancelled due to a Petition 870250103869, dated 11 / 13 / 2025, page 20 / 90 / 37 power allocation, it is determined that the power ramp will be performed, and the power ramp counter count is increased by 1. If there is more than P, PRACH transmissions are reduced in transmission power or canceled due to a power allocation, it is determined that the power ramp will not be performed, and the power ramp counter pauses its increment at 1.

[0078] In some embodiments, P includes a threshold Q of a numerical count of reduced transmission power and a threshold K of a numerical count of PRACH transmission cancellation, and P includes a numerical count q of PRACH transmissions with reduced transmission powers due to power allocation for PRACH plurality transmissions and a numerical count k of PRACH transmissions cancelled due to power allocation for PRACH plurality transmissions, an optional implementation of step S303 includes: in a case k <K e q<Q, determinar a realização da rampa de potência; ou em um caso k> K or q>Q, determine the non-realization of the power ramp. An optional implementation of step S303 includes: in a case k <K e q<Q, determinar a realização da rampa de potência; ou em um caso k> If K or q > Q, determine whether the power ramp will not occur.

[0079] In other words, the optional implementation separates two scenarios of PRACH transmission power reduction and PRACH transmission cancellation, and determines whether to perform the power ramp based on two thresholds: Q and K. In a case q > <Q e k<K, é determinado realizar a rampa de potência, e o número de contagem do contador de rampa de potência é aumentado em 1. Em um caso k>K or q > Q, it is determined that the power ramp should not be performed, and the power ramp counter pauses its increment at 1.< / q>

[0080] In some embodiments, when P includes the Q threshold of a numerical count of transmission power reduction and the K threshold ​Petition 870250103869, dated 11 / 13 / 2025, page 21 / 90 / 37 of a numerical count of PRACH transmission cancellation, eop includes the numerical count q of PRACH transmissions with reduced transmission power due to power allocation for the plurality of PRACH transmissions and the numerical count k of PRACH transmissions canceled due to power allocation for the plurality of PRACH transmissions, another optional implementation of step S303 includes: in a case p <P, q<Q e k<K, determinar a realização da rampa de potência; ou em um caso em que qualquer um dentre p> If P, q>Q and k>K are satisfied, determine if the power ramp does not occur.

[0081] In other words, the mode determines whether to perform the power ramp based on three thresholds, including P, Q, and K. In a case where q <Q e k<K e p=q+k<P, é determinado realizar a rampa de potência, e o número de contagem do contador de rampa de potência é aumentado em 1. Caso contrário, quando qualquer um dentre p>> P, q > Q, and k > K is satisfied, it will be determined not to perform the power ramp, and the power ramp counter will pause its increment at 1.< / q>

[0082] It should be noted that the modality described can be implemented independently or in combination with the modality shown in Figure 2. For example, after determining whether to perform the power ramp based on the network device configuration information, the UE still needs to determine whether to perform the power ramp based on the relationship between opeo P, which is not limited in the description. ​

[0083] In conclusion, according to the power ramp determination method described, it is clear that the UE determines P based on network device configuration information or based on the protocol and then determines op, in order to determine whether to perform the power ramp based on the relationship between opeo P.

[0084] Figure 4 is a schematic flowchart of a method for determining a power ramp according to one embodiment of Petition 870250103869, dated 11 / 13 / 2025, page 22 / 90 / 37 description. The method is performed by a network device. As illustrated in Figure 4, the method includes the following steps. In the embodiment of the description, the network device includes, but is not limited to, a switch, a router, a bridge, a hub, a connection port, a NIC, a WAP, and a base station, which is not limited in the description.

[0085] In step S401, configuration information is sent to a UE.

[0086] The configuration information carries information that indicates whether the UE performs the power ramp or not.

[0087] In the modality of the description, the UE includes, but is not limited to, a smart UE, a mobile phone, a wireless device, an appliance, a mobile unit, a vehicle and a vehicle-mounted device, which is not limited in the description.

[0088] In the description mode, configuration information can be carried in an RRC signal or in a DCI field. For example, it can be configured directly in the RRC signal or it can be carried in the DCI field as some dynamic indications.

[0089] In detail, corresponding to the mode in figure 2, for a plurality of PRACH transmissions within a RACH attempt, the network device sends configuration information to the UE, so that the UE can determine whether to execute the power ramp based on the network device's configuration information.

[0090] Configuration information can be implicit or explicit. If the configuration information is explicit, for example, when the indication information in the configuration information sent by the network device is 1, this indicates that the UE should perform the power ramp, and if the indication information is 0, this indicates that the UE should not perform the power ramp. If the configuration information is implicit, for example, if the information of Petition 870250103869, dated 11 / 13 / 2025, page 23 / 90 / 37 configuration is not received, or if the configuration information contains information that indicates to the UE not to perform the power ramp, it is determined that the power ramp will not be performed.

[0091] In one embodiment of the description, the configuration information sent by the network device may carry a threshold P of a numerical count of PRACH transmissions, or P is sent to the UE by the network device independently. Correspondingly, in the embodiment in Figure 3, the UE can determine P by receiving the configuration information sent by the network device.

[0092] In some modes, the method also includes: sending a candidate numerical count of transmissions to the PRACH transmission plurality.

[0093] The candidate numerical count of transmissions is used to assist the EU in determining the n.

[0094] In detail, corresponding to the mode in figure 2, the network device sends a plurality of candidate numerical counts of transmissions for the PRACH plurality of transmissions to the UE, the UE receives the plurality of candidate numerical counts of transmissions for the PRACH plurality of transmissions sent by the network device and determines on based on the plurality of candidate numerical counts of transmissions.

[0095] In conclusion, according to the power ramp determination method described, the network device sends configuration information to the UE, in which the configuration information carries information indicating whether the UE performs the power ramp or not, so that the UE can determine whether to perform the power ramp based on the configuration information, which proposes a power ramp mechanism for a plurality of PRACH transmissions.

[00101] In one embodiment of the description, determining whether to perform a power ramp based on the protocol includes: in the event of a first event agreed upon in the protocol, determining whether to perform a power ramp; where the first event is: for the plurality of PRACH transmissions, less than or equal to am PRACH transmissions are reduced in transmission power or canceled due to an allocation.
