[0026] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0027] To enhance PRACH coverage, R18 CE WI considers introducing multiple PRACH transmissions for one RACH attempt, thereby increasing the probability of successful detection through non-correlated combining. In R15, only one PRACH is sent for one RACH attempt.

[0028] Regarding the power allocation priority of multiple UL channels in the carrier aggregation (CA) scenario, Release 15 has the following conclusions:

[0029] In the case where the component carrier (CC) / uplink configured for the UE has the same start time, the same PUSCH (Physical Uplink Shared Channel) / PUCCH (Physical Uplink Control Channel) transmission duration, the same physical parameter set (mumerology) between different CCs / uplinks with one or two PUCCH groups, and overlapping transmission, when the UE is power-limited due to simultaneous transmissions from multiple serving cells, the power allocation priority is: PRACH transmission of PCell (Primary Cell) > ACK / NACK transmission and / or SR transmission on PUCCH / PUSCH > other UCIs transmission on PUCCH / PUSCH > UCI transmission on / not on PUSCH > SRS / PRACH transmission of SCell (Secondary Cell).

[0030] 1. In the same priority level, PCell has a higher priority than SCell.

[0031] 2. In case the transmission power exceeds Pcmax, power reduction or transmission cancellation is applied first to the lowest priority until the aggregate power is within the Pcmax range. The exact reduction or cancellation is implemented by the terminal.

[0032] It can be seen from this that if the sum of the uplink transmit power of all CCs in a time slot exceeds the maximum transmit power of the terminal, power allocation is performed according to the above priority, first ensuring the transmission of higher-priority channels. For low-priority channels, whether to reduce power or cancel transmission depends on the terminal implementation.

[0033] R15 introduces a power boost mechanism for PRACH retransmissions. With each additional retransmission, the PRACH channel will increase its transmit power by one step. If any of the following three conditions occurs, the power boost counter will pause and increment by 1:

[0034] 1. The SSB index used for RO selection changes.

[0035] 2. The spatial filter for uplink transmission changes.

[0036] 3. Due to power allocation, the PRACH transmission power is reduced or the transmission is canceled.

[0037] Therefore, according to the power allocation channel priority in R15, it can be determined that for the PRACH transmission with the lowest channel priority, power reduction or transmission cancellation may occur. R15 clearly stipulates that the power increase counter of the terminal in this scenario is suspended and added by 1, that is, the current transmission power is reduced or the transmission is canceled, and the power will no longer be increased for the next PRACH retransmission.

[0038] However, for the scenario where multiple PRACH transmissions are introduced in R18 CE WI, when power allocation occurs and causes the power of one or several PRACH transmissions among multiple PRACH transmissions to be reduced, and / or one or several PRACH transmissions to be cancelled, it is not yet clear how the terminal performs power boosting in subsequent RACH attempts.

[0039] To this end, the present disclosure proposes a power boost determination method, apparatus, and communication equipment, and proposes a power boost mechanism under multiple PRACH transmissions, clarifying how the terminal performs power boost when power allocation occurs, resulting in a reduction in the power of one or several PRACH transmissions among multiple PRACH transmissions, and / or the cancellation of one or several PRACH transmissions.

[0040] It can be understood that the solution provided in the present disclosure can be used for the fifth generation mobile communication technology (Fifth Generation, 5G) and its subsequent communication technologies, such as the fifth generation mobile communication technology evolution (5G-advanced), the sixth generation mobile communication technology (Sixth Generation, 6G), etc., and is not limited in the present disclosure.

[0041] The power boost determination solution provided in this application is described in detail below with reference to the accompanying drawings.

[0042] Figure 1 illustrates a flow chart of a method for determining a power boost according to an embodiment of the present disclosure. As shown in Figure 1 , the method is performed by a user equipment (UE). In the embodiments of the present disclosure, user equipment (UE) includes, but is not limited to, intelligent terminal devices, cellular phones, wireless devices, handsets, mobile units, vehicles, and in-vehicle equipment, and is not limited in this disclosure.

[0043] The method may include the following steps.

[0044] S101 : For multiple physical random access channel (PRACH) transmissions in one random access channel (RACH) attempt, determine whether to perform power boosting based on configuration information of a network device or based on a protocol agreement.

[0045] In the embodiments of the present disclosure, network devices include but are not limited to switches, routers, bridges, hubs, gateways, network interface cards (NICs), wireless access points (WAPs), base stations, etc., which are not limited in the present disclosure.

[0046] It is understandable that the scenario proposed in R18 CE WI to consider introducing multiple PRACH transmissions in one RACH attempt. In the above multiple PRACH transmissions, PRACH retransmission may be initiated because the terminal does not receive a random access response or the terminal does not receive its corresponding RAPID or the terminal competition resolution fails. At this time, if the power boosting mechanism is to be introduced, the behavior of the terminal needs to be clarified, that is, it is necessary to determine under what conditions the terminal performs or does not perform power boosting.

[0047] In an embodiment of the present disclosure, the UE may determine whether to perform power boosting based on the configuration or indication information of the network device. For example, the UE receives the configuration or indication information of the network device, and the configuration information instructs the UE to perform power boosting during PRACH retransmission. The UE performs power boosting, i.e., the power boost counter is incremented by 1, and the PRACH channel will increase the transmission power by one step. The UE may also determine whether to perform power boosting based on a protocol agreement. For example, the protocol stipulates that even if the transmission power is reduced or the transmission is canceled due to power allocation in 3 of 8 PRACH transmissions, power boosting is still performed, i.e., the power boost counter is still incremented by 1.

[0048] It should be noted that the solution of the present disclosure can be applied to non-contention random access (CFRA) and contention random access (CBRA), and the present disclosure is not limited thereto.

[0049] In summary, according to the power boost determination method disclosed in the present invention, for multiple physical random access channel PRACH transmissions in a random access channel RACH attempt, the terminal determines whether to perform power boost based on the configuration information of the network device or based on the protocol agreement, and proposes a power boost mechanism under multiple PRACH transmissions, which clarifies the terminal behavior while ensuring PRACH coverage.

[0050] FIG2 is a flow chart of a method for determining a power boost according to an embodiment of the present disclosure. The method is executed by a UE and, based on the embodiment shown in FIG1 , as shown in FIG2 , the method may include the following steps.

[0051] S201: Receive configuration information sent by a network device.

[0052] The configuration information carries information indicating whether the UE performs power boosting.

[0053] Furthermore, the configuration information may be carried in a field of RRC signaling or DCI, for example, it may be directly configured in RRC or some dynamic indications may be carried in a field of DCI.

[0054] Furthermore, the configuration information can be implicit or explicit. For example, an explicit configuration message indicates that the power boost is performed when the indication information in the configuration message sent by the network device is 1, and a power boost is performed when the indication information in the configuration message sent by the network device is 0, and a power boost is not performed. For example, an implicit configuration message indicates that the configuration information is not received, or the configuration information does not carry information instructing the UE to perform a power boost, and a power boost is not performed.

[0055] S202: For multiple physical random access channel (PRACH) transmissions in one random access channel (RACH) attempt, determine whether to perform power boosting based on configuration information of a network device or based on a protocol agreement.

[0056] In some embodiments of the present disclosure, determining whether to perform a power boost based on configuration information of a network device includes: determining to perform a power boost in response to receiving configuration information, or in response to receiving a configuration message carrying information instructing the UE to perform a power boost; determining not to perform a power boost in response to not receiving configuration information, or in response to receiving a configuration message carrying information instructing the UE not to perform a power boost.

[0057] Among them, the configuration message sent by the network to the UE can directly carry dedicated configuration information instructing the UE to perform or not to perform power boost, or it can be other configuration messages sent by the network, which implicitly instruct the UE to perform or not to perform power boost by multiplexing the other configuration information! In other words, when initiating PRACH retransmission, if the terminal receives the configuration message from the base station, or the received configuration message carries information instructing the UE to perform power boost, the terminal determines to perform power boost. If the terminal does not receive the configuration message from the base station or the received configuration message does not carry information instructing the UE to perform power boost, the terminal determines not to perform power boost.

[0058] It is understandable that in R15, a RACH attempt only sends one PRACH. If the PRACH transmission power is reduced or the transmission is cancelled due to power allocation, it is determined that no power increase is performed when initiating PRACH retransmission.

[0059] Further, in the scenario where R18 CE WI considers introducing multiple PRACH transmissions for one RACH attempt, power allocation may cause the power of one or several PRACH transmissions in multiple PRACH transmissions to decrease, and / or one or several PRACH transmissions to be cancelled. At this time, the solution in this embodiment can be adopted to determine whether to perform power boosting based on the base station configuration or indication when a certain PRACH transmission is cancelled or the transmission power decreases.

[0060] Optionally, the configuration information sent by the network device may also carry a PRACH transmission count threshold P. It should be understood that in some alternative embodiments, the PRACH transmission count threshold P may be carried by other messages, and the present disclosure places no restrictions thereon.

[0061] Further, the PRACH transmission count threshold P includes a transmission cancellation count threshold K and / or a transmission power reduction count threshold Q. The UE can determine whether to perform power boosting for the next RACH attempt based on the transmission cancellation count threshold and / or the transmission power reduction count threshold configured by the base station. For example, when the number of cancelled PRACH transmissions exceeds the transmission cancellation threshold, the next RACH attempt does not perform power boosting, that is, the power boost counter pauses from incrementing by 1.

[0062] In some embodiments of the present disclosure, determining whether to perform power boosting based on protocol agreement includes: determining to perform power boosting when a first event stipulated by the protocol occurs.

[0063] Among them, the first event is that there are less than or equal to m PRACH transmissions among multiple PRACH transmissions whose transmission power decreases or transmission is cancelled due to power allocation, where the number of PRACH transmissions m is less than the number of transmissions n of multiple PRACH transmissions determined by the terminal, and the value of m is stipulated by the protocol.

[0064] For example, in the transmission of 4 PRACH transmissions in one RACH attempt, the number of transmissions of the 4 PRACH transmissions is 8. When there are less than or equal to m PRACH transmissions (including 1, 2, and 3 less than or equal to m PRACH transmissions) among the transmissions of the 4 PRACH transmissions whose transmission power decreases or transmission is cancelled due to power allocation, and the number of PRACH transmissions m is less than the number of transmissions 8 of multiple PRACH transmissions determined by the terminal, that is, when 1 < m < 8, the situation of the first event stipulated by the protocol occurs, and it is determined to perform power boosting during PRACH retransmission, that is, the power boost counter increments by 1.

[0065] In an alternative embodiment of the present disclosure, the method further includes: receiving the candidate transmission counts of multiple PRACH transmissions sent by the network device; determining n based on the multiple candidate transmission counts.

[0066] Specifically, the base station configures a set of data including multiple candidate transmission times for the terminal. The terminal can compare the measured received power of the reference signal with several thresholds to determine the number of transmission times n of multiple PRACH transmissions. For example, the data includes values ​​such as 2, 4, and 8. The received power of the reference signal obtained through measurement is within the third threshold interval, thereby determining that the number of transmission times n of multiple PRACH transmissions is 8.

[0067] It should be noted that, in some embodiments, after determining to perform a power boost based on the network configuration message, the UE may further determine whether the first event agreed upon in the protocol has occurred, and determine to perform a power boost if the first event agreed upon in the protocol has occurred. Alternatively, when the UE has not received the network configuration, it may determine whether the first event agreed upon in the protocol has occurred, and determine to perform a power boost if the first event agreed upon in the protocol has occurred.

[0068] In some embodiments of the present disclosure, determining whether to perform a power boost based on a protocol agreement further includes: determining not to perform a power boost when a second event agreed upon in the protocol occurs.

[0069] The second event is that, among the multiple PRACH transmissions, there is at least one PRACH transmission whose transmission power is reduced or the transmission is cancelled due to power allocation.

[0070] For example, if the number of transmissions of multiple PRACH transmissions is n, and the number of PRACH transmissions in which the transmission power is reduced or the transmission is canceled due to power allocation is m, when 1≤m≤n, it is determined that no power boost is performed, that is, the power boost counter is paused and incremented by 1.

[0071] It should be noted that, in some embodiments, after determining not to perform power boosting based on the network configuration message, the UE may further determine whether the second event agreed upon in the protocol occurs, and determine not to perform power boosting if the second event agreed upon in the protocol occurs. Alternatively, the UE may determine whether the second event agreed upon in the protocol occurs without receiving the network configuration, and determine not to perform power boosting if the second event agreed upon in the protocol occurs.

[0072] In summary, according to the power boost determination method disclosed in the present invention, it is clarified that for multiple physical random access channel PRACH transmissions of a random access channel RACH attempt, when the power of one or several PRACH transmissions in the multiple PRACH transmissions is reduced, and / or one or several PRACH transmissions are canceled, how the terminal performs power boosting in subsequent RACH attempts.

[0073] FIG3 is a flow chart of a method for determining a power boost according to an embodiment of the present disclosure. The method is executed by a UE and, based on the embodiments shown in FIG1 and / or FIG2 , as shown in FIG3 , may include the following steps.

[0074] S301 : For multiple physical random access channel (PRACH) transmissions in one random access channel (RACH) attempt, a PRACH transmission number threshold P is determined based on configuration information of a network device or based on a protocol agreement.

[0075] In an embodiment of the present disclosure, the UE may determine the PRACH transmission number threshold P based on the configuration information of the network device, where P may be sent by the network device alone, or may be carried in the configuration information sent by the network device and sent together with information indicating whether the UE performs power boosting. The UE may also determine the PRACH transmission number threshold P based on a protocol agreement, which is not limited by the present disclosure.

[0076] Furthermore, the PRACH transmission number threshold P may be a fixed value, or P=N / 2, P=N-offset, offset=1 / 2 / N / N-1, etc., which is not limited in the present disclosure.

[0077] S302: Determine the number of transmissions p of PRACH transmissions in which a third event occurs among multiple PRACH transmissions.

[0078] The third event is: PRACH transmission power is reduced or transmission is canceled due to power allocation.

[0079] S303: Determine whether to perform power boost based on the relationship between p and P.

[0080] In other words, when the PRACH transmission power is reduced or the transmission is canceled due to power allocation, the UE can determine whether to increase the power by comparing the PRACH transmission number threshold P and the number of transmissions p of the PRACH transmissions in which the transmission power is reduced or the transmission is canceled due to power allocation.

[0081] In some embodiments, the implementation scheme of step S303 includes: when p≤P is satisfied, determining to perform power boost; when p>P is satisfied, determining not to perform power boost.

[0082] In other words, when no more than P times of PRACH transmission are caused by power reduction or transmission cancellation due to power allocation, it is determined that power increase is to be performed, and the power increase counter is increased by 1. If more than P times of PRACH transmission are caused by power reduction or transmission cancellation, it is determined that power increase is not to be performed, and the power increase counter is suspended and increased by 1.

[0083] In some embodiments, P includes a power reduction number threshold Q and a transmission cancellation number threshold K, and p includes the number of PRACH transmissions q in which the transmission power is reduced due to power allocation and the number of PRACH transmissions k in which the transmission is canceled due to power allocation in multiple PRACH transmissions. At this time, the implementation plan of step S303 includes: when k≤K and q≤Q are both satisfied, determining to perform power raising; when any one of k>K and q>Q is satisfied, determining not to perform power raising.

[0084] In other words, this feasible implementation plan separates the two situations of PRACH transmission power reduction and PRACH transmission power cancellation, and determines whether to perform power raising through two thresholds including the power reduction number threshold Q and the transmission cancellation number threshold K. When the number of PRACH transmissions q due to transmission power reduction caused by power allocation does not exceed the power reduction number threshold Q, and the number of PRACH transmissions k due to transmission cancellation caused by power allocation does not exceed the transmission cancellation number threshold K, it is determined that power raising is to be performed, and the power raising counter is increased by 1; on the contrary, when either q exceeds Q or k exceeds K, it is determined that power raising is not to be performed, and the power raising counter is suspended and increased by 1.

[0085] In some embodiments, P includes a power reduction number threshold Q and a transmission cancellation number threshold K, and p includes the number q of PRACH transmissions in which the transmission power is reduced due to power allocation and the number k of PRACH transmissions in which the transmission is canceled due to power allocation in multiple PRACH transmissions. At this time, the implementation plan of step S303 also includes: when p≤P, q≤Q and k≤K are all satisfied, determining to perform power raising; when any one of p>P, q>Q, k>K is satisfied, determining not to perform power raising.

[0086] In other words, the feasible implementation scheme determines whether to perform power raising through three thresholds, including the PRACH transmission number threshold P, the power reduction number threshold Q, and the transmission cancellation number threshold K. When the number of PRACH transmissions q where the transmission power is reduced due to power allocation does not exceed the power reduction number threshold Q, and the number of PRACH transmissions k where the transmission is canceled due to power allocation does not exceed the transmission cancellation number threshold K, and the sum of q and k p does not exceed the PRACH transmission number threshold P, it is determined that power raising is performed and the power raising counter is incremented by 1; conversely, when any one of q exceeds Q, k exceeds K, and p exceeds P occurs, it is determined that power raising is not performed and the power raising counter is paused and incremented by 1.

[0087] It should be noted that the embodiments of the present disclosure can be implemented separately or in combination with the embodiment shown in Figure 2. For example, after determining to perform power boost based on the network configuration message, the UE needs to further determine whether to perform power boost based on the relationship between p and P. This disclosure is not limited.

[0088] In summary, according to the power boost determination method disclosed in the present invention, it is clarified that the UE can determine the PRACH transmission number threshold P based on the configuration information of the network device or based on the protocol agreement, and determine the number of transmissions p of at least one PRACH transmission in which the transmission power is reduced or the transmission is canceled due to power allocation among multiple PRACH transmissions, and then determine whether to perform power boost based on the relationship between p and P.

[0089] Figure 4 is a flow chart of a method for determining a power boost according to an embodiment of the present disclosure. The method is performed by a network device, as shown in Figure 4 , and may include the following steps. In the embodiments of the present disclosure, network devices include, but are not limited to, switches, routers, bridges, hubs, gateways, network interface cards (NICs), wireless access points (WAPs), base stations, and the like, and are not limited in this disclosure.

[0090] S401: Send configuration information to user equipment UE.

[0091] The configuration information carries information indicating whether the UE performs power boosting.

[0092] In the embodiments of the present disclosure, user equipment UE includes but is not limited to smart terminal devices, cellular phones, wireless devices, handsets, mobile units, vehicles, vehicle-mounted devices, etc., and is not limited in the present disclosure.

[0093] In the embodiments of the present disclosure, the configuration information may be carried in a field of RRC signaling or DCI, for example, it may be directly configured in the RRC or some dynamic indications may be carried in a field of the DCI.

[0094] Specifically, corresponding to the embodiment shown in FIG2 , for multiple physical random access channel PRACH transmissions in one random access channel RACH attempt, the network device sends configuration information to the UE, and the UE may determine whether to perform power boosting based on the configuration information of the network device.

[0095] Furthermore, the configuration information can be implicit or explicit. An explicit configuration message, for example, when the indication information in the configuration message sent by the network device is 1, determines to perform power boosting; when the indication information in the configuration message sent by the network device is 0, determines not to perform power boosting; an implicit configuration message, for example, when no configuration information is received, or in response to receiving a message carrying information instructing the UE not to perform power boosting, determines not to perform power boosting.

[0096] Optionally, the configuration information sent by the network device may carry the PRACH transmission number threshold P, and the network device may also send the PRACH transmission number threshold P to the UE separately. Correspondingly, in the embodiment shown in Figure 3, the UE can determine the PRACH transmission number threshold P by receiving the configuration information sent by the network device.

[0097] In some embodiments, the method further comprises: sending a candidate transmission number of a plurality of PRACH transmissions to the UE.

[0098] The candidate transmission number is used to assist the UE in determining the transmission number n of the multiple PRACH transmissions.

[0099] Specifically, corresponding to the embodiment shown in Figure 2, the network device sends multiple candidate transmission times of PRACH transmissions to the UE, the UE receives the multiple candidate transmission times of PRACH transmissions sent by the network device, and determines the transmission times n of the multiple PRACH transmissions based on the multiple candidate transmission times.

[0100] In summary, according to the power boost determination method disclosed in the present invention, the network device sends configuration information to the user equipment UE, wherein the configuration information carries information indicating whether the UE performs power boost. The UE can determine whether to perform power boost based on the configuration information, and proposes a power boost mechanism under multiple PRACH transmissions.

[0101] Figure 5 illustrates an interactive diagram of a method for determining a power boost according to an embodiment of the present disclosure. As shown in Figure 5 , this embodiment involves data / signaling interactions between a network device and a user equipment (UE) during the execution of a positioning measurement method. Based on the embodiments shown in Figures 1 through 4 , the method includes the following steps.

[0102] S501: A network device sends configuration information to a user equipment (UE).

[0103] The configuration information carries information indicating whether the UE performs power boosting.

[0105] Optionally, based on the configuration information of the network device, determining whether to perform a power boost includes: determining to perform a power boost in response to receiving configuration information, or in response to receiving a message carrying information instructing the UE to perform a power boost; determining not to perform a power boost in response to not receiving configuration information, or in response to receiving a message carrying information instructing the UE not to perform a power boost.

[0106] Optionally, based on the protocol agreement, determining whether to perform a power boost includes: determining to perform a power boost in the event of a first event agreed upon in the protocol, wherein the first event is: there are less than or equal to m PRACH transmissions among multiple PRACH transmissions, and the transmission power is reduced or the transmission is canceled due to power allocation, wherein the number of PRACH transmissions m is less than the number of transmissions n of the multiple PRACH transmissions determined by the terminal, and m is agreed upon by the protocol.

[0107] Optionally, the above method further includes: the network device sends multiple candidate transmission times of PRACH transmission to the UE, and the UE receives the multiple candidate transmission times of PRACH transmission sent by the network device; and determining n based on the multiple candidate transmission times.

[0108] Optionally, based on the protocol agreement, determining whether to perform power boosting includes: in the event of a second event agreed upon in the protocol, determining not to perform power boosting, wherein the second event is: there is at least one PRACH transmission among multiple PRACH transmissions whose transmission power is reduced or the transmission is canceled due to power allocation.

[0109] Optionally, determining whether to perform power boosting based on the configuration information of the network device or based on the protocol agreement also includes: determining a PRACH transmission number threshold P based on the configuration information of the network device or based on the protocol agreement; determining the number of PRACH transmissions p in which a third event occurs among multiple PRACH transmissions; and determining whether to perform power boosting based on the relationship between p and P, wherein the third event is: the PRACH transmission power is reduced or the transmission is canceled due to power allocation.

[0110] Optionally, the above method further includes: the network device sending a PRACH transmission number threshold P to the UE.

[0111] Optionally, based on the relationship between p and P, determining whether to perform power boost includes: when p≤P is satisfied, determining to perform power boost; when p>P is satisfied, determining not to perform power boost.
