Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a method, apparatus, terminal and storage medium for determining transmission power. Background Technology

[0002] Protocols related to demodulation reference signal (DMRS) bundling transmission technology require that multiple transmissions maintain power consistency and phase continuity so that the network can jointly perform channel estimation based on multiple uplink transmissions, thereby improving reception performance.

[0003] However, when the User Equipment (UE) is operating within the DMRS bundling time window, in order to meet the protocol requirements, it may adjust its power class during a certain evaluation period due to the duty cycle of the uplink transmission symbols, and thus adjust the corresponding uplink transmission power. This will cause the UE to be unable to maintain power consistency within the time window, which will in turn reduce the performance of the receiver's demodulation through joint channel estimation and affect coverage. Summary of the Invention

[0027] This application addresses the deficiency in existing technologies where UE power consistency cannot be guaranteed during the DMRS bundling time window when the UE adjusts its power according to the duty cycle. By determining and setting a continuously constant transmission power within the DMRS bundling time window based on first information before starting joint channel estimation or DMRS bundling, the application ensures consistent UE transmission power during subsequent joint channel estimation or DMRS bundling processes, thereby guaranteeing the performance of demodulation by the receiver through joint channel estimation. The following detailed description, in conjunction with the accompanying drawings, illustrates the transmission power determination method, apparatus, terminal, and storage medium provided in this application through various embodiments and application scenarios.

[0028] Figure 2 This is a flowchart illustrating a method for determining transmission power provided in an embodiment of this application. This method can be executed by a terminal, which may specifically be... Figure 1 Terminal 101 is shown in the image. (As shown in the image...) Figure 2 As shown, the method includes:

[0029] Step 201: Based on the first information, the terminal determines the first transmission power to be applied within the first time window.

[0030] The first time window is a duration configured for joint channel estimation or for the terminal to perform demodulation reference signal (DMRS) bundled transmission, and the first transmit power remains fixed or varies within a preset threshold range during the duration of the first time window.

[0031] This can be understood as follows: In order to avoid the problem that the terminal cannot guarantee power consistency within the first time window of joint channel estimation or DMRS bundling when adjusting the power level according to the existing protocol, the embodiments of this application determine and set the first transmission power that the terminal will use during the entire first time window duration of joint channel estimation or DMRS bundling in advance based on the first information obtained before joint channel estimation or DMRS bundling. The first transmission power can be the configured transmission power.

[0032] It should be understood that, in the embodiments of this application, when a first transmission power is set, the value of the first transmission power remains fixed throughout the entire duration of the first time window, or, depending on the actual application scenario, the magnitude of change is allowed to be within a preset threshold range. The preset threshold can be determined by some power requirements or other indicators, enabling the terminal to maintain power consistency. For example, the parameter `aggregate power tolerance` can be used to specify the tolerable power variation within a certain time period.

[0033] In the uplink transmission application of this application embodiment, the receiving end can be a network-side device, such as a base station, while the terminal acts as the sending end.

[0034] The method for determining transmission power provided in this application embodiment allows the UE to determine and set a transmission power that remains constant within the time window of joint channel estimation or DMRS bundling based on first information before starting joint channel estimation or DMRS bundling. This ensures the consistency of the UE's transmission power when processing is performed according to this transmission power during the subsequent actual joint channel estimation or DMRS bundling process, thereby guaranteeing the performance of the receiver in demodulating through joint channel estimation.

[0035] In the above embodiments, the first information is a parameter or information related to determining the first transmission power of the terminal. Optionally, the method further includes determining the first information using at least one of the following methods:

[0036] The determination is based on the first indication information received by the terminal, wherein the first indication information is indication information associated with bundled transmission of Joint Channel Estimation or Demodulation Reference Signal (DMRS);

[0037] Based on the first configuration information, the first duty cycle determined by the terminal, and / or the first reporting information in the terminal capability reporting;

[0038] The first configuration information is used to indicate at least one of the following:

[0039] Whether to configure the first maximum output power;

[0040] The value of the first maximum output power configured;

[0041] The first maximum output power is used to limit the maximum transmission power of the terminal;

[0042] The first duty cycle is the duty cycle of the terminal for uplink transmission of available time slots or symbols within the first time window, or it is the duty cycle of the terminal at any set time within the first time window;

[0043] The first reported information is used to indicate at least one of the following:

[0044] Should the uplink duty cycle threshold be reported?

[0045] The reported uplink duty cycle threshold value.

[0046] This can be understood as follows: before determining the first transmission power based on the first information, the terminal can first determine the first information according to the processing methods listed above. Specifically, based on different combinations of the above processing methods, the first information can be determined through the following three methods:

[0047] First, before entering the first time window, the terminal may receive indication information related to joint channel estimation or DMRS bundling; this indication information can be referred to as first indication information. Based on this first indication information, first information can be generated.

[0048] Optionally, the first indication information includes at least one of the following:

[0049] Enable indication for bundled transmission of joint channel estimation or demodulation reference signal (DMRS);

[0050] Signaling indications (including explicit or implicit signaling indications) used to configure the first time window;

[0051] Enable indication for maintaining power consistency.

[0052] It can be understood that, depending on the actual application, the first indication information in this application embodiment can be any one or any combination of the above-mentioned types of indication information. For example, if the terminal receives an enable indication for maintaining power consistency, it can directly use it as the first indication information; if the terminal receives both an enable indication for maintaining power consistency and a signaling indication for configuring a first time window, it can determine one of them as the first indication information through certain decision-making.

[0053] Alternatively, the terminal can determine the uplink duty cycle (referred to as the first duty cycle) in advance by predicting or assuming that all time slots within the first time window are available for uplink transmission, or by determining the available uplink time slots within the first time window based on certain RRC signaling or scheduling signaling, or by determining the available uplink time slots within the first time window based on the uplink available time slot pattern. Simultaneously, the terminal can obtain first configuration information and the first reporting information in the terminal's capability reporting. The first information can be determined through the aforementioned first duty cycle, first configuration information, and / or first reporting information.

[0054] The first reported information indicates the reporting status of the uplink duty cycle threshold, including whether the duty cycle threshold is reported and / or what the reported duty cycle threshold is. For example, whether the UE capability reporting message includes the parameter `maxUplinkDutyCycle-PC2-FR1`, and if so, what its value is. The parameter `maxUplinkDutyCycle-PC2-FR1` belongs to a specific class's field, and its value is used to limit the uplink duty cycle threshold for terminals supporting the default power level and the second power level. In other words, it specifies the maximum uplink duty cycle for a terminal supporting the second power level on a given band under FR1. The configurable value range for the maxUplinkDutyCycle-PC2-FR1 field can be {60%, 70%, 80%, 90%, 100%}, and the evaluation period for the maxUplinkDutyCycle-PC2-FR1 field is specified to be no less than one radio frame.

[0055] The first configuration information indicates the configuration status of the first maximum output power, including whether the first maximum output power is configured and / or the configured first maximum output power value. Optionally, the first maximum output power is one of the following:

[0056] The maximum output power of adjacent cells (such as NR cells) in the same frequency range;

[0057] The maximum output power of adjacent cells (such as NR cells) with the same carrier frequency;

[0058] The maximum transmit power allowed for the current serving cell.

[0059] The first configuration information includes, for example, whether the parameter p-Max is configured, and if so, its value. Here, p-Max represents the maximum output power of intra-frequency neighboring NR cells, the maximum output power of adjacent NR cells at the same carrier frequency, or the maximum allowed transmission power of the currently serving cell. Its value range can be [-30…33], in dBm.

[0060] The first duty cycle is the available symbol duty cycle determined by the terminal within the first time window. Optionally, the first duty cycle is the duty cycle of the available time slots or symbols for uplink transmission by the terminal within the first time window, or it is the duty cycle of the terminal at any time set within the first time window.

[0061] The available time slots or symbols for the uplink transmission are determined based on at least one of the following signaling:

[0062] tdd-UL-DL-ConfigurationCommon;

[0063] tdd-UL-DL-ConfigurationDedicated;

[0064] ssb-PositionsInBurst;

[0065] Indication of timing configuration based on synchronization signal block (SS / PBCH block, SSB) measurement (SMTC);

[0066] CORESET0 in the Type0-PDCCH CSS collection.

[0067] This can be understood as the terminal determining the first duty cycle based on the duty cycle of available uplink transmission time slots or symbols within the first time window, and / or the duty cycle at any set time within the first time window. The available uplink transmission time slots or symbols are further determined based on one or more of the signaling codes listed above. Specifically, the signaling code tdd-UL-DL-ConfigurationCommon indicates the uplink and downlink frame structure configuration of the cell-level Time Division Duplex (TDD) system; the signaling code tdd-UL-DL-ConfigurationDedicated indicates the uplink and downlink frame structure configuration of the dedicated / user-level TDD system; and the signaling code ssb-PositionsInBurst indicates the SSB candidate set position.

[0068] Alternatively, the terminal may, based on generating a first message based on the first instruction information and determining the first information based on the first duty cycle, the first configuration information and / or the first reporting information, determine one of them as the first information through a certain decision.

[0069] In this embodiment of the application, the first information is determined by the first indication information received by the terminal and / or the configuration of the first maximum output power, the first duty cycle determined by the terminal and / or the reporting of the uplink duty cycle threshold, so that the first transmission power determined according to the first information maintains the consistency of the terminal transmission power within the first time window.

[0070] Optionally, the first information is the first target power level and / or the second target power level applied by the terminal within the first time window;

[0071] Wherein, the first target power level is used to set the configured first transmit power, and the power requirement or radio frequency index corresponding to the second target power level is used to apply to the first target power level.

[0072] It can be understood that, in the process of determining the first transmission power based on the first information in the embodiments of this application, since the first transmission power is related to the power level of the terminal application, the terminal will also determine and set the target power level of the terminal application within the first time window.

[0073] Specifically, the terminal can determine the target power level directly used for setting the first transmit power using the aforementioned method of determining the first information, and use this as the first target power level, which is the first information. Alternatively, it can determine a second target power level using the same method, and the power requirements or RF specifications corresponding to this second target power level are applied to the first target power level; the second target power level can also be used as the first information. Alternatively, it can simultaneously determine the first target power level and the second target power level to determine the corresponding power requirements and RF specifications and to set the configured transmit power.

[0074] In other words, the terminal can determine a first target power level used within a first time window, which is used to set the configured transmission power; and / or, it can also determine a second target power level used within a first time window, where the power requirements corresponding to the second target power level are applied to the first target power level, and both the first and second target power levels can be used as first information.

[0075] Here, "configured" means that the actual transmission power used can be determined by the configured transmission power in combination with other related processes. In this embodiment of the application, the first transmission power can be set according to the determined target power level.

[0076] It should be noted that the first target power level and the second target power level can correspond to the same power class.

[0077] This application embodiment determines the target power level related to the configured transmission power, which makes it easier and faster to set the configured transmission power, and complies with existing protocol provisions, making maintenance convenient.

[0078] Optionally, the terminal supports a default power level, or the terminal supports a second power level in addition to the default power level; wherein the maximum output power of the second power level is higher than the maximum output power of the default power level.

[0079] It can be understood that the method for determining the transmission power in this application embodiment is applicable not only to the case where the terminal only supports the default power class, but also to the case where the terminal supports a second power class with a higher maximum output power than the default power class. As is known in the prior art, a terminal can currently support a maximum of two power classes in a certain band, but the solution in this application embodiment is also applicable to scenarios where the terminal supports more power classes. That is, the technical solution in this application embodiment is also applicable to scenarios where the terminal supports a second power class in addition to the default power class, and the maximum output power of the second power class is higher than the maximum output power of the default power class.

[0080] By limiting the applicable scenarios to multiple power levels, the embodiments of this application are more scalable and have a wider range of applications.

[0081] Optionally, when the terminal supports a default power level and a second power level, and the first information is determined based on the first configuration information, the first duty cycle, and / or the first reporting information, the terminal determines the first target power level, including:

[0082] If a first condition is met, the terminal determines any of the second power levels as the first target power level; otherwise, it determines the default power level as the first target power level, wherein the first condition includes at least one of the following:

[0083] The terminal does not include the uplink duty cycle threshold in its capability reporting, and the first duty cycle is greater than 50%.

[0084] The terminal does not include the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than 50%, and the first maximum output power is not configured.

[0085] The terminal does not include the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than 50%, and the configured first maximum output power is higher than the maximum output power corresponding to the default power level.

[0086] The terminal includes the uplink duty cycle threshold in its capability reporting, and the first duty cycle is greater than the uplink duty cycle threshold;

[0087] The terminal includes the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than the uplink duty cycle threshold, and the first maximum output power is not configured.

[0088] The terminal includes the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than the uplink duty cycle threshold, and the configured first maximum output power is higher than the maximum output power corresponding to the default power level.

[0089] It can be understood that, based on the above embodiments, the embodiments of this application are also applicable to scenarios where the terminal supports a second power level in addition to the default power level. In this scenario, when the first information is determined based on the first configuration information, the first duty cycle, and / or the first reporting information, the first target power level is determined, which may include, for example, the following situations:

[0090] First, the terminal determines the aforementioned second power level as the first target power level under the following circumstances:

[0091] (1) The UE capability report does not include the field maxUplinkDutyCycle-PC2-FR1, and,

[0092] First duty cycle greater than 50%,

[0093] Alternatively, the first duty cycle is not greater than 50% and the first maximum output power is not configured.

[0094] Alternatively, the first duty cycle is not greater than 50% and the configured first maximum output power is higher than the maximum output power corresponding to the default powerclass;

[0095] (2) The UE capability report includes the field maxUplinkDutyCycle-PC2-FR1, and,

[0096] The first duty cycle is greater than the threshold specified by the field maxUplinkDutyCycle-PC2-FR1.

[0097] Alternatively, if the first duty cycle is not greater than the threshold specified by the domain maxUplinkDutyCycle-PC2-FR1 and the first maximum output power is not configured,

[0098] Alternatively, the first duty cycle is not greater than the threshold specified by the domain maxUplinkDutyCycle-PC2-FR1 and the first maximum output power is configured to be higher than the maximum output power corresponding to the default power class.

[0099] Secondly, in all other cases, the terminal determines the default power class as the first target power level.

[0100] Optionally, when the terminal supports a default power level and a second power level, and the first information is determined based on the first configuration information, the first duty cycle, and / or the first reporting information, the terminal determines the second target power level, including:

[0101] If the second condition is met, the terminal determines any of the second power levels as the second target power level; otherwise, it determines the default power level as the second target power level. The second condition includes at least one of the following:

[0102] The terminal does not include the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than 50%, and the first maximum output power is not configured.

[0103] The terminal does not include the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than 50%, and the configured first maximum output power is higher than the maximum output power corresponding to the default power level.

[0104] The terminal includes the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than the uplink duty cycle threshold, and the first maximum output power is not configured.

[0105] The terminal includes the uplink duty cycle threshold in its capability reporting, and the first duty cycle is not greater than the uplink duty cycle threshold, and the configured first maximum output power is higher than the maximum output power corresponding to the default power level.

[0106] It can be understood that, based on the above embodiments, the embodiments of this application are also applicable to scenarios where the terminal supports a second power level in addition to the default power level. In this scenario, when the first information is determined based on the first configuration information, the first duty cycle, and / or the first reporting information, the second target power level is determined, which may include, for example, the following situations:

[0107] First, the terminal determines the aforementioned second power level as the second target power level under the following circumstances:

[0108] (1) The UE capability report does not include the field maxUplinkDutyCycle-PC2-FR1, and,

[0109] The first duty cycle is no greater than 50% and the first maximum output power is not configured.

[0110] Alternatively, the first duty cycle is not greater than 50% and the configured first maximum output power is higher than the maximum output power corresponding to the default powerclass;

[0111] (2) The UE capability report includes the field maxUplinkDutyCycle-PC2-FR1, and,

[0112] The first duty cycle is not greater than the threshold specified by the domain maxUplinkDutyCycle-PC2-FR1 and no first maximum output power is configured.

[0113] Alternatively, the first duty cycle is not greater than the threshold specified by the domain maxUplinkDutyCycle-PC2-FR1 and the configured first maximum output power is higher than the maximum output power corresponding to the default power class.

[0114] Secondly, in all other cases, the terminal determines the default power class as the second target power level.

[0115] This application embodiment determines the target power level used by the UE within the joint channel estimation / DMRS bundling time window based on the duty cycle corresponding to the available uplink transmission slots / symbols, the configuration of the first maximum output power, and / or the terminal's reporting of the uplink duty cycle threshold in capability reporting. This can maintain the consistency of UE power within the time window, ensure the demodulation performance of the receiver's joint channel estimation, and improve coverage capability.

[0116] Optionally, when the terminal supports a default power level and a second power level, and the first information is determined based on the first indication information, the terminal determines the first information by:

[0117] When the terminal performs uplink transmission of demodulation reference signal (DMRS) bundled transmission within the first time window, or when the receiving end of the demodulation reference signal (DMRS) bundled transmission performs joint channel estimation within the first time window, the terminal determines the default power level as the first target power level and / or the second target power level based on the first indication information, or determines any second power level as the first target power level and / or the second target power level.

[0118] It can be understood that, based on the above embodiments, the embodiments of this application are also applicable to scenarios where the terminal supports a second power level in addition to the default power level. In this scenario, when the first information is determined based on the first indication information, determining the first target power level and / or the second target power level may include, for example,:

[0119] The terminal first determines whether it is in an uplink transmission scenario involving DMRS bundling / joint channel estimation within the first time window. If so, the terminal determines that the default power class is the first target power level and / or the second target power level; or, the terminal determines that among the power classes supported by the UE, another power class besides the default power class is the first target power level and / or the second target power level. Otherwise, the terminal determines the first target power level according to the method specified in the existing protocol.

[0120] The embodiments of this application determine the target power level of the terminal based on the first indication information, and can set the first transmission power to be used by the terminal in the first time window before entering the first time window, so as to ensure the consistency of transmission power in the terminal performing DMRS bundled transmission or the receiver performing joint channel estimation.

[0121] For example, suppose the UE supports two power classes, power class 2 and power class 3, and it is known that power class 3 is the default power class. The TDD frame structure used for transmission is "DDSUUDDDSU". The threshold specified by the maxUplinkDutyCycle-PC2-FR1 field in the UE capability is 60%, and the first maximum output power is not configured.

[0122] If the receiving end (e.g., base station) of the data transmission is configured with PUSCH repetition transmission: repetitiontype A, repetition count of 16, then after the UE receives the scheduling authorization, it will perform the corresponding PUSCH repetition transmission in 16 consecutive time slots starting from time slot n. Before transmission, the UE needs to determine the target power level to be used:

[0123] If the UE calculates the uplink available time slot duty cycle to be 6 / 16 based on tdd-UL-DL-ConfigurationCommon, then the first target power level can be determined as power class 2, that is, the transmission power configured using power class 2.
