Description

Technical Field

[0001] This invention relates to the field of communications, and more specifically, to a method for determining transmission power, reporting power margin, and receiving data. Background Technology

[0002] In existing 5G New Radio (NR), the Power Headroom Report (PHR) is a power headroom report submitted by the User Equipment (UE) to the serving cell. It helps the gNB determine the UE's uplink power headroom for power control and resource scheduling. In 5G NR, a serving cell only allows the transmission of one Physical Uplink Shared Channel (PUSCH) on a single time-domain resource. This means that a terminal does not support frequency division multiplexing, space division multiplexing, or code division multiplexing of multiple PUSCHs on a single time-domain resource of a serving cell, nor does it support frequency division multiplexing of PUSCH and Physical Uplink Control Channel (PUCCH).

[0003] In 6G, a serving cell can activate multiple Bandwidth Parts (BWPs). Each BWP can transmit one PUSCH or PUCCH, and even within a single BWP, multiple PUSCHs may be transmitted using frequency division multiplexing, or both PUSCHs and PUCCHs may be transmitted simultaneously. Therefore, the 5G PHR scheme makes it impossible for the base station to accurately determine the remaining power margin after transmitting multiple PUSCHs in this scenario. This makes it difficult to accurately control the power of multiple frequency-division multiplexed PUSCHs within a serving cell, thus affecting uplink transmission performance and uplink system capacity. Summary of the Invention

[0004] This invention provides a method for determining transmission power, reporting and receiving power margin, to at least solve the problem that existing PHR schemes in related technologies cannot meet the needs of transmission scenarios and affect transmission performance and system capacity.

[0007] According to another embodiment of the present invention, a method for receiving power margin is provided, applied to a base station, comprising: enabling the simultaneous transmission of multiple PUSCH functions in a bandwidth portion BWP, the UE cell, or a carrier in a time slot; or enabling the multi-PUSCH power margin reporting function in a bandwidth portion BWP, the UE cell, or a carrier in a time slot; or sending a multi-PUSCH power margin reporting trigger command; receiving a power margin report PHR reported by a user equipment UE, wherein the PHR contains the remaining power margin of the UE after transmitting the multiple PUSCHs; wherein the remaining power margin of the UE after transmitting the multiple PUSCHs is the power difference between the maximum transmission power of the UE and the sum of the transmission powers of the multiple PUSCHs.

[0017] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0019] In related technologies, 5G NR defines three PHR types, each applicable to different scenarios. The reporting trigger conditions for PHR include multiple scenarios, ensuring that the gNB can promptly obtain the UE's power status, thereby enabling effective resource allocation and power control. The information for the three PHR types is as follows:

[0020] Type 1: The difference between the nominal maximum transmit power of the UE in each active serving cell and the estimated transmit power on the Uplink Shared Channel (UL-SCH).

[0021] Type 2: The difference between the UE's nominal maximum transmit power and the estimated power of the UL-SCH and PUCCH transmitted on a special serving cell (SpCell) of another Media Access Control (MAC) entity (i.e., only in the case of Extended Dual Connectivity (EN-DC) for the Evolved Universal Terrestrial Radio Access (e-UTRA) MAC entity).

[0022] Type 3: The difference between the nominal maximum transmit power of the UE in each active serving cell and the estimated transmit power of the Sounding Reference Signal (SRS).

[0023] The reporting triggers for PHR include the following situations:

[0024] (1) Timeout of the timer (phr-ProhibitTimer) corresponding to the target BWP: When there are uplink resources for new transmissions on the MAC, and the phr-ProhibitTimer has expired or has expired, if the path loss of at least one activated cell of any MAC entity changes more than the path loss of that cell during the previous PHR transmission on this MAC.

[0025] (2) UE timer (phr-PeriodicTimer) timeout: periodically report PHR.

[0026] (3) Configure or reconfigure PHR function: When the upper layer configures or reconfigures PHR function, this action cannot disable PHR function.

[0027] (4) Uplink SCell cell activation: Uplink SCell cell activation is configured in any MAC entity.

[0028] (5) Adding or changing PScells.

[0029] (6) Uplink new transmission resource conditions: When a MAC entity has resources available for uplink new transmission, and the phr-ProhibitTimer times out or has already timed out, for any serving cell with uplink configured and activated on any MAC, if this cell has uplink resources for transmission or has PUCCH transmission, and the change in the power backoff of this cell compared to the power backoff value when the PHR was reported last time this MAC entity had PUSCH or PUCCH transmission is greater than the power difference change threshold (phr-Tx-PowerFactorChange), then PHR is triggered.

[0030] When one of the above triggering conditions is met, the UE begins to prepare to report the PHR.

[0031] The existing 5G NR PHR reporting method based on active serving cell is no longer suitable for 6G scenarios involving multiple PUSCHs transmitted within a single serving cell, simultaneous transmission of PUSCH and PUCCH, or transmission of Uplink Control Information (UCI) on a dedicated PUSCH. 6G UCI transmission on PUSCH differs from the 5G method of multiplexing UCI and data on PUSCH. It may use CG PUSCH to transmit periodic Channel State Information (CSI), or PUSCH to transmit only Hybrid Automatic Repeat Request – Acknowledgement (HARQ-ACK). In these cases, the PHR of the PUSCH carrying UCI needs to be defined separately, different from the PHR of the 5G PUSCH. Therefore, it is necessary to define new PHR reporting types, as well as the triggering conditions and reporting methods for these new PHRs.

[0032] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 1 This is a hardware structure block diagram of a mobile terminal for the transmission power determination method according to an embodiment of the present invention. Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0033] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the transmission power determination method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0034] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module, used for wireless communication with the Internet.

This solves the problem that the PHR scheme in related technologies cannot meet the needs of transmission scenarios and affects transmission performance and system capacity, thus achieving the effect of meeting the needs of transmission scenarios and improving transmission performance.

[0067] This embodiment provides a method for reporting power margin, applied to User Equipment (UE). Figure 3 This is a flowchart of the power margin reporting method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0068] Step S302: When enabling the function of simultaneous transmission of multiple PUSCHs in a BWP, UE cell, or carrier in a time slot, or when enabling the multi-PUSCH power margin report reporting function in a BWP, UE cell, or carrier in a time slot, or when sending a multi-PUSCH power margin report trigger command, the remaining power margin of the UE after transmitting the multiple PUSCHs is determined based on the power difference between the UE's maximum transmission power and the sum of the transmission powers of the multiple PUSCHs.

[0069] Step S304: Report the remaining power margin through the Power Margin Report (PHR).

[0072] Type B: PHR = P MAX -P PUSCH-UCI -P PUSCH , where P MAX P is the maximum transmit power of the UE. PUSCH-UCI For the transmit power of the PUSCH used to transmit UCI, P PUSCH-UCI The transmit power of PUSCH;

[0073] Type C: PHR = P MAX -P PUSCH,0 -P PUSCH,1 , where P PUSCH,0 To transmit the transmission power of the first PUSCH, P PUSCH,1 For transmitting the power of the second PUSCH;

[0075] In one exemplary embodiment, the type of Power Headroom Report (PHR) is selected based on the current number of transmitted PUSCHs; or, the type of PHR is selected based on configuration signaling from the base station; or, the type of PHR is selected based on a trigger command for the PHR.

[0076] In an exemplary embodiment, when the number of transmitted PUSCHs is less than the number of PUSCHs corresponding to the type of Power Headroom Report (PHR), the power headroom calculation parameters for PUSCHs other than the transmitted PUSCHs are determined by predefined values ​​or signaling configuration values.

[0077] In an exemplary embodiment, reporting the remaining power margin via a Power Margin Report (PHR) includes: the existence of uplink resources for new data transmission on the MAC of the target BWP, the timer phr-Timer corresponding to the target BWP reaching a preset first time threshold, the path loss change of the target BWP being greater than a preset path loss change threshold, and reporting at least one Power Margin Report (PHR).

[0078] Alternatively, when the UE's timer phr-PeriodicTimer reaches a preset second time threshold, the target BWP's power margin report PHR is periodically reported.

[0079] Alternatively, if the PHR reporting function is reconfigured in the high-level configuration message from the base station and the new configuration does not disable the PHR function, then all power margin reports (PHR) corresponding to the activated BWPs will be reported.

[0080] Alternatively, if a new target BWP is activated, a Power Headroom Report (PHR) corresponding to the new target BWP is reported according to the high-level configuration message of the base station.

[0081] Alternatively, if there are uplink resources available for new data transmission on the MAC, and the power difference change of the serving cell on any activated MAC is greater than the preset power difference change threshold, a Power Margin Report (PHR) is submitted.

[0082] Alternatively, after the UE completes PUSCH data transmission and the uplink power margin is greater than the preset margin threshold, the corresponding power margin report PHR is reported.

[0083] Alternatively, if the number of PUSCHs transmitted simultaneously on multiple BWPs exceeds a preset value x, and y of the simultaneously transmitted PUSCHs need to be retransmitted, a Power Margin Report (PHR) is submitted, where y ≤ x, and x and y are both positive integers.

[0084] Alternatively, in the event of a retransmission of the PUSCH used for transmitting UCI, a corresponding power headroom report (PHR) is submitted.

[0085] This embodiment provides a method for receiving power margin, applied to a base station. Figure 4 This is a flowchart of the power margin receiving method according to an embodiment of the present invention, as follows: Figure 4 As shown, the process includes the following steps:

[0086] Step S402: When enabling the function of simultaneous transmission of multiple PUSCHs in a BWP, UE cell, or carrier in a time slot, or when enabling the multi-PUSCH power margin report reporting function in a BWP, UE cell, or carrier in a time slot, or when sending a multi-PUSCH power margin report trigger command, the power margin report PHR reported by the UE is received. The PHR contains the remaining power margin of the UE after transmitting multiple PUSCHs. The remaining power margin of the UE after transmitting multiple PUSCHs is the power difference between the UE's maximum transmission power and the sum of the transmission powers of multiple PUSCHs.

[0087] In one exemplary embodiment, the Power Headroom Report (PHR) type includes at least one of the following:

[0088] Type B: PHR = P MAX -P PUSCH-UCI -P PUSCH , where P MAX P is the maximum transmit power of the UE. PUSCH-UCI For the transmit power of the PUSCH used to transmit UCI, P PUSCH-UCI The transmit power of PUSCH;

[0089] Type C: PHR = P MAX -P PUSCH,0 -P PUSCH,1 , where PPUSCH,0 To transmit the transmission power of the first PUSCH, P PUSCH,1 For transmitting the power of the second PUSCH;

[0090] Type D: Where h is the maximum number of PUSCHs transmitted simultaneously, or the assumed number of PUSCHs transmitted, or the current number of PUSCHs transmitted, or a signaling configuration value; P PUSCH,i The transmit power for transmitting the i-th PUSCH.

[0091] In one exemplary embodiment, before receiving the PHR reported by the UE, the method further includes configuring the type of the PHR reported by the UE.

[0092] In one exemplary embodiment, before receiving the PHR reported by the UE, the method further includes: configuring calculation parameters for the remaining power margin.

[0093] In one exemplary embodiment, before receiving the PHR reported by the UE, the method further includes: sending a triggering signaling for the PHR, wherein the triggering signaling includes the type of the PHR reported by the UE.

[0094] In one exemplary embodiment, a bitmap method is used to trigger the UE to report PHRs, wherein each bit corresponds to a type of PHR, or the number of types of PHRs reported.

[0150] Example 5

[0151] In this embodiment, in order to better obtain the remaining power margin after transmitting the PUSCH carrying UCI, so that the network can better schedule the PUSCH transmission, a dedicated PHR type is defined for the PUSCH that transmits uplink control information.

[0155] Example 6

[0157] In this embodiment, the remaining power margin of the UE after transmitting the multiple PUSCHs is determined based on the power difference between the UE's maximum transmit power and the sum of the transmit powers of the multiple PUSCHs. The remaining power margin is then reported through a Power Margin Report (PHR). A dedicated PHR type is defined for transmitting multiple PUSCHs, including at least one of the following:

[0162] In this embodiment, when the number of transmitted PUSCHs is less than the number of PUSCHs corresponding to the type of Power Headroom Report (PHR), the power headroom calculation parameters of PUSCHs other than the transmitted PUSCHs are determined by predefined values ​​or signaling configuration values.

[0163] Example 7

[0164] In this embodiment, PHRs are reported based on activated BWPs. Each activated BWP reports one PHR, and PHR configuration is performed for each activated BWP, including the PHR reporting period, PHR reporting trigger threshold, and the maximum transmission power corresponding to that BWP.

Here, the PHR can be all configured PHRs, or one or more of type APHR, type B PHR, type C PHR, and type D PHR reported.

[0165] In this embodiment, the UE reports PHR in one or more of the following ways:

[0166] (1) There are uplink resources for new data transmission on the MAC of the target BWP, and the timer phr-Timer corresponding to the target BWP reaches the preset first time threshold (i.e., the phr-Timer has timed out or has already timed out), and the path loss change of the target BWP is greater than the preset path loss change threshold, and at least one power margin report PHR is reported.

[0167] In this embodiment, when the path loss change of the target BWP is greater than the preset path loss change threshold, that is, when the path loss of the target BWP is greater than the path loss of the target BWP during the previous PHR transmission on this MAC, the change is greater than phr-Tx-PowerFactorChange, all types of PHR reporting are triggered, or one or more of type APHR, type B PHR, type C PHR, and type D PHR are reported.

[0168] In this embodiment, when a MAC entity has resources available for uplink transmission, and the phr-Timer times out or has already timed out, for any serving cell with an uplink configured and activated on any MAC, if this cell has uplink resources for transmission or has UCI-specific PUSCH transmission, and the change in the power backoff of this cell compared to the power backoff value when the PHR was reported last time this MAC entity had PUSCH or UCI-specific PUSCH transmission is greater than phr-Tx-PowerFactorChange, then PHR is triggered.

[0169] (2) Alternatively, when the UE's timer phr-PeriodicTimer reaches a preset second time threshold (i.e., phr-PeriodicTimer times out), the target BWP's power margin report PHR is periodically reported. Here, PHR can be any type of PHR report, or one or more of type APHR, type B PHR, type C PHR, and type D PHR.

[0170] (3) Alternatively, if the PHR reporting function is reconfigured in the high-layer configuration message from the base station and the new configuration does not disable the PHR function, report the power margin report PHR corresponding to all activated BWPs.

[0171] (4) Alternatively, when a new target BWP is activated, a Power Headroom Report (PHR) corresponding to the new target BWP is reported according to the high-layer configuration message of the base station. Here, PHR can be any type of PHR report, or one or more of the following: type APHR, type BPHR, type C PHR, and type D PHR.

[0172] (5) Alternatively, if there are uplink resources available for new data transmission on the MAC and the power difference change of the serving cell on any activated MAC is greater than the preset power difference change threshold, a power margin report (PHR) shall be submitted.

[0173] (6) Alternatively, after the UE completes PUSCH data transmission and the uplink power margin is greater than the preset margin threshold, the UE reports the corresponding power margin report (PHR). The PHR is of type D PHR, or type APHR, or multiple PHRs of type APHR, type BPHR, type C PHR, and type D PHR are reported together.

[0174] (7) Alternatively, if the number of PUSCHs transmitted simultaneously on multiple BWPs exceeds a preset value x, and y of the simultaneously transmitted PUSCHs need to be retransmitted, a Power Headroom Report (PHR) is submitted, where y ≤ x, and x and y are both positive integers, for example, x is 1, 2, 3, or 4. The PHR is one or more of the following types: APHR, B PHR, C PHR, and D PHR, reported together.

[0175] (8) Alternatively, in the case of retransmission of the PUSCH used for transmitting UCI, a corresponding power headroom report (PHR) shall be reported. Wherein, the PHR is type D PHR, or type APHR, or multiple PHRs of type APHR, type B PHR, type C PHR, and type DPHR shall be reported together.

[0176] In this embodiment, the uplink power margin triggering signaling includes uplink power margin types. For example, it uses a bitmap method to trigger the UE to report PHR, where each bit corresponds to a type of PHR; or, it corresponds to the number of reported PHR types. For example, the specific uplink power margin types are determined according to a predefined order and number (e.g., the first m, etc.).
