Background Art

[0003] The uplink coverage of a 5G network is a major bottleneck in network coverage. Since the difference in coverage capacity between the uplink channel and the downlink channel is dozens of dB, it is necessary to further strengthen the uplink channel. Dynamic waveform switching is a method for uplink enhancement. By scheduling the waveform of the PUSCH (Physical Uplink Shared Channel) in real time, it can be ensured that the PUSCH transmission has an appropriate rate and code rate, thereby improving the transmission performance of the PUSCH.

[0036] The technical solutions in the embodiments of this disclosure are described clearly and completely with reference to the drawings in the embodiments of this disclosure, and it is clear that the embodiments described are only some of the embodiments of this disclosure, and not all of the embodiments of this disclosure. The description of at least one exemplary embodiment below is essentially illustrative and is not intended to limit this disclosure, its application, or use. All other embodiments that a person skilled in the art can derive without creative effort from the embodiments disclosed herein are included within the scope of this disclosure.

[0037] The relative arrangements, numerical representations, and numerical values ​​of the components and steps described in these embodiments do not limit the scope of this disclosure unless otherwise specified.

[0038] On the other hand, it should be understood that the dimensions of each part shown in the drawings are not depicted in actual proportions, for the sake of explanatory purposes.

[0039] Techniques, methods, and devices known to those skilled in the art are not discussed in detail, but are intended to be part of this specification where appropriate.

[0040] In all examples shown and discussed herein, specific values ​​should be interpreted as illustrative, not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] In the following diagrams, the same reference number and letters refer to the same item; therefore, once an item is defined in one diagram, it does not need to be discussed further in subsequent diagrams.

[0042] Through their research, the inventors discovered that waveform switching can be represented by 1 bit of information or by multiplexing existing instruction fields, which may seem simple and crude but actually has a significant impact. One of the technical problems is that because the waveforms before and after switching are different, the power backoff is different, so the network needs to know the transmission power of the pusher in real time; otherwise, switching may be scheduled according to incorrect information, which can affect performance.

[0043] Taking into consideration at least one of the technical problems described above, this disclosure provides an auxiliary information reporting method and system, a terminal, and a computer-readable storage medium that enable the terminal to report terminal auxiliary information in real time. This disclosure is illustrated by the following specific embodiments.

[0044] Figure 1 is a schematic diagram of several embodiments of the auxiliary information reporting method according to the present disclosure. Preferably, this embodiment can be performed by a terminal of the present disclosure, which may be a UE (User Equipment). The method includes step 100.

[0045] In step 100, based on MAC-CE (Medium Access Control-Control Element), AI (Assistant Information) is reported to the network device (network-side device). This Assistant Information is used as reference information for the network device to perform uplink waveform switching and includes power-related information.

[0046] In some embodiments of this disclosure, the auxiliary information is waveform switching auxiliary information.

[0047] In some embodiments of this disclosure, the auxiliary information is dynamic waveform switching auxiliary information.

[0048] In some embodiments of the present disclosure, step 100 may include reporting auxiliary information based on MAC-CE to trigger a waveform switching operation on the network side.

[0049] In other embodiments of the present disclosure, step 100 may include triggering the reporting of auxiliary information based on MAC-CE after the waveform switching operation.

[0050] In some embodiments of this disclosure, dynamic waveform switching is supported in networks in related technologies, specifically in random access procedures where the waveform of MSG3 (message 3 of the random access procedure) scheduled via DCI (Downlink Control Information) 0-0 may differ from the waveform of a normal PUSCH scheduled via DCI 0-1, thus requiring waveform switching. However, the above waveform switching belongs to waveform switching performed by scheduling different DCIs, which has a long time delay, a very fixed mechanism, and cannot meet the requirements of a dynamic and flexible waveform switching mechanism. Therefore, in this disclosure, a different mechanism is designed to support dynamic waveform switching.

[0051] Through their research, the inventors have discovered that in waveform switching processes, the Discrete Fourier Transform (DFT) only supports continuous frequency domain resource allocation for a single stream and is limited by the DFT implementation technique, requiring the allocation of frequency domain resource blocks in multiples of 2, 3, and 5. Therefore, in actual switching, when switching from a Cyclic Prefix (CP) waveform to a DFT waveform, various problems can occur, such as mismatches in resource allocation types and improper power transmission. While some of these problems can be solved by reasonable configuration and scheduling, the network side cannot perform real-time measurement and modification of related issues such as power values. Therefore, in this disclosure, the UE needs to provide the network equipment with corresponding auxiliary information in advance to help the network equipment schedule uplink dynamic waveform switching with the correct transmission parameters, in addition to adding switching instructions.

[0052] In some embodiments of this disclosure, UE auxiliary information may include FDRA (Frequency Domain Resource Assignment) type, MCS (Modulation and Coding Scheme) level information, power-related information such as PHR (Power Headroom Report) and PCmax (Maximum Transmission Power), and combinations thereof.

[0053] In some embodiments of this disclosure, the auxiliary information includes at least one of MCS level information, FDRA type, or power-related information.

[0054] In some embodiments of this disclosure, power-related information includes at least one of power headroom report (PHR) information, PCmax, power fluctuations, power difference, power value, or power compression factor, where power difference is the power difference between the auxiliary information and the PHR.

[0055] In some embodiments of the present disclosure, the power difference may be the difference in PHR relative to auxiliary information, or the power difference between two different waveforms. Alternatively, a fixed power difference (offset) may be determined from one waveform, and the power values ​​of the other waveform may be considered as the sum or difference between the waveform and the fixed power difference.

[0056] In some embodiments of this disclosure, the auxiliary information includes at least one of the actual PHR information after waveform switching or reference PHR information.

[0057] In some embodiments of this disclosure, the auxiliary information includes at least one of the actual PHR information before waveform switching or reference PHR information.

[0058] For example, if a PHR does not need to be reported before waveform switching, but the base station needs to decide on waveform switching, the terminal is triggered to report one piece of auxiliary information. In this case, the auxiliary information reported by the terminal includes at least one of the following: the actual PHR of the current waveform or the reference PHR of the waveform being switched.

[0059] In some embodiments of this disclosure, the auxiliary information is reference PHR information of a waveform different from the current waveform after switching.

[0060] Since real-time power information can only be reported in real time by the UE, this disclosure enables the UE to report auxiliary information, which includes PHR, PCmax, or the power difference between the auxiliary information and PHR, so that the network can correctly schedule the PUSCH waveform, guarantee uplink transmission performance, and improve network coverage capabilities.

[0061] Through their research, the inventors have discovered that UE's uplink dynamic waveform switching allows network equipment to perform uplink transmission by using the optimal waveform, thereby improving the uplink transmission rate in real time when network quality is good, and ensuring better transmission quality when network quality is poor. Therefore, the feasibility of this technology has been widely discussed in the R18 release. Directing dynamic waveform switching is a simpler function, such as adding 1 bit of directive information. However, the switching process from DFT to CP, or from CP to DFT, requires changing the MCS, changing the FDRA type, different power control for the two waveforms, and knowing the power difference before and after switching. Therefore, in this disclosure, the UE reports several auxiliary pieces of information as reference information for network equipment to schedule dynamic waveform switching, enabling the most rational switching directives.

[0062] Waveform switching processing may involve reporting of PHR and auxiliary information. This auxiliary information may include PHR, PCmax, and power difference, and is generally waveform power reference information after switching.

[0063] In some embodiments of this disclosure, the auxiliary information is generally power reference information of a different waveform than the current waveform before or after waveform switching.

[0064] In other embodiments of this disclosure, the auxiliary information may be the waveform state of the current waveform before or after waveform switching.

[0065] To provide a rational reporting mode and structure for supplementary information and to distinguish it from PHR reporting to avoid confusion, this disclosure states that both supplementary information and PHR use the same trigger mechanism, but their reporting formats are different.

[0066] Therefore, this disclosure designs a trigger process and reporting format for a MAC-CE-based trigger mechanism different from PHR, ensuring reasonable and accurate reporting of supplementary information and improving the reporting process so as not to interfere with the PHR reporting process.

[0067] This disclosure is illustrated below by specific embodiments.

[0068] Figure 2 is a schematic diagram of another embodiment of the auxiliary information reporting method according to the present disclosure. Preferably, this embodiment can be performed by the terminal of the present disclosure. The method (for example, the steps in the embodiment of Figure 1) may include at least one of steps 110 and 120.

[0069] In step 110, the auxiliary information trigger mechanism is determined.

[0070] In some embodiments of the present disclosure, the auxiliary information trigger mechanism may include at least one of a power headroom report (PHR) information trigger mechanism, a first auxiliary information trigger mechanism, or an independent auxiliary information trigger mechanism.

[0071] In step 120, auxiliary information is reported based on MAC-CE according to the auxiliary information trigger mechanism.

[0072] In some embodiments of this disclosure, step 120 may include at least one of steps 121 to 123.

[0073] In step 121, the auxiliary information is triggered simultaneously with the PHR; that is, the auxiliary information is triggered simultaneously with the PHR by the UE.

[0074] In some embodiments of the present disclosure, step 121 may include simultaneously triggering the reporting of auxiliary information and power headroom report (PHR) information according to a PHR information trigger mechanism.

[0075] In some embodiments of this disclosure, in step 121, the auxiliary information is triggered simultaneously because the PHR legacy trigger event is used.

[0076] In some embodiments of this disclosure, the PHR is triggered primarily by at least one of the following events:

[0077] 1. If there is an uplink resource on the MAC for a new transmission, the Phr-ProhibitTimer times out or has timed out, and the change in path loss of at least one active cell of the MAC entry is greater than the PHR-Tx-PowerFactorChange compared to the path loss of at least one active cell when the previous PHR was transmitted on the MAC.

[0078] In some embodiments of this disclosure, the parameter PHR-Tx-PowerFactorChange is used as path loss reference information. Evaluating the path loss change of a cell involves comparing the following two path loss values, namely the path loss measured at the current time under the current path loss reference configuration and the path loss measured under the path loss reference configuration during a previous PHR transmission, without considering changes in the path loss reference information between two time points.

[0079] 2. The phr-PeriodicTimer times out, triggering a periodic PHR.

[0080] 3. PHR functions that do not include deactivated configurations are configured or reconfigured at a higher level.

[0081] 4. Activation of a Serving Cell (SCell) is configured via the uplink in any one MAC entity.

[0082] 5. One SCG is activated.

[0083] 6. Add PScell ​​(if SCG is not deactivated).

[0084] 7. If there is an uplink resource for a new transmission on the MAC, the Phr-ProhibitTimer times out or has timed out, and for any MAC, for an activated serving cell configured on the uplink, the PHR is triggered if the following conditions are met: namely, the activated serving cell has an uplink resource for transmission or PUCCH transmission, and there is a PUSCH or PUCCH transmission in the MAC entry, and the change in the cell's power backoff is greater than the power backoff value reported by the PHR, compared to the power backoff value.

[0085] 8. An uplink SCell is set to any one MAC entry, which activates the BWP's switching process from sleep state to non-sleep state.

[0086] 9. mpe-Reporting-FR2 is set, but mpe-ProhibitTimer is not started. After the last PHR transmission of the MAC-CE entry, the measured P-MPR value to satisfy the FR2 MPE requirement is greater than or equal to the MPE-Threshold of at least one activated FR2 serving cell. Or, after the last PHR transmission, the measured P-MPR value to satisfy the MPE requirement is greater than or equal to the mpe-Threshold, so the entry changes a value Db greater than phr-Tx-PowerFactorChange and acts on at least one activated FR2 serving cell.

[0087] In step 122, some mechanisms use PHR triggers (Legacy Trigger Events), while others use UE Independent Auxiliary Information Triggers (New Trigger Events).

[0088] In some embodiments of the present disclosure, step 122 may include triggering the reporting of auxiliary information according to a first auxiliary information trigger mechanism, the first auxiliary information trigger mechanism including a power headroom reporting (PHR) information trigger mechanism and an independent auxiliary information trigger mechanism, the independent auxiliary information trigger mechanism and the PHR information trigger mechanism being independent of each other. For example, if the PHR information trigger mechanism includes m trigger conditions and the independent auxiliary information trigger mechanism includes n trigger conditions, then the first auxiliary information trigger mechanism includes m+n trigger conditions, where m and n are natural numbers greater than 0.

[0089] In some embodiments of this disclosure, part of the auxiliary information in step 122 is a legacy PHR trigger mechanism, and part of the auxiliary information in step 122 allows for the independent setting of the trigger conditions (mechanism) of the auxiliary information.

[0090] In some embodiments of this disclosure, the trigger for auxiliary information in the UE follows the trigger for the PHR.

[0091] In some embodiments of the present disclosure, the waveform is changed and auxiliary information is reported so that the base station provides power information for a different waveform in order to perform switching reference and power management. Generally, one PHR is reported after waveform switching, and the auxiliary information needs to have a time between the PHR trigger time and the DCI that instructs to report the auxiliary information PUSCH as reference information. In a multi-carrier scenario, it is determined whether the auxiliary information for a different carrier reports the actual PHR or the reference PHR depending on whether the trigger times of the two pieces of auxiliary information are within the interval.

[0092] In some embodiments of this disclosure, auxiliary information of the UE is triggered before the triggering of the PHR. For example, before waveform switching, the auxiliary information is reported so that the base station can refer to the power state of a different waveform than the current waveform.

[0093] In step 123, a completely new UE auxiliary information trigger condition (a new trigger event) is used, which is unrelated to the PHR trigger mechanism.

[0094] In some embodiments of the present disclosure, step 123 may include triggering the reporting of auxiliary information according to an independent auxiliary information trigger mechanism, wherein the independent auxiliary information trigger mechanism and the power headroom reporting (PHR) information trigger mechanism are independent of each other.

[0095] In some embodiments of the present disclosure, an independent auxiliary information trigger mechanism may include being triggered by waveform switching instruction information or by a waveform switching operation.

[0096] In some embodiments of the present disclosure, an independent auxiliary information trigger mechanism may include indicating an auxiliary information reporting trigger by DCI and / or reported content and / or reported type and / or reported sequence or priority, and indicating the remainder in a pre-configured or predefined manner.

[0097] In some embodiments of this disclosure, the independent auxiliary information trigger mechanism may include an explicit trigger or an implicit trigger.

[0098] In some embodiments of the present disclosure, an explicit trigger may include at least one of the following steps: triggering the reporting of auxiliary information by adding an instruction field to the DCI; triggering the reporting of auxiliary information by multiplexing an existing instruction field on the DCI; or adding a new format for the instruction.

[0099] In some embodiments of the present disclosure, an implicit trigger may include triggering the reporting of auxiliary information by a combined instruction consisting of one or a combination of the following steps: the MCS reaching a first threshold, issuing a waveform switching instruction, the FDRA indicating type 1, the TPMI (Transmitted Precoding Matrix Indicator) rank (channel rank) number reaching a second threshold, and the TPC (Transmit Power Control) reaching a third threshold.

[0100] This disclosure provides a method for reporting waveform switching aid information based on a media control access unit. This disclosure belongs to the field of wireless communication and terminals. This disclosure may be used to help a network perform better dynamic waveform switching.

[0101] In some embodiments of the present disclosure, the step of reporting auxiliary information based on a media access control-control element MAC-CE (for example, step 100 in the embodiment of Figure 1, or step 120 in the embodiment of Figure 2) may include reporting auxiliary information by employing a MAC-CE entry, which is either a single-entry MAC-CE or a multi-entry MAC-CE.

[0102] In some embodiments of the present disclosure, the MAC-CE entry is at least one of a first MAC-CE entry, a second MAC-CE entry, and a third MAC-CE entry, wherein the first MAC-CE entry is a legacy MAC-CE entry of related technology, and the second and third MAC-CE entries are new MAC-CE entries.

[0103] Three MAC-CE entries are described below with reference to specific embodiments.

[0104] First MAC-CE entry:

[0105] In some embodiments of the present disclosure, reporting auxiliary information by employing a MAC-CE entry may include reporting auxiliary information by employing a first MAC-CE entry, the first MAC-CE entry being a MAC-CE entry of the relevant technology, and the first MAC-CE entry is suitable for a single-entry or multi-entry MAC-CE.

[0106] In some embodiments of the present disclosure, reporting auxiliary information by employing a first MAC-CE entry includes modifying a predetermined field of the first MAC-CE entry, using the predetermined field to indicate a first MAC-CE entry for reporting auxiliary information or PHR information, and reporting auxiliary information by using the first MAC-CE entry.

[0107] In some embodiments of this disclosure, the predetermined field is a reserved field R or LCID (Logical Channel Identification).

[0108] In some embodiments of this disclosure, the predetermined field is a reserved field R or LCID and may be applicable to single-entry or multi-entry MAC-CEs.

[0109] Figure 3 is a schematic diagram of several embodiments of the first MAC-CE structure of the supplementary information provided herein. Figure 3 shows a single entry as an example. As shown in Figure 3, the reserved field R may be modified to indicate whether the MAC-CE of the related technology is used for PHR or for reporting based on supplementary information. In the embodiment of Figure 3, the reserved field R is used to add instructions for PHR reporting or supplementary information reporting.

[0110] As shown in Figure 3, in some embodiments of the present disclosure, field R may be defined as an indicator field for distinguishing auxiliary information from PHR information. Field R being 0 means that field PH in MAC-CE is used for PHR indication (i.e., for the waveform before switching), and field R being 1 means that field PH in MAC-CE is used for auxiliary information indication (i.e., for the waveform after switching).

[0111] Figure 4 is a diagram of MAC-CE entries that define a new LCID table for distinguishing auxiliary information in some embodiments of the present disclosure. As shown in Figure 4, in UE auxiliary information reporting triggered based on MAC-CE, if a prior art MAC-CE structure is used, the LCID of the MAC-CE may be modified to indicate whether the existing MAC-CE is used for PHR or for reporting based on auxiliary information.

[0112] As shown in Figure 4, in some embodiments of this disclosure, a new LCID (a new MAC subheader having an LCID) is used to specifically report auxiliary information.

[0113] As shown in Figure 4, in some embodiments of the present disclosure, 37 and 38 of the LCID table are defined as auxiliary information LCIDs, and a MAC-CE using two LCIDs is considered as auxiliary information MAC-CE.

[0114] Second MAC-CE entry:

[0115] In some embodiments of this disclosure, reporting auxiliary information by employing a MAC-CE entry may include reporting auxiliary information by employing a second MAC-CE entry, the second MAC-CE entry being a new MAC-CE entry, and the second MAC-CE entry is applicable to single-entry or multi-entry MAC-CEs.

[0116] In some embodiments of this disclosure, single-entry and multiple-entry distinguish only whether or not there are multiple carriers (cells) and not the ability to carry auxiliary information. In the case of single-entry, field R is not used to indicate the actual PHR or reference PHR, and a line is added immediately below the MAC-CE entry, which is a report of auxiliary information.

[0117] Therefore, the methods employed in this disclosure for reporting auxiliary information in the first MAC-CE entry, the second MAC-CE entry, or the third MAC-CE entry are applicable to single-entry MAC-CE or multi-entry MAC-CE.

[0118] In some embodiments of the present disclosure, reporting auxiliary information by employing a second MAC-CE entry includes employing a new MAC-CE entry as a second MAC-CE entry by adding an entry size and expanding the indicator field based on a first MAC-CE entry, and reporting auxiliary information by employing the second MAC-CE entry.

[0119] In some embodiments of this disclosure, the step of adding an entry size may include adding an auxiliary information entry.

[0120] In some embodiments of the present disclosure, the step of extending an indicator field may include extending a first indicator field, which is used to indicate whether or not there is an auxiliary information report in each serving cell.

[0121] In some embodiments of the present disclosure, the step of extending an indicator field may include adding a second indicator field, the second indicator field being used to indicate the reporting of reference auxiliary information or actual auxiliary information.

[0122] In some embodiments of the present disclosure, as shown in Figures 5 and 6, the step of extending a first indicator field may include extending an indicator field Ci as a first indicator field, the indicator field Ci being used to indicate whether each serving cell reports auxiliary information and PHR information simultaneously.

[0123] Figure 5 is a schematic diagram of several embodiments of the second MAC-CE structure of the auxiliary information according to this disclosure. As shown in Figure 5, when the new MAC-CE structure is used in a UE auxiliary information report triggered based on MAC-CE, the indication field may be extended or added, a new assist information MAC-CE entry may be added, the auxiliary information may be reported using the same Ci indication scheme as in the PHR report, and Va may be used to indicate the reporting of reference assistant information and actual assistant information.

[0124] Figure 6 is a schematic diagram of another embodiment of the second MAC-CE structure of auxiliary information according to this disclosure. As shown in Figures 5 and 6, an auxiliary information field and a field indicating whether the auxiliary information is reference or actual are added to the original MAC-CE entry, where field R is a reserved bit. The auxiliary information may be placed after the power information for each carrier (as shown in Figure 5) or all auxiliary information structures may be placed afterwards (as shown in Figure 6), and both expressions in the embodiments of Figures 5 and 6 show auxiliary information reported by Ci for different carriers. In the embodiments of Figures 5 and 6, the same carrier indicator Ci is used.

[0125] As shown in Figures 7 and 8, in some embodiments of the present disclosure, the step of extending the first indicator field may include adding an indicator field as the first indicator field, the newly added indicator field being used to indicate whether each serving cell reports auxiliary information.

[0126] In some embodiments of this disclosure, the newly added instruction field may be the instruction field Cai.

[0127] Figure 7 is a schematic diagram of yet another embodiment of the second MAC-CE structure of auxiliary information according to this disclosure. Figure 8 is a schematic diagram of yet another embodiment of the second MAC-CE structure of auxiliary information according to this disclosure. As shown in Figures 7 and 8, when a new MAC-CE structure is used in a UE auxiliary information report triggered based on MAC-CE, the indicator fields can be expanded, auxiliary information entries can be added, a different Cai from the PHR can be used specifically to report the auxiliary information, and Va can be used to indicate the reference and the actual auxiliary information report. In the embodiments of Figures 7 and 8, the respective carrier indicators are used, with the PHR report indicated by Ci and the auxiliary information report indicated by Cai.

[0128] In some embodiments of this disclosure, as shown in Figures 7 and 8, an auxiliary information field and a field indicating whether the auxiliary information is reference or actual are added to the original MAC-CE entry, where field R is a reserved bit. The auxiliary information may be placed after the power information for each carrier (as shown in Figure 7), or all auxiliary information structures may be placed afterwards (as shown in Figure 8). Both expressions represent auxiliary information reported by different carriers, different from the PHR.

[0129] In some embodiments of the present disclosure, the step of adding entry size may include placing auxiliary information for each serving cell after the carrier power information for each serving cell, as shown in Figures 5 and 7, or placing all auxiliary information structures after all carrier power information, as shown in Figures 6 and 8.

[0130] In some embodiments of the present disclosure, as shown in Figures 9 and 10, when the carrier waveform of each serving cell includes various waveforms, reporting auxiliary information by employing a second MAC-CE entry may include reporting auxiliary information for the various waveforms in a unified manner, or selecting and reporting auxiliary information for one of the various waveforms.

[0131] Figure 9 is a schematic diagram of yet another embodiment of the second MAC-CE structure of the auxiliary information according to this disclosure. Figure 10 is a schematic diagram of yet another embodiment of the second MAC-CE structure of the auxiliary information according to this disclosure. In one case, each carrier may have two RRC configuration waveforms, in which case the auxiliary information can be extended to the CP waveform of carrier 1 and the DFT waveform of carrier 1. The new MAC-CE structure (see Figures 9 and 10) is used to specifically report the auxiliary information, and the MAC-CE may include auxiliary information of different waveforms under multiple carriers, and a unified report may be made, or one of them may be selected for reporting.

[0132] In some embodiments of this disclosure, as shown in Figures 9 and 10, auxiliary information indicators for different waveforms are added to the original MAC-CE entry, and field R may still be reserved so that auxiliary information for all waveforms can be reported as a whole. Field R may also be used to indicate whether or not to report auxiliary information for DFT waveforms or CP waveforms, so a 1-bit indicator information field is required.

[0133] Although the embodiments of Figures 9 and 10 of this disclosure are described by simply taking the structure of the embodiment of Figure 8 of this disclosure as an example, it is also conceivable that the embodiments of Figures 9 and 10 of this disclosure can be implemented based on the structure of the embodiment of Figure 6 of this disclosure, that is, the two methods described above can be designed without independently using the auxiliary information carrier directive of Cai.

[0134] In some embodiments of the present disclosure, the step of placing auxiliary information for each serving cell after the carrier power information for each serving cell includes (as in the embodiments of Figures 5 and 7) placing auxiliary information for various waveforms within each serving cell after the carrier power information for each serving cell.

[0135] In some embodiments of the present disclosure, the step of placing all auxiliary information after all carrier power information includes, as shown in the embodiment of Figure 9, unifying the auxiliary information for various waveforms within all serving cells according to serving cell identification information and then ordering the auxiliary information, or, as shown in the embodiment of Figure 10, unifying the auxiliary information for various waveforms within all serving cells according to waveform type and then ordering the auxiliary information.

[0139] Figure 11 is a schematic diagram of several embodiments of the third MAC-CE structure of auxiliary information as disclosed herein. As shown in Figure 11, a completely new MAC-CE entry is used solely to report auxiliary information, without reporting information such as PHR and PCmax of the waveform before switching.

[0140] As shown in Figure 11, in some embodiments of this disclosure, the MAC-CE entry is used solely to report UE auxiliary information, canceling information such as PCmax, PHR, which was originally reported by PHR.

[0141] This disclosure provides a reporting mechanism for UE supplementary information, including determining the reporting format and refining the reporting content.

[0142] The embodiments described above in this disclosure provide a trigger mode for reporting UE supplementary information based on MAC-CE, an implementation format for reporting UE supplementary information based on MAC-CE, and a specific implementation process for reporting and refining UE supplementary information based on MAC-CE.

[0143] The embodiments described above of this disclosure determine the trigger mode for auxiliary information, design corresponding reporting formats and methods, refine the specific implementation process for reporting auxiliary information, and effectively solve the problem that auxiliary information and PHR cannot be distinguished under the same reporting category.

[0144] According to embodiments of the present disclosure, network equipment can determine whether or not to perform dynamic waveform switching according to reference information, and can improve the uplink transmission rate in real time when network quality is good, or ensure better transmission quality when network quality is poor, thereby enabling the most rational waveform switching instruction and improving network coverage capability.

[0174] Through their research, the inventors have discovered that when uplink dynamic waveform switching is performed, it may involve MCS changes, requiring a change in FDRA type, resulting in different power control associated with the two waveforms, and requiring knowledge of the power difference before and after switching. Therefore, the embodiments described above in this disclosure can help network equipment perform dynamic switching more effectively and ensure better network coverage capabilities by reporting effective uplink auxiliary information.

[0175] Through their research, the inventors discovered that uplink dynamic waveform switching auxiliary information can include PHR reporting and auxiliary information reporting, where PHR is generally a report of waveform power before switching, and auxiliary information is generally waveform power reference information after switching. To avoid confusion, auxiliary information needs to be given a reasonable reporting mode and structure, and to distinguish it from PHR reporting, both auxiliary information and PHR need to use different reporting formats, even though they use the same trigger mechanism. Therefore, the above embodiments of this disclosure can be designed with corresponding trigger processes and reporting formats to ensure reasonable and accurate reporting of auxiliary information and to avoid mutual interference with the PHR reporting process.
