[0036] The technical solutions in the embodiments of the present disclosure are clearly and completely described with reference to the drawings in the embodiments of the present disclosure, and it is clear that the described embodiments are only some embodiments of the present disclosure, not all embodiments of the present disclosure. The following description of at least one exemplary embodiment is merely exemplary in nature and is not intended to limit the present disclosure, its application, or uses. All other embodiments that a person skilled in the art can derive from the embodiments disclosed herein without creative efforts shall fall within the protection scope of the present disclosure.

[0037] The relative arrangement of parts and steps, numerical expressions and values ​​described in these embodiments do not limit the scope of the present disclosure unless otherwise specified.

[0038] However, it should be understood that the sizes of the parts shown in the drawings are not drawn to actual proportions for the sake of convenience.

[0039] Techniques, methods, and devices known to those skilled in the relevant arts may not be discussed in detail, but are intended to be incorporated into this specification where appropriate.

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

[0041] It should be noted that in the following figures, the same reference numbers and letters refer to the same items, so that once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0042] Through research, the inventors have found that waveform switching can be indicated by one bit of information or multiplexing of existing indication fields, which seems simple and crude, but actually has a great impact. One of the technical problems is that different waveforms before and after switching have different power backoffs, so the network needs to know the transmission power of PUSCH in real time, otherwise switching may be scheduled according to incorrect information, which may affect performance.

[0043] In consideration of at least one of the above technical problems, the present disclosure provides an auxiliary information reporting method and system, a terminal, and a computer-readable storage medium, which enable a terminal to report terminal auxiliary information in real time. The present disclosure is exemplified by the following specific embodiments.

[0044] 1 is a schematic diagram of some embodiments of an auxiliary information reporting method according to the present disclosure. Preferably, the embodiments can be performed by a terminal of the present disclosure, and the terminal 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 a network device (network side device), and the AI ​​is used as reference information for the network device to perform uplink waveform switching, and the AI ​​includes power-related information.

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

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

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

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

[0050] In some embodiments of the present disclosure, regarding dynamic waveform switching, waveform switching is already supported in networks in the related art. That is, in a random access procedure, the waveform of MSG3 (Message 3 of Random Access Procedure) scheduled via DCI (Downlink Control Information) 0-0 may be different from the waveform of a normal PUSCH scheduled via DCI 0-1, and therefore waveform switching is performed. However, the above waveform switching belongs to waveform switching performed by scheduling different DCI, which has a long time delay and a very fixed mechanism, and cannot meet the requirements of a dynamic and flexible waveform switching mechanism. Therefore, in the present disclosure, another mechanism is designed to support dynamic waveform switching.

[0051] Through research, the inventors have found that in the waveform switching process, DFT (Discrete Fourier Transform) only supports single-stream continuous frequency-domain resource allocation and is limited by the DFT implementation technology, requiring allocation of frequency-domain resource blocks in multiples of two, three, or five. Therefore, in actual switching, when switching from a cyclic prefix (CP) waveform to a DFT waveform, various problems, such as resource allocation type mismatch and inappropriate power transmission, may occur. While some of the above problems can be solved through 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, in addition to adding a switching instruction, the UE needs to provide corresponding auxiliary information to the network equipment in advance to assist the network equipment in scheduling uplink dynamic waveform switching with the correct transmission parameters.

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

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

[0054] In some embodiments of the present disclosure, the power-related information includes at least one of power headroom report (PHR) information, PCmax, power variation, power difference, power value, or power compression factor, and the 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 the auxiliary information, or may be the power difference between two different waveforms; alternatively, a fixed power difference (offset) can be determined from one waveform, and the power value of the other waveform can be taken into account as the sum or difference between the waveform and the fixed power difference.

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

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

[0058] For example, if there is no need to report a PHR 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 which case the auxiliary information reported by the terminal includes at least one of the actual PHR of the current waveform or the reference PHR of the waveform to be switched to.

[0059] In some embodiments of the present 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 by the UE in real time, in order to enable network equipment to grasp status information such as UE power in real time, the present disclosure enables the UE to report auxiliary information, where the auxiliary information includes PHR, PCmax, or the power difference between the auxiliary information and PHR, so that the network can correctly schedule the PUSCH waveform, ensure uplink transmission performance, and improve network coverage capability.

[0061] Through research, the inventors discovered that UE 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 improves and better ensuring transmission quality when network quality deteriorates. Therefore, the feasibility of this technology has been widely discussed in the R18 release. The dynamic waveform switching instruction is a simple function, such as adding one bit of instruction information. However, the process of switching from DFT to CP or from CP to DFT requires changing the MCS, changing the FDRA type, and the power control of the two waveforms is different, so the power difference before and after switching must be known. Therefore, in this disclosure, the UE reports some auxiliary information as reference information for the network equipment to schedule dynamic waveform switching and make the most reasonable switching instruction.

[0062] The waveform switching process may involve reporting PHR and auxiliary information, which may include information such as PHR, PCmax, and power difference, typically the post-switching waveform power reference.

[0063] In some embodiments of the present disclosure, the auxiliary information is typically power reference information of another waveform different from the current waveform before or after waveform switching.

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

[0065] To provide a reasonable reporting mode and structure for auxiliary information and distinguish it from PHR reporting to avoid confusion, in this disclosure, both auxiliary information and PHR use the same trigger mechanism but have different reporting formats.

[0066] Therefore, this disclosure designs a trigger process and reporting format for the MAC-CE-based trigger mechanism that is different from that of PHR, and improves the reporting process to ensure reasonable and accurate reporting of auxiliary information and avoid mutual impact on the PHR reporting process.

[0067] The present disclosure is illustrated below by specific embodiments.

[0068] 2 is a schematic diagram of another embodiment of an auxiliary information reporting method according to the present disclosure. Preferably, this embodiment can be performed by the terminal of the present disclosure. The method (e.g., the steps in the embodiment of FIG. 1) may include at least one of step 110 and step 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 reporting (PHR) information trigger mechanism, a first auxiliary information trigger mechanism, or an independent auxiliary information trigger mechanism.

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

[0072] In some embodiments of the present 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 reporting of the auxiliary information and power headroom reporting (PHR) information according to a PHR information triggering mechanism.

[0075] In some embodiments of the present disclosure, in step 121, the auxiliary information uses a legacy trigger event of the PHR, so that the auxiliary information is triggered simultaneously.

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

[0077] 1. If there are uplink resources available for a new transmission on the MAC, the Phr-ProhibitTimer times out or has timed out and the change in path loss of at least one active cell for the MAC entry is greater than 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 the present disclosure, the parameter PHR-Tx-PowerFactorChange is used as the path loss reference. The evaluation of the path loss change of a cell is to compare 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 at the time of the previous PHR transmission, without taking into account the change in the path loss reference information between the two times.

[0079] 2.phr-PeriodicTimer times out and triggers a periodic PHR.

[0080] 3. A PHR feature that does not have a deactivated configuration is configured or reconfigured at a higher layer.

[0081] 4. Serving cell (SCell) activation is configured in the uplink in one of the MAC entities.

[0082] 5. One SCG is activated.

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

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

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

[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 that satisfies the FR2 MPE requirement is greater than or equal to the MPE-Threshold for at least one activated FR2 serving cell. Or, since the last PHR transmission, the measured P-MPR value that satisfies the MPE requirement is greater than or equal to the mpe-Threshold, so the entry changes Db by a value greater than phr-Tx-PowerFactorChange and acts on at least one activated FR2 serving cell.

[0087] In step 122, some mechanisms use a PHR trigger (legacy trigger event) and some mechanisms use a UE independent auxiliary information trigger (new trigger event).

[0088] In some embodiments of the present disclosure, step 122 may include triggering reporting of the auxiliary information according to a first auxiliary information trigger mechanism, where the first auxiliary information trigger mechanism includes a power headroom reporting (PHR) information trigger mechanism and an independent auxiliary information trigger mechanism, and the independent auxiliary information trigger mechanism and the PHR information trigger mechanism are 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, 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 the present disclosure, some of the auxiliary information in step 122 may be a legacy PHR trigger mechanism, and some of the auxiliary information in step 122 may independently set the trigger conditions (mechanisms) of the auxiliary information.

[0090] In some embodiments of the present disclosure, the triggering of the UE's assistance information follows the triggering of the PHR.

[0091] In some embodiments of the present disclosure, the waveform is changed and the auxiliary information is reported to provide power information of another waveform for the base station to perform switching reference and power management. Therefore, generally, one PHR is reported after waveform switching, and the auxiliary information needs to take time between the PHR trigger time and the DCI instructing to report the auxiliary information PUSCH as reference information. In a multi-carrier scenario, depending on whether the trigger times of the two auxiliary information are within the interval, it is determined whether the auxiliary information of different carriers reports the actual PHR or the reference PHR.

[0092] In some embodiments of the present disclosure, the UE's aiding information is triggered before the PHR is triggered, for example, before waveform switching, the aiding information is reported so that the base station can refer to the power status of another waveform different from the current waveform.

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

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

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

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

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

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

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

[0100] The present disclosure provides a method for reporting waveform switching assistance information based on a medium control access unit. The present disclosure belongs to the field of wireless communication and terminals. The present disclosure can be used to assist a network in performing better dynamic waveform switching.

[0101] In some embodiments of the present disclosure, the step of reporting the auxiliary information based on a medium access control-control element MAC-CE (e.g., step 100 in the embodiment of FIG. 1 or step 120 in the embodiment of FIG. 2) may include reporting the auxiliary information by employing a MAC-CE entry, where the MAC-CE entry is a single-entry MAC-CE or a multiple-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, where the first MAC-CE entry is a legacy MAC-CE entry, and the second MAC-CE entry and the third MAC-CE entry 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 the auxiliary information by employing a MAC-CE entry may include reporting the auxiliary information by employing a first MAC-CE entry, where the first MAC-CE entry is a MAC-CE entry of the related art, and the first MAC-CE entry is suitable for a single-entry or a multiple-entry MAC-CE.

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

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

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

[0109] 3 is a schematic diagram of some embodiments of a first MAC-CE structure of the aiding information according to the present disclosure. FIG. 3 shows a single entry as an example. As shown in FIG. 3, the reserved field R can be modified to indicate whether the related art MAC-CE is used for PHR or for aiding information-based reporting. In the embodiment of FIG. 3, the reserved field R is used to add an indication of PHR reporting or aiding information reporting.

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

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

[0112] As shown in FIG. 4, in some embodiments of the present disclosure, a new LCID (a new MAC subheader with the LCID) is used to specifically report the auxiliary information.

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

[0114] Second MAC-CE entry:

[0115] In some embodiments of the present disclosure, reporting the auxiliary information by employing a MAC-CE entry may include reporting the auxiliary information by employing a second MAC-CE entry, where the second MAC-CE entry is a new MAC-CE entry, and the second MAC-CE entry may be applicable to a single-entry or multiple-entry MAC-CE.

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

[0117] Therefore, the method in the present disclosure in which the first MAC-CE entry, the second MAC-CE entry, or the third MAC-CE entry is adopted to report auxiliary information is applicable to a single-entry MAC-CE or a multi-entry MAC-CE.

[0118] In some embodiments of the present disclosure, reporting the assistance information by employing a second MAC-CE entry includes: adding an entry size and extending an indication field based on the first MAC-CE entry to employ the new MAC-CE entry as the second MAC-CE entry; and reporting the assistance information by employing the second MAC-CE entry.
