Description

Technical Field

[0001] This disclosure relates to the field of wireless communication, and in particular to an auxiliary information reporting method and system, a terminal, and a computer-readable storage medium. Background Technology

[0002] Uplink coverage is a major bottleneck in 5G networks, and since the coverage capabilities of the uplink channel differ from the downlink channel by tens of dB, further enhancement of the uplink channel is needed. Dynamic waveform switching is one method for uplink enhancement. By scheduling the waveform of the PUSCH (Physical Uplink Shared Channel) in real time, it ensures that the PUSCH is transmitted at a reasonable rate and bit rate, thereby improving the transmission performance of the PUSCH. Summary of the Invention

[0003] The inventors discovered through research that waveform switching can be indicated using 1 bit or by reusing existing indicator fields. While this seems simple and straightforward, the impact of switching is actually quite significant. One key aspect is that different waveforms before and after the switch cause different power backoffs. Therefore, the network needs to know the transmission power of the PUSCH in real time; otherwise, it may schedule switching based on incorrect information, affecting performance.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0074] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0075] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0076] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0077] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0078] This disclosure provides an auxiliary information reporting method and system, a terminal, and a computer-readable storage medium. The following specific embodiments illustrate this disclosure.

[0079] Figure 1 This is a schematic diagram of some embodiments of the auxiliary information reporting method of this disclosure. Preferably, this embodiment can be executed by the terminal of this disclosure, and the terminal can be a UE (User Equipment). The method includes step 100, wherein:

[0080] Step 100: Based on MAC-CE (Medium Access Control-Control Element), AI (Assistant Information) is reported to the network-side device. The auxiliary information is used as a reference for the network-side device to perform uplink waveform switching. The auxiliary information includes power-related information.

[0081] In some embodiments of this disclosure, the auxiliary information is waveform switching auxiliary information.

[0082] In some embodiments of this disclosure, the auxiliary information is dynamic waveform switching auxiliary information.

[0083] In some embodiments of this disclosure, step 100 may include: reporting auxiliary information based on MAC-CE to trigger waveform switching behavior on the network side.

[0084] In some other embodiments of this disclosure, step 100 may include: triggering MAC-CE-based auxiliary information reporting after the waveform switching behavior.

[0085] In some embodiments of this disclosure, dynamic waveform switching is a waveform switching mechanism already supported in related technology networks. Specifically, during random access, the waveform of MSG3 (the third message in the random access procedure) scheduled via DCI (Downlink Control Information) 0-0 can be different from the waveform of ordinary PUSCH scheduled via DCI 0-1, thus achieving a switching mechanism. However, the above-mentioned waveform switching is performed through different DCI scheduling, which has a long latency and a very fixed mechanism, failing to meet the requirements of a dynamic and flexible waveform switching mechanism. Therefore, this disclosure designs a separate mechanism to support dynamic waveform switching.

[0086] The inventors discovered through research that during waveform switching, because DFT (Discrete Fourier Transform) only supports single-stream, continuous frequency domain resource allocation and is limited by DFT implementation technology, requiring the allocation of frequency domain resource blocks in multiples of 2, 3, and 5, various problems may arise during actual switching, such as incompatible resource allocation types and inappropriate power transmission, once switching from CP (Cyclic Prefix) waveforms to DFT waveforms. While some of these problems can be resolved through proper configuration and scheduling, issues such as power values ​​cannot be measured and changed in real time by the network. Therefore, in addition to adding a handover indication, this disclosure requires the UE to provide corresponding auxiliary information to the network in advance to help the network schedule uplink dynamic waveform switching using the correct transmission parameters.

[0087] In some embodiments of this disclosure, UE auxiliary information may include FDRA (Frequency Domain Resource Assignment) type, MCS (Modulation and Coding Scheme) level information, and PHR (Power Headroom Report) and P related to power. CMAX (Maximum transmission power) and other related information and their combinations.

[0088] In some embodiments of this disclosure, the auxiliary information includes at least one of MCS level information, FDRA type, and power-related information.

[0089] In some embodiments of this disclosure, the power-related information includes power headroom reporting (PHR) information, P... CMAX The power is at least one of the following: power change, power difference, power value, and power compression factor, wherein the power difference is the power difference between the auxiliary information and the PHR.

[0090] In some embodiments of this disclosure, the power difference can be a difference between PHR and auxiliary information; or it can be a power difference between two different waveforms; or a fixed power difference (offset) can be determined based on a certain waveform, and the power value of the other waveform is considered to be the sum or difference of this waveform and the fixed power difference.

[0091] In some embodiments of this disclosure, the auxiliary information includes actual PHR information and / or virtual PHR information after waveform switching.

[0092] In some embodiments of this disclosure, the auxiliary information includes actual PHR information and / or virtual PHR information before waveform switching.

[0093] For example, if a PHR (Positioning Header) is not required before waveform switching, but the base station needs to make a waveform switching decision, the terminal will be triggered to report auxiliary information. In this case, the auxiliary information reported by the terminal includes the actual PHR of the current waveform and / or the virtual PHR of the waveform to be switched.

[0094] In some embodiments of this disclosure, the auxiliary information is virtual PHR information of a waveform that is different from the current waveform after switching.

[0095] Since real-time power information can only be reported by the UE in real time, this disclosure, in order to enable the network to grasp the UE's power and other status information in real time, requires the UE to report auxiliary information, including PHR and P... CMAX Alternatively, the power difference between auxiliary information and PHR can be used to enable the network to correctly schedule the waveform of PUSCH, ensuring uplink transmission performance and improving network coverage.

[0096] The inventors discovered through research and development that UE uplink dynamic waveform switching enables the network to use the optimal waveform for uplink transmission. This can improve uplink transmission rate in real time when network quality improves, or better guarantee transmission quality when network quality is poor. Therefore, its feasibility was widely discussed in Release 18. The indication of dynamic waveform switching is a relatively simple feature, such as adding a 1-bit indicator. However, the process of switching from DFT to CP or from CP to DFT may involve modifications to the MCS, changes to the FDRA type, and different power control for the two waveforms, requiring knowledge of the power difference before and after the switch. Therefore, in this disclosure, the UE reports some auxiliary information for the network to refer to when scheduling dynamic waveform switching, thereby making the most reasonable switching indication.

[0097] During waveform switching, PHR reporting and auxiliary information reporting are involved. Auxiliary information may include PHR, P... CMAX Information such as power difference is generally used as a reference for the waveform power after switching.

[0098] In some embodiments of this disclosure, the auxiliary information is generally a power reference of another waveform before or after waveform switching.

[0099] In other embodiments of this disclosure, the auxiliary information may also be the waveform status of the current waveform before or after waveform switching.

[0100] In order to provide a reasonable reporting method and structure for auxiliary information, and to distinguish it from PHR reporting to avoid confusion, in this disclosure, auxiliary information and PHR can use the same triggering mechanism but use different reporting formats.

[0101] Therefore, this disclosure designs a triggering process and reporting format that differs from PHR for the MAC-CE-based triggering mechanism, and refines the reporting process to ensure that auxiliary information is reported reasonably and correctly, and does not cause mutual interference to the PHR reporting process.

[0102] The present disclosure will now be described through specific embodiments.

[0103] Figure 2 The diagram illustrates some other embodiments of the auxiliary information reporting method of this disclosure. Preferably, this embodiment can be executed by the terminal of this disclosure. The method (e.g.) Figure 1 The steps in the embodiment may include at least one of steps 110 and 120, wherein:

[0104] Step 110: Determine the auxiliary information triggering mechanism.

[0105] In some embodiments of this disclosure, the auxiliary information triggering mechanism may include at least one of a power margin reporting PHR information triggering mechanism, a first auxiliary information triggering mechanism, and an auxiliary information individual triggering mechanism.

[0106] Step 120: According to the auxiliary information triggering mechanism, auxiliary information is reported based on MAC-CE.

[0107] In some embodiments of this disclosure, step 120 may include at least one of steps 121 to 123, wherein:

[0108] Step 121, triggered simultaneously with PHR, that is, UE auxiliary information is triggered at the same time as PHR triggering.

[0109] In some embodiments of this disclosure, step 121 may include: triggering the reporting of auxiliary information and PHR information simultaneously according to the PHR information reporting triggering mechanism based on the power margin.

[0110] In some embodiments of this disclosure, in step 121, the auxiliary information uses the same triggering method as the PHR (legacy trigger event), which is why it is triggered simultaneously.

[0111] In some embodiments of this disclosure, the triggering of the PHR is mainly achieved by the following events:

[0112] 1. When there are uplink resources available for new transmissions on a MAC, phr-ProhibitTimer has timed out or has already timed out, and if the path loss of at least one active cell for any MAC entity changes more than phr-Tx-PowerFactorChange compared to the path loss of that cell during the previous PHR transmission on this MAC.

[0113] In some embodiments of this disclosure, the phr-Tx-PowerFactorChange parameter is used as a path loss reference. The assessment of path loss changes for a cell is performed by comparing the following two path loss values, without considering changes in the path loss reference between the two times: the path loss measured at the current time under the current path loss reference configuration; and the path loss measured at the time of the previous PHR transmission under the path loss reference configuration at that time.

[0114] 2. phr-PeriodicTimer timeout triggers the period PHR.

[0115] 3. When the upper layer configures or reconfigures the PHR function, excluding deactivation configurations.

[0116] 4. Activation of the SCell cell configured for uplink in any MAC entity.

[0117] 5. An SCG has been activated.

[0118] 6. PScell ​​additions (unless SCG is deactivated).

[0119] 7. When a MAC entity has resources available for uplink transmission, and the phr-ProhibitTimer times out or has already timed out, for any serving cell with uplink configured and active on any MAC, a PHR is triggered if the following conditions are met: the 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 reported when the PHR was last reported when this MAC entity had PUSCH or PUCCH transmission is greater than phr-Tx-PowerFactorChange.

[0120] 8. When an uplink SCell is configured on any MAC entity, and its BWP activation handover process changes from sleep to non-sleep state.

[0121] 9. mpe-Reporting-FR2 is configured, but mpe-ProhibitTimer is not started. After the last PHR transmission of the MAC-CE entity, the measured P-MPR value used to satisfy the FR2 MPE requirements is equal to or greater than the mpe-Threshold of at least one active FR2 serving cell. Or, after the last PHR transmission, because the measured P-MPR value satisfying the MPE requirements is equal to or greater than the mpe-Threshold, this entity changes a Db value greater than phr-Tx-PowerFactorChange, effective for at least one active FR2 serving cell.

[0122] Step 122: Some mechanisms use PHR triggering (legacy trigger event), while others use UE auxiliary information to trigger separately (new trigger event).

[0123] In some embodiments of this disclosure, step 122 may include: triggering the reporting of auxiliary information according to a first auxiliary information triggering mechanism, wherein the first auxiliary information triggering mechanism includes a power headroom (PHR) information reporting triggering mechanism and an auxiliary information individual triggering mechanism, the auxiliary information individual triggering mechanism and the PHR information triggering mechanism being independent of each other. For example: if the power headroom (PHR) information reporting triggering mechanism includes m triggering conditions and the auxiliary information individual triggering mechanism includes n triggering conditions, then the first auxiliary information triggering mechanism includes m+n triggering conditions, where m and n are natural numbers greater than 0.

[0124] In some embodiments of this disclosure, some of the auxiliary information in step 122 follows the triggering mechanism of PHR, while some of the auxiliary information can have separate triggering conditions (mechanisms) set for the auxiliary information.

[0125] In some embodiments of this disclosure, the UE's assistance information is triggered after the PHR is triggered.

[0126] In some embodiments of this disclosure, a PHR is generally reported after waveform switching because the waveform has changed. The auxiliary information provides power information of another waveform for the base station to use as a reference for handover and power management. This auxiliary information needs to be based on the time between the PHR triggle time and the DCI indicating the reporting of auxiliary information PUSCH. In a multi-carrier scenario, the auxiliary information of different carriers is determined to report the actual PHR or the virtual PHR based on whether the trigger time of the two auxiliary information is within this range.

[0127] In some embodiments of this disclosure, the UE's auxiliary information is triggered before the PHR. For example, before waveform switching, auxiliary information is reported for the base station to reference the power status of another waveform.

[0128] Step 123, fully utilizes the new UE assistance information triggering condition (new trigger event), independent of the PHR triggering mechanism.

[0129] In some embodiments of this disclosure, step 123 may include: triggering the reporting of auxiliary information according to the auxiliary information separate triggering mechanism, wherein the auxiliary information separate triggering mechanism is independent of the PHR information triggering mechanism.

[0130] In some embodiments of this disclosure, the auxiliary information triggering mechanism may include: triggering via waveform switching indication information, or triggering via waveform switching behavior.

[0131] In some embodiments of this disclosure, the auxiliary information triggering mechanism may include: the reporting of auxiliary information is triggered by DCI and / or the reporting content and / or the reporting type and / or the reporting order or priority, and the remaining content is implemented in a pre-configured or pre-defined manner.

[0132] In some embodiments of this disclosure, the auxiliary information triggering mechanism may include: explicit triggering or implicit triggering.

[0133] In some embodiments of this disclosure, the display trigger may include at least one of the following steps: triggering auxiliary information reporting by adding a new indicator field on the DCI; triggering auxiliary information reporting by reusing an existing indicator field on the DCI; or adding a new format for indication.

[0134] In some embodiments of this disclosure, the implicit triggering may include: triggering auxiliary information reporting via a joint indication. This is achieved through one or a combination of the following: the MCS reaches a first threshold; a waveform switching indication is given; the FDRA indication is type 1; the rank of the TPMI (Transmitted Precoding Matrix Indicator) reaches a second threshold; or the TPC (Transmit Power Control) reaches a third threshold.

[0135] This disclosure provides a method for reporting waveform switching auxiliary information based on a media control access unit. This disclosure belongs to the field of wireless communication and terminals. This disclosure can be used to help networks perform dynamic waveform switching more effectively.

[0136] In some embodiments of this disclosure, the step of reporting auxiliary information based on the control element MAC-CE of the Media Access Control layer (e.g.) Figure 1 Step 100 of the embodiment or Figure 2 Step 120 of the embodiment may include: using a MAC-CE entity structure to report auxiliary information, wherein the MAC-CE entity structure is a single-entity MAC-CE or a multi-entity MAC-CE.

[0137] In some embodiments of this disclosure, the MAC-CE entity structure can be a first MAC-CE entity structure, a second MAC-CE entity structure, and a third MAC-CE entity structure, wherein the first MAC-CE entity structure is a legacy MAC-CE entry; and the second and third MAC-CE entity structures are new MAC-CE entry structures.

[0138] The following describes these three MAC-CE entity structures with specific examples.

[0139] First MAC-CE entity structure:

[0140] In some embodiments of this disclosure, the step of using a MAC-CE entity structure to report auxiliary information may include: using a first MAC-CE entity structure to report auxiliary information, wherein the first MAC-CE entity structure is a MAC-CE entity structure of the related technology, and the use of the first MAC-CE entity structure is applicable to single-entity or multi-entity MAC-CE.

[0141] In some embodiments of this disclosure, the step of using the first MAC-CE entity structure for auxiliary information reporting includes: modifying a predetermined field of the first MAC-CE entity structure; using the predetermined field to instruct the first MAC-CE entity structure to be used for reporting auxiliary information or PHR information; and using the first MAC-CE entity structure to report auxiliary information.

[0142] In some embodiments of this disclosure, the predetermined field is a reserved R field or LCID (Logical Channel Identification).

[0143] In some embodiments of this disclosure, the predetermined field is a reserved R field or LCID, which can be applied to single-entity or multi-entity MAC-CE.

[0144] Figure 3This is a schematic diagram of some embodiments of the first MAC-CE structure for supporting information of this disclosure. Figure 3 Let's take a single entity as an example. Figure 3 As shown, the reserved R field can be modified to indicate whether the MAC-CE of the relevant technology is used for PHR or based on auxiliary information reporting. Figure 3 The embodiment uses a reserved R field to add an indication of whether PHR reporting or auxiliary information reporting is performed.

[0145] In some embodiments of this disclosure, such as Figure 3 As shown, the R field can be defined as: the field for distinguishing between auxiliary information and PHR information. An R field of 0 means that the PH field in the MAC-CE is used for PHR indication (i.e., for the waveform before handover), and an R field of 1 means that the PH field in the MAC-CE is used for auxiliary information indication (i.e., for the waveform after handover).

[0146] Figure 4 This is a schematic diagram illustrating the definition of a new LCID table in some embodiments of this disclosure for distinguishing MAC-CE entities with auxiliary information. For example... Figure 4 As shown, in UE auxiliary information reporting triggered by MAC-CE, if the MAC-CE structure of related technologies is used, the LCID of the MAC-CE can be modified so that it can indicate whether the existing MAC-CE is used for PHR or for auxiliary information reporting.

[0147] In some embodiments of this disclosure, such as Figure 4 As shown, a new LCID (new MAC subheader with LCID) is used specifically for reporting auxiliary information.

[0148] In some embodiments of this disclosure, such as Figure 4 As shown, 37 and 38 are defined as LCIDs for auxiliary information. MAC-CEs using these two LCIDs are considered to be auxiliary information MAC-CEs.

[0149] Second MAC-CE entity structure:

[0150] In some embodiments of this disclosure, the step of using a MAC-CE entity structure to report auxiliary information may include: using a second MAC-CE entity structure to report auxiliary information, wherein the second MAC-CE entity structure is a new MAC-CE entity structure (new MAC-CE entry), and the use of the second MAC-CE entity structure is applicable to single-entity or multi-entity MAC-CE.

[0151] In some embodiments of this disclosure, single-entity and multi-entity only distinguish whether there are multiple carriers (cells), not whether they can carry auxiliary information. For a single-entity structure, the R field is not used to indicate whether it is a real PHR or a virtual PHR; instead, a line is added directly below the MAC-CE entity, which is a report of auxiliary information.

[0152] Therefore, it can be seen that the scheme of reporting auxiliary information using the first MAC-CE entity structure, the second MAC-CE entity structure or the third MAC-CE entity structure disclosed herein is applicable to single-entity MAC-CE or multi-entity MAC-CE.
