Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information sending method, system, terminal, and readable storage medium. Background Art

[0002] The uplink coverage of 5G networks is a major bottleneck of network coverage, and because the coverage capabilities of uplink channels are quite different from those of downlink channels, the uplink channels need to be further enhanced. Dynamic waveform switching is a method for uplink enhancement. It can improve the transmission performance of PUSCH by real-time scheduling of the waveform of PUSCH (Physical Uplink Shared Channel) to ensure that PUSCH is transmitted at a reasonable rate and bit rate. In this way, the uplink transmission rate can be improved in real time when the network quality is good, and the transmission quality can be better guaranteed when the network quality is poor. Summary of the invention

[0003] The inventors found that: in the related art, waveform switching can be indicated in a relatively simple manner, such as by 1 bit or by reusing an existing indication field for switching indication. However, the process of switching from a DFT-S-OFDM (Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing) waveform to a CP-OFDM (Cyclic Prefix Orthogonal Frequency Division Multiplexing) waveform or from a CP-OFDM waveform to a DFT-S-OFDM waveform may involve the need to modify the MCS (Modulation and Coding Scheme), the need to change the type of FDRA (Frequency Domain Resource Assignment), and the different power control of the two waveforms. If the network performs blind switching, it may cause incorrect switching, affecting the uplink transmission performance.

[0004] A technical problem to be solved by the present disclosure is: how to improve the rationality and accuracy of dynamic waveform switching, thereby improving the uplink transmission performance after dynamic waveform switching.

[0039] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] The present disclosure proposes a method for sending information. Figure 1 to Figure 2G Give a description.

[0041] Figure 1 The following is a flowchart of some embodiments of the information sending method disclosed in the present invention. Figure 1 As shown, the method of this embodiment includes: steps S102 to S104.

[0042] In step S102, a triggering mechanism for the auxiliary information and a method for sending the auxiliary information are determined.

[0043] Assistant Information (AI) is used as reference information for the network device to perform dynamic waveform switching. The network device refers to the auxiliary information instead of blind switching when performing dynamic waveform switching. In some embodiments, the auxiliary information includes at least one of PHR (Power Headroom Report), PCmax (maximum transmit power), and the power difference between the auxiliary information and the PHR. The triggering mechanism of the auxiliary information and the sending method of the auxiliary information can be determined according to the configuration information, and the configuration information can include relevant indication information of the triggering mechanism and the sending method.

[0044] In some embodiments, the triggering mechanism of the auxiliary information includes at least one of periodic triggering and triggering when the network device is configured with a different PUSCH waveform.

[0045] In some embodiments, the periodic triggering includes at least one of the following: starting the periodic triggering after the terminal accesses the network, and starting the periodic triggering after the PHR is triggered. After the PHR (reporting) is triggered, starting the reporting of the PHR, and starting the periodic reporting of the auxiliary information at a preset interval, the PHR can be a PHR of one waveform, and the auxiliary information can be a PHR of another waveform.

[0046] like Figures 2A to 2D As shown, the triggering mechanism of the auxiliary information is periodic triggering. Figure 2A and 2B After the terminal accesses the network, the periodic triggering of auxiliary information is enabled. Figure 2C and 2D In the example, the periodic triggering of auxiliary information is enabled after the PHR is triggered.

[0047] In some embodiments, triggering when the network device is configured with a different PUSCH waveform includes at least one of the following: triggering when the network device is configured with a PUSCH waveform different from that in the random access process after the random access process, and triggering when the network device is configured with a PUSCH waveform different from the previous PUSCH waveform after the random access process.

[0048] During the random access process, MSG3 (Message 3) is transmitted on PUSCH. If after the random access process, the network configures a normal PUSCH waveform different from MSG3, auxiliary information reporting is triggered. During the communication process after the random access process, if the network configures a waveform different from the previous PUSCH waveform, auxiliary information reporting is triggered.

[0049] like Figures 2E to 2G As shown, the triggering mechanism of the auxiliary information is triggered when the network device is configured with a different uplink shared channel PUSCH waveform. Figure 2E and 2F When a normal PUSCH waveform different from MSG3 is configured for the network, auxiliary information reporting is triggered. Figure 2G When a waveform different from the previous PUSCH waveform is configured for the network, auxiliary information reporting is triggered.

[0050] In some embodiments, determining the sending method of the auxiliary information includes at least one of the following: determining a carrier for sending the auxiliary information as a first carrier; determining resources on the first carrier for sending the auxiliary information; and determining a type of the auxiliary information.

[0051] In a single carrier scenario, the carrier (ie, the first carrier) that sends the auxiliary information is the current carrier. In a multiple carrier scenario, the auxiliary information on each carrier can be sent on its own carrier, that is, each carrier can be used as the first carrier.

[0052] In some embodiments, in a scenario of multiple carriers, the carrier for sending the auxiliary information is determined based on at least one of the following: the time domain overlap of the uplink resources for scheduling the auxiliary information on each of the multiple carriers after the current trigger moment, the sending time of the uplink resources for scheduling the auxiliary information on each carrier, the receiving time of the DCI (Downlink Control Information) for scheduling the auxiliary information on each carrier, and the PUSCH waveform changes on each carrier.

[0053] When triggered when the network device is configured with different PUSCH waveforms, the first carrier is determined mainly by referring to the PUSCH waveform changes of each carrier. In the case of periodic triggering, the first carrier can be determined by referring to at least one of the other three types of information.

[0054] In some embodiments, when the trigger mechanism is a periodic trigger, the current trigger moment is the start moment of the current period; and / or when the trigger mechanism is triggered when the network device is configured with different PUSCH waveforms, the trigger moment is the reception moment of the DCI of the scheduling auxiliary information on each carrier or the preparation time node of the CG (Configured Grant) PUSCH of each carrier.

[0055] like Figures 2A to 2D As shown in , in the case of periodic triggering, if the current cycle is the Mth cycle, the current triggering time is the start time of the Mth cycle, that is, the time corresponding to AI is triggered. Figures 2E to 2G As shown, when the network device is configured with different PUSCH waveforms, in the case of DG (Dynamic Grant, dynamic authorization) (such as Figure 2E and 2G ), the current trigger moment on Cell 1 (carrier 1) is the reception moment of the DCI that schedules auxiliary information on Cell 1. In the case of CG, the current trigger moment on Cell 1 (carrier 1) is the preparation time node of CG PUSCH.

[0056] In some embodiments, when there is time domain overlap in the uplink resources for scheduling auxiliary information on each carrier, the carrier where the uplink resources with the earliest transmission time among the uplink resources for scheduling auxiliary information on each carrier are located is determined as the first carrier, which is applicable to DG and CG scenarios. Alternatively, when there is time domain overlap in the uplink resources for scheduling auxiliary information on each carrier, the carrier where the DCI with the earliest reception time among the DCI for scheduling auxiliary information on each carrier is located is determined as the first carrier, which is applicable to DG scenarios.

[0057] Auxiliary information can be triggered in a periodic manner in a cell (carrier) or terminal with reporting capability. If there is no uplink transmission in the current trigger period, the auxiliary information will not be reported. If there is uplink transmission, it will be reported. If the uplink resources for scheduling auxiliary information on multiple carriers overlap in time domain during reporting, the auxiliary information can be reported uniformly or separately on each carrier. If reported uniformly, the carrier where the first new uplink transmission in the current trigger period is located is used as the first carrier, that is, the carrier where the uplink resources with the earliest sending time among the uplink resources for scheduling auxiliary information on each carrier are located is used as the first carrier, or the first carrier that receives DCI in the current trigger period is used as the first carrier, that is, the carrier where the DCI with the earliest receiving time among the DCI for scheduling auxiliary information on each carrier is located is used as the first carrier.

[0058] like Figure 2A and 2B As shown in FIG. 1 , the PUSCHs of Cell 1 (carrier 1) and (Cell 2) overlap in the time domain. The PUSCH of auxiliary information scheduled on Cell 1 is earlier, so Cell 1 is used as the first carrier. Figure 2A As shown, the DCI reception time of Cell 1 scheduling auxiliary information is earlier, so Cell 1 is used as the first carrier.

[0059] In some embodiments, the carrier with the PUSCH waveform change among the carriers is determined as the first carrier. When the network device is configured with different PUSCH waveforms, the carrier with the PUSCH waveform change is directly used as the first carrier. If there are multiple carriers with PUSCH waveform changes, they are all used as the first carrier, and auxiliary information is transmitted on each carrier, such as Figures 2E to 2G shown.

[0060] If the PHR and the auxiliary information are reported separately, and the determination of the sending method of the auxiliary information can refer to the triggering and resources of the PHR, etc., which will be described below in conjunction with specific embodiments.

[0061] In some embodiments, in the scenario of multiple carriers, after the PHR (report) is triggered, the carrier for sending the auxiliary information is determined according to at least one of the time domain overlap of the uplink resources for scheduling the PHR and auxiliary information on each carrier in the multiple carriers after the current triggering moment, the sending time of the uplink resources for scheduling the PHR and auxiliary information on each carrier, and the receiving time of the downlink control information DCI for scheduling the PHR and auxiliary information on each carrier. It is mainly applicable to the case of periodic triggering, and the current triggering moment is the start moment of the current period.

[0062] In some embodiments, when the uplink resources for scheduling PHR and auxiliary information on each carrier overlap in time domain, the carrier where the uplink resources with the earliest sending time among the uplink resources for scheduling PHR and auxiliary information on each carrier are located is determined as the first carrier, which is applicable to DG and CG scenarios; or, when the uplink resources for scheduling PHR and auxiliary information on each carrier overlap in time domain, the carrier where the DCI with the earliest receiving time among the DCI for scheduling PHR and auxiliary information on each carrier is located is determined as the first carrier, which is applicable to DG scenarios.

[0063] Auxiliary information can be triggered in a cell (carrier) or terminal with reporting capability in a periodic manner after PHR is triggered. If there is no uplink transmission in the current trigger period when triggered, the auxiliary information will not be reported. If there is uplink transmission, the auxiliary information will be reported. If the uplink resources of PHR and auxiliary information scheduled on multiple carriers overlap in time domain when reporting, the auxiliary information and PHR can be reported uniformly or PHR can be reported separately on the carrier that schedules PHR, and auxiliary information can be reported on the carrier that schedules auxiliary information. If reported uniformly, the carrier where the first new uplink transmission in the current trigger period is located is used as the first carrier, that is, the carrier where the uplink resources with the earliest sending time among the uplink resources that schedule PHR and auxiliary information on each carrier are located is used as the first carrier, or the carrier that first receives DCI in the current trigger period is used as the first carrier, that is, the carrier where the DCI with the earliest receiving time among the DCI that schedules PHR and auxiliary information on each carrier is located is used as the first carrier.

[0064] like Figure 2C and 2D As shown in FIG. 1 , the PHR PUSCH of Cell 1 (carrier 1) and the PUSCH of (Cell 2) overlap in the time domain. The PHR PUSCH is scheduled earlier on Cell 1, so Cell 1 is used as the first carrier. Or, Figure 2C As shown, the DCI reception time of Cell 1 scheduling PHR is earlier, so Cell 1 is used as the first carrier.

[0065] If a carrier has received DCI for scheduling PHR, auxiliary information of the carrier may be transmitted simultaneously on the PUSCH for scheduling PHR of the carrier, and the PHR and the auxiliary information may correspond to different PUSCH waveforms respectively.

[0066] The above embodiment describes a method for determining the first carrier. The following describes how to determine resources for sending auxiliary information on the first carrier.

[0067] In some embodiments, the first time domain resource occupied by the uplink resource for scheduling auxiliary information on the first carrier is determined as the resource for sending auxiliary information on the first carrier; and / or the first time slot where the uplink resource for scheduling auxiliary information on the first carrier is located is determined as the resource for sending auxiliary information on the first carrier.

[0068] The reporting position of the auxiliary information is located in the first new uplink transmission in the trigger period, that is, the first time domain resource and / or the first time slot occupied by the uplink resource for scheduling the auxiliary information on the first carrier. Figure 2A and 2B As shown, the first time domain resources and / or the first time slot occupied by the PUSCH for scheduling auxiliary information on Cell 1 are used as resources for sending the auxiliary information.

[0069] like Figure 2E , 2F As shown in FIG. 2G, when the network device is configured with a different uplink shared channel PUSCH waveform and triggered, Cell 1 serves as the first carrier, and the first time domain resources and / or the first time slot occupied by the PUSCH for scheduling auxiliary information on Cell 1 are used as resources for sending auxiliary information.

[0070] In some embodiments, when the uplink resource for scheduling PHR on the first carrier is the uplink resource with the earliest sending time, or the DCI for scheduling PHR is the DCI with the earliest receiving time, the second time domain resource occupied by the uplink resource for scheduling PHR on the first carrier is determined as the resource for sending auxiliary information on the first carrier, and / or the second time slot in which the uplink resource for scheduling PHR on the first carrier is located is determined as the resource for sending auxiliary information on the first carrier.

[0071] like Figure 2C and 2D As shown, the second time domain resources and / or the second time slot occupied by the PUSCH of the scheduled PHR on Cell 1 are used as resources for sending auxiliary information.

[0072] After the first carrier is determined, resources on the first carrier for sending the auxiliary information also need to be determined. In a scenario of multiple carriers, the auxiliary information includes auxiliary information of each carrier.

[0073] In a single-carrier scenario, the auxiliary information transmitted by the single carrier is of the first type. The first type of auxiliary information is, for example, real auxiliary information, and the second type of auxiliary information is, for example, virtual auxiliary information.

[0074] In some embodiments, the auxiliary information of the first carrier is determined to be of the first type; the reference time period of the second carrier is determined according to the current trigger moment and the reference time point, and the type of the auxiliary information of the second carrier is determined according to the reception time of the downlink control information DCI of the scheduling auxiliary information on the second carrier and the reference time period. The second carrier is a carrier other than the first carrier among multiple carriers. Applicable to the case of periodic triggering, the current trigger moment is the start moment of the current period.

[0075] In some embodiments, in DG mode, the reference time point is the earliest reception time of DCI scheduling auxiliary information on each of multiple carriers; and / or in CG mode, the earliest preparation time node for configuring authorized CG PUSCH on each carrier.

[0076] In some embodiments, when the reception time of the DCI for scheduling auxiliary information on the second carrier is within the reference time period, the auxiliary information of the second carrier is of the first type; and / or when the reception time of the DCI for scheduling auxiliary information on the second carrier is not within the reference time period, the auxiliary information of the second carrier is of the second type.

[0077] If no DCI scheduling auxiliary information is received on the second carrier within the reference time period, the auxiliary information of the second carrier is of the second type.

[0078] In DG mode, the reference time gap (AI Reference time gap) is the time gap between the current triggering time and the earliest reception time of the DCI scheduling auxiliary information on each carrier. Figure 2A As shown in , the reference time period is the time period between the current triggering moment and the receiving moment of the AI ​​DCI on Cell 1. If the DCI of the scheduling auxiliary information on Cell 2 is outside the reference time period, the auxiliary information of Cell 2 is of the second type, namely Virtual AI. Figure 2C As shown, the reference time period is the time period between the current triggering moment and the reception moment of AI DCI (the earliest DCI of scheduling auxiliary information) on Cell 2. If the DCI of scheduling auxiliary information on Cell 2 is within the reference time period, the auxiliary information of Cell 2 is of the first type, i.e., Real AI. Figure 2CAs shown, the PHR reference time period is the time period between the PHR triggering time and the earliest reception time of the DCI scheduling the PHR on each carrier. If the reception time of the DCI scheduling the PHR on the second carrier is within the reference time period, the PHR of the second carrier is of the first type, otherwise it is of the second type. Figure 2C As shown, the PHR of Cell 2 is of the second type, namely, Virtual PHR.

[0079] In CG mode, the reference time period is the time period between the current triggering moment and the earliest preparation time node for configuring the authorized CG PUSCH on each carrier. Figure 2B As shown in , the reference time period is the current triggering moment and the preparation time node of CGPUSCH on Cell 1. T'proc,2 = Tproc,2 represents the preparation time of CG PUSCH. Figure 2D As shown in FIG, the reference time period is the current triggering moment and the preparation time node of CG PUSCH on Cell 2. In addition, as Figure 2D As shown, the PHR reference time period is the time period between the PHR triggering moment and the earliest preparation time node of the CG PUSCH corresponding to the PHR on each carrier. If the reception time of the DCI scheduling the PHR on the second carrier is within the reference time period, the PHR of the second carrier is of the first type, otherwise it is of the second type. Figure 2D As shown, the PHR of Cell 2 is of the second type, namely, Virtual PHR.

[0080] In step S104, the auxiliary information is sent to the network device according to the triggering mechanism of the auxiliary information and the sending method of the auxiliary information.

[0081] According to the trigger mechanism of the auxiliary information, it can be determined when to trigger the reporting of the auxiliary information, and according to the sending method of the auxiliary information, it can be determined how to send the auxiliary information. Therefore, the terminal can send the auxiliary information to the network device according to the trigger mechanism of the auxiliary information and the sending method of the auxiliary information.

[0082] In the above embodiment, the terminal determines the trigger mechanism and sending method of the auxiliary information, and sends the auxiliary information to the network. The auxiliary information is used as reference information for the network device to perform dynamic waveform switching. When the terminal sends the auxiliary information to the network device periodically or when the network device is configured with different PUSCH waveforms, it can assist the network to reasonably perform dynamic waveform switching, improve the rationality and accuracy of dynamic waveform switching, thereby improving the uplink transmission performance and ensuring the coverage capability of the network.

[0083] The present disclosure also provides a terminal, Figure 3 Give a description.

[0085] The determination module 310 is used to determine the triggering mechanism of the auxiliary information and the sending method of the auxiliary information, wherein the auxiliary information serves as reference information for the network device to perform dynamic waveform switching, and the triggering mechanism of the auxiliary information includes: at least one of periodic triggering and triggering when the network device is configured with different uplink shared channel PUSCH waveforms.

[0087] In some embodiments, the periodic triggering includes at least one of the following: starting the periodic triggering after the terminal accesses the network, and starting the periodic triggering after the power headroom report PHR is triggered.

[0088] In some embodiments, triggering when the network device is configured with a different uplink shared channel PUSCH waveform includes at least one of the following: triggering when the network device is configured with a PUSCH waveform different from that in the random access process after the random access process, and triggering when the network device is configured with a PUSCH waveform different from the previous PUSCH waveform after the random access process.
