Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communications, and in particular to a method and device for determining an information sending mode, a user terminal, and a communication system. 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 note 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 DFT (Discrete Fourier Transform) to CP (Cyclic Prefix) or from CP to DFT may involve the need to modify the MCS (Modulation and Coding Scheme) and the need to change the type of FDRA (Frequency Domain Resource Assignment). Therefore, if the transmission power of PUSCH cannot be understood in real time, it will lead to switching scheduling according to wrong information, thereby failing to effectively improve the transmission performance of PUSCH.
[0004] Based on this, the present disclosure provides a solution for determining the information sending method. By designing an effective auxiliary information reporting mechanism, it can ensure the effective reporting of uplink auxiliary information, thereby helping the network to better perform dynamic switching, ensuring the network's specific better coverage capabilities, and avoiding excessive signaling overhead.

[0099] By implementing the above-mentioned embodiments of the present disclosure and designing an effective auxiliary information reporting mechanism, effective reporting of uplink auxiliary information can be guaranteed, thereby helping the network to better perform dynamic switching, ensuring better network coverage capabilities, and avoiding excessive signaling overhead.
[0100] Fig.10 FIG. 1 is a schematic diagram of a device for determining an information sending mode according to an embodiment of the present disclosure. Fig.10 The information sending mode determination device includes a first processing module 1001 and a second processing module 1002.
[0101] The first processing module 1001 is configured to determine an uplink transmission timing.
[0102] In some embodiments, the first processing module 1001 determines a first time domain resource for a first uplink transmission on a first carrier, and determines a second time domain resource for a second uplink transmission on a second carrier, so as to determine whether there is overlap between the first time domain resource and the second time domain resource.
[0103] The second processing module 1002 is configured to determine a sending method of auxiliary information AI according to an uplink transmission timing, wherein AI includes at least one of a power headroom report PHR, a maximum transmit power, or a power difference between AI and PHR.
[0104] In some embodiments, when the first time domain resources at least partially overlap with the second time domain resources, the second processing module 1002 determines the sending method of the first PHR and the first AI of the first carrier, and the second PHR and the second AI of the second carrier according to the relationship between the first reference time of the first uplink transmission, the second reference time of the second uplink transmission, the first reference time period of the PHR, and the second reference time period of the AI.
[0105] For example, when the first reference time falls within the first reference time period and the second reference time period, and the second reference time does not fall within the first reference time period and the second reference time period, the second processing module 1002 determines to send the first PHR, the second PHR, the first AI, and the second AI on the first carrier.
[0106] For example, when the first reference time falls within the first reference time period and the second reference time period, and the second reference time period does not fall within the first reference time period but falls within the second reference time period, the second processing module 1002 determines to send the first PHR and the second PHR on the first carrier, and send the first AI and the second AI on the second carrier.
[0107] For example, when the first reference time falls within the first reference time period and does not fall within the second reference time period, and the second reference time does not fall within the first reference time period and falls within the second reference time period, the second processing module 1002 determines to send the first PHR and the second PHR on the first carrier, and send the first AI and the second AI on the second carrier.
[0108] In some embodiments, in the dynamic grant DG mode, the first reference time is the reception time of the first downlink control information DCI for scheduling the first uplink transmission. The second reference time is the reception time of the second DCI for scheduling the second uplink transmission.
[0109] In some embodiments, the second DCI and the first DCI are the same DCI, and the second uplink transmission and the first uplink transmission are the same uplink transmission, that is, the PHR and the AI are transmitted on the same PUSCH scheduled by the DCI.
[0110] In some embodiments, in the configuration authorization CG mode, the first reference time is the difference between the start transmission time of the first uplink transmission and the uplink transmission preparation time. The second reference time is the reception time of the second DCI for scheduling the second uplink transmission, or the difference between the start transmission time of the second uplink transmission and the uplink transmission preparation time.
