Description

Cross-reference of related applications: This disclosure is based on Chinese Patent Application No. CN202310577810.2, filed on 22 May 2023, which claims priority, and its disclosure is incorporated herein by reference in its entirety. This disclosure relates to the field of information and communication, particularly to auxiliary information reporting methods and systems, terminals, and computer-readable storage media. Uplink coverage in 5G networks is a major bottleneck in network coverage, and since the difference in coverage capacity between uplink and downlink channels is tens of dB, further enhancement of the uplink channels is necessary. Dynamic waveform switching is a method for uplink enhancement. By scheduling the waveform of the PUSCH (Physical Uplink Shared Channel) in real time, it is possible to ensure that PUSCH transmission is at the appropriate rate and code rate, thereby improving the transmission performance of the PUSCH. This is a schematic diagram of several embodiments of the auxiliary information reporting method described herein.This is a schematic diagram of another embodiment of the auxiliary information reporting method described herein.These are schematic diagrams of several embodiments of the first MAC-CE structure of the supplementary information provided in this disclosure.In some embodiments of this disclosure, the diagram shows MAC-CE entries that define a new LCID table for distinguishing auxiliary information.These are schematic diagrams of several embodiments of the second MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of another embodiment of the second MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of yet another embodiment of the second MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of yet another embodiment of the second MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of yet another embodiment of the second MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of yet another embodiment of the second MAC-CE structure of the supplementary information provided in this disclosure.These are schematic diagrams of several embodiments of the third MAC-CE structure of the supplementary information provided in this disclosure.This is a schematic diagram of several embodiments of the terminal according to this disclosure.This is a schematic diagram of another embodiment of the terminal according to this disclosure.This is a schematic diagram of several embodiments of the auxiliary information reporting system described herein.

In the following diagrams, the same reference number and letter 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. Through their research, the inventors discovered that waveform switching can be represented by one bit of information or by multiplexing existing instruction fields. While this may seem simple and crude, it actually has a significant impact. One technical problem is that because the waveforms before and after switching differ, the power backoff also differs. Therefore, 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.
