Embodiment Construction

[0022] In the prior art, if shared channel occupancy between the base station and UE can be realized, the system performance of NR-U can be greatly improved. Therefore, after discussion, 3GPP decided to use the physical downlink control channel PDCCH to notify UE of time-frequency information of channel occupancy.

[0023] Specifically, in the prior art, a Listen-Before-Talk (LBT) process may be used to implement coexistence of different operators and other systems in unlicensed spectrum. The LBT process means that a node in an unlicensed spectrum judges whether a current channel is available through a clear channel assessment (CCA) before transmitting data. It can be seen that any LBT process includes energy detection (Energy detection) to determine whether the channel is occupied. Some regional regulations stipulate an energy detection threshold (Energy detection threshold). If the received energy of a node is higher than this threshold, the channel is considered busy.

Abstract

Provided are an uplink control information reporting method and device, a storage medium and a user terminal. The method comprises the steps of determining time-frequency resource indication information of uplink channel occupation information, the time-frequency resource indication information being used for indicating a time-frequency resource of an uplink channel occupied by the user terminal;adopting preset time-frequency resources on a physical uplink shared channel (PUSCH) scheduled by a physical downlink control channel (PDCCH) and / or an authorized PUSCH to bear uplink indication information, wherein the uplink indication information comprises time-frequency resource indication information of the uplink channel occupation information; sending the PUSCH scheduled by the PDCCH and / orthe authorized PUSCH to a base station, so that the base station sends information to be sent according to the time-frequency resources of the uplink channel indicated by the time-frequency resourceindication information. According to the scheme of the invention, the duration of the uplink channel access process can be reduced, and the uplink and downlink communication efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and device for reporting uplink control information, a storage medium, and a user terminal. Background technique [0002] The 3rd Generation Partnership Project (The 3 rd The Generation Partnership Project (3GPP) standard organization will study how to deploy 5G New Radio (NR) networks on unlicensed spectrum, so as to achieve fair and effective use of unlicensed spectrum and improve the data transmission rate of NR systems. There are three ways for NR to use the unlicensed spectrum. One is: the NR cell of the unlicensed spectrum is the main cell; the other is: the user terminal (User Equipment, UE) accesses the NR cell of the unlicensed spectrum through the LTE cell, and finally One kind of NR cell for UE to access the unlicensed spectrum through the NR cell. The latter two methods of licensed spectrum and unlicensed spectrum can be used in combina...
