Embodiment Construction

[0050]In practical applications, it is easier to have limited coverage in the uplink direction than in the downlink direction. Therefore, the 5G NR standard also supports SUL technology. On the one hand, it can be considered to re-cultivate 900 / 1800 / F / A / E into the 5G frequency band, and use the full uplink spectrum SUL for uplink enhancement. For 6GHz / millimeter wave, etc., it can be considered to use Time Division Duplexing (TDD, Time Division Duplexing) + SUL for uplink enhancement. In the related protocols of 5G NR, the SUL carrier is defined by being associated with a traditional carrier pair including uplink and downlink, and SUL carrier selection is mainly based on SSB. In the idle state, the association between the 4.9GHz NR and the 2.3GHz SUL is configured and selected by broadcasting a System Information Block (SIB, System Information Block) 1 message or a Radio Resource Control (RRC, Radio Resource Control) reconfiguration message. The SUL related information is sen...

Abstract

The invention discloses an uplink carrier selection method and device, a terminal and a storage medium, and the method comprises the steps: a first terminal selects to access an SUL carrier or an UL carrier based on a first threshold when the first terminal is in an idle state; the first threshold is determined based on at least one of 5QI and slice identification corresponding to the service type of the first terminal; when the first terminal is in a connected state and in an NR uplink time slot, selecting to switch to an SUL carrier or an UL carrier in a first cell accessed by the first terminal based on the first measurement result, the second measurement result and the first information; wherein the first measurement result represents a measurement result of the SUL carrier of the first cell; the second measurement result represents a measurement result of the UL carrier of the first cell; the first information represents at least one of a first load corresponding to an SUL carrier of the first cell or a second load corresponding to an UL carrier of the first cell.

Description

technical field [0001] The present application relates to the field of wireless technologies, and in particular, to an uplink carrier method, device, terminal and storage medium. Background technique [0002] In the related protocols of the fifth generation mobile communication technology (5G) New Radio (NR, New Radio), the downlink carrier and the uplink carrier are bound one by one to define the supplementary uplink (SUL, Supplimentary Uplink) carrier, and The uplink SUL carrier selection is mainly based on a synchronization signal and a physical broadcast block (SSB, Synchronization Signal and PBCH block). In the related art, the terminal selects the uplink SUL carrier in the idle state and the connected state, which may lead to the problem of inaccurate selection of the SUL carrier, thereby causing loss of uplink performance. SUMMARY OF THE INVENTION [0003] In order to solve the related technical problems, the embodiments of the present application provide a method,...
