Problems solved by technology

If LCP only performs cell restriction without considering whether SUL carrier or non-SUL carrier is used, then when UE is configured to dynamically use SUL and non-SUL PUSCH resources, and if data is sent on a carrier with a poor channel, it will be difficult There may be transmission failures that require retransmissions, resulting in excessive delays, which may affect the performance of low-latency services

Abstract

The present disclosure relates to a supplementary uplink carrier SUL configuration method and device, a scheduling resource allocation method and device, a base station, user equipment, and a computerreadable storage medium. The SUL configuration method includes: generating a SUL related parameter, where the SUL related parameter is used to limit whether an uplink resource allocated to the logical channel is a SUL carrier resource or a non-SUL carrier resource on the qualified cell; sending the SUL related parameter to the UE. In the above embodiment, by generating and transmitting to the UE,the SUL related parameter for limiting whether the uplink resource allocated to the logical channel is the SUL carrier resource or the non-SUL carrier resource on the defined cell, whether the configuration logical channel adopts the SUL carrier resource or the non- SUL carrier resources to prevent data from being transmitted on carriers with poor channel, thereby reducing transmission delay andimproving service performance.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a Supplementary Uplink Carrier (SUL) configuration method and device, a scheduling resource allocation method and device, a base station, user equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of wireless communication technology, a fifth generation of mobile communication technology (5th Generation, 5G for short) appears. Regarding the logical channel prioritization (LCP) mechanism in the 5G system, LCP restrictions are introduced. The limiting factors include subcarrier spacing, Physical Uplink Shared Channel (PUSCH) transmission duration and cell limit. If a logical channel is configured with one or more of the above restrictions, when the user equipment (UE) receives an uplink (UL) scheduling (grant), its subcarrier spacing or PUSCH transmission duration or the cell it belongs to does not meet th...
