Abstract

The invention discloses a bandwidth part BWP switching method for an asymmetric frequency spectrum. The method comprises the following steps: when first downlink control information (DCI) of a PDSCH (Physical Downlink Shared Channel) is not detected, resetting a timer according to the detected second DCI of the PDSCH; And when the reset timer is overtime, switching the current bandwidth part BWP to the default BWP. According to the invention, the terminal performs timer reset according to the joint determination of the first DCI for scheduling the PDSCH and the second DCI for scheduling the PUSCH, so that the problem of uplink scheduling ambiguity caused by BWP switching is avoided, and normal uplink transmission of the terminal in the BWP switching process can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a BWP switching method for a bandwidth part of an asymmetric frequency spectrum, a terminal and a network device. Background technique [0002] Compared with previous mobile communication systems, the future fifth generation (5 th Generation (5G) mobile communication system, or New Radio (NR) system, needs to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include mobile broadband enhanced eMBB, large-scale Internet of Things mMTC, and ultra-reliable and ultra-low-latency communication uRLLC. These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. In order to meet different needs of services and different application scenarios, the subcarrier spacing of the NR system is no longer the same as that of the traditional fourth generation (4 th Generation, 4...
