Abstract

The invention discloses a bandwidth part BWP switching method of asymmetric spectrum, terminal and network equipment. The method includes: when first downlink control information DCI for scheduling a physical downlink shared channel PDSCH is not detected, according to the detected scheduling The second DCI of the physical uplink shared channel PUSCH resets the timer; when the reset timer expires, the current bandwidth part BWP is switched to the default BWP. The terminal of the present invention jointly determines to reset the timer according to the first DCI scheduling PDSCH and the second DCI scheduling PUSCH, so as to avoid the problem of uplink scheduling ambiguity caused by BWP switching, and ensure the normal uplink transmission of the terminal during the BWP switching process. .

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...
