Collision handling method and apparatus
A collision handling method and apparatus are provided. The method includes: a terminal device determines that PUR SS collides with Paging CSS; and the terminal device determines, based on a status of uplink data transmission in PUR associated with the PUR SS and/or a discontinuous reception DRX configuration status of the terminal device, to preferentially monitor the PUR SS or to preferentially monitor the Paging CSS. In the foregoing method, the terminal device determines, based on an actual situation, whether to preferentially monitor the PUR SS or preferentially monitor the paging CSS, so that when the terminal device is to preferentially monitor the PUR SS, the terminal device can receive a feedback of a network device for PUR transmission in time, and when the terminal device i to preferentially monitor the Paging CSS, it can be ensured that the terminal device can receive a paging message in time.
