Abstract
Embodiments of this application disclose a search space group switching method and apparatus. The method can be applied to a terminal and includes switching between at least two search space groups, and performing corresponding physical downlink control channel PDCCH monitoring based on a switched-to search space group, where the at least two search space groups include search space group #2, search space group #2 being not linked to any search space or a first search space, the first search space including at least one of a first type common search space CSS, a UE specific search space USS, and a CSS other than the first type CSS.

A search space group switching method applied to a terminal, wherein the method comprises:
- switching between at least two search space groups;
- and
- performing corresponding physical downlink control channel PDCCH monitoring based on a switched-to search space group;
- wherein
- the at least two search space groups comprise search space group #2, search space group #2 being not linked to a first search space, the first search space comprising a CSS other than a first type CSS, wherein the first type CSS is a type 3 CSS;
- wherein the at least two search space groups further comprise search space group #0 and search space group #1;
- and the switching between at least two search space groups comprises:
- switching from search space group #2 to search space group #0;
- wherein the switching from search space group #2 to search space group #0 comprises:
- switching from search space group #2 to search space group #0 after a first timer times out or after a first time interval has elapsed since a first timer times out.
A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein the program or instructions are executed by the processor to perform:
- switching between at least two search space groups;
- and
- performing corresponding physical downlink control channel PDCCH monitoring based on a switched-to search space group;
- wherein
- the at least two search space groups comprise search space group #2, search space group #2 being not linked to a first search space, the first search space comprising a CSS other than a first type CSS, wherein the first type CSS is a type 3 CSS;
- wherein the at least two search space groups further comprise search space group #0 and search space group #1;
- and the switching between at least two search space groups comprises:
- switching from search space group #2 to search space group #0;
- wherein the switching from search space group #2 to search space group #0 comprises:
- switching from search space group #2 to search space group #0 after a first timer times out or after a first time interval has elapsed since a first timer times out.
A non-transitory readable storage medium, wherein the readable storage medium stores a program or instructions, and the program or instructions are executed by a processor to perform:
- switching between at least two search space groups;
- and
- performing corresponding physical downlink control channel PDCCH monitoring based on a switched-to search space group;
- wherein
- the at least two search space groups comprise search space group #2, search space group #2 being not linked to a first search space, the first search space comprising a CSS other than a first type CSS, wherein the first type CSS is a type 3 CSS;
- wherein the at least two search space groups further comprise search space group #0 and search space group #1;
- and the switching between at least two search space groups comprises:
- switching from search space group #2 to search space group #0;
- wherein the switching from search space group #2 to search space group #0 comprises:
- switching from search space group #2 to search space group #0 after a first timer times out or after a first time interval has elapsed since a first timer times out.
