4 . The method of claim 3 , wherein the step of stopping monitoring for the physical downlink control channel in the search space set in response to no search space set or no monitoring occasion being included in the first search space set group comprising:
stopping monitoring for the physical downlink control channel in the search space set in response to an event not occurring, wherein the event comprises one of a scheduling request, a random access procedure, and a beam failure recovery procedure.
5 . The method of claim 1 , further comprising:
monitoring a default search space set according to the value in response to no search space set being included in the first search space set group.
6 . The method of claim 5 , wherein the step of monitoring the default search space set according to the value in response to no search space set being included in the first search space set group comprising:
monitoring the default search space set in response to an event occurring, wherein the event comprises one of a scheduling request, a random access procedure, and a beam failure recovery procedure.
7 . The method of claim 1 , further comprising:
receiving second configured information corresponding to a timer; and
monitoring for the physical downlink control channel in the search space set while the timer is running.
8 . The method of claim 7 , further comprising:
starting monitoring for the physical downlink control channel in a default search space set after the timer expiring.
9 . The method of claim 1 , wherein a format of the downlink control information comprises one of downlink control information 0_1, downlink control information 0_2, downlink control information 1_1, and downlink control information 1_2.
10 . The method of claim 1 , wherein the downlink control information further includes a number of search space set groups.
11 . A user equipment, comprising:
one or more non-transitory computer-readable media having computer-executable instructions embodied thereon; and
at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
receive first configured information corresponding to a plurality of search space set groups, wherein a number of the plurality of search space set groups is greater than two;
receive a downlink control information (DCI) which includes a DCI field with a value indicating a first search space set group in the plurality of search space set groups according to the first configured information; and
monitor for a physical downlink control channel in a search space set in response to the search space set being included in the first search space set group.
12 . The user equipment of claim 11 , wherein one of the plurality of search space set groups includes no search space set or no monitoring occasion.
13 . The user equipment of claim 11 , wherein the at least one processor further configured to execute the computer-executable instructions to:
stop monitoring for the physical downlink control channel in the search space set in response to no search space set or no monitoring occasion being included in the first search space set group.
14 . The user equipment of claim 13 , wherein the at least one processor further configured to execute the computer-executable instructions to:
stop monitoring for the physical downlink control channel in the search space set in response to an event not occurring, wherein the event comprises one of a scheduling request, a random access procedure, and a beam failure recovery procedure.
15 . The user equipment of claim 11 , wherein the at least one processor further configured to execute the computer-executable instructions to:
monitor a default search space set according to the value in response to no search space set being included in the first search space set group.
16 . The user equipment of claim 15 , wherein the at least one processor further configured to execute the computer-executable instructions to:
monitor the default search space set in response to an event occurring, wherein the event comprises one of a scheduling request, a random access procedure, and a beam failure recovery procedure.
17 . The user equipment of claim 11 , wherein the at least one processor further configured to execute the computer-executable instructions to:
receive second configured information corresponding to a timer; and
monitor for the physical downlink control channel in the search space set while the timer is running.
18 . The user equipment of claim 17 , wherein the at least one processor further configured to execute the computer-executable instructions to:
start monitoring for the physical downlink control channel in a default search space set after the timer expiring.
