`ABSTRACT
`Apparatus and methods are provided for power - efficient
`operation for wide bandwidth . In one novel aspect , the
`configuration of the CORESET with CSS includes at least
`one of the time duration of the CORESET within a slot and
`the periodicity of the CORESET burst . In another embodi
`ment , each configured BWP includes at least one CORESET
`with UE - specific search space and one CORESET with CSS .
`In another embodiment , at least one of the configured BWPs
`includes one CORESET with type - 1 CSS for PCell . Each
`configured BWPs includes one CORESET with type - 2 CSS
`for both PCell and SCell and at least one CORESET with
`UE - specific search space for PCell and SCell . In another
`novel aspect , a timer - triggered transmission of activating
`DL BWP indication in all DL BWP configured is used when
`the UE mis - detects or false - alarms the explicit signaling for
`BWP switch .

`CORESET with CSS includes at least one of the time
`The disclosed embodiments relate generally to wireless

`BACKGROUND
`CORESET with UE - specific search space . At least one of
`the configured BWP includes one CORESET with CSS .
`Mobile networks communication continues to grow rap
`In another embodiment , the CORESET with CSS is
`idly . The mobile data usage will continue skyrocketing . New 25 configured as two types , the type - 1 CSS for broadcast
`data applications and services will require higher speed and
`messages , which is cell - specific and may require beam
`more efficient . Large data bandwidth application continues
`sweeping ; and the type - 2 CSS for multi - cast messages ,
`to attract more consumers . New technologies are developed
`which is group - specific . In one embodiment , at least one of
`to meet the growth such as carrier aggregation ( CA ) , which
`the configured BWPs includes one CORESET with type - 1
`enables operators , vendors , content providers and the other 30 CSS for PCell . Each configured BWP includes one CORE
`mobile users to meet the increasing requirement for the data

`configured BWP includes at least one CORESET with
`RF chains for signal reception even for physically contigu
`UE - specific search space for PCell and SCell . In yet another

`In another novel aspect , a timer - triggered transmission of

`The single carrier operation for such large continuous spec- 40 activating DL BWP indication in all DL BWP configured is
