Abstract
Wireless communications systems and methods related to updating a physical downlink control channel (PDCCH) monitoring parameter are provided. A user equipment (UE) determines a PDCCH monitoring parameter based on a current operating parameter. The UE transmits a PDCCH monitoring configuration request including the PDCCH monitoring parameter to a base station (BS). The BS may adjust the PDCCH monitoring parameter in accordance with the PDCCH monitoring configuration request. The UE may monitor PDCCH based on the PDCCH monitoring parameter.
Claims22
A method of wireless communication performed by a user equipment (UE), comprising:
- transmitting, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);
- transmitting, to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;
- receiving, from the network unit, a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index;
- and
- monitoring for a PDCCH using the third value for the PDCCH monitoring parameter.
2 more elements
A user equipment (UE), comprising:
- a memory;
- a transceiver;
- and
- at least one processor coupled to the memory and the transceiver, wherein the at least one processor is configured, alone or in any combination, to cause the UE to:
- transmit, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);
- transmit, to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;
- receive a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index;
- and
- monitor for a PDCCH using the third value for the PDCCH monitoring parameter.
6 more elements
A non-transitory computer-readable medium having program code recorded thereon executable by one or more processors for wireless communication by a user equipment (UE), the program code comprising:
- code for causing the UE to transmit, to a network unit, a capability report of the UE, the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);
- code for causing the UE to transmit to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;
- code for causing the UE to receive a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index;
- and
- code for causing the UE to monitor, for a PDCCH using the third value for the PDCCH monitoring parameter.

An apparatus, comprising:
- means for transmitting, to a network unit, a capability report of a user equipment (UE), the capability report specifying a first value for a physical downlink control channel (PDCCH) monitoring parameter, wherein the PDCCH monitoring parameter is one of a maximum number of monitored PDCCH candidates or a maximum number of non-overlapping control channel elements (CCEs);
- means for transmitting, by the UE to the network unit in response to a trigger based on a current operating parameter of the UE, a PDCCH monitoring configuration request including a second value for the PDCCH monitoring parameter less than the first value based on the current operating parameter of the UE;
- means for receiving a response to the PDCCH monitoring configuration request including a third value for the PDCCH monitoring parameter different than the second value, wherein the response includes an indication indicating a set of selected PDCCH candidate indices based on priorities of PDCCH candidates associated with a PDCCH candidate index;
- and
- means for monitoring, by the UE, for a PDCCH using the third value for the PDCCH monitoring parameter.
