Abstract
Certain aspects of the present disclosure provide techniques and apparatus for radio link recovery procedure enhancements in wireless communication systems. In some cases, radio link recovery may be enhanced (e.g., sped up and network congestion reduced) by allowing a user equipment (UE) to use an additional secondary cell (SCell) serving the UE to assist in beam recovery when a layer one (L1) event is detected on a primary cell (PCell) or primary secondary cell (PSCell) of the UE.
Claims30
A method of wireless communication by a user equipment (UE), comprising:
- detecting a layer one (L1) event associated with at least one of a primary cell (PCell) serving the UE or a primary secondary cell (PSCell) serving the UE;
- triggering, in response to detecting the L1 event, a beam recovery procedure for at least one of the PCell or the PSCell, wherein triggering the beam recovery procedure includes transmitting a reconfiguration request via an additional secondary cell (SCell) to reconfigure at least one beam for at least one of the PCell or the PSCell;
- receiving request information via the additional SCell requesting identification information of the at least one beam to reconfigure;
- transmitting the requested identification information of the at least one beam;
- receiving, in response to transmitting the requested identification information, reconfiguration information for the at least one beam;
- and
- communicating, based on the reconfiguration information, with at least one of the PCell or the PSCell using the at least one beam.
A method of wireless communication by a base station, comprising:
- receiving, from a user equipment (UE) served by at least one of a primary cell (PCell) or a primary secondary cell (PSCell), a reconfiguration request to reconfigure at least one beam for at least one of the PCell or the PSCell in response to a layer one (L1) event at the UE associated with at least one of the PCell or the PSCell, wherein the reconfiguration request is received via an additional secondary cell (SCell) serving the UE;
- transmitting, to the UE, request information requesting identification information of the at least one beam to reconfigure;
- receiving, from the UE, the requested identification information of the at least one beam;
- and
- transmitting, in response to receiving the requested identification information, reconfiguration information for the at least one beam.
An apparatus for wireless communication by a user equipment (UE), comprising:
- at least one processor configured to:
- detect a layer one (L1) event associated with at least one of a primary cell (PCell) serving the UE or a primary secondary cell (PSCell) serving the UE;
- trigger, in response to detecting the L1 event, a beam recovery procedure for at least one of the PCell or the PSCell, wherein triggering the beam recovery procedure includes transmitting a reconfiguration request via an additional secondary cell (SCell) to reconfigure at least one beam for at least one of the PCell or the PSCell;
- receive request information via the additional SCell requesting identification information of the at least one beam to reconfigure;
- transmit the requested identification information of the at least one beam;
- receive, in response to transmitting the requested identification information, reconfiguration information for the at least one beam;
- and
- communicate, based on the reconfiguration information, with at least one of the PCell or the PSCell using the at least one beam;
- and
- a memory coupled with the at least one processor.
An apparatus for wireless communication by a base station of an secondary cell, comprising:
- at least one processor configured to:
- receive, from a user equipment (UE) served by at least one of a primary cell (PCell) and or a primary secondary cell (PSCell), a reconfiguration request to reconfigure at least one beam for at least one of the PCell or the PSCell in response to a layer one (L1) event at the UE associated with at least one of the PCell or the PSCell, wherein the reconfiguration request is received via an additional secondary cell (SCell) serving the UE;
- transmit, to the UE, request information requesting identification information of the at least one beam to reconfigure;
- receive, from the UE, the requested identification information of the at least one beam;
- and
- transmit, in response to receiving the requested identification information, reconfiguration information for the at least one beam;
- and
- a memory coupled with the at least one processor.
