Abstract
Wireless communications may comprise communications between a base station and a wireless device. A wireless device may perform a recovery procedure associated with a secondary cell and/or an access procedure associated with the secondary cell. Based on a deactivation condition associated with the secondary cell, the wireless device may deactivate the secondary cell during the access procedure.
Claims20
A method comprising:
- based on a beam failure associated with a secondary cell (SCell), transmitting, by a wireless device and via a primary cell (PCell), a random access preamble for a random access procedure;
- and
- based on a deactivation condition associated with the SCell during the random access procedure, deactivating the SCell during the random access procedure.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- based on a beam failure associated with a secondary cell (SCell), transmit, via a primary cell (PCell), a random access preamble for a random access procedure;
- and
- based on a deactivation condition associated with SCell during the random access procedure, deactivate the SCell during the random access procedure.
3 more elements
One or more non-transitory computer readable media storing instructions that, when executed cause:
- based on a beam failure associated with a secondary cell (SCell), transmit, via a primary cell (PCell), a random access preamble for a random access procedure;
- and
- based on a deactivation condition associated with SCell during the random access procedure, deactivate the SCell during the random access procedure.
