Abstract: A method comprising initiating a random access (RA) procedure, by a reconfiguration with sync, for a bandwidth part (BWP), in circumstances where the reconfiguration with sync was not initiated for recovery using an lower-layer triggered mobility (LTM) candidate configuration, in circumstances where the BWP was configured with the dedicated contention free RA resources for the 4-step RA type, performing 4-step RA, in circumstances where the active BWP was not configured with the dedicated contention free RA resources for the 4-step RA type: in circumstances where the BWP was configured with the dedicated contention free RA resources for the 2-step RA type, performing 2-step RA, in circumstances where the BWP was not configured with the dedicated contention free RA resources for the 2-step RA type, performing 4-step RA; in circumstances where the reconfiguration with sync was initiated for recovery using an LTM candidate configuration: in circumstances where the BWP is configured with RA resources for 2-step R

Abstract: A method comprising receiving a first Radio Resource Control (RRC) reconfiguration message, the first RRC reconfiguration message including: a conditional reconfiguration field that comprises a conditional reconfiguration, and a lower-layer triggered mobility (LTM) configuration field that comprises an LTM configuration, the conditional reconfiguration comprising an RRC reconfiguration field that includes a second RRC reconfiguration message, wherein the second RRC reconfiguration message comprises a master key update field and wherein the LTM configuration field is precluded from the second RRC reconfiguration message, the LTM configuration comprising an attempt LTM switch field and an RRC reconfiguration field that includes a third RRC reconfiguration message, wherein the conditional reconfiguration field, the LTM configuration field, and the master key update field are precluded from the third RRC reconfiguration message, detecting a radio link failure of a master cell group (MCG), determining a selected c

Abstract: A method comprising receiving, by a Packet Data Convergence Protocol (PDCP) entity, a plurality of PDCP SDUs for transmission, discarding at least one PDCP SDU from the plurality of PDCP SDUs for transmission, and transmitting a discard notification, the discard notification indicating the discarding of the PDCP SDU is disclosed.
