Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may provide information identifying a band combination capability for carrier aggregation during a handover of the UE, wherein the band combination capability identifies a plurality of bands or carriers; and perform the handover based at least in part on the information identifying the band combination capability, wherein at least one first band or carrier, of the plurality of bands or carriers, is used for a source base station of the handover and at least one second band or carrier, of the plurality of bands or carriers, is used for a target base station of the handover. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus configured to establish a wireless connection to a first network, tune away from the first network for a first predetermined interval, tune back to the first network after the first predetermined interval, enter a power control freeze state for a second predetermined interval after tuning back to the first network, send a plurality of transmissions to the first network during the second predetermined interval, determine if a number of the plurality of transmissions that are not received by the first network exceeds a first threshold or if a number of the plurality of transmissions that are retransmitted to the first network exceeds a second threshold, and exit the power control freeze state when it is determined that the first threshold is exceeded or when it is determined that the second threshold is exceeded.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.
