    Abstract: This disclosure provides systems, methods and apparatuses for adding and releasing secondary cells in a multi-cell connectivity configuration. In one aspect, a user equipment (UE) may transmit UE assistance information to a base station (BS) operating as a master cell in a multi-cell connectivity configuration. The UE assistance information may indicate a process that the BS is to use to add a secondary cell to the multi-cell connectivity configuration, may indicate a time gap for adding a secondary cell after another secondary cell is released from the multi-cell connectivity configuration, as well as other multi-cell connectivity configuration information. The BS may receive the UE assistance information and may add a secondary cell to the multi-cell connectivity configuration based at least in part on the indicated process and time gap.

    Abstract: Methods, systems, and devices for wireless communications are described. The method includes transmitting, to a base station based on a parameter of a configuration of the UE, a first HARQ feedback configuration or a request to modify the configuration of the UE, or both, the configuration of the UE including a carrier aggregation configuration and receiving, from the base station based on transmitting the first HARQ feedback configuration or request to modify the configuration of the UE, or both, a second HARQ feedback configuration or reconfiguration.

    Abstract: A user equipment (UE) speeds up circuit switched fallback call establishment and reduces circuit switched fallback call establishment failure. In one instance, the UE receives a redirection command including a list of current neighbor cells/frequencies. The UE determines whether a current serving cell matches a previous serving cell stored in the UE. The UE also evaluates the list of current neighbor cells to determine whether each current neighbor cell matches a previous neighbor cell associated with the previous serving cell. The UE then determines neighbor cells for power scan and/or synchronization channel decoding procedures to select one of the current neighbor cells to redirect the UE based on the previously recorded type of redirection result.

    Abstract: A method of wireless communication includes receiving an uplink grant for one or more pending HARQ processes waiting to perform a retransmission. The method also includes selecting each pending HARQ process that has not received a NACK. The method further includes terminating an oldest selected HARQ process when the uplink grant is insufficient to perform the retransmission for the plurality of pending HARQ processes.

    Abstract: A method of wireless communication includes recording an absolute system frame number (SFN) of a target radio access technology (RAT) and/or recording a relative system frame number (SFN) difference between a serving radio access technology (RAT) and the target RAT. A transmission time interval (TTI) boundary, is determined after redirection, based at least in part on the recorded absolute frame number (SFN) and/or the recorded relative system frame number (SFN) difference.

    Abstract: In an aspect of the disclosure, a method of wireless communication is provided. The method may include starting a first timer for changing to a first network cell with a first radio access technology (RAT) and starting a second timer for changing to a second network cell with a second RAT. Further, the method may include changing to the first network cell when the first timer expires. The method may also include determining that the second network cell satisfies a cell change condition and continuing to run the second timer after the change to the first network cell in response to the second network cell satisfying the cell change condition. The method may further include changing to the second network cell after starting a third timer for a third network cell with the first RAT, a duration of the second timer being longer than a duration of the third timer.
