1. An apparatus comprising:

  • one or more computer-readable media having instructions; and

    one or more processors, coupled with the one or more computer-readable media, to execute the instructions to implement a communication module and a hybrid automatic repeat request (HARQ) module,wherein the communication module is to;

    establish communications with one or more base stations through a primary serving cell (PCell) and a secondary serving cell (SCell), the PCell to have a first time division duplex (TDD) configuration and the SCell to have a second TDD configuration; and

    receive downlink data through the SCell; and

    the (HARQ) module is to;

    select a reference TDD configuration based on the first and second TDD configurations; and

    transmit, via the communications module, acknowledgement information associated with the downlink data according to a HARQ timing of the reference TDD configuration, wherein;

    the acknowledgement information includes HARQ-acknowledgement (HARQ-ACK) signals;

    only HARQ-ACK signals associated with the downlink data of the SCell are to be transmitted according to the HARQ timing of the reference TDD configuration; and

    HARQ-ACK signals associated with downlink data of the PCell are to be transmitted only according to the HARQ timing of the first TDD configuration.
