SELECTION OF ACKNOWLEDGMENT TIMING IN WIRELESS COMMUNICATIONS

摘要

Disclosed is a method including communicating, by a mobile device, with a base station via first and second component carriers having different frequency bands and time division duplexing (TDD) configurations. The method may include receiving one or more downlink transmissions via the second component carrier. The method may include selecting a hybrid automatic repeat request (HARQ) timing sequence based on the TDD configurations of the first and second component carriers. The method may include transmitting one or more positive acknowledgment and/or negative acknowledgement (ACK/NACK) signals, associated with the one or more downlink transmissions, according to the selected HARQ timing sequence. Other embodiments may be described and claimed.

1. An apparatus comprising:
a communication module 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;receive downlink data through the SCell; and a hybrid automatic repeat request (HARQ) module to:
select a reference TDD configuration based on the first and second TDD configurations; andtransmit, 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.
