Selection of acknowledgment timing in wireless communications
First Claim
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 HARQ module is to identify a reference time division duplex (TDD) configuration based on a first TDD configuration of a primary serving cell (PCell) and a second TDD configuration of a secondary serving cell (SCell), and the communication module is to transmit acknowledgement information associated with downlink data received through the SCell 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.

Abstract
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.

12. One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors of an apparatus, are to cause the apparatus to:
-
identify a downlink data received through a secondary serving cell (SCell) that has a second time division duplex (TDD) configuration; identify a reference TDD configuration based on a first TDD configuration of a primary serving cell (PCell) and the second TDD configuration; and transmit acknowledgement information associated with downlink data received through the SCell 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
