First Claim
1. An apparatus for a user equipment (UE) comprising:
- baseband circuitry including processing circuitry configured to provide a Frequency Division Duplex-Time Division Duplex (FDD-TDD) hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback procedure for a primary serving cell (PCell) frame structure type-2, further configured to;
establish a connection to the primary serving cell (PCell) and a secondary serving cell (SCell) of an enhanced-Node B (eNB) of the LTE wireless communication network, the PCell having a TDD configuration and the SCell having a FDD configuration;
categorize a type of downlink data subframe in use by the SCell; and
select a hybrid automatic repeat request (HARQ) timing sequence configuration for use with downlink data received from the SCell based on the type of downlink data subframe received from the SCell; and
transceiver circuitry toreceive the downlink data through the PCell and SCell; and
transmit acknowledgement information associated with the downlink data subframe received from the SCell according to the selected hybrid automatic repeat request (HARQ) timing sequence configuration in an uplink (UL) subframe over the connection to the PCell;
wherein the PCell uses Type-2 subframes and the SCell uses Type-1 subframes,wherein the UE is configured to not monitor a Physical Downlink Control Channel (PDCCH)/Enhanced Physical Downlink Control Channel (EPDCCH) in another serving cell for scheduling the serving cell;
wherein a timing sequence configuration with which to transmit an acknowledgement/negative acknowledgement (ACK/NACK) comprises a table including values associated with an ACK/NACK for a DL subframe on the SCell to be transmitted in the UL subframe on the PCell, wherein a UL ACK/NACK transmission of subframe n is in subframe n-k, where k>
