Abstract

A network for handling a downlink (DL) transmission in a frequency-division duplexing (FDD) system comprise a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise selecting a reference configuration for a DL transmission of a communication device from a plurality of configuration candidates; transmitting information of the reference configuration to the communication device; receiving a hybrid automatic repeat request (HARQ) feedback corresponding to the DL transmission from the communication device according to the reference configuration; and performing the DL transmission with the communication device according to the reference configuration.

Dependent claims

A network for handling a downlink (DL) transmission in a frequency-division duplexing (FDD) system, comprising:

a storage unit for storing instructions of:
selecting a first reference configuration for a DL transmission of a communication device from a plurality of configuration candidates, wherein the plurality of configuration candidates comprise at least one configuration for a hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) reporting in a time-division duplexing (TDD) system and at least one timing reference for the HARQ ACK/NACK reporting in a FDD-TDD carrier aggregation system;
transmitting information of the first reference configuration to the communication device;
performing the DL transmission with the communication device according to the first reference configuration;
and
receiving a HARQ feedback corresponding to the DL transmission from the communication device according to the first reference configuration, when a device-to-device (D2D) communication occurs in a first subframe which is four subframes after a second subframe where the DL transmission is performed;
and
a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
