Devices for sending and receiving feedback information

摘要

A User Equipment (UE) for sending feedback information is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE determines a primary cell (PCell) configuration. The UE also determines a secondary cell (SCell) configuration. The SCell configuration is different from the PCell configuration. The UE further determines a feedback parameter Mc based on the PCell configuration and the SCell configuration. Mc indicates a number of subframes that require Physical Downlink Shared Channel (PDSCH) Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) association for a cell c in a given uplink subframe. The UE also determines SCell HARQ-ACK information. The UE additionally sends the SCell HARQ-ACK information based on the feedback parameter.

1. A User Equipment (UE) for sending information to an evolved Node B, the UE comprising:
an operator configured to determine a Time-Division Duplexing (TDD) uplink-downlink (UL-DL) configuration of a primary cell (PCell) and a TDD UL-DL configuration of a secondary cell (SCell), wherein the TDD UL-DL configuration of the SCell is different from the TDD UL-DL configuration of the PCell; and a transmitter configured to transmit Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement information in an uplink subframe n for a cell, wherein the uplink subframe n corresponds to a subframe n−k of a Physical Downlink Shared Channel (PDSCH), wherein a set K includes one or more values of k such that the subframe n−k corresponds to a downlink subframe or a special subframe for the cell; wherein the set K for the PCell is determined based on the TDD UL-DL configuration of the PCell and the set K for the SCell is determined based on a TDD UL-DL configuration determined based on the TDD UL-DL configuration of the PCell and the TDD UL-DL configuration of the SCell.
