Devices for sending and receiving hybrid automatic repeat request information for carrier aggregation

摘要

A User Equipment (UE) for sending Hybrid Automatic Repeat Request (HARQ) 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 UE further determines whether the PCell configuration specifies uplink (UL) and the SCell configuration specifies downlink (DL) for a subframe or whether the PCell configuration specifies DL and the SCell configuration specifies DL for the subframe. The UE additionally determines a HARQ Acknowledgement (HARQ-ACK) reporting subframe based on the PCell configuration if the PCell configuration specifies DL and the SCell configuration specifies DL for the subframe. The UE also sends SCell Physical Downlink Shared Channel (PDSCH) HARQ-ACK information in the HARQ-ACK reporting subframe.

1. A User Equipment (UE) for sending Hybrid Automatic Repeat Request (HARQ) information, comprising:
a processor; memory in electronic communication with the processor; instructions stored in the memory, the instructions being executable to:
determine a primary cell (PCell) configuration;determine a secondary cell (SCell) configuration;determine, for each subframe, whether the PCell configuration specifies uplink (UL) and the SCell configuration specifies downlink (DL) for the subframe or whether the PCell configuration specifies DL and the SCell configuration specifies DL for the subframe;determine a HARQ Acknowledgement (HARQ-ACK) reporting subframe, wherein the HARQ-ACK reporting subframe is determined based on the PCell configuration association timing if the PCell configuration specifies DL and the SCell configuration specifies DL for the subframe; andthe HARQ-ACK reporting subframe is determined based on a selected uplink-downlink (UL-DL) configuration and a subframe number if the PCell configuration specifies UL and the SCell configuration specifies DL for the subframe; andsend Physical Downlink Shared Channel (PDSCH) HARQ-ACK information of all serving cells for the subframe in the HARQ-ACK reporting subframe.
