HARQ process number management for downlink carrier

摘要

A method and apparatus wherein the method comprises maintaining at least first and second Hybrid Automatic Repeat reQuest (HARQ) Process Groups (HPGs), receiving a downlink control information (DCI) message, using at least one of explicit information and implicit information associated with the DCI message to identify one of the HPGs, using at least one of explicit information and implicit information associated with the DCI message to identify a first carrier and generating a transmission of at least one data packet using the identified HPG to an access device via the carrier and a first uplink sub-frame.

1. A method comprising:
maintaining at least first and second Hybrid Automatic Repeat reQuest (HARQ) Process Groups (HPGs), wherein a combination of one of the at least first and second HPGs and a sub-frame number uniquely identifies a transmission stream and wherein the HPGs are indexed to specific carriers; receiving a downlink control information (DCI) message via a carrier; using a first information associated with the DCI message to identify one of the HPGs; using a second information associated with the DCI message to identify a first carrier; generating a transmission of at least one data packet using the identified HPG to an access device via the carrier and a first uplink sub-frame; monitoring a Physical Hybrid automatic repeat request Indicator CHannel (PHICH) for HARQ feedback related to the at least one data packet;wherein the first information comprises the DCI message carrier.
