HARQ process utilization in multiple carrier wireless communications
First Claim
1. A method for facilitating a wireless communication of data using hybrid automatic repeat request (HARQ) processes that are usable on multiple carriers for the wireless communication (joint HARQ processes), the method comprising:
- receiving on one of the carriers usable for the joint HARQ processes a wireless signal containing a data channel over which a transmission of data of the wireless communication is communicated via a joint HARQ process;
receiving on one of the carriers usable for the joint HARQ processes a wireless signal containing a control channel over which data is communicated from which a first part of an identity of the joint HARQ process is determinable;
receiving on one of the carriers usable for the joint HARQ processes a wireless signal containing additional information;
determining a first part of the joint HARQ process identity using received control channel data;
determining a second part of the joint HARQ process identity using additional information;
determining the joint HARQ process identity by combining the first part and the second part; and
using the determined joint HARQ process identity to process the received data transmission.

Abstract
Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.
