CONFIGURATION FOR DETECTION OF PHYSICAL HARQ INDICATOR CHANNEL

摘要

The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for configuring a detection of a E- PHICH (or PHICH in general) in DL for monitoring a PUSCH to reduce resource reservation for the PHICH and correspondingly reduce an impact on detection of (E-)PDCCH and (E-)PDSCH, e.g., in LTE-A systems. The UEs may be configured (e.g., by an eNB) to detect E-PHICH or not to detect: the configuration can be not to detect E-PHCIH at all, or always to detect it, or to detect only in some subframes. The configuration may be UE specific or common to a group of UEs. If a UE is configured not to detect E-PHICH in a DL subframe #n, and if according to the defined HARQ timing the UE needs to detect a HARQ-ACK information in the same subframe, then the UE will try to detect UL and/or DL grant in the subframe #n which will provide the desired HARQ (or ACK/NACK/DTX) information.
