ROBUSTNESS ENHANCEMENTS OF EFFICIENT HARQ FEEDBACK

Systems and methods are disclosed for providing efficient downlink Hybrid Automatic Request (HARQ) feedback. In some embodiments, a method of operation of a wireless device in a cellular communications system comprises receiving a downlink control information message comprising a HARQ feedback buffer index and storing a downlink HARQ feedback flag in a position within a HARQ feedback buffer that corresponds to the HARQ feedback buffer index. In this manner, multiple downlink HARQ feedback flags can be stored in the HARQ feedback buffer and subsequently transmitted to a network node in an efficient manner.

ARQ system with status and packet acknowledgement

A communication system comprises a downlink indicator channel for the transmission of an indicator signal indicating that a data packet is scheduled to be transmitted on a downlink data channel from a primary station to a secondary station. In operation, on detection of the indicator signal, the secondary station transmits a status signal, for example a negative acknowledgement signal, on an uplink channel to the primary station immediately before transmission of a positive or negative acknowledgement signal to indicate the status of the received data packet. By providing the primary station with two chances to detect the case where the secondary station fails to detect the indicator signal, peak power requirements of the uplink channel can be reduced, thereby reducing system interference levels.

Systems and methods for managing feedback in a wireless network

A method of managing inter-cell interference in a wireless communication device includes obtaining information indicating a first set of candidate subframes. Each of the candidate subframe satisfies a candidate condition that relates to transmissions in a second cell during that subframe. The method also includes identifying at least one subframe associated with downlink transmissions to the wireless communication device in a first cell and determining whether the identified subframe is included in the set of candidate subframes. If the identified subframe is included in the set of candidate subframes, the method includes receiving at least one downlink transmission during the identified subframe. If the identified subframe is not included in the set of candidate subframes, the method includes performing one or more of assuming no downlink transmission will occur in the identified subframe, deciding to not receive a downlink transmission in the identified subframe, and assuming a pre-defined result for a downlink transmission associated with the identified subframe.
