Shared HARQ feedback channels for virtual grouping in a wireless relay network

摘要

Various embodiments are disclosed, which may include transmitting a transmission schedule for a data burst to a plurality of relay stations in a wireless relay network. The transmission schedule may identify a data channel for transmission of the data burst and a corresponding shared negative acknowledgment feedback channel for transmission of a negative acknowledgment. The negative acknowledgment feedback channel may be shared by the plurality of relay stations.

主权项

1. A method comprising:
transmitting a transmission schedule for a downlink data burst to a plurality of relay stations in a wireless network, the transmission schedule identifying a downlink data channel for downlink transmission of the downlink data burst and a corresponding uplink shared feedback channel for uplink transmission of an acknowledgment or a negative acknowledgment, the feedback channel being shared by the plurality of relay stations; transmitting the downlink data burst to the plurality of relay stations via the downlink data channel; and receiving the acknowledgment or the negative acknowledgment via the uplink shared feedback channel from at least two of the plurality of relay stations at approximately a same time and via approximately a same frequency band.
