Abstract:
In one or more aspects, the method and apparatus presented herein consider corresponding uplink resource allocations when allocating ARQ signal powers. In particular, in at least one embodiment, more power is allocated to the acknowledgment (“ack”) signal(s) corresponding to user equipment (UE) transmissions that involve larger allocations of uplink resources. For the example context of an LTE network, an eNodeB “boosts” its ack signaling power for acknowledging UE transmissions associated with larger uplink bandwidth allocations. Additionally, or alternatively, the UE is configured to bias its ARQ signal evaluations, to bias its ack/nack decision determinations to favor the ack decision, at least for those acks associated with transmissions that used greater resource allocations.
