1. A method for pipelining data retransmission, comprising:
receiving, at a wireless access point, uplink data from a user equipment (UE);
determining, at the wireless access point, that the uplink data must be retransmitted from the UE to the wireless access point; and
in response to determining that the uplink data must be retransmitted from the UE to the wireless access point:
sending at least one of buffer status information and Grant information from the wireless access point to a first communication device upstream of the wireless access point, to prepare communication infrastructure upstream of the wireless access point for retransmission of the uplink data from the UE to the wireless access point, and
instructing the UE to retransmit the uplink data to the wireless access point.
