Method and apparatus for low-overhead packet data transmission and control of reception mode
First Claim
1. A method for wireless communications comprising:
- receiving, at a user equipment, a control packet comprising information related to a previously transmitted data packet;
receiving, at the user equipment, a retransmission data packet, wherein the previously transmitted data packet and the retransmission data packet are derived from common data at a remote device; and
recovering, at the user equipment, the common data based on the information related to the previously transmitted data packet, wherein the previously transmitted data packet and the retransmission data packet are associated with a sequence of data packets comprising a first data packet and wherein the first data packet does not have a control packet associated therewith.

Abstract
A method for wireless communications where a control packet is not transmitted for all transmissions of a new data packet. A control packet is only sent with a retransmission of a data packet where the previously transmitted data packet is not completely received. The control packet contains information related to a previously transmitted data packet. The previously transmitted data packet and the retransmission data packet are derived from common data. The common data is derived based on the information related to the previously transmitted data packet, wherein the previously transmitted data packet and the retransmission data packet are associated with a series of data packets.
