Embodiment Construction

[0022] A method for embedded encoding of at least two types of information is disclosed. Determine the type of the first encoder and the second encoder. Rates for the first encoder and the second encoder are determined. A first codeword and a second codeword are generated. A mapping rule is determined for the second codeword. An encoding rule is determined for the first codeword. The second codeword is mapped to a plurality of symbols using the mapping rule. A third codeword is determined using the first codeword, the plurality of symbols, and the encoding rule. Send the third codeword. The third codeword includes at least two types of information.

[0023] The first message and the second message may require unequal error protection. The generating step may include: encoding a first message with the first encoder; and encoding a second message with the second encoder. The first encoder may be an error correction code encoder. The second encoder may be an error correc...

Abstract

A method for embedded encoding of at least two types of information is described. A first message and a second message are received. The types of a first encoder and a second encoder are determined. The rates of the first encoder and the second encoder are determined. A first codeword and a second codeword are generated. A mapping rule for the second codeword and a coding rule for the first codeword are determined. The second codeword is mapped into a plurality of symbols using the mapping rule. A third codeword is determined using the first codeword, the plurality of symbols, and the coding rule. The third codeword is then transmitted. The third codeword includes at least two types of information.

Description

technical field [0001] The present invention relates generally to wireless communication and wireless communication related technologies. More specifically, the present invention relates to systems and methods for providing unequal error protection using embedded coding. Background technique [0002] Typically, a wireless communication system includes a base station that wirelessly communicates with a plurality of user equipment (also referred to as user equipment, mobile stations, subscriber units, access terminals, etc.). The base station transmits data to the user equipment over a radio frequency (RF) communication channel. The terms "downlink" and "forward link" refer to transmissions from a base station to user equipment, while the terms "uplink" and "reverse link" refer to transmissions from user equipment to a base station. [0003] The 3rd Generation Partnership Project (3GPP) is a collaboration of standards organizations around the world. The goal of 3GPP is to d...
