Abstract
A data frame format, and method for forming a data frame for use in a wireless communication system, which includes both voice and command/control data in each frame. The data frame has two or more voice fields and two or more command fields. Each of the voice fields are equal in size and contain an equal portion of the digital audio data. The voice fields may be further arranged into two or more sub-portions arranged most significant to least significant bit and each of the sub-portions are arranged most significant to least significant bit. The voice fields may further include a check field contiguous to one of the two or more sub-portions to provide the ability to determine whether a selected portion of each of the sub-portions is erroneous. Each of the command fields contain an equal portion of the digital command data. Each of the two or more command fields are interleaved between the two or more voice fields and contiguous to at least one of the two or more voice fields in the data frame. The data frame may also include a frame synchronization field.
