Abstract

Through the use of a variable state length initialization, both the transmitter and the receiver can have control of the length of one or more initialization states. For example, a transmitter can send information, such as a message, to the receiver at the commencement of, during initialization or prior to entering a variable length initialization state. The information can specify, for example, a minimum length of an initialization state as needed by the transmitter.

Claims

1. An information storage media including information stored thereon that, in response to execution of the information, causes one or more modules of a multicarrier communication system to perform a variable state length initialization, including:

a transmission, from a first multicarrier transceiver to a second multicarrier transceiver, of information identifying a first value that is used to determine a first minimum number of multicarrier symbols;

a transmission, from the second multicarrier transceiver to the first multicarrier transceiver, of information identifying a second value that is used to determine a second minimum number of multicarrier symbols;

a selection, by the first multicarrier transceiver, of the greater of the first minimum number of multicarrier symbols and the second minimum number of multicarrier symbols; and

a transmission, from the first multicarrier transceiver to the second multicarrier transceiver, of the selected number of multicarrier symbols during an initialization state.

2. An information storage media including information stored thereon that, in response to execution by a first multicarrier transmitter, causes one or more modules of the first multicarrier transceiver in a multicarrier communication system, including the first multicarrier transceiver and a second multicarrier transceiver, to perform a variable state length initialization with the second multicarrier transceiver, including:

a transmission, to the second multicarrier transceiver, of information identifying a first value that is used to determine a first minimum number of multicarrier symbols;

a reception, from the second multicarrier transceiver, of information identifying a second value that is used to determine a second minimum number of multicarrier symbols;

a selection of the greater of the first minimum number of multicarrier symbols and the second minimum number of multicarrier symbols; and

a transmission, to the second multicarrier transceiver, of the selected number of multicarrier symbols during an initialization state.

3. An information storage media including information stored thereon that, in response to execution by a second multicarrier transceiver, causes one or more modules of the second multicarrier transceiver, in a multicarrier communication system including a first multicarrier transceiver and the second multicarrier transceiver, to perform a variable state length initialization with the first multicarrier transceiver, comprising:

a reception, from the first multicarrier transceiver, of information identifying a first value that is used to determine a first minimum number of multicarrier symbols;

a transmission, to the first multicarrier transceiver, of information identifying a second value that is used to determine a second minimum number of multicarrier symbols; and

a reception, from the first multicarrier transceiver, of a selected number of multicarrier symbols during an initialization state, wherein the selected number of multicarrier symbols is the greater of the first minimum number of multicarrier symbols and the second minimum number of multicarrier symbols.

4. A multicarrier communication system, comprising a transmitter and a receiver, wherein the transmitter and receiver are configured to cooperatively perform a variable state length initialization, wherein the variable state length initialization includes a transmission, or a reception, of a message during an initialization state, wherein the message includes a selected number of multicarrier symbols, and wherein the transmitter and the receiver are configured to cooperatively determine the selected number of multicarrier symbols.

5. A multicarrier transceiver, comprising:

a transmitter configured to cooperatively perform a variable state length initialization with a receiver, wherein the variable state length initialization comprises a transmission of a message to the receiver during an initialization state, wherein the message includes a selected number of multicarrier symbols, and wherein the transmitter is further configured to determine the selected number of multicarrier symbols in cooperation with the receiver.

6. A method of initialization in a multicarrier communication system, the method comprising:

selecting a number of multicarrier symbols by a transmitter of the multicarrier communication system in cooperation with a receiver of the multicarrier communication system as a part of a variable state length initialization of the transmitter and the receiver; and

transmitting during an initialization state, a message from the transmitter to the receiver, wherein the message includes the selected number of multicarrier symbols.

7. A multicarrier transceiver, comprising:

a state length determination module; and

a state length verification module configured to communicate with the state length determination module to perform a variable state length initialization, wherein the variable state length initialization includes a transmission, or a reception, of a message during an initialization state, wherein the message includes a selected number of multicarrier symbols, and wherein the state length determination module is configured to determine the selected number of multicarrier symbols.

8. An information storage medium, comprising:

instructions that, in response to execution by a transmitter, cause the transmitter to perform a variable state length initialization with a receiver, wherein the variable state length initialization comprises a transmission of a message to the receiver during the initialization state, wherein the message includes a selected number of multicarrier symbols, and wherein execution of the instructions further causes the transmitter to determine the number of multicarrier symbols in cooperation with the receiver.

9. The information storage medium of claim 8, wherein the variable state length initialization further comprises another transmission of another message during another initialization state, wherein the other message includes another selected number of multicarrier symbols, and wherein execution of the instructions further causes the transmitter to determine the other selected number of multicarrier symbols in cooperation with the receiver.

10. An apparatus, comprising:

means for selecting a number of multicarrier symbols in cooperation with a receiver of a multicarrier communication system as a part of a variable state length initialization of the transmitter and the receiver; and

means for transmitting during an initialization state, a message to the receiver, wherein the message includes the selected number of multicarrier symbols.
