Abstract

A method and apparatus for transmitting and receiving an ExtendedChannelInfo message. The method comprises broadcasting the ExtendedChannelInfo message over a Forward Traffic Channel Medium Access Control (MAC); transmitting the ExtendedChannelInfo message in superframes, wherein the superframe number is divisible by N_{OMPExtendedChannelInfo}; delivering the ExtendedChannelInfo message in one superframe or in a set of consecutive superframes; and determining if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe. The ExtendedChannelInfo message is transmitted and received over a communication link.

Claims

1. A method of transmitting an ExtendedChannelInfo message in an Active state in wireless communication system, the method comprising:

broadcasting the ExtendedChannelInfo message over a Forward Traffic Channel Medium Access Control (MAC);

transmitting the ExtendedChannelInfo message in superframes, wherein the superframe number is divisible by N_{OMPExtendedChannelInfo};

delivering the ExtendedChannelInfo message in one superframe or in a set of consecutive superframes; and

determining if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe.

2. The method as claimed in claim 1, further comprising, if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe, describing a structure of superframes n+k through n+k+ValidityPeriod by the ExtendedChannelInfo message, wherein the ValidityPeriod is a field of the ExtendedChannelInfo message.

3. The method as claimed in claim 1, further comprising, if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe, describing a structure of superframes n through n+k−

1 by a last ExtendedChannelInfo message transmitted before superframe n.

4. The method as claimed in claim 1, farther comprising determining if a multi-carrier mode is MultiCarrierOn.

5. The method as claimed in claim 4, further comprising, when the multi-carrier mode is MultiCarrierOn, transmitting the ExtendedChannelInfo message on each carrier.

6. A computer readable medium including instruction stored thereon, comprising:

a first set of instructions for broadcasting an ExtendedChannelInfo message over a Forward Traffic Channel Medium Access Control (MAC);

a second set of instructions for transmitting the ExtendedChannelInfo message in superframes, wherein the superframe number is divisible by N_{OMPExtendedChannelInfo};

a third set of instructions for delivering the ExtendedChannelInfo message in one superframe or in a set of consecutive superframes; and

a fourth set of instructions for determining if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe

7. An apparatus operable in a wireless communication system, comprising:

means for broadcasting an ExtendedChannelInfo message over a Forward Traffic Channel Medium Access Control(MAC);

means for transmitting the ExtendedChannelInfo message in superframes, wherein the superframe number is divisible by N_{OMPExtendedChannelInfo};

means for delivering the ExtendedChannelInfo message in one superframe or in a set of consecutive superframes; and

means for determining if the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe

8. The apparatus as claimed in claim 7, further comprising means for describing a structure of superframes n+k through n+k+ValidityPeriod by the ExtendedChannelInfo message when the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe, wherein the ValidityPeriod is a field of the ExtendedChannelInfo message.

9. The apparatus as claimed in claim 7, further comprising means for describing a structure of superframes n through n+k−

1 by a last ExtendedChannelInfo message transmitted before superframe n when the transmission of the ExtendedChannelInfo message begins in superframe n and spans k superframe.

10. The apparatus as claimed in claim 7, further comprising means for determining if a multi-carrier mode is MultiCarrierOn.

11. The apparatus as claimed in claim 7, further comprising means for transmitting the ExtendedChannelInfo message on each carrier when the multi-carrier mode is MultiCarrierOn.

12. A method for processing an ExtendedChannelInfo message in an Active State in wireless communication system, the method comprising:

receiving the ExtendedChannelInfo message from a sector;

determining a superframe number n when an access network started ExtendedChannelInfo transmission;

determining a superframe n+k−

1 when the access network ends the transmission of ExtendedChannelInfo message;

determining if the received ExtendedChannelInfo message differs from the ExtendedChannelInfo message in public data in any field except SystemTime, SectorParametersSignature or ValidityPeriod;

generating an ExtendedChannelInfo Updated indication;

storing the ExtendedChannelInfo message, indexed by PilotPN and CarrierID, in the public data;

setting an ExtendedChannelInfoExpiryTime for the message in the public data to n+ValidityPeriod;

determining if the public data contains a SectorParameters message with the same PilotPN as the sector that transmitted the ExtendedChannelInfo message;

comparing the SectorParametersSignature in the ExtendedChannelInfo message with the SectorParametersSignature in the stored SectorParameters message;

determining if the signatures do not match; and

purging the SectorParameters message from the public data.

13. A computer readable medium including instruction stored thereon, comprising:

a first set of instructions for receiving an ExtendedChannelInfo message from a sector;

a second set of instructions for determining a superframe number n when an access network started ExtendedChannelInfo transmission;

a third set of instructions for determining a superframe n+k−

1 when the access network end the transmission of ExtendedChannelInfo message;

a fourth set of instructions for determining if the received ExtendedChannelInfo message differs from the ExtendedChannelInfo message in public data in any field except SystemTime, SectorParametersSignature or ValidityPeriod;

a fifth set of instructions for generating an ExtendedChannelInfoUpdated indication;

a sixth set of instructions for storing the ExtendedChannelInfo message, indexed by PilotPN and CarrierID, in the public data;

a seventh set of instructions for setting an ExtendedChannelInfoExpiryTime for the message in the public data to n+ValidityPeriod;

an eighth set of instructions for determining if the public data contains a SectorParameters message with the same PilotPN as the sector that transmitted the ExtendedChannelInfo message;

a ninth set of instructions for comparing the SectorParametersSignature in the ExtendedChannelInfo message with the SectorParametersSignature in the stored SectorParameters message;

a tenth set of instructions for determining if the signatures do not match; and

an eleventh set of instructions for purging the SectorParameters message from the public data.

14. An apparatus operable in a wireless communication system, comprising:

means for receiving an ExtendedChannelInfo message from a sector; and

means for determining a superframe number n when an access network started ExtendedChannelInfo transmission;

means for determining a superframe n+k−

1 when the access network ends the transmission of the ExtendedChannelInfo message;

means for determining if the received ExtendedChannelInfo message differs from the ExtendedChannelInfo message in public data in any fields except SystemTime, SectorParameters Signature or ValidityPeriod;

means for generating an ExtendedChannelInfo Updated indication;

means for storing the ExtendedChannelInfo message, indexed by PilotPN and CarrierID, in the public data;
