Abstract

A method and apparatus for processing an AccessGrant block in a wireless communication system is provided, comprising placing the AccessGrant in a public data, adjusting timing of the sector that transmitted the AccessGrant, instructing a RCC MAC to initialize transmit power and transmitting an AccessGrantReceived indication for a sector.

Claims

1. A method of processing an AccessGrant block, for at least one sector in an active set, comprising:

receiving, at an access terminal, an AccessGrant;

making, at the access terminal, one or more determinations, wherein the one or more determinations comprise;

determining whether a carrier on which the AccessGrant was received matches an AccessCarrier in a public data of an Access Channel medium access control (MAC) protocol if multi-carrier mode is MultiCarrierOn; and

based on the one or more determinations;

placing, at the access terminal, the AccessGrant in the public data of the Access Channel MAC Protocol,

adjusting, at the access terminal, timing of a sector that transmitted the AccessGrant,

instructing, at the access terminal, a reverse control channel (RCC) MAC to initialize transmit power, and

transmitting, at the access terminal, an AccessGrantReceived indication for the sector.

2. The method as claimed in claim 1, wherein the one or more determinations further comprise:

determining whether the access terminal has an assigned MACID on the sector;

determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

3. The method as claimed in claim 1, wherein the one or more determinations further comprise:

determining whether a MACID in the AccessGrant matches a MACID assigned to the access terminal on the sector;

determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

4. A non-transitory computer-readable medium comprising codes for causing a computer to:

receive, at an access terminal, an AccessGrant;

make, at the access terminal, one or more determinations, wherein the one or more determinations comprise;

determining whether a carrier on which the AccessGrant was received matches an AccessCarrier in a public data of an Access Channel medium access control (MAC) protocol if multi-carrier mode is MultiCarrierOn; and

based on the one or more determinations;

place, at the access terminal, the AccessGrant in the public data of the Access Channel MAC Protocol,

adjust, at the access terminal, timing of a sector that transmitted the AccessGrant,

instruct, at the access terminal, a reverse control channel (RCC) MAC to initialize transmit power, and

transmit, at the access terminal, an AccessGrantReceived indication for the sector.

5. The computer-readable medium as claimed in claim 4, wherein the one or more determinations further comprise:

determining whether the access terminal has an assigned MACID on the sector;

determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

6. The computer-readable medium as claimed in claim 4, wherein the one or more determinations further comprise:

determining whether a MACID in the AccessGrant matches a MACID assigned to the access terminal on the sector;

determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

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

means for receiving, at an access terminal, an AccessGrant;

means for making, at the access terminal, one or more determinations, wherein the means for making one or more determinations comprises;

means for determining whether a carrier on which the AccessGrant was received matches an AccessCarrier in a public data of an Access Channel medium access control (MAC) protocol if multi-carrier mode is MultiCarrierOn; and

based on the one or more determinations;

means for placing, at the access terminal, the AccessGrant in the public data of the Access Channel MAC Protocol,

means for adjusting, at the access terminal, timing of a sector that transmitted the AccessGrant,

means for instructing, at the access terminal, a reverse control channel (RCC) MAC to initialize transmit power, and

means for transmitting, at the access terminal, an AccessGrantReceived indication for the sector.

8. The apparatus as claimed in claim 7, wherein the means for making one or more determinations further comprises:

means for determining whether the access terminal has an assigned MACID on the sector;

means for determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data, of Access Channel MAC protocol; and

means for determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

9. The apparatus as claimed in claim 7, wherein the means for making one or more determinations further comprises:

means for determining whether a MACID in the AccessGrant matches a MACID assigned to the access terminal on the sector;

means for determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

means for determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

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

a processor;

memory in electronic communication with the processor; and

instructions stored in the memory, the instructions being executable by the processor to;

receive, at an access terminal, an AccessGrant;

make, at the access terminal, one or more determinations, wherein the one or more determinations comprise;

determining whether a carrier on which the AccessGrant was received matches an AccessCarrier in a public data of an Access Channel medium access control (MAC) protocol if multi-carrier mode is MultiCarrierOn; and

based on the one or more determinations;

place, at the access terminal, the AccessGrant in the public data of the Access Channel MAC Protocol,

adjust, at the access terminal, timing of a sector that transmitted the AccessGrant,

instruct, at the access terminal, a reverse control channel (RCC) MAC to initialize transmit power; and

transmit, at the access terminal, an AccessGrantReceived indication for the sector.

11. The apparatus of claim 10, wherein the one or more determinations comprise:

determining whether the access terminal has an assigned MACID on the sector;

determining whether an AccessSequenceID used to scramble the AccessGrant matches the AccessSequenceID in the public data of Access Channel MAC protocol; and

determining whether a PilotPN of the sector that transmitted the AccessGrant matches the PilotPN in the public data of Access Channel MAC protocol.

12. The apparatus of claim 10, wherein the one or more determinations comprise:

determining whether a MACID in the AccessGrant matches a MACID assigned to the access terminal on the sector;
