METHODS AND SYSTEMS FOR PROCESSING OVERHEAD REDUCTION FOR CONTROL CHANNEL PACKETS
First Claim
Patent Images
1. A method for receiving information from an access point over a wireless link, comprising:
- wirelessly receiving a packet containing information;
processing the received packet using at least a descrambling operation on at least a portion of the information based on a first identifier associated with an access terminal to produce at least a first processed packet; and
determining whether the received packet is targeted to the access terminal based on the first processed packet.

Abstract
Various methods and systems receiving information from an access point over a wireless link in order to reduce processing and/or transmission overhead are disclosed. Such methods and systems may include the processing of a received packet using a descrambling operation on at least a portion of the packet'"'"'s information based on a MAC-ID associated with an access terminal to produce at least a first processed packet, and determining whether the received packet is targeted to the access terminal based on the first processed packet.

23. A computer-readable memory containing a plurality of instructions that, when accessed by a computer, enables the computer to perform the steps of:
-
processing a received packet using at least a descrambling operation on at least a portion of the information based on a first identifier associated with an access terminal to produce at least a first processed packet; and
determining whether the received packet is targeted to the user based on the first processed packet. - View Dependent Claims (24, 25, 26, 27, 28, 29)

30. A system for receiving information from an access point over a wireless link, comprising:
a media access controller (MAC) with a processing circuit and a memory in communication with the processing circuit, wherein the MAC is configured to process a wirelessly received packet to determine whether the wirelessly received packet is directed for use by the system by performing a descrambling operation on at least a portion of the received packet using a MAC identification (MAC-ID) associated with the MAC as a descrambling key. - View Dependent Claims (31, 32, 33, 34)

35. A system for receiving information from an access point over a wireless link, comprising:
-
a computer-readable memory; and
a determining means in communication with the memory for determining whether a packet residing in the memory is intended for use with the system based on a descrambling operation on at least a portion of the packet using a specific Media Access Controller Identifier (MAC-ID). - View Dependent Claims (36, 37, 38, 39)

40. A method for transmitting information to an access terminal over a wireless link, comprising:
-
processing a first packet containing information by applying at least a scrambling operation on at least a portion of the information using a logical address associated with an intended access terminal to produce at least a first processed packet; and
wirelessly transmitting the processed packet to a plurality of access terminals. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47)
