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.
Claims54
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.
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.
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.
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).
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.
A system for transmitting information to an access terminal over a wireless link, comprising:
- a media access control (MAC) circuit configured to scramble at least a portion of information in a packet using a specific Media Access Controller Identifier (MAC-ID);
- and
- transmission circuitry for wirelessly transmitting the scrambled packet.
