Abstract

Methods and apparatus related to partitioning traffic segments are described. An access router, having concurrent connections with two access terminals, each desiring to transmit traffic signals to the access router in the same traffic segment, partitions a traffic segment. The partition is such that a first portion of the traffic segment is allocated to a first access terminal and a second portion of the traffic segment is allocated to the second access terminal. Control information, e.g., conveying partition information, is communicated to access terminals prior to the traffic segment. In some embodiments, the partition information is communicated as part of a transmission request response signal, e.g., via phase of the request response signal. An access terminal which has been allocated a traffic segment partition portion identifies is allocation from the transmitted control information, and subsequently transmits traffic signals to the access router in its allocated portion of the traffic segment.

Claims

1. A method of operating an access terminal, the method comprising:

receiving at least one signal from an access router, said at least one signal corresponding to a first traffic segment; and

determining, at least based on said received at least one signal, a partition portion of said first traffic segment allocated to said access terminal for communicating with said access router

transmitting traffic data in the partition portion of said first traffic segment determined to be allocated to said access terminal

wherein said at least one signal is one of a plurality of transmission request responses corresponding to said first traffic segment that are transmitted by said access router; and

wherein determining a partition portion of said first traffic segment allocated to said access terminal includes determining a partition portion based on a total number of transmission request responses received from said access router which correspond to said first traffic segment.

2. The method of claim 1, wherein said at least one signal is an assignment signal indicating partition assignment to the access terminal.

3. A method of operating an access terminal, the method comprising:

receiving at least one signal from an access router, said at least one signal corresponding to a first traffic segment; and

determining, at least based on said received at least one signal, a partition portion of said first traffic segment allocated to said access terminal for communicating with said access router

transmitting traffic data in the partition portion of said first traffic segment determined to be allocated to said access terminal

wherein determining a partition portion of said first traffic segment allocated to said access terminal includes;

detecting a phase of said at least one signal; and

determining from the detected phase the partition portion of said first traffic segment allocated to said access terminal.

4. The method of claim 3, wherein there are a number of predetermined fixed partition options, the detected phase indicating one of said predetermined fixed partition options.

5. The method of claim 4, wherein said at least one signal is a transmission request response signal.

6. An access terminal comprising:

at least one processor configured to;

receive at least one signal from an access router, said at least one signal corresponding to a first traffic segment; and

determine, at least based on said received at least one signal, a partition portion of said first traffic segment allocated to said access terminal for communicating with said access router; and

memory coupled to said at least one processor wherein said at least one processor is further configured to transmit traffic data in the partition portion of said first traffic segment determined to be allocated to said access terminal

wherein said at least one signal is one of a plurality of transmission request responses corresponding to said first traffic segment that are transmitted by said access router; and

wherein said at least one processor is further configured to determine a partition portion of said first traffic segment allocated to said access terminal includes determining a partition portion based on a total number of transmission request responses received from said access router which correspond to said first traffic segment.

7. The access terminal of claim 6, wherein said at least one processor is further configured to:

detect a phase of said at least one signal; and

determine from the detected phase the partition portion of said first traffic segment allocated to said access terminal.

8. The access terminal of claim 7, wherein there are a number of predetermined fixed partition options, the detected phase indicating one of said predetermined fixed partition options.

9. The access terminal of claim 8, wherein said at least one signal is a transmission request response signal.

10. The access terminal of claim 6, wherein said at least one signal is an assignment signal indicating partition assignment to the access terminal.

11. An access terminal comprising:

means for receiving at least one signal from an access router, said at least one signal corresponding to a first traffic segment; and

means for determining, at least based on said received at least one signal, a partition portion of said first traffic segment allocated to said access terminal for communicating with said access router and

means for transmitting traffic data in the partition portion of said first traffic segment determined to be allocated to said access terminal

wherein said at least one signal is one of a plurality of transmission request responses corresponding to said first traffic segment that are transmitted by said access router; and

wherein said means for determining a partition portion of said first traffic segment allocated to said access terminal includes means for determining a partition portion based on a total number of transmission request responses received from said access router which correspond to said first traffic segment.

12. The access terminal of claim 11, wherein said means for determining a partition portion of said first traffic segment allocated to said access terminal includes:

means for detecting a phase of said at least one signal; and

means determining from the detected phase the partition portion of said first traffic segment allocated to said access terminal.

13. The access terminal of claim 12, wherein there are a number of predetermined fixed partition options, the detected phase indicating one of said predetermined fixed partition options.

14. The access terminal of claim 13, wherein said at least one signal is a transmission request response signal.

15. A computer program product comprising:

a computer readable medium comprising;

code for causing at least one computer to receive at least one signal from an access router, said at least one signal corresponding to a first traffic segment; and

determining, at least based on said received at least one signal, a partition portion of said first traffic segment allocated to said access terminal for communicating with said access router

code for causing at least one computer to transmit traffic data in the partition portion of said first traffic segment determined to be allocated to said access terminal

wherein said at least one signal is one of a plurality of transmission request responses corresponding to said first traffic segment that are transmitted by said access router; and

wherein determining a partition portion of said first traffic segment allocated to said access terminal includes determining a partition portion based on a total number of transmission request responses received from said access router which correspond to said first traffic segment.
