Mobile subscriber information transmission over multiple uplink frames
View Patent ↗Methods and apparatuses of a mobile subscriber transmitting information to a base station are disclosed. One method includes identifying an uplink transmission condition. If the uplink transmission condition is identified, the mobile subscriber transmits a message over multiple uplink frames using multiple uplink frame types. The mobile subscriber may inform the base station that it is transmitting the message over the multiple uplink frames.
1. A method for transmitting information, the method comprising:
transmitting a first portion of a message over one or more first uplink sub-frames from among a plurality of uplink sub-frames, the one or more first uplink sub-frames being of a first type including an uplink sub-frame duration and a downlink sub-frame duration;
identifying an uplink transmission condition;
adjusting, when the uplink transmission condition meets a predetermined condition, the uplink sub-frame duration and the downlink sub-frame duration to provide a second type that has a substantially similar duration as the first type; and
transmitting a second portion of the message over one or more second uplink sub-frames from among the plurality of uplink sub-frames, the one or more second uplink sub-frames being of the second type.
2. The method of claim 1 , wherein the identifying the uplink transmission condition comprises identifying an uplink quality as determined by a carrier to interference plus noise measurement.
3. The method of claim 1 , wherein the identifying the uplink transmission condition comprises:
identifying a subscriber link quality, and wherein the transmitting the second portion of the message comprises:
transmitting, based on the subscriber link quality, the second portion of the message without base station scheduling.
4. The method of claim 1 , further comprising:
receiving, from a base station, a second message to transmit the second portion of the message.
5. The method of claim 1 , further comprising:
transmitting a third portion of the message over one or more third uplink sub-frames from among the plurality of uplink sub-frames after transmitting the second portion of the message, the one or more third uplink sub-frames being of the first type.
6. The method of claim 1 , wherein the second type comprises:
a zero duration downlink sub-frame.
7. The method of claim 1 , wherein the transmitting the second portion of the message comprises:
adapting a rate of transmitting the second portion of the message according to the uplink transmission condition.
8. The method of claim 1 , further comprising:
informing a base station that the message is being transmitted over the plurality of uplink sub-frames.
9. The method of claim 1 , further comprising:
receiving an assignment of a subscriber to either a first group or to a second group, wherein the first group corresponds to the first type and the second group corresponds to the second type.
10. The method of claim 1 , further comprising:
allocating a ratio of the downlink sub-frame duration to the uplink sub-frame duration based on a bandwidth of a channel between a subscriber and a base station.
11. The method of claim 1 , wherein the adjusting further comprises:
adjusting a ratio of the downlink sub-frame duration to the uplink sub-frame duration based on the uplink transmission condition.
12. The method of claim 1 , wherein the transmitting the first portion of the message comprises:
transmitting the first portion of the message utilizing only a carrier at different instances in time.
13. The method of claim 1 , wherein the transmitting the first portion of the message and the transmitting the second portion of the message utilizes time-division duplexing (TDD).
14. A system for transmitting information, the system comprising:
a transmitter configured to transmit a first portion of a message over one or more first uplink sub-frames from among a plurality of uplink sub-frames, the one or more first uplink sub-frames being of a first type including a first uplink sub-frame duration; and
a processor configured to:
identify an uplink transmission condition;
determine whether the uplink transmission condition meets a predetermined condition; and
adjust, when the uplink transmission condition meets the predetermined condition, the first uplink sub-frame duration to a second uplink sub-frame duration to provide a frame of a second type,
wherein the transmitter is further configured to transmit a second portion of the message over one or more second uplink sub-frames from among the plurality of uplink sub-frames, the one or more second uplink sub-frames being of the second type.
15. The system of claim 14 , wherein the uplink transmission condition comprises an uplink quality as determined by a carrier to interference plus noise measurement.
16. The system of claim 14 , wherein the system includes a subscriber station comprising the processor and the transmitter.
17. The system of claim 14 , wherein the subscriber station is configured to select the frame of the second type to transmit the second portion of the message without being directed by a base station.
18. The system of claim 16 , wherein a base station directs the subscriber station to use the frame of the second type to transmit the second portion of the message.
19. The system of claim 14 , wherein the transmitter is further configured to transmit a third portion of the message over one or more third uplink sub-frames from among the plurality of uplink sub-frames after transmitting the second portion of the message, the one or more third uplink sub-frames being of the first type.
20. The system of claim 14 , wherein the second type comprises a zero duration download sub-frame.
21. The system of claim 14 , wherein the processor is further configured to adapt a rate of transmitting the second portion of the message according to the uplink transmission condition.
22. The system of claim 14 , wherein a base station is configured to assign a subscriber to either a first group or to a second group, wherein the first group corresponds to the first type and the second group corresponds to the second type.
23. The system of claim 14 , wherein the transmitter is configured to transmit the first portion of the message utilizing only a carrier at different instances in time.
24. The system of claim 14 , wherein the transmitter is configured to transmit the first portion of the message and the second portion of the message utilizing time-division duplexing (TDD).
