Method and apparatus for full rate erasure handling in CDMA
View Patent ↗A method of processing signals received from an electronic device ( 106, 202 ) in a cellular network ( 100, 200 ) that utilizes variable rate vocoding comprising receiving a first series of low rate frames ( 318 ) at the cellular network; receiving a high rate frame ( 320 ) that has at least one bit error at the cellular network after receiving the first series of low rate frames, wherein the rate of the high rate frame can be determined; and sending a request ( 310 ) to the electronic device to retransmit the high rate frame.
1. A method of processing signals received from an electronic device in a cellular network that utilizes variable rate vocoding comprising:
receiving a first series of low rate frames at the cellular network;
receiving a high rate frame that has at least one bit error at the cellular network after receiving the first series of low rate frames, wherein the rate of the high rate frame can be determined; and
sending a request to the electronic device to retransmit the high rate frame.
2. The method of claim 1 further comprising utilizing a rate determination algorithm to determine the rate of the high rate frame.
3. The method of claim 1 wherein the high rate frame includes a Pilot Strength Measurement Message.
4. The method of claim 3 wherein the request to the electronic device to retransmit the high rate frame includes a Pilot Measurement Request Order.
5. The method of claim 1 further comprising receiving a second series of low rate frames after receiving the high rate frame.
6. The method of claim 1 further comprising making a full rate step up in an outer loop threshold in response to receiving the high rate frame.
7. A method of sending signals from an electronic device to a cellular network that utilizes variable rate vocoding comprising:
sending a first series of low rate frames to the cellular network;
sending a first high rate frame to the cellular network after sending the first series of low rate frames, wherein the rate of the first high rate frame can be determined by the cellular network and wherein the first high rate frame can not be decoded by the cellular network; and
receiving a request from the cellular network to transmit a second high rate frame, wherein the second high rate frame is a control frame and wherein the request from the cellular network is in response to the first high rate frame not being able to be decoded by the cellular network.
8. The method of claim 7 wherein the cellular network utilizes a rate determination algorithm to determine the rate of the high rate frame.
9. The method of claim 7 wherein the second high rate frame includes a Pilot Strength Measurement Message.
10. The method of claim 9 wherein the request received by the electronic device to transmit the second high rate frame includes a Pilot Measurement Request Order.
11. The method of claim 10 wherein the first high rate frame includes a Pilot Strength Measurement Message.
12. The method of claim 7 further comprising transmitting a second series of low rate frames after transmitting the first high rate frame.
13. The method of claim 7 wherein the first high rate frame includes a Pilot Strength Measurement Message.
14. An Radio Access Network (RAN) comprising:
a receiver module adapted to receive a first series of low rate frames and a high rate frame that has at least one bit error at the cellular network after receiving the first series of low rate frames;
a rate determination module adapted to determine a rate of the high rate frame; and
a rate monitoring module adapted to initiate sending a request for transmission of a high rate frame to an electronic device.
15. The RAN of claim 14 wherein the high rate frame includes a Pilot Strength Measurement Message.
16. The method of claim 15 wherein the request to the electronic device for transmission of the high rate frame includes a Pilot Measurement Request Order.
