Abstract
To address the need for an interference-efficient method and apparatus to provide CDMA services, embodiments of the present invention adjust the outer loop frame error rate (FER) target on the forward and reverse links (110-113) while providing communication services to remote units (101-102). At times during a service when a link is conveying primarily “empty” eighth rate frames, the FER target for that link is increased. This improves system capacity by effectively reducing the power needed to transmit such frames and thereby reducing the resultant interference.
Claims18
An interference-efficient method for a radio access network (RAN) to provide communication services to a remote unit in a code division multiple access (CDMA) system, the method comprising:
- establishing a communication channel with the remote unit, wherein the communication channel includes a CDMA forward link and a CDMA reverse link;
- while the remote unit is in a speaking mode, targeting a first frame error rate (FER) level for the reverse link through power control signaling;
- and
- while the remote unit is in a non-speaking mode, targeting a second FER level for the reverse link through power control signaling, wherein the second FER level is greater than the first FER level.
A radio access network (RAN) comprising:
- a transmitter;
- a receiver;
- and
- a controller, coupled to the transmitter and the receiver, adapted to establish a communication channel with the remote unit using the transmitter and the receiver, wherein the communication channel includes a CDMA forward link and a CDMA reverse link, adapted to target a first frame error rate (FER) level for the reverse link through power control signaling while the remote unit is in a speaking mode, and adapted to target a second FER level for the reverse link through power control signaling while the remote unit is in a non-speaking mode, wherein the second FER level is greater than the first FER level.
