Abstract
Systems and methodologies are described that facilitate reverse link power control on a traffic channel. Indications of other sector interference or other such interference levels can be broadcasted in a wireless communication. Further, power control related information can be included in assignments to mobile devices. Mobile device can utilize the information in the assignment to set a range for delta-based power control. Further, devices employ broadcasted interference indications to maintain and adjust delta values that enable power settings to be established on traffic channels. Moreover, mobile devices may provide feedback to facilitate future assignments.
Claims28
A method that facilitates reverse link traffic channel power control, comprising:
- providing, by an apparatus, power control information in an assignment, wherein the power control information includes a minimum carrier-over-thermal (CoT) value and a maximum CoT value;
- broadcasting, by the apparatus, an interference offset value for each subband utilized to establish an adjustment range;
- and
- broadcasting, by the apparatus, an other sector interference (OSI) indication that is employed to adjust a power control value.
A wireless communications apparatus, comprising:
- a memory that retains instructions related to providing power control information in an assignment, wherein the power control information includes a minimum carrier-over-thermal (CoT) value and a maximum CoT value, broadcasting interference offset values for each subband, broadcasting regular other sector interference (OSI) parameters and broadcasting fast OSI parameters;
- and
- a processor coupled to the memory, configured to execute the instructions retained in the memory.
A wireless communications apparatus that facilitates delta-based power control, comprising:
- means for providing power control information in an assignment of a mobile device, wherein the power control information includes a minimum carrier-over-thermal (CoT) value and a maximum CoT value;
- means for broadcasting an interference offset value for each subband;
- and
- means for broadcasting an other sector interference (OSI) indication that enables delta-based power control.
A machine-readable medium having stored thereon machine-executable instructions for:
- providing power control information in an assignment, wherein the power control information includes a minimum carrier-over-thermal (CoT) value and a maximum CoT value;
- broadcasting an interference offset value for each subband utilized to establish an adjustment range;
- and
- broadcasting an other sector interference (OSI) indication that is employed to adjust a power control value.
In a wireless communication system, an apparatus comprising:
- an integrated circuit configured to:
- assign a reverse link traffic channel to a mobile device;
- provide power control related information in the assignment, wherein the power control related information includes a minimum carrier-over-thermal (CoT) value and a maximum CoT value;
- and
- broadcast regular and fast other sector interference (OSI) indications to at least one mobile device to facilitate delta-based power control.
