Method and apparatus for determining receive diversity in mobile station

An apparatus for determining receive diversity in a communication system, comprising:

• a control system for determining a demand level associated with system capacity of said communication system;
• and
• a transmitter for communicating a message indicating use of receive diversity at a mobile station, said message based on said determined demand level, wherein said message indicates at least one of reducing a scale and turning off use of receive diversity at said mobile station when said demand level is lesser than a predetermined level.

An apparatus for determining receive diversity in a communication system, comprising:

• a control system for determining a demand level associated with system capacity of said communication system;
• and
• a transmitter for communicating a message indicating use of receive diversity at a mobile station, said message based on said determined demand level, wherein said message indicates at least one of increasing scale and turning on use of receive diversity at said mobile station when said demand level is higher than a predetermined level.

An apparatus for determining receive diversity in a communication system, comprising:

• a receiver, including a plurality of receiver chains, for receiving a channel and determining a channel condition of said channel and duration of said channel condition;
• and
• a control system for controlling receive diversity of said receiver by selecting a number of said plurality of receiver chains based on said determined channel condition and said duration.

A method for determining receive diversity in a communication system, comprising:

• determining a channel condition of a channel received at a receiver, including a plurality of receiver chains, and duration of said channel condition;
• and
• controlling receive diversity of said receiver by selecting a number of said plurality of receiver chains based on said determined channel condition and said duration.

The method as recited in claim further comprising:

• reducing said number of selected receiver chains when said determined channel condition is above a disable-receive-diversity threshold and said determined duration is longer than a receive-diversity-disable period threshold and increasing said number of selected receiver chains when said determined channel condition is below an enable-receive-diversity threshold and said determined duration is longer than a receive-diversity-enable period threshold, wherein said disable-receive-diversity threshold corresponds to a stronger channel condition than a channel condition corresponding to said enable-receive-diversity threshold.

A computer readable medium embodying instructions executable by a processor to perform a method comprising:

• determining a demand level associated with system capacity of a communication system;
• and
• communicating a message indicating use of receive diversity at a mobile station, said message based on said determined demand level, wherein said message indicates at least one of reducing a scale, turning off, turning on and increasing scale of receive diversity at said mobile station.
