Method and apparatus for receive diversity in a communication system

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

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

A method in a communication system for decoding a quick paging channel (QPCH) comprising:

• determining a channel condition of a pilot channel received at a mobile station in said communication system;
• determining receive diversity at a receiver of said mobile station by determining a number of a plurality of receiver chains of said receiver for receive diversity based on said determined channel condition;
• determining a first data bit of said QPCH received at said mobile station in accordance with processing of one or more signals produced based on said determined receive diversity.

An apparatus for decoding a quick paging channel (QPCH) in a communication system comprising:

• a receiver for determining a channel condition of a pilot channel received at a mobile station in said communication system;
• a controller for determining receive diversity at said receiver by determining a number of a plurality of receiver chains of said receiver for receive diversity based on said determined channel condition, wherein a first data bit of said QPCH received at said receiver is determined in accordance with processing of one or more signals produced based on said determined receive diversity.

A method for decoding a quick paging channel (QPCH) in a communication system comprising:

• determining a first data bit of said QPCH received at a receiver, including a plurality of receiver chains for receive diversity, in a mobile station in said communication system;
• determining receive diversity at said receiver of said mobile station when said determined first data bit is a one or an erasure.

An apparatus for decoding a quick paging channel (QPCH) in a mobile station in a communication system comprising:

• a receiver for determining a first data bit of said QPCH, wherein said receiver includes a plurality of receiver chains for receive diversity;
• a control system for determining receive diversity at said receiver when said determined first data bit is a one or an erasure.

An apparatus for decoding a quick paging channel (QPCH) in a communication system comprising:

• a receiver for determining a first data bit of said QPCH received at said receiver, wherein said receiver includes a plurality of receiver chains for receive diversity, and for determining a second data bit of said QPCH received at said receiver when said first data bit of said QPCH is either a one or an erasure;
• a control system for switching said mobile station to a sleep mode when said determined first data bit is a zero, for determining receive diversity at said receiver when said determined second data bit is an erasure based on a channel condition of pilot channel received at said receiver, and for directing said mobile station resources to receive a receive channel when said determined second data bit is a one.

An apparatus for decoding a quick paging channel (QPCH) in a communication system comprising:

• a receiver for determining a first data bit of said QPCH received at said receiver, including a plurality of receiver chains for receive diversity, in a mobile station in said communication system and determining a second bit of said QPCH received at said receiver when said first data bit of said QPCH is a one;
• a control system for switching said mobile station to a sleep mode when said determined first data bit is a zero and for determining receive diversity at said receiver of said mobile station when said determined first data bit is an erasure based on a channel condition of pilot channel received at said receiver, and wherein said receiver determines said second bit of said QPCH received at said receiver in accordance with said determined receive diversity.
