An apparatus is disclosed for multiplexing radar beat signals. In an example aspect, the apparatus includes an antenna array and a wireless transceiver jointly configured to transmit a radar transmit signal and receive two or more radar receive signals. The two or more radar receive signals represent portions of the radar transmit signal that are reflected by an object. The wireless transceiver comprises a radio-frequency integrated circuit with two or more receive chains and a multiplexing circuit. Each one of the two or more receive chains is configured to generate a radar beat signal by downconverting a respective radar receive signal of the two or more radar receive signals using the radar transmit signal. The multiplexing circuit is coupled to the two or more receive chains and is configured to multiplex the two or more radar beat signals together to generate a composite radar beat signal.

A method for operating a communication system in a communication network for optimizing a codec selection between a calling device communication network and a called device communication network is provided. The communication system is configured to receive a call set-up message from the calling device communication network (wherein the call set-up message comprises an identity of an origination codec and a called number), determine an identity of a destination codec based upon the called number, communicate the identity of the destination codec to the calling device communication network, and establish a call between the calling device communication network and the called device communication network using the destination codec.

A method for using a code division multiple access (CDMA) subscriber unit to transmit a communication to a base station at a first data rate using at least one communication channel, determine an adjusted data rate desired for support of the communication, and transmit the communication to the base station over a second channel at a second data rate, wherein the first data rate is different than the second data rate.
