Multimode communication and radar system resource allocation

A method comprising:

• providing transmit radar signals and transmit communication signals within frames of transmit data based on one or more predetermined parameters for transmission to M antenna elements of an array of N antenna elements;
• receiving, from the M antenna elements, frames of receive data, wherein the frames of receive data comprises receive communication signals, wherein the transmit communication signals and the receive communication signals form a communication link, and
• receiving, from L antenna elements of the array of N antenna elements different from the M antenna elements, receive radar signals, wherein the receive radar signals corresponds to the transmit radar signals, wherein N, M and L are positive integers greater than zero, and wherein M plus L is lower than or equal to N;
• allocating bandwidth for transmit radar signals and transmit communication signals within the frames of transmit data based on the one or more predetermined parameters;
• and
• changing a partitioning of the M antenna elements and the L antenna elements.

A method for operating a wireless multimode system, the method comprising:

• receiving data to be transmitted, the data comprising user communication data and radar waveforms;
• receiving information of a communication link associated with a first portion of an antenna array of the wireless multimode system;
• allocating bandwidth of frames to be transmitted by the first portion of the antenna array between the user communication data and the radar waveforms based on the received information of the communication link;
• transmitting the frames via the first portion of the antenna array;
• receiving reflected frames via a second portion of the antenna array, the second portion being different than the first portion, the reflected frames corresponding to the transmitted frames;
• retrieving reflected radar waveforms from the received reflected frames;
• determining a location of a target based on the retrieved reflected radar waveforms;
• and
• changing a partitioning of antenna elements of the first portion of the antenna array and antenna elements of the second portion of the antenna array.
