Facilitating compact signaling design for reserved resource configuration in wireless communication systems

Abstract

A system facilitating compact signaling design for reserved resource configuration via a multi-dimensional bitmap is provided for a wireless communication system. A method comprises: determining a multi-dimensional bitmap (MDB) in time and frequency domains, wherein the time domain is represented by an orthogonal frequency division multiplexed (OFDM) symbol and the frequency domain is represented by an OFDM subcarrier. The determining comprises: selecting a group of reserved resource allocations of the MDB in which data information is not to be communicated; assigning a first value for the OFDM multiplexed symbol and the OFDM subcarrier according to a location of elements of the group of reserved resource allocations; and assigning, to other portions of the MDB other than the group of reserved resource allocations, a second value distinct from the first value. The method also comprises facilitating, by the device, transmitting the MDB to a mobile device.
