Systems and techniques are provided for wireless communications. For example, a process can include transmitting, to a network entity, first channel map information of a wireless communication device, wherein the first channel map information includes one or more channels associated with the wireless communication device. A process can include receiving, from the network entity, an identifier of a particular subframe of a plurality of subframes and a subframe channel map of the particular subframe, wherein the wireless communication device is allocated to the particular subframe based on a comparison of the one or more channels included in the first channel map information and one or more channels included in the subframe channel map of the particular subframe. A process can include transmitting, to the network entity, a periodic advertisement (PA) response using a channel included in the subframe channel map of the particular subframe.
