Abstract: Methods, systems, and devices are described for improving communications of a machine type communications (MTC) device. In a method of communication, a signal to interference noise ratio (SINR) of one or more resource blocks (RBs) of a target device may be estimated by, for example, an MTC device. The MTC device may then select one or more of the RBs of the target device to be in a resource pool based at least in part on the estimated SINR. In some embodiments, the MTC device may compare the estimated SINR of the one or more RBs of the target device to a threshold SINR and select one or more RBs with an SINR less than the threshold SINR to be in the resource pool. In some embodiments, the MTC device may randomly select a resource block from the resource pool and transmit on the selected resource block.
