Claim of US Patent No. 10,602,508

1. A method of wireless communication, the method comprising:determining K subsets of a resource pool comprising time-frequency resources, the determination made by partitioning a time period of the time-frequency resources into the K subsets, each subset including K grid elements, the K grid elements formed by partitioning frequency resources of each subset into K frequency ranges, each grid element of the K grid elements including a total of K sub-elements;
selecting one subset of the K subsets of the resource pool; and
transmitting a message using K sub-elements of the selected subset, wherein a value for K is 4, wherein the time-frequency resources are divided into a 4×4 grid having 4 subsets, each subset having 4 grid elements, each grid element having 4 sub-elements, wherein each of the subelements used to transmit the message are within distinct grid elements, wherein time-frequency resources are divided into a K*K grid of floor (Nt/k) sub-frames and floor (Nf/k) resource blocks (RBs) each, where Nt is a number of sub-frames and Nf is a number of physical resource blocks (PRBs) in an available frequency bandwidth.
