Abstract: A network device generates a successive joint channel estimation based on interference cancellation processes to eliminate or reduce colliding interferences (colliders) at a receiver end. A selection component selects a strongest interference collider from among pseudo noise sequences operating as colliders. A 2 by 2 matrix successive joint channel estimation component performs a successive 2 by 2 matrix joint channel estimation with an initial correlation metric between the strongest interference collider and each remaining interference collider in a first iteration of a set of iterations. A correlation metric component generates an updated correlation metric vector based on the 2 by 2 matrix joint channel estimation. Another 2 by 2 matrix joint channel estimation is then performed with the updated correlation metric vector between a next strongest interference collider and remaining interference colliders of the plurality of interference colliders at a second iteration of the set of iterations.

Abstract: Embodiments of a User Equipment (UE) and methods for determination of a side-link reference signal received power (S-RSRP) are disclosed herein. The UE may receive a signal from a second UE as part of a device-to-device (D2D) communication. The UE may determine a resource element (RE) block size to be used for a determination of the S-RSRP. The RE block size may be based on a delay spread of a channel between the UE and the second UE. The UE may determine the S-RSRP based on multiple summations, sizes of which may be based on the determined RE block size.
