Provided are a data transmitting or receiving method and device for dual Transport Blocks (TBs), a transmitter and a receiver. Data to be transmitted is divided into two portions, where transport blocks TB1 and TB2 are generated respectively according to a corresponding predetermined Modulation Coding Scheme (MCS) for each portion. The TB1 is modulated into an amplitude weighted complex symbol sequence S1, and the TB2 is modulated into an amplitude weighted complex symbol sequence S2. The S1 and the S2 are superposed to generate a complex symbol sequence S3 corresponding to a new TB, where the complex symbol sequence S3 corresponding to the new TB possesses Gray properties. The new TB is transmitted to a receiver.

Topographic information and clutter information is obtained for a particular geographic area in which two or more wireless network's radio communication entities are located. The topographic information includes terrain height values for points within a particular geographic area. The clutter information includes clutter height values for at least some of the points indicative of a height of clutter located atop terrain within the particular geographic area. A plurality of high-fidelity obstruction height values are determined for sampled points. Each of the sampled points are located between a first network entity and a second network entity. Critical points are identified from the sampled points based on the plurality of high-fidelity obstruction height values. Propagation information indicative of a predicted degree of interference between the two network's entities is generated based on the one or more critical points.

Systems and methods may use proximate communication to retrieve information pertaining to a target device. In one example, the method may include detecting the target device within a vicinity of a user device, receiving an information request response communication including information pertaining to the target device, and receiving an operation request response communication including information pertaining to a performed operation.
