Examples provide for computer executable instructions executable by a processor to configure the processor to determine an occupancy status of cells of a region of interest by, for a first cell of the region of interest, determining whether the first cell is free by setting a free space flag for the first cell to an asserted value and setting a free space tested flag for the first cell to an asserted value responsive to determining that the first cell and each of the surrounding cells in the programmed radius of the first cell are unoccupied, and setting a free space flag for a second cell to a de-asserted value and setting a free space tested flag for the second cell to an asserted value responsive to determining that the second cell is occupied, the second cell being among the surrounding cells in the programmed radius of the first cell.

Free space detection and park-able free space detection for occupancy grids using sensor measurements

A method for communicating over a wireless backhaul channel comprising generating a radio frame comprising a plurality of time slots, wherein each time slot comprises a plurality of symbols in time and a plurality of sub-carriers in a system bandwidth, broadcasting a broadcast channel signal comprising a transmission schedule to a plurality of remote units in a number of consecutive sub-carriers centered about a direct current (DC) sub-carrier in at least one of the time slots in the radio frame regardless of the system bandwidth, and transmitting a downlink (DL) control channel signal and a DL data channel signal to a first of the remote units, wherein the DL data channel signal is transmitted by employing a single carrier block transmission scheme comprising a Discrete Fourier Transform (DFT) spreading for frequency diversity.

NLOS wireless backhaul downlink communication

A method for uplink (UL) wireless backhaul communication at a wireless backhaul remote unit in a radio access network comprising receiving a configuration for radio frames and a transmission schedule through a downlink (DL) physical layer broadcast channel, wherein the transmission schedule comprises a transmission allocation for the remote unit, generating a UL data frame, wherein generating the UL data frame comprises performing forward error correction (FEC) encoding on a data bit stream to generate a plurality of FEC codewords, wherein performing the FEC encoding comprises performing Reed Solomon (RS) encoding on the data bit stream to generate a plurality of RS codewords, performing byte interleaving on the RS codewords, and performing Turbo encoding on the byte interleaved RS codewords to generate one or more Turbo codewords, wherein each Turbo codeword is encoded from more than one RS codeword, and transmitting the UL data frame according to the transmission allocation.
