A method is provided for use in a cooperative broadcast multi-hop network that employs broadcast flood routing and multi-hop transmission using a direct-sequence spread-spectrum (DSSS) waveform. DSSS signals are received from other nodes on different channels. ASSW is performed to detect and remove interference signals received on the different channels. MDFT analysis banks each receive a beam in the spectral domain that can be channelized to generate a channelized beam that comprises multiple spectral channels. An adaptive interference mitigation space-frequency whitener module can then be applied to remove interference and generate interference-mitigated spatial-spectral domain channels. MDFT synthesis banks can each perform a MDFT synthesis operation on one of the spatial-spectral domain channels. A multi-user RAKE receiver can then combine the interference mitigated time-domain channelized signals to generate a subset (1 . . . F) of fingers that combine components of transmissions directly received from the other nodes and multipath components of those transmissions.

In some aspects, a user equipment (UE) may receive a configuration that indicates an association between a pre-emption indication field and at least one of: a set of transmission configuration indicator (TCI) states, a set of demodulation reference signal (DMRS) ports, or a set of layers; receive downlink control information (DCI) that includes a pre-emption indication that is indicated as a set of bits in the pre-emption indication field; determine whether the UE is scheduled to receive a communication in one or more pre-empted resources indicated by the set of bits, via a component carrier associated with the pre-emption indication, and using at least one of: a TCI state included in the set of TCI states, a DMRS port included in the set of DMRS ports, or a layer included in the set of layers; and decode the communication based at least in part on the determination.

A method and apparatus of transmitting a reference signal in a wireless communication system is provided. The method includes generating a precoded reference signal or a non-precoded reference signal in accordance with a rank, and transmitting the generated reference signal. Uplink transmission using multiple transmit antennas is supported through reference signal design and related control signaling.

A communication device and method include a reconfigurable receiver that is reconfigurable between communication, ranging and radar modes. The reconfigurable receiver includes a mixer configured to mix digital samples with a carrier phase estimate signal and configured to generate in-phase digital samples based on the carrier phase estimate. The reconfigurable receiver further includes a symbol correlator configured to correlate against the in-phase digital samples and generate correlated data, and a symbol binning unit configured to bin the correlated data and generate a first order channel impulse response estimate. The reconfigurable receiver yet further includes a multiplexer configured to switch the digital samples to the symbol binning unit when the reconfigurable receiver is configured in radar mode and to switch the correlated data to the symbol binning unit when the reconfigurable receiver is configured in a ranging mode.

Optimal GMSK training sequences are generated by applying a base sequence to the in-phase component of the even samples and rotating the base sequence by 2.sup.k-1 and applying the second sequence to the quadrature component of the odd samples. Using the optimal GMSK training sequence a channel estimate can be generated. Filtering the channel estimate converts the channel impulse response to one that can be used with a non-GMSK signal e.g. PSK or QAM.
