Abstract: A method that comprises identifying a group of user equipment (UEs) in a radio access network, where the group includes a transmitting UE and a plurality of receiving UEs. The method further comprises sending control information including probe signal parameters to the transmitting UE and to the receiving UEs. The method also comprises receiving, from the receiving UEs, performance metrics relating to receipt of a probe signal sent by the transmitting UE based on the probe signal parameters. The method may be implemented by a scheduler. As such, based on the feedback received, the scheduler may carry out more judicious pairing of UEs for uplink and downlink transmission, which may be particularly suitable when the UEs communicate in half-duplex fashion.

Abstract: Techniques and architectures for multi-stage cancellation of self-interference (SI) and joint cancellation of mutual-interference (MI) and residual SI in signals received by devices of a full-duplex multi-cell network are disclosed. In various examples, channel estimations and interference cancellation operations are performed utilizing multiple orthogonal training signals transmitted by network devices during a common over-the-air training period. Training signals derived from the orthogonal training signals during transmission are utilized to generate SI estimation information and perform at least a first SI cancellation operation on a received signal that includes at least first and second orthogonal training signals. The received signal and orthogonal training signals are then used to estimate a MI channel impulse response and a (residual) SI channel impulse response for use in joint MI/SI cancellation operations on further received signals.

Abstract: Methods and devices for receiving or transmitting a wireless packet are described. A wireless packet includes a short training field (STF) and a channel estimation field (CEF). The receiver determines whether the received STF matches an assigned STF assigned for a target link, by performing cross-correlation between the STF and a component sequence from a set of at least four different component sequences which are pairs of Golay sequences. The cross-correlation output is compared with an expected output. When the received STF matches the assigned STF, the wireless packet is considered a target packet. A channel estimation is performed using a cross-correlation of the received CEF with an assigned CEF assigned for the target link. The assigned CEF is from a set of two or more CEFs, where each CEF is formed using the set of component sequences, and the CEFs are pairwise zero-correlation zone (ZCZ) sequences.

Abstract: A network-wide interference cancellation scheme estimates channel impulse responses related to Self Interference and the Mutual Interference, then reduces both the Self Interference and the Mutual Interference in the receiver of an Full Duplex device. Full Duplex gains may be capitalized upon and translated into system gain. The scheme is based on an extended Multiple-Input-Multiple-Output (MIMO) treatment of the whole Full Duplex network. The network-wide interference cancellation may be seen to be feasible when a unique pilot signal design and training structure are in place network-wide.
