    Abstract: Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to transceivers and receivers for wireless communications are described. The various aspects include an apparatus of a communication device including an antenna array and processing circuitry coupled to the antenna array. The processing circuitry is configured to initialize a beam tracking algorithm based on received signals received at the antenna array, wherein antenna phases used in the beam tracking are bound by an upper phase limit and a lower phase limit, to generate a beam tracking result. The processing circuitry is further configured to generate a calibration vector based on the beam tracking result and receive subsequent transmissions using a codebook adapted based on the calibration vector.

    Abstract: A method for self-interference cancellation in a wireless communication device. The wireless communication device has an estimator, a transmitter and a cancellation device. The estimator is configured to estimate a known signal received from a second wireless communication device when the second wireless communication device is utilized less than a predetermined threshold. The transmitter is configured to transmit within a coherence time of the estimated known signal, a predetermined signal. The cancellation device is configured to cancel the estimated known signal from a received signal.

    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed for private network mobility management. An example private network in a box includes interface circuitry to communicate with multi-access terrestrial network (TN) nodes and non-terrestrial network (NTN) nodes, machine readable instructions, and programmable circuitry. The example programmable circuitry is to generate a first mesh associated with a geographical area of the private network and a second mesh associated with the geographical area. The example programmable circuitry is also to initiate at least one of the multi-access TN nodes in alignment with the first mesh and at least one of the NTN nodes in alignment with the second mesh. Additionally, the example programmable circuitry is to facilitate communication associated with at least one user equipment within at least one of the first mesh or the second mesh using the private network.

    Abstract: A Spatial Multiple Access Uplink for Wireless LANs is generally described herein. A novel FD-MiMAC, protocol leverages full duplex functionality at the Access Point, can be incrementally deployed with current 802.11 Access Point and client devices, can be easily implemented by client devices in a distributed and contention based manner, and pairs users in uplink MU-MIMO to enhance system performance. A method for spatial multiple access uplink in a wireless local area network comprises announcing, by an Access Point (AP), its available remaining antenna capability, receiving, by the AP, a packet header frame transmitted by a winning client uplink contender, allocating, by the AP, uplink resources for the winning client uplink contender and immediately announcing its remaining antenna capability, and transmitting, by the AP, at the end of a winning client's transmission burst, an Acknowledge-to-All frame, whereby other clients may simultaneously restart contention for transmission of next frames.
