Abstract: A method and apparatus may include receiving a time-alignment value for a time-alignment timer. The method may also include starting the time-alignment timer. The method may also include transmitting one or more uplink transmissions. The uplink transmission is transmitted while the time-alignment timer is running. The method may also include receiving an updated time-alignment while the time-alignment timer is running, if the timing of the uplink transmission is determined to be correct. The method may also include applying the updated time-alignment, if the updated time-alignment is received. The method may also include stopping uplink transmissions, if no updated time alignment is received.

Abstract: A technique may include determining, by the ultra low latency user device, a decoder matrix; receiving, by the ultra low latency user device, control information indicating that a scheduled transmission of an ultra low latency data block to the ultra low latency user device is co-scheduled with a transmission of a mobile broadband data block to a mobile broadband user device via a set of shared physical resource blocks using multi-user multiple-input, multiple-output (MU-MIMO); and projecting, by the ultra low latency user device, the decoder matrix of the ultra low latency user device to be substantially orthogonal with a reference spatial subspace in which a precoder matrix for the mobile broadband user device is aligned with the reference spatial subspace, to reduce interference at the ultra low latency user device caused by the transmission of the enhanced mobile broadband data block, when receiving the ultra low latency data block.

Abstract: There is provided a method comprising causing transmission of a first uplink transmission from a first user device, the first uplink transmission having a transmission time interval comprising a plurality of subframes, receiving information from a base station, the information comprising an indication to pause transmission of the first uplink transmission for N subframes, pausing transmission of the first uplink transmission for N subframes and causing, after N subframes, continued transmission of the first uplink transmission.

Abstract: A method includes receiving, by a user equipment (UE), at least a first UE identity assigned to the user equipment for a wireless network, the first UE identity associated with a first paging timing; and receiving, by the user equipment, a second UE identity that has been assigned to the user equipment at least for paging purposes that adjusts a paging timing from a first paging timing associated with the first UE identity to a second paging timing associated with the second UE identity, wherein the second paging timing is different from the first paging timing.

Abstract: Various communication systems may benefit from improved reduction of cross link interference. For example, certain embodiments may benefit from cross link interference suppression. A method, in certain embodiments, may include receiving, by a first network entity, at least one downlink precoder map from a second network entity over at least one interface. The method may also include estimating, by the first network entity, at least one basis of at least one common spatial sub-space associated with at least one, or all, identified BS-BS CLI source. In addition, the method may include for each reception associated with the first network entity, spatially projecting, by the first network entity, at least one interference rejection combining estimated interference covariance matrix into at least one orthogonal projector sub-space.
