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.

Abstract: An apparatus, method and computer program is described comprising: generating a local outage time database for a first cell of a mobile communication system, wherein the local outage time database stores first latency data for each of a plurality of devices served by the first cell, wherein each first latency data comprises time left to outage data for the respective device; sending selected parts of the local outage time database to one or more other cells of the mobile communication network; receiving second latency data from at least one of the one or more other cells of the mobile communication system, wherein said second latency data includes time left to outage data for one or more devices served by said other cells; and generating a multi-cell outage time database including some or all of the shared selected parts of the local outage time database and some or all of the received second latency data.

Abstract: According to one example embodiment, a method may include receiving, by a user equipment, at least one buffer status report configuration from a network entity. The method may further include measuring, by the user equipment, at least one uplink packet arrival time according to the received at least one buffer status report configuration. The method may further include selecting, by the user equipment, at least one buffer status report format. The method may further include transmitting, by the user equipment, at least one uplink time-stamped buffer status report to the network entity according to the selected at least one buffer status report format.
