    Abstract: A user equipment (UE) may receive, from a first network entity, an indication of a configuration for the UE to report, to the first network entity, an estimate of a first timing advance value for a second network entity. The UE may determine the estimate of the first timing advance value. The UE may transmit, to the first network entity, the estimate of the first timing advance value for the second network entity or a reference signal time difference associated with the estimate of the first timing advance value. The UE may receive, from the first network entity, an indication of an error value associated with the estimate of the first timing advance value. The UE may determine a second timing advance value based on the estimate of the first timing advance value and the error value. The UE may transmit communications using the second timing advance value.

    Abstract: Systems, methods, apparatuses, and computer program products for user equipment autonomous resource detection for calibration are provided. For example, a method may include detecting and measuring, by a user equipment, received power during at least one synchronization signal block or channel state information reference signal. The method may also include selecting, by the user equipment, at least one random access channel occasion based on the detected and measured received power. The method may further include determining, by the user equipment, at least one random access channel occasion corresponding to the selected at least one synchronization signal block. The method may additionally include performing, by the user equipment, a user equipment calibration during the determined at least one random access channel occasion.

    Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the second access node, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

    Abstract: There is provided a method, computer program, and for an apparatus for causing an apparatus for a user equipment to perform: receiving, a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, an indication of when the first timing advance value will be invalid; using the indication of when the first timing advance value will be invalid to determine that the first timing advance value is or will soon be invalid; and determining whether to autonomously initiate obtaining a second timing advance value for the target cell in dependence on the determination of whether the first timing advance value is or will soon be invalid, the second timing advance value being obtained later in time than the first timing advance value.

    Abstract: An apparatus configured to: determine a reserved resource for a first transmission and a received signal strength associated with the reserved resource; determine, from a set of candidate resources for a second transmission, a candidate resource, wherein the candidate resource at least partially overlaps in time with the reserved resource, wherein the candidate resource does not overlap in frequency with the reserved resource; determine a relative location, in frequency, of the candidate resource with respect to at least one of: the reserved resource, a first carrier frequency associated with the first transmission, or a second carrier frequency associated with the second transmission; and exclude the candidate resource from the set of candidate resources in response to the received signal strength, associated with the reserved resource, being above a resource exclusion threshold, wherein the resource exclusion threshold is based, at least partially, on the relative location of the candidate resource.
