    Abstract: A method, apparatus, and a computer-readable storage medium are provided for a coordinated receive (or transmit) pattern during a DAPS handover. In an example implementation, the method may include a UE sending a measurement report to a first network node, the measurement report including at least a request for a time division multiplexing pattern. The method may further include receiving a radio resource control configuration from the first network node, the radio resource control configuration including at least the time division multiplexing pattern.

    Abstract: An apparatus for use by a communication element or function configured to communicate in a communication network comprising a plurality of communications cells, the apparatus comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least: to execute a handover procedure for changing a communication connection from a source cell currently serving the communication element or function to a target cell; to determine beam information indicating a communication beam of the source cell serving the communication element or function at the time when the handover procedure is executed; and to cause sending the beam information to a communication network control element or function to which the communication element is connected after the handover procedure is ended.

    Abstract: There is provided a method comprising: upon detecting that a first condition is met, causing a transmission of a measurement report to a wireless network; acquiring a conditional handover command from the wireless network; upon detecting that a second condition, associated with the conditional handover command, is met, starting a handover execution timer for triggering execution of a handover from a source cell to a target cell; detecting that a radio link failure condition is met before the execution of the handover is triggered; and on the basis of the detecting, signaling, to the wireless network, information indicative of a cause of a conditional handover failure to be either misconfigured first condition or misconfigured second condition.

    Abstract: An apparatus is configured to transmit at least one first random access request by using a first preamble to a first handover target cell or to a first beam provided by a serving cell. If the first random access request is responded, the apparatus carries out a synchronization to the first handover target cell or to the first beam provided by the serving cell. If the first random access request is not responded, the apparatus transmits at least one second random access request by using at least one second preamble to at least one second handover target cell or to at least one second beam provided by the serving cell. The apparatus stores information on not-responded first or second random access requests or resources not used for random access requests, wherein the information comprises preambles used. The apparatus transmits, after being synchronized, the stored information to either the first handover target cell, the at least one second handover target cell or the serving cell for being used in random access resource allocation.

    Abstract: There are provided measures for enabling/realizing load balancing between neighboring cells in a system with beamformed radio access. Such measures exemplarily include determining a load balancing condition, including at least one beam as a candidate beam and at least one target radio access entity for offloading terminal entities being currently served by the candidate beam, specifying a load balancing hypothesis for a hypothetical case of deactivation of the candidate beam, including information on an impact of the hypothetical beam deactivation, inquiring non-/acceptance of deactivation of the candidate beam from the at least one target radio access entity on the basis of the load balancing hypothesis, and deactivating the candidate beam if acceptance of deactivation of the candidate beam is inquired from the at least one target radio access entity.
