    Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform at least receiving, by a network device of a communication network, information providing an indication to connect to a network node of the communication network using a Random Access Channel (RACH)-less) signaling procedure; determining that connecting to the network node using the RACH-less signaling procedure has failed; and based on the RACH-less signaling procedure failing, using at least one alternative signaling procedure for connecting to the network node using uplink (UL) resources from RACH-less procedure. Further, in accordance with example embodiments of the invention there is at least a method and apparatus to perform based on a RACH-less signaling procedure from a network device failing to connect to a network node, receiving, by the network node, at least one alternative signaling procedure from the network device for the connecting; and establishing a connection with the network device based on the at least one alternative signaling procedure from the network device using the UL resources from RACH-less procedure.

    Abstract: When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.

    Abstract: A user equipment (UE) includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the UE to obtain a conditional handover command, the conditional handover command indicating a multiple cell target for handover from a source cell and at least one performance margin, each of the at least one performance margin associated with a cell neighboring a first cell in the multiple cell target, determine whether to initiate a handover to the first cell based on the at least one performance margin, and transmit data to the first cell based on the determination of whether to initiate the handover.

    Abstract: There are provided measures for feedback on network-assisted fallback to contention-based random access. Such measures exemplarily comprise, at a terminal connected to at least one network slice and being subject to a handover from a source access point to a target access point, receiving a handover command message including handover assistance information indicative of a first pool of random access channel resources to be used by said terminal upon fallback to contention-based random access during a handover processing, selecting first random access channel resources as attempt random access channel resources from said first pool of random access channel resources, attempting random access to said target access point utilizing said attempt random access channel resources, storing, if said attempting random access to said target access point utilizing said attempt random access channel resources is unsuccessful, attempt related information to an attempt failure list, and transmitting, if said attempting random access to said target access point utilizing said attempt random access channel resources is successful, said attempt failure list to said target access point.

    CPC classification number: H04W36/0072

    Abstract: Aspects of the present invention pertain to a method, comprising receiving a preparatory handover request pertaining to at least one or more physical resources, respectively associated to a particular communication service, preliminarily deciding on the feasibility of such preparatory handover request for each of said at least one or more physical resources associated to the particular communication service dependent on at least one feasibility criterion, and validating the preliminary decision on the feasibility of the preparatory handover request dependent on at least one validation criterion. Likewise, corresponding apparatus and computer program products are addressed, both from network entity perspective such as a gNB, as well as from a terminal's perspective, e.g. from a UE perspective.
