Abstract: A source network apparatus (10) which provides access for a user equipment (30) to a communication network transmits (S102) a handover command to the user equipment (30), the handover command indicating a target network apparatus (20) for providing access for the user equipment (30) to the communication network, and a detach condition on when the user equipment (30) is to detach from the source network apparatus (10) after having accessed the target network apparatus (20) (S204) and received user plane data packets from the target network apparatus (20) (S205), wherein the source network apparatus (10) continues exchanging user plane data packets with the user equipment (30) (S101, S103) until the user equipment (30) detaches (S306) from the source network apparatus (10).

Abstract: An example embodiment relates to Random Access Channel, RACH, procedure, for example in the New Radio, NR. Random access procedures may be of two types, contention based CBRA and contention free, CFRA. A client device may only perform CBRA fallback when none of the reference signal received strengths, RSRPs, of the synchronization signal blocks, SSBs, which is associated with the CFRA resources is above a predefined threshold, T1. All SSBs and CSI-RS with associated CFRA resources may be below the threshold. Then, the client device may select an SSB or CSI-RS according to a predefined rule and perform CFRA when CFRA resources are associated. Devices, methods and computer programs are disclosed accordingly.

Abstract: Systems, methods, apparatuses, and computer program products for configuring Channel State Information-Reference Signal (CSI-RS) resources of neighboring cells for inter-cell mobility are provided. One method may include providing, by a network node, at least one reporting configuration to one or more user equipment. The reporting configuration is based on at least one of channel state information reference signals (CSI-RS) or synchronization signal/physical broadcast channel (SS/PBCH) blocks. The method may also include receiving at least one measurement report comprising measurement results when and as specified by the at least one reporting configuration.

Abstract: Systems, methods, apparatuses, and computer program products for configuring and/or transmitting positioning reference signals (PRS) are provided. One method may include providing, to a user equipment, configuration information (306) for determining reference points for positioning measurements (308) or for user equipment assistance measurements. The assistance information indicates a grouping of downlink reference signals for measurements and reporting.

Abstract: In accordance with an example embodiment of the present invention, a method comprising: receiving, by a user equipment, instructions based on a determination that a communication sent from the user equipment to at least one network comprising signaling to at least one network node over continuous time slots of at least one uplink connection would cause a problem with the communication; and based on the instructions, preventing by the user equipment the signaling over at least one particular time slot of the at least one uplink connection to overcome the problem, wherein the instructions are received in a recurring pattern indicating the at least one particular time slot.

Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.

Abstract: Methods and apparatus, including computer program products, are provided for conditional handovers. In some example embodiments, there may be provided a method including sending, by a first node serving a user equipment, a message to a second node, the message including an indication of whether a conditional cell change is prohibited at the second node; and receiving, by the first node, an acknowledgment in response to the message.
