Abstract: According to an aspect, a source node determines (1002) that a UE served by the source node is a candidate for conditional handover configuration. The source node sends (1004), to a target node for conditional handover of the UE, a conditional handover request that includes one or more parameters indicative of a likelihood that handover of the UE to the target node will be executed. The target node receives (1102) the request and parameters and allocates (1104) resources for the UE, taking into account the likelihood that handover of the first UE to the target node will be executed. The target node sends (1106) handover configuration information for the first UE to the source node, in response to the conditional handover request.

In some embodiments, a method performed by a wireless device for tuning one or more parameters of a network comprises obtaining a configuration for CO measurement and reporting. The method also includes obtaining a plurality of CO measurements based on the obtained configuration for CO measurement and reporting.

The UE, the source access node and 5the target access node are operating in a wireless communications network. The UE receives (601) a handover command message from the source access node. The UE establishes (602) a target radio connection with the target access node, and determines (603) whether or not a source cell release criterion is fulfilled. When the source cell release criterion is determined to be fulfilled, the UE releases (604) a source radio 10connection with the source access node.

Abstract: A base station or other network node configures a network transmission in dependence on a directional scanning reception ability of a wireless communication device targeted by the transmission. An example transmission configuration is selecting or restricting which Transmission/Reception Point to use for the transmission or selecting or restricting the beamforming configuration to use for the transmission. The device complements operations in the wireless communication network by indicating its directional scanning reception ability in initial signaling, such as used for random access, or in Radio Resource Control signaling, or both.

Abstract: A process allows a UE to acquire an SEN before accessing a target base station/node during a RACH-less handover. The SEN may be provided to the UE in various ways. For example, the SEN may be provided as part of a handover command message (e.g., RRCReconfiguration) or a master information block (MIB). In this manner, the UE acquires the SEN before accessing the target base station/node, which allows the target base station/node and the UE to effect certain timings for the handover. For example, the target base station/node and the UE may set time bounds in which the handover must occur. As another example, different types of uplink grants may be set.

Abstract: After receiving a handover command (22) that commands a wireless device (16) to perform a make-before-break handover (24), the wireless device (16) continues to receive from a source link (20-0) downlink data packets for an unacknowledged mode bearer (21), until after the wireless device (16) establishes a connection with the target link (20-1) as part of the handover. After the wireless device (16) establishes the connection with the target link (20-1), the wireless device (16) receives from the target link (20-1) downlink data packets for the unacknowledged mode bearer (21). The wireless device (16) preserves a downlink data packet sequence number receiver status for the unacknowledged mode bearer (21), by using the same downlink data packet sequence number receiver status for the unacknowledged mode bearer (21) before and after the handover.
