摘要： A wireless device (10) is configured to receive a control message (28) from a source radio network node (14S) of a handover. The control message (28) indicates a sidelink configuration (26) that is usable during and/or after the handover. Alternatively or additionally, the control message (28) indicates a sidelink configuration (26) that is supported by a target radio network node (14T) of the handover. The sidelink configuration (26) is a configuration of a sidelink (16) for the wireless device (10).

摘要： Embodiments include methods for a second radio access network (RAN) node configured to support positioning of user equipment (UEs) in the RAN. Such methods include receiving, from a UE, a request to resume the UE's connection to the RAN that is currently suspended. The request includes a first indication that UE had an ongoing positioning procedure with a first RAN node before the UE's connection to the RAN was suspended, and/or a second indication that the UE reported positioning measurements to the first RAN node before the UE's connection was suspended. Such methods include retrieving, from the first RAN node, positioning measurements made by the first RAN node during the positioning procedure and continuing the positioning procedure for the UE while the UE is connected to the RAN via the second RAN node. Other embodiments include complementary methods for the UE, the first RAN node, and a positioning node.

摘要： Embodiments include methods for a user equipment (UE) configured for positioning in a radio access network (RAN). Such methods include receiving the following from a positioning node associated with the RAN: a plurality of configurations for positioning reference signals, PRS, transmitted by the RAN, and a corresponding plurality of configuration indices associated with the plurality of configurations. Such methods include determining a need for receiving PRS, selecting one or more of the plurality of configurations based on one or more selection rules, and transmitting to the positioning node one or more requests for PRS transmission by the RAN. The one or more requests include the one or more configuration indices that are associated with the selected one or more configurations. Other embodiments include complementary methods for the positioning node and for a RAN node, as well as UEs, positioning nodes, and RAN nodes configured to perform such methods.

摘要： A radio network node (18) is configured for use in a wireless communication network (10). The radio network node (18) receives, from a location server (14), a request (16) for the radio network node (18) to report measurements usable to compute a location of a wireless device (12). The radio network node (18) transmits, to the location server (14), a message (20) that indicates the radio network node (18) is unable to report the measurements and that indicates a cause (22) of the radio network node (18) being unable to report the measurements. The cause (22) may be, for example, that the wireless device (12) has moved to another radio network node. Responsive to receiving the message (20), the location server (14) may transmit, to the other radio network node to which the wireless device (12) has moved, a request (16) for that radio network node to report measurements usable to compute a location of the wireless device (12).

摘要： Systems and methods are disclosed for User Equipment (UE) positioning for uplink grant resources. In one embodiment, a method performed by a location server includes sending one or more first New Radio Positioning Protocol Annex (NRPPa) messages to a base station that serves a target UE. Herein, the one or more first NRPPa messages include at least an expected periodical reporting of the target UE and provide priority indication associated with positioning requirements of the target UE so as to enable the base station to configure uplink grant resources. Also, the method further includes receiving, from the base station, a second NRPPa message that acknowledges a success or failure of the configured uplink grant resources.

摘要： A network node (16) is configured for use in a wireless communication network (10). The network node (16) receives one or more positioning capabilities (18) of a wireless device (12), and stores the one or more positioning capabilities (18) in storage (24) that is at or accessible to the network node (16). After storing the one or more positioning capabilities (18) of the wireless device (12), the network node (16) receives a positioning request (28) for the wireless device (12). Responsive to receiving the positioning request (28), the network node (16) retrieves the one or more positioning capabilities (18) of the wireless device (12) from the storage (24), and sends, to a positioning server (20) in the wireless communication network (10), a message that comprises the positioning request (28) and that includes the one or more positioning capabilities (18) retrieved from the storage (24). The wireless device operates thus proactively, by rendering available the wireless device positioning capability at the network node before the positioning request is received and allowing the network node to reply in a reduced time.

摘要： A method performed by a first network node. The first network node operates in a communications network. The method is for handling a measurement configuration. The first network node sends an indication to a second network node operating in the communications network. The indication indicates a transmission status of one or more Channel State Information-Reference Signal (CSI-RS) configurations of the first network node. The second network node receives the indication. The third network node receives another indication from the second network node. The third network node is managed by the second network node. The another indication indicates a transmission status of the one or more CSI-RS configurations of the first network node and configures the wireless device based on the received other indication.

摘要： A network node of a wireless communication network configures a wireless device to perform a positioning procedure responsive to occurrences of a defined event, and the wireless device subsequently modifies one or both the positioning measurement instructions and positioning assistance data used for performing one or more future occurrences of the positioning procedure, responsive to receiving modification signaling. Consequently, the network node avoids the signaling burden associated with configuring a new triggered or periodic procedure, while having the ability to modify the ongoing procedure to account for, for example, movements of the wireless device.

摘要： A radio network node (14) is split into a centralized unit (14A) and one or more distributed units in a radio access network (10). A distributed unit (14B) of the radio network node (14) transmits, to the centralized unit (14A), information (20) indicating that a wireless communication device (12) is a Reduced Capability, RedCap, User Equipment, UE. The information (20) may be transmitted, for example, in a RedCap Indication information element of a message transmitted to the centralized unit (14A), e.g., in INITIAL UL RRC MESSAGE TRANSFER message.

摘要： Methods and apparatuses for User Equipment (UE) context transitions in cell reselections. A method performed by a new serving network node for UE context transitions in cell reselection comprises receiving a Radio Resource Control (RRC) connection resume message from the UE. The method further comprises transmitting a retrieve UE context request to a last serving network node, requesting the retrieval of the UE access stratum context, and receiving a response from the last serving network node to the retrieve UE context request.
