A user equipment (UE), which is operable in EUTRA networks and in NR networks, can perform a capability transfer procedure. The UE can compile EUTRA capabilities of the UE. The UE can further compile NR capabilities of the UE. The UE can transmit one or more UE capability information messages with the compiled EUTRA capabilities and NR capabilities to a base station in an EUTRA network, characterized in that the NR capabilities are compiled subject to a capability size limit, which corresponds to a supported size of a container in a handover message sent on an inter-RAT interface between Evolved Packet Core and 5G Core.

Methods and devices for facilitating an inter-RAT handover

A target cell for handover of a wireless device from a source cell to the target cell is provided. The target cell includes processing circuitry configured to: determine to configure the source cell as a downlink carrier aggregation secondary cell, DL CA SCell, for the wireless device, and cause transmission of an indication to the source cell to at least one of: temporarily retain, after the handover, at least a portion of information specific to the wireless device; and transmit the at least the portion of information specific to the wireless device to the target cell. The indication is based at least in part on the determination.

Simultaneous handover and carrier aggregation configuration

Methods, a first, and a second network node as well as a user equipment for exchange of measurement period related parameters are provided. The user equipment performs a method for measuring a measurement quantity of a secondary cell on a second carrier operated by a second radio network node. The user equipment receives, from the second radio network node, an indication indicative of the second carrier and a first parameter indicating a measurement period for measuring the measurement quantity of the secondary cell. The user equipment measures said measurement quantity on the secondary cell on the second carrier over the measurement period. The measurement period is a predefined value times the first parameter.

Exchange of parameters relating to measurement periods

A method performed by a UE for obtaining positioning assistance data from a location server, wherein the UE and the location server are operating in a wireless communications network. The UE receives a system information broadcast from a radio network node. The UE further transmits a request for positioning assistance data to the location server in case the UE does not obtain the needed positioning assistance data via the radio network node broadcast system information. The UE further obtains carrier and/or RAT information used for the positioning assistance data broadcast. The UE further reselects or is redirected to the carrier and/or RAT used for the positioning assistance data broadcast.

The present invention provides a muting configuration for reference signal (RS) transmission as a pattern defined by at least the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell () thus are differentiated from another cell by use of a different muting sequence, a different reference point, or both. Moreover, in one or more embodiments, the present invention provides for the use of a common muting sequence or reference point across cells (), with muting occasions being differentiated between cells () through use of different reference points (in the case of a common muting sequence), or through use of different muting sequences (in the case of a common reference point), or different sequences and different reference points. Such arrangements simplify the signaling needed to control or indicate the muting configuration in use in the cells of interest, provide an advantageous basis for propagating muting configurations among cells (), eliminate the need for predefined muting configurations, and the need for blind detection of muting by wireless communication apparatuses (), such as UEs.

Method and apparatus for reference time acquisition for positioning reference signals in a wireless communication network

Embodiments herein may relate to a method performed by a UE for handling communication in a wireless communication network. The UE transmits an indication to a radio network node, indicating a type of data traffic for communication of the UE, wherein the type is related to a level of performance.

Radio network node, user equipment and methods performed therein

A wireless device and a method therein for receiving positioning system information from a radio network node. The wireless device and the radio network node operate in a wireless communications network. The wireless device receives positioning system information broadcast scheduling information comprising information about positioning System Information Blocks that are comprised in a System Information message. Further, the wireless device receives an indication that a pSIB is segmented into pSIB segments. Based on the indication and on the pSI the wireless device determines whether or not the pSIB segments are scheduled via contiguous scheduling. When the pSIB segments are determined to be scheduled via contiguous scheduling, the wireless device monitors scheduled resources, retrieves the contiguously scheduled pSIB segments and decodes position system information of the retrieved pSIB segments.

Radio network node, a wireless device and methods therein for transmission and reception of positioning system information

According to some embodiments, a method of signaling device capabilities for use in a wireless device comprises compiling frequency band combinations supported by the wireless device. The method further comprises compiling a set of device capabilities supported by the wireless device and assembling a capability message. The capability message includes: the frequency band combinations; combinations of the device capabilities supported by the wireless device; and for each of the one or more frequency band combinations, the capability message includes a first indication of one or more device capabilities supported by the frequency band combination. The first indication of the device capabilities supported by the frequency band combination comprises, for each band of the plurality of frequency bands, an indication of one of the one or more combinations of the device capabilities supported by the band when used in combination with the other bands in the frequency band combination.

UE baseband capability signaling

In a process for adding a base station as a secondary base station, and for example in 5 response to a UE Context Setup Request or a UE Context Modification Request, a distributed unit of a base station selects a feature set, and informs a central unit of the base station of the selected feature set.
