Abstract: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for secondary cell group (SCG) addition. A wireless device may establish communication with a first base station that is comprised a master cell group (MCG). The wireless device may receive signaling from the first base station configuring a second base station in a secondary cell group (SCG). The wireless device may establish communication with the second base station based on the signaling received from the first base station. At a first time, the wireless device may set the second base station in a deactivated state based on the signaling from the first base station configuring the second base station or establishing communication with the second base station. At a later time, the wireless device may set the second base station in an activated state and communicate with the first base station and the second base station.

Abstract: A method includes causing, at a first user equipment (UE), transmission of at least one positioning reference signal (PRS) to a second UE via a sidelink (SL) communication based on first positioning assistance data. The transmission enables the second UE to determine positioning measurements from at least part of the at least one PRS.

Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.

Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.
