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: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

Abstract: A base station of a network is configured to transmit a first indication to a user equipment (UE) of a mapping of code points, wherein each code point maps to one or more corresponding aperiodic or semi-persistent positioning reference signals (PRS) to be transmitted from one or more transmission and reception points (TRP), transmit a second indication to the UE of a first one of the mapped code points to activate the one or more corresponding PRSs for reception at the UE and transmit the one or more activated PRSs to the UE.

Abstract: A location management function (LMF) of a network provides timing errors to user equipment and/or base stations for positioning purposes. The LMF receives an indication of an effective timing error for a downlink time difference of arrival (DL-TDOA) positioning technique, wherein the effective timing error is associated with a set of base stations configured to transmit positioning reference signals for the DL-TDOA and provides the effective timing error to a user equipment (UE) performing operations related to the DL-TDOA.

Abstract: A user equipment (UE) is configured to decode a system information block (SIB). The UE receives a first signal, wherein the first signal includes a first individual system information block (SIB) segment of a SIB, receives a second signal, wherein the second signal includes a second individual SIB segment of the SIB, reassembles the SIB using first SIB segment and the second SIB segment and decodes the contents of the SIB.

Abstract: The exemplary embodiments relate to a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. A user equipment (UE) enters into a first state including one of a non-dormant state or a dormant state with a secondary serving cell (SCell) of a network, the SCell being configured to provide either one of a non-dormant bandwidth part (BWP) as a secondary component carrier (SCC) in the non-dormant state or a dormant BWP as an SCC in the dormant state. The UE switches from the first state to a second state including the other one of the non-dormant state or the dormant state, the switch being based on network configuration, a dormancy timer, or a radio condition.

Abstract: An approach for wireless communications to support reduced capability New Radio (NR) with larger available control resource sets (CORESET) bandwidths. Examples include a frequency-hopping CORESET with a predefined hopping pattern configured by higher layers, such as RRC signaling or MAC Control Element (CE) on a per CORESET per UE or purely per UE basis. Frequency hopping patterns for CORESET transmissions include the use of PRBs for CORESETs that are mirrored with respect to the central frequency of active bandwidth part (BWP), and the use of a random parameter to step through the frequency pattern. The sub-band location of the physical downlink shared channel that is scheduled by the physical downlink control channel may be indicated using the DCI format, or may be based on a last slot for PDCCH transmission.

Abstract: Devices, systems and methods for implementing beam failure management techniques at a user equipment (UE). The UE receives a timing advance command (TAC) from a currently camped cell and initiates a time advance timer (TAT). When the TAT is running the UE is in a first operating state. The first operating state indicates that the UE is in time alignment with the cell. The UE identifies that the TAT has expired. When the TAT is not running the UE is in a second operating state. The second operating state indicates that the UE is not in time alignment with the cell. The UE implements one or more beam failure management techniques based on the UE operating in the second operating state.

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.
