Abstract: A user equipment (UE) may camp on a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including access restrictions, wherein the access restrictions include one or more predetermined criteria that must be satisfied to camp on the base station. The UE then determines whether the UE satisfies the one or more predetermined criteria.

Abstract: Apparatus and methods for estimating data traffic characteristics for applications to condition data communication channels that support data packet transfer for the applications in wireless communication devices are disclosed. Data connections to support different applications and/or daemon software processes can be established and subsequently adjusted based on data traffic characteristics for data that the different applications/daemons generate and/or consume. Traffic flows for the applications/daemons are classified into traffic classes based on likely data traffic patterns. When data sources are added or deleted, changes to a traffic class state can be determined, and wireless circuitry adjusted based at least in part on the traffic class state and a traffic class policy. Adjusting parameters that affect the periodicity and/or length of active time periods and sleep periods in accordance with estimated data traffic patterns for applications/daemons that use the data connections can reduce power consumption by the wireless circuitry.

Abstract: A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.

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 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: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

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: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: A base station may restrict access by a user equipment (UE). The base station broadcasts access restrictions to one or more UE within a cell coverage area of the base station, wherein the access restrictions include one or more predetermined criteria that must be satisfied for a UE to be allowed to camp on the base station. The base station performs a random access channel (RACH) procedure to allow the UE to camp on the base station when the UE satisfies the one or more predetermined criteria.
