Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

Abstract: A user equipment (UE) may be in a standalone (SA) mode and start a timer associated with barring a first cell, based on a system information block type 1 (SIB 1) decode timeout failure. The UE may receive, from a base station, a first redirection instruction to connect to the first cell in a non-standalone (NSA) mode. The UE in the NSA mode may determine that the measurement for the first cell is greater than a threshold value, and receive, from the base station a second redirection instruction to switch to the SA mode on the first cell. The UE may pause the timer and perform an initial acquisition procedure on the first cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a configured set of control channel elements (CCEs) for physical downlink control channel (PDCCH) decoding for a scheduled cell of a set of scheduled cells, wherein the configured set of CCEs is on a per scheduled cell basis or a per carrier indicator field value basis. The UE may decode downlink control information (DCI) in one or more CCEs of the monitored configured set of CCEs. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.

Abstract: An example device includes memory configured to store the video data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine at least one of a temporal candidate or a history-based candidate and determine at least one non-adjacent candidate, wherein the at least one non-adjacent candidate is from a unit that is not adjacent to a current prediction unit (PU). The one or more processors are configured to determine an advanced motion vector predictor (AMVP) candidate list including the at least one of the temporal candidate or the history-based candidate and the at least one non-adjacent candidate. The at least one non-adjacent candidate is added to the AMVP candidate list after the temporal candidate or before the history-based candidate. The one or more processors are configured to code the current PU based on the AMVP candidate list.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface using a set of precoder configurations. In some aspects, the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with configuring the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflecting signals. The UE may additionally transmit, to the base station via the reconfigurable surface, a feedback message including an indication of at least one precoder configuration of the set of precoder configurations based on receiving the set of reference signals. The UE may then receive, from the base station via the reconfigurable surface, a downlink transmission based on transmitting the feedback message.

Abstract: A transmitter includes driver slices coupled to its output. Each driver slice includes a first differential predriver that is selectively enabled and disabled by a first switch based on a control code configuration. A second differential predriver provides a first differential buffered data signal to a first group of driver slices when the second differential predriver is enabled. A second switch enables the second differential predriver when the control code is configured to enable the first differential predriver in at least one driver slice in the first group of driver slices. A third differential predriver provides a second differential buffered data signal to a second group of driver slices when the third differential predriver is enabled. A third switch enables the third differential predriver when the control code is configured to enable the first differential predriver in at least one driver slice in the second group of driver slices.
