Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) is configured such that sounding reference signal (SRS) is switched among a number of antennas on a number of carriers associated with a default data subscription (DDS). The UE is also configured to receive a signal, scheduled using discontinuous reception (DRX), and associated with a non-default data subscription using at least one of the antennas used by the DDS. The UE determines based on carrier characteristics which resource is used to receive the signal during a DRX cycle. In some aspects, the decision is based on avoiding a conflict between the SRS switching and DRX reception. In further aspects, the decision is based on selecting the carrier contributing least to downlink throughput.

Abstract: A user equipment (UE) is configured to be connected to a 5G New Radio (NR) network that shares one or more frequency bands using dynamic spectrum sharing (DSS) with a Long Term Evolution (LTE) network that is transmitting LTE positioning reference signal (PRS). The UE may receive LTE PRS rate matching information from the NR network, such as the LTE PRS configuration data or an LTE PRS rate matching pattern. The UE may decode and process NR data signals and control signals transmitted by the NR network while LTE PRS is transmitted by rate matching around the LTE PRS in accordance with the LTE PRS rate matching information. The LTE PRS muting pattern may be adjusted based on NR data or control signals, and the UE may receive and process NR data and control signals transmitted while the LTE PRS is muted.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at user equipment (UE) of a mobile network, comprising monitoring an uplink metric of an uplink transmission channel. The aspects further include calculating an uplink transmit power based at least on a tolerance threshold. Additionally, the aspects include transmitting, via the uplink transmission channel according to the uplink transmit power, an uplink transmission. Additionally, the aspects include detecting a change in the uplink metric. Additionally, the aspects include comparing the change in the uplink metric with performance improvement criteria. Additionally, the aspects include determining whether to adjust the uplink transmit power. Additionally, the aspects include iterating adjustments to the uplink transmit power. Additionally, the aspects include stopping the adjustments to the uplink transmit power in response to determining that the uplink metric meets a performance threshold or in response to determining that the tolerance threshold has been met.

Abstract: Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

Abstract: A user equipment (UE) enhances positioning performance using Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) New Radio (NR)-Dual connectivity (EN-DC) based on an indication from the E-UTRAN base station that it is capable of EN-DC, e.g., in the upper layer indication of SIB2. When in idle mode, a UE that supports EN-DC and that has multiple carrier subscriptions may check the availability of EN-DC on both subscriptions that are camped on E-UTRAN base stations and use the subscription with EN-DC when a positioning session is initiated, e.g., from an emergency call. If one subscription is camped on a E-UTRAN base station and the other on an NR base station, the UE may use the E-UTRAN base station if EN-DC is supported or may use the NR base station if EONR and location based services are supported. A list of E-UTRAN base stations capable of EN-DC may be generated and used for selections of base stations to connect to or to prioritize during a handover procedure.

Abstract: Transmit output power for an uplink (UL) positioning sounding reference signal (SRS) may be determined by measuring output power of a transmit chain of a user equipment (UE) during an unused RACH occasion. A transmit output power offset is determined based on a difference between the measured output power and a predetermined output power. The transmit output power offset may be used to adjust the power output of the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is operating using a first subscriber identity module (SIM) in a non-standalone mode associated with a first radio access technology (RAT) and a second RAT, and that a second SIM has been activated for the UE. The UE may determine, based at least in part on user input, whether to operate in a multi-SIM mode, where both the first SIM and the second SIM are active, or to operate in a single SIM mode where only the first SIM, and not the second SIM, is active. The UE may selectively deactivate the second SIM based at least in part on determining whether to operate in the multi-SIM mode or the single SIM mode. Numerous other aspects are provided.
