Abstract: Methods, systems, and devices for wireless communications are described. Some user equipment (UE) may be equipped with multiple subscriber identity modules (SIMs). A multi-SIM UE may receive a control message at a first SIM which indicates a set of sounding reference signal (SRS) resources for receiving SRS according to a first periodicity. The UE may also receive a registration message at a second SIM which includes a first parameter indicating a first set of paging occasions for receiving paging messages in accordance with a second periodicity. The UE may identify a collision in time between the one or more SRS resources and paging resources, and may transmit a registration request message to a base station. The UE may then receive a second registration message which includes a second parameter for calculating a second set of paging occasions that have a third periodicity that are non-overlapping with the SRS resources.

Abstract: Methods, systems, and devices for wireless communications are described to support monitoring for paging messages from a base station (e.g., a cellular network node) using a greater periodicity than a discontinuous reception (DRX) cycle periodicity. A UE may monitor for and receive paging messages from a network node using a first subscription registered with a first radio access technology (RAT) while operating in DRX mode for a second RAT associated with the base station. The UE may identify a first periodicity for monitoring for paging messages from the base station that is greater than the DRX periodicity. The UE may have a second subscription that may be registered with a second base station. The UE may perform a tuneaway procedure from the second base station and monitor for paging messages from the base station according to the first periodicity.

Abstract: A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); transmitting a sounding reference signal (SRS) from a communication port of the UE, wherein the SRS has a timing offset assigned by a network associated with the first SIM; receiving paging messages from a network associated with a second SIM; determining an offset adjustment to avoid a collision between the SRS and the paging messages; sending a request to the network associated with the first SIM to adjust the timing offset according to the offset adjustment; and receiving an offset change configuration from the network associated with the first SIM.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reselection procedures for power saving in industrial internet of things (IIoT) operations. In a first aspect, a method of wireless communication includes a user equipment (UE) setting a reselection flag to a no-reselection state either by default or in response to a source cell signal-to-noise ratio (SNR) exceeding a predetermined maximum SNR. The UE can set the flag to the allow-reselection state in response to the target cell SNR range exceeding the source cell SNR range or the source cell SNR being below a predetermined minimum SNR. The UE may then either reselect to the target cell when appropriate or maintain service on the source cell based on the state of the reselection flag. Other aspects and features are also claimed and described.

Abstract: A multi-subscriber identification module (SIM) wireless communication device with a first SIM and a second SIM associated with a shared radio frequency (RF) resource may determine that timing collisions are predicted between an active period of a discontinuous reception (DRX) cycle associated with the first SIM and an active period of a DRX cycle associated with the second SIM. In response, the wireless communication device may determine whether the first SIM is registered with an IP Multimedia Subsystem (IMS) to use Voice-over-wireless local area network (VoWLAN) service over a wireless local area network (WLAN). If the first SIM is registered with the IMS to use VoWLAN service over the WLAN, the wireless communication device may shift the conflicting DRX cycle associated with the first SIM by a time margin, and receive paging messages for mobile terminating calls on the modem stack associated with the first SIM over the WLAN.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may switch the set of antennas that the UE uses to transmit sounding reference signal (SRS) transmissions. For example, the UE may switch from transmitting first SRSs that conflict with a scheduled communication from a first set of antennas to a second set of antennas (e.g., that is, the conflict may be at the first set of antennas). The UE may be transmitting second SRSs using the second set of antennas, and the switching may cause the UE to transmit the second SRSs using the first set of antennas instead. The second SRSs may not conflict with the scheduled communication (e.g., due to using different resources than the first SRSs), which may enable the UE to transmit the second SRSs and the scheduled communication using the same first set of antennas.
