Abstract: A first network node (e.g., a UE) may receive, from a second BS network node (e.g., a base station), DCI. The first network node may perform, based on the DCI, a BWP switch from a first BWP to a second BWP. The first network node may perform, after the BWP switch, a BWP switch failure detection procedure that results in a first determination or a second determination. The first determination may be indicative that the BWP switch was successful and the second determination may be indicative that the BWP switch was not successful. To perform the BWP switch failure detection procedure, the first network node may determine whether one or more failure conditions are satisfied. The one or more failure conditions may include at least one of a BLER greater than a threshold, occurrence of one or more tune away events, or non-receipt of an uplink grant on the second BWP.

Abstract: Aspects of the disclosure relate to communication via a dual subscriber identification module (SIM) dual standby (DSDS) user equipment (UE) are disclosed. In an aspect, the DSDS UE may establish a first connection with a base station through a communication link via a first subscription using a frequency resource, and may establishing a second connection with the base station through the communication link via a second subscription using the frequency resource. The DSDS UE may further perform communication with the base station via at least one of the first subscription or the second subscription through the communication link using the frequency resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a first connected mode discontinuous reception (CDRX) configuration from a first cell associated with a first radio access technology (RAT), the first CDRX configuration includes a first indication of a first on occasion. The UE may receive a second CDRX configuration from a second cell associated with a second RAT, the second CDRX configuration includes a second indication of a second on occasion. The UE may determine that the first on occasion and the second on occasion are separated by a threshold. The UE may transmit, based at least in part on the determination that the first on occasion and the second on occasion are separated by the threshold, a CDRX reconfiguration request message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) determine that at least one packet of a set of packets for a downlink message is unsuccessfully received at a radio link control (RLC) layer of the UE due to a specific situation of a set of specific situations and may transmit the NACK message based on the missing packet (s) on an as needed basis rather than waiting for a timer to expire (e.g., a fast NACK mechanism). In some examples, the specific situations may include the UE missing packets after a measurement gap, missing packets based on wake up latencies for a discontinuous reception mode of the UE, missing packets due to interference from reference signals transmitted by neighboring cells, missing packets due to the UE not decoding retransmissions that have a same redundancy version (RV) of a downlink message, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with two subscriptions. The first subscription may support dual connectivity with one or more cell groups, such as a master cell group (MCG) and a secondary cell group (SCG), while a second subscription may not support dual connectivity. Each subscription may support communications with one or more radio access technologies (RAT). The UE may use the protocol stack for a RAT in the first subscription to receive idle-mode signaling, such as one or more paging messages, from the second subscription using the same RAT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during an ongoing data session on a first subscriber identity module (SIM), an incoming voice call on a second SIM. The UE may determine, during the ongoing data session on the first SIM, a caller identifier associated with the incoming voice call on the second SIM. The UE may initiate, on the first SIM, a communication to the caller identifier associated with the incoming voice call in concurrency with the ongoing data session. Numerous other aspects are described.

Abstract: A method of wireless communication by a user equipment (UE) supporting multiple subscriptions, includes camping on a first cell of a first radio access technology (RAT) with a first data subscription, and camping on a second cell of a second RAT with a second data subscription. The method also includes triggering a transition to the first cell of the first RAT for the second data subscription. The method further includes performing, with the first data subscription, activities on behalf of the second data subscription.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for releasing an RRC connection by a user equipment (UE). A method that may be performed by the UE includes establishing an RRC connection, determining a time duration for a release timer, resetting the release timer, monitoring the RRC connection, and releasing the RRC connection.
