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: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust transmit (Tx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when one subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Tx processing to mitigate the effects of de-sense on the victim.

Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX). According to one example, an access terminal determines to disable DTX, such that a continuous reverse link transmission may occur, in a fashion such as not to interfere with the operation of a Frame Early Termination operation utilized in CDMA 1x technology. As one example, the access terminal may cease the utilization of DTX in accordance with a performance metric of a wireless communication network. The performance metric may be a forward link power control setpoint of a base station, a number of quasi-orthogonal function sets being utilized at the base station, a number of frame erasures corresponding to a forward link transmission from the base station, or any other suitable measurable parameter of the network performance. Other aspects, embodiments, and features are also claimed and described.

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.
