Abstract: Wireless communication techniques for antenna-switched diversity and multi-SIM concurrent operation management are discussed. A UE may communicate via a transmission path associated with a first subscriber identification module (SIM). The transmission path may be mapped to one of a first one or more antennas in accordance with a determination as to whether the UE supports at least one of frequency-division duplex (FDD) antenna-switched diversity or time-division duplex (TDD) antenna-switched diversity when concurrently performing wireless communication associated with the first SIM and wireless communication associated with a second SIM. The UE may also communicate via at least one reception path associated with the second SIM. The at least one reception path may be mapped to a second one or more antennas in accordance with the determination as to whether the UE supports at least one of FDD antenna-switched diversity or TDD antenna-switched diversity.

Abstract: Apparatus, methods, and computer-readable media for facilitating managing multi-SIM concurrent mode for TDD co-banded or spectrum overlap carriers are disclosed herein. An example method for wireless communication at a user equipment (UE) includes estimating a maximum transmit power for a first subscriber based on a low-noise amplifier (LNA) input power threshold associated with an active receive chain of a second subscriber, where the UE comprises the first subscriber and the second subscriber. The example method also includes transmitting, via an active transmit chain of the first subscriber, an uplink transmission at the first subscriber maximum transmit power based on the first subscriber and the second subscriber operating concurrently, and a transmit power associated with the uplink transmission being greater than the first subscriber maximum transmit power.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless devices (e.g., dual subscriber identity modules (SIM) devices) may support two subscriptions such that while one subscription is actively transmitting or receiving, the other subscription is put on standby. The wireless device may identify collisions in time between monitored paging messages associated with the first and second subscriptions. Accordingly, the wireless device may modify a radio access technology (RAT) priority setting for one of the subscriptions, such that paging messages may be received via a RAT different that the RAT used for the other subscription (e.g., following a cell reselection procedure performed according to the modified RAT priority). Operation using a modified RAT priority setting may be referred to as a fallback mode, which may be exited upon expiration of a timer. Additionally, discontinuous reception (DRX) durations associated with the RATs used for subscription paging may be reduced.

Abstract: A method for call setup for a voice-over-long-term evolution (VoLTE) call on multi-subscriber identity module (SIM) multi-standby (MSMS) mobile communication device includes: receiving a long-term evolution (LTE) page; determining whether a WiFi connection is available; in response to determining that the WiFi connection is not available, determining whether the LTE page was received on a non-dedicated data subscription (DDS) subscription; and in response to determining that the LTE page was received on the non-DDS subscription, granting a highest priority for communication activities to an LTE page response on the non-DDS subscription.

Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: A multi-subscriber identification module (MSIM) wireless communication device may have at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that the first SIM is set as a designated data subscription (DDS), such that a modem stack associated with the first SIM receives information broadcast by a first network. The wireless communication device may perform a network attach procedure with a second network on a modem stack associated with the second SIM, such that a default packet data network (PDN) connection is established with the second network. The wireless communication device may set the default PDN connection as a persistent PDN connection, with the modem stack associated with the second SIM maintaining at least one persistent PDN connection.

Abstract: Methods and devices for implementing dynamic receive mode management to improve data throughput and paging performance on a multi-subscriber identification module (SIM) wireless communication device may include detecting, on a protocol stack associated with a first SIM, an active communication in a first network, detecting, on a protocol stack associated with a second SIM, an idle mode paging cycle in a second network, prompting entry into a selected dual receive mode on the shared RF resource, and monitoring at least one performance metric for the idle mode paging cycle associated with the second SIM while in the dual receive mode. Based on the monitored performance metric while in the dual receive mode, the wireless communication device may determine whether paging performance is degraded for the second SIM, and if so, trigger entry into a fallback mode on the shared RF resource.
