Abstract: A method, an apparatus, and a computer program product are provided. The apparatus may be configured to establish a first call for a first subscription, and accept a second call for a second subscription while maintaining the first call. A single RF transmit chain may be scheduled for uplink transmissions associated with the first call and uplink transmissions associated with the second call. A timesharing schedule for the transmit chain may determine timing for the uplink transmissions associated with the first call is transmitted and when the uplink transmissions associated with the second call is transmitted on the transmit chain. Downlink transmissions associated with the first and second calls may be received using different receive chain. Downlink transmissions associated with the first and second calls may be received using the same receive chain.

Abstract: A user equipment (UE) configured for dual connectivity with a split bearer configuration may transmit uplink data packets to one or both a master cell group (MCG) and a secondary cell group (SCG). The UE may transmit an uplink transmission from a packet data convergence protocol (PDCP) entity over one or both of a first radio link control (RLC) entity associated with the MCG and a second RLC entity associated with the SCG. The configuration including a transmit buffer threshold. The UE may receive, at the PDCP entity, an uplink switch start indication. The UE may activate the second RLC entity in response to receiving the uplink switch start indication. The UE may transmit a buffer status report according to a current transmit buffer level plus the transmit buffer threshold. Accordingly, the UE may communicate with the SCG based on the uplink switch start indication.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

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: 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.
