Abstract: Enhanced inter-RAT and measurement gap operations are disclosed. In one aspect, a device may generate a customized measurement gap for monitoring control signals of another network for inter-RAT procedures. In another aspect, a device may modify, such as extend or shift, a network measurement gap to generate a modified measurement gap for monitoring control signals of another network for inter-RAT procedures. The device may modify the network measurement gap to align the network's measurement gap, such as LTE measurement gap, with a measurement window of another network, such as an SMTC window of a 5G network. Other aspects and features are also claimed and described.

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. In some systems, a user equipment (UE), such as a dual-subscription UE, support a first subscription and a second subscription. The first subscription may be in an active mode with a first cell and the second subscription may be in an idle mode with a second cell, and the UE may determine whether to exit or postpone entrance into a merged state in which the UE may perform idle mode measurements for the second subscription using the first subscription and the first cell based on a channel quality-based merge condition. For example, the UE may measure a channel quality associated with a communication link between the UE and the first cell and, in examples in which the measured channel quality fails to satisfy a threshold channel quality, the UE may exit or postpone entrance into the merged state.

Abstract: Apparatuses and methods for a wireless communication device having a first Subscriber Identity Module (SIM) and a second SIM to manage communication via the first SIM and the second SIM are disclosed. The method can include, but is not limited to, sending a first message including an indication of an extended signaling capability, receiving a second message including an inquiry regarding the extended signaling capability, and sending a third message including extended capability information, responsive to receiving the second message.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may generate a scheduling request for transmission to a base station. The UE may pause a transmission of the scheduling request according to an overlap in time between a response window associated with the scheduling request and a scheduled tuneaway period of the UE. The UE may tune away from the base station during the tuneaway period. The UE may transmit the scheduling request after a completion of the tuneaway period according to the pausing.

Abstract: Certain aspects of the present disclosure are generally directed to extended signaling protocols for multi-subscriber identity module (MSIM) user-equipment (UE) for new radio (NR). For example, certain aspects provide a method for wireless communication by a UE. The method generally includes receiving a first message from a network entity enquiring regarding information associated with a multi-subscriber identify module (SIM) capability of the UE, determining the information associated with the multi-SIM capability of the UE in response to the inquiry from the network entity, and communicating one or more messages to indicate the information regarding the multi-SIM capability to the network entity.

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.

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: A user equipment (UE) expedites cell reselection. In one instance, the UE starts a reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.
