Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that uplink data is available for transmission at the UE prior to a scheduling request occasion. The UE may skip transmission of a scheduling request during the scheduling request occasion based on identifying that an uplink grant is pending. The UE may transmit at least a portion of the uplink data to a base station using a resource allocation indicated by the uplink grant. Alternatively, the UE may transmit the scheduling request to the base station during a first scheduling request occasion. The UE may initiate a retransmission timer based on transmitting the scheduling request. Accordingly, the UE may skip retransmission of the scheduling request during a second scheduling request occasion that is subsequent to the first scheduling request occasion based on the retransmission timer.

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: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract: Methods and apparatuses are presented for managing a multi-subscriber identity module (SIM) user equipment (UE) such that data throughput may be improved in a dual-SIM, dual active (DSDA) scenario. For example, a method is presented that includes acquiring first timing information of a first subscription and second timing information of a second subscription. Additionally, the example method may include detecting a first conflict between communications of the first subscription and the second subscription in a time slot of a first time interval. Moreover, the example method may include estimating one or more additional conflicts in one or more subsequent time intervals based on timing of the time slot, the first timing information, and the second timing information. Further, the example method may include respectively adjusting one or more transmit block sizes (TBS) for each of the one or more subsequent time intervals.
