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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate on a first set of carriers in a first frequency range (FR) and a second set of carriers in a second FR. The UE may detect a radio link control (RLC) discontinuity on at least one of the first set of carriers or the second set of carriers. The UE may identify one or more FRs, of the first FR and the second FR, in which the RLC discontinuity occurred. The UE may transmit an RLC status report based at least in part on the identified one or more FRs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first downlink control information (DCI) indicating a first redundancy version (RV) index value associated with a hybrid automatic repeat request (HARQ) process. The mobile station may transmit, based at least in part on receiving the DCI indicating the first RV index value, data using a second RV index value, the second RV index value being different from the first RV index value. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a device-configured split data threshold for utilizing split data radio bearers (DRBs). A method that may be performed at a user equipment (UE) includes setting a device-configured split data threshold to a value that is less than or equal to a network-configured split data threshold value in response to the network-configured split data threshold value being greater than a first buffer threshold value associated with a data buffer of the UE, monitoring an amount of data in the data buffer, and triggering a first scheduling request (SR) associated with a first communication link and a second SR associated with a second communication link in response to the amount of data in the data buffer being greater than the device-configured split data threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first wireless connection with a first wireless device, and a second wireless connection with the first wireless device or a second wireless device, where the first wireless connection and the second wireless connection operate in a dual connectivity mode. The UE may identify first and second energy efficiency metrics associated with the first and second wireless connections, respectively. The UE may identify one or more parameters associated with a transmit power of communications at the UE, and may compare the first energy efficiency metric and the second energy efficiency metric. The UE may then allocate a first power resource to the first wireless connection, a second power resource to the second wireless connection, or both, based on the comparison, the one or more parameters, or a combination thereof.

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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing scheduling requests (SRs) in a user equipment (UE) that supports a split data radio bearer (DRB). In some aspects, the UE may trigger a first SR for a first communication link and a second SR for a second communication link in response to determining that a first amount of data in the UE data buffer is greater than a first threshold. The UE may transmit the first SR to a first base station (BS) via the first communication link. Prior to transmission of the second SR, the UE may determine whether a second amount of data in the UE data buffer is less than a second threshold. The UE may cancel the second SR in response to the second amount of data in the UE data buffer being less than the second threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive protocol data units (PDUs) in multiple TTIs (e.g., slots). The wireless communication device may generate, for each TTI of the multiple TTIs, a descriptor that identifies serial numbers (SNs) of PDUs that are received in the TTI. The wireless communication device may aggregate the descriptors for the multiple TTIs into an aggregated descriptor that identifies the SNs of the PDUs across the multiple TTIs. The wireless communication device may process the PDUs received in the multiple TTIs based at least in part on the aggregated descriptor. Numerous other aspects are described.
