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:
Systems and methods are disclosed for improving radio frequency coexistence in a multimodal device. The multimodal device may select a subset comprising at least one transmitter frequency channel (TFC) from among a set of TFCs associated with the multimodal device, transmit a transmission signal on each TFC of the selected subset, generate a power level measurement based on a signal received during transmitting of the transmission signal at a receiving frequency channel (RFC) associated with the multimodal device, and identify a self-interfering TFC from among the set of TFCs based on the selected subset and the generated power level measurement.
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 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.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a radio associated with the UE, an energy usage in a past transmit interval. The UE may determine, for the radio, a requested usage-aware energy reservation based at least in part on the energy usage in the past transmit interval. The UE may assign, for a next transmit interval, an energy budget limit for the radio based at least in part on the requested usage-aware energy reservation. The UE may transmit, via the radio, an uplink transmission based at least in part on the energy budget limit. Numerous other aspects are described.
Abstract:
Certain aspects of the present disclosure provide techniques for transmit energy allocation. A method that may be performed by a wireless device includes establishing first and second wireless communication connections and allocating an available energy between the first and second wireless communication connections by: allocating a first portion of the available energy to the first wireless communication connection based at least in part on one or more functionalities associated with the first wireless communication connection; allocating a second portion of the available energy to the second wireless communication connection based at least in part on one or more functionalities associated with the second wireless communication connection; and allocating a third portion of the available energy to the first and/or the second wireless communication connections based at least in part on energy efficiencies of the first and second wireless communication connections.
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 (HARD) 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:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain hybrid automatic repeat request (HARQ) information indicating whether the network node is configured to perform a retransmission of decoding information prior to an end of HARQ processes associated with the network node. The UE may receive, for a HARQ process associated with a downlink communication from the network node, a retransmission of a transport block (TB) that is associated with a reserved MCS when full decoding information for the TB is unavailable. The UE may perform, based on a reception of a retransmission, an action to proceed with the HARQ process, to restart the HARQ process, or to terminate the HARQ process, wherein the action is based on whether the network node is configured to perform the retransmission of the indication of the MCS. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify, for removal from a hybrid automatic repeat request (HARQ) buffer of the wireless communication device, a HARQ process from a plurality of HARQ processes maintained in the HARQ buffer by the wireless communication device, wherein the HARQ process is identified based at least in part on one or more HARQ buffer management parameters. The wireless communication device may remove the HARQ process from the HARQ buffer. Numerous other aspects are described.
