Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a misalignment between system frame numbers (SFNs) associated with multiple serving cells in an asynchronous carrier aggregation configuration. The UE may select an SFN to use as an input for calculating a transmission parameter associated with communicating with one or more of the serving cells. Additionally, the serving cells may identify which SFN the UE selects in order to communicate efficiently with the UE. In some examples, the UE may receive an explicit indication of which SFN to use, and select the SFN accordingly. In other examples, the UE may select which SFN to use based on one or more parameters associated with the serving cells in the asynchronous carrier aggregation configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a first beam failure recovery (BFR) has been triggered; determine BFR information associated with the BFR; determine whether at least part of the BFR information has not been transmitted since a second BFR was triggered; and transmit, based at least in part on the determination that the BFR has been triggered and the determination that at least part of the BFR information as not been transmitted since a second BFR was triggered, a BFR message including the BFR information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, one or more downlink reference signals. The UE may transmit, to the base station, a random access channel (RACH) message associated with a RACH procedure using a first RACH configuration that is associated with repetitions or a second RACH configuration that is not associated with repetitions based at least in part on whether a measurement of the one or more downlink reference signals satisfies a measurement threshold, wherein a selection of a RACH configuration is evaluated by the UE prior to a transmission of an initial message associated with the RACH procedure. 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 receive an indication of a configuration for a discontinuous reception (DRX) cycle periodicity, the indication including a selection of a non-integer number for the DRX cycle periodicity. The UE may receive one or more communications based at least in part on the configuration for the DRX cycle periodicity. 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 receive first information indicating a first set of parameters associated with repetition of a second random access message (RAM) associated with a random access channel (RACH) procedure. The UE may transmit, using the first set of parameters, an initial RAM in association with the RACH procedure. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to configurations for new radio (NR) devices with reduced capabilities. In some aspects, a user equipment (UE) may determine a configuration from stored configuration information, where the configuration specifies a subset of features that NR UE with reduced capabilities is to support. The UE may communicate according to the configuration of reduced capabilities, or fall back to a set of further reduced UE capabilities. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: The UE may perform a measurement of downlink reference signals from a serving cell and at least one neighbor cell and skip one or more RRM measurements based on a comparison of the measurement for at least one round of measurements and a threshold value. The measurement of the downlink reference signals may include a measurement of a Doppler shift, a measurement of a positioning reference signal, or a measurement of a reception timing drift based on the downlink reference signals.
