Abstract: In an aspect, a scheduled entity obtains a first set of indications associated with a beam failure recovery procedure, starts at least one of a first timer or a second timer based on the obtained first set of indications, and detects a radio link failure when the first timer expires or when the second timer expires. In some aspects, the scheduled entity starts at least one of the first timer or the second timer when N out-of-sync indications are obtained over a network configured time window, the N out-of-sync indications including aperiodic out-of-sync indications from the first set of indications and out-of-sync indications associated with a radio link monitoring procedure. In some aspects, the scheduled entity starts at least the second timer when the first set of indications includes a single aperiodic out-of-sync indication.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a mismatch between a user's common search space (CSS) and user-specific search space (USS). A base station (BS) may receive an indication that a user equipment (UE) decoded at least one beamformed signal transmitted by the BS in a USS and did not decode at least one beamformed signal transmitted by the BS in a CSS. The BS may take one or more actions based, at least in part, on the indication. Similarly, a UE may decode at least one beamformed signal transmitted by a BS in a USS, transmit to the BS an indication that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a CSS, and take one or more actions based, at least in part, on the indication.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a signal characteristic of a unicast signal is better than a signal characteristic of a broadcast signal; and/or transmit, based at least in part on the determination, a request for an update to a master information block or a minimum system information block to be provided to the user equipment using the unicast signal. In some aspects, a base station may determine that a signal characteristic of a unicast signal associated with a user equipment (UE) is better than a signal characteristic of a broadcast signal broadcasted by the base station; and/or transmit, based on the determination, an update to a master information block (MIB) or a minimum system information block (MSIB) to the UE using the unicast signal. Numerous other aspects are provided.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Wireless communications systems and methods related to dynamic time-division duplexing (TDD) and self-contained subframe-based communications in a shared spectrum are provided. A first wireless communication device communicates a control information communication protection request over a shared spectrum. The shared spectrum is shared by a plurality of network operating entities based on priorities. The first wireless communication device is associated with a first network operating entity of the plurality of network operating entities. The first wireless communication device communicates, with a second wireless communication device associated with the first network operating entity, control information in a first link direction during a transmission opportunity (TXOP) in the shared spectrum. The first wireless communication device communicates, with the second wireless communication device, data in a second link direction during the TXOP.

Abstract: The present disclosure provides for fast radio resource management procedures for new radio. Generally, a fixed frame structure is utilized and all base stations are synchronized. A base station may transmit a reservation request during a first control slot for the base station in a reservation channel at a beginning of a synchronized frame. A first user equipment may transmit and the base station may receive a reservation response during a second control slot. The base station may receive, from the first UE, after a third control slot of the reservation channel for a neighboring base station, a reservation indication based on a measurement by the first UE of the neighboring base station or at least one other UE associated with the neighboring base station. The base station may determine, based on the resource indication, whether to schedule the first UE during a data channel of the synchronized frame.

Abstract: Certain aspects of the present disclosure relate to techniques for reducing the decoding complexity for low cost devices (e.g., low cost UEs). One technique may include simplifying the PDCCH format. This may include generating a compact DCI format for transmitting DCI to a low cost device. The compact DCI format may correspond to at least one standard DCI format used by a regular UE and may comprise a reduced number of bits when compared to the standard DCI format. Another technique may include reducing the number of blind decodes. This technique may include selecting a set of resources for transmitting DCI from a limited set of decoding candidates, such that a receiving low cost device need only perform blind decodes for the limited set of decoding candidates.
