Abstract: Certain aspects of the present disclosure provide techniques for determining and utilizing resources for communicating an acknowledgment message (ACK). In certain aspects, a method generally includes determining a number of bits to utilize for communicating an acknowledgement (ACK) for a data transmission on a physical downlink shared channel (PDSCH). The method further includes determining a resource on a physical uplink control channel (PUCCH) to utilize for communicating the ACK based on the number of bits. The method further includes communicating the ACK on the resource.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for buffer management for a user equipment (UE) for multiple radio access technologies (RATs). Certain aspects provide transmitting data using a first RAT and second RAT to the UE based on an assumed size of a first portion of a buffer at the UE assumed allocated for storing data received by the UE using the first RAT and an assumed size of a second portion of the buffer assumed allocated for storing data received by the UE using the second RAT. The size of the first portion is based on a first number of resources the UE is capable of using for communicating and a second number of resources the UE is configured or allocated to use. The size of the second portion is based on an overall size of the buffer and the size of the first portion.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to transmitting uplink control information (UCI) in a short duration. In certain aspects a method includes identifying resources, within an uplink short burst (ULSB) region within a transmission time interval (TTI), for transmitting at least a portion of uplink control information (UCI), the UCI including at least one of one scheduling request (SR) bit and one or more acknowledgment (ACK) bits for acknowledging or negatively acknowledging downlink transmissions. In certain aspects, the method also includes transmitting the UCI using the identified resources.

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.
