Abstract: Methods, systems, and devices for wireless communication are described. Data may be received during transmission time intervals (TTIs) that have a short duration relative to other TTIs. The short-duration TTIs may occur within or overlap a longer duration TTI, such as a subframe. Feedback responsive to the data may be generated and assigned for transmission during an uplink TTI according to a feedback timing or delay, which may be selected to reduce latency or balance the payload size of uplink messages sent during the assigned uplink TTI. Data and feedback assignments in short-duration TTIs may be configured based on a time division duplexing (TDD) configuration for some TTIs (e.g., subframes). TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Portions of special TTIs may be used for transmissions according to shorter-duration TTIs.

Abstract: Certain aspects of the present disclosure provide techniques for beam switching gaps. A base station (BS) can send an allocation to a user equipment (UE) including an at least one symbol beam switching gap based, at least in part, on a subcarrier spacing (SCS) of the UE. The UE and BS can then communicate using the allocation. The allocation may also be based on reported capability of the UE. The allocation may also be based on capability of the BS. The beam switching gap can be allocated explicitly or implicitly.

Abstract: Methods, systems, and devices for wireless communications are described in which a transmitting device using shared radio frequency spectrum may perform a listen before talk (LBT) procedure for at least a minimum dwell time and, upon successful completion of the LBT procedure, may occupy the spectrum for up to a duration of a channel occupancy time (COT). The transmitting device may discontinue transmitting during the COT for a gap period, and resume transmitting subsequent to the gap period without performing another LBT procedure. The minimum dwell time may be based on a periodicity of a channel reservation signal transmitted by one or more other devices using the shared radio frequency spectrum. In some cases, the transmitting device may schedule one or more receiving devices with resources for transmissions during the COT, and the receiving devices may perform a LBT that is non-adjacent with an associated transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a beam switching capability for a subcarrier spacing for communications between the UE and a base station. In one example, the beam switching capability may indicate a quantity of beam switches for a plurality of slots of a transmission time interval. In another example, the capability may indicate a threshold quantity of symbol periods between beam switching operations associated with the subcarrier spacing, or a beam switching time for the subcarrier spacing, or both. The UE may determine, for the identified beam switching capability, one or more parameter values that indicate the identified beam switching capability. The parameters may explicitly or implicitly indicate the identified capability. The UE may also transmit the determined one or more parameter values to the base station and communicate with the base station according to the identified beam switching capability.

Abstract: Methods, systems, and devices for scrambling initialization indication for higher bands are described. For example, a user equipment (UE) may receive a synchronization signal block (SSB) from a base station, the SSB including a primary synchronization signal (PSS), a data payload, and a demodulation reference signal (DMRS). The UE may identify a first part of a cell identifier (ID) of the base station, a second part of the cell ID, or both, indicated in a sequence of the DMRS, indicated in the data payload, or a combination thereof. The UE may monitor for a message from the base station based on identifying the cell ID.

Abstract: Resource selection for communication of uplink control information may include determining cyclic shift ramping for resource block (RB) sets. A user equipment UE) may use one or more RB sets for transmitting uplink control information on a shared radio frequency spectrum such as an unlicensed band. In some examples, the UE may transmit uplink control information to a base station (BS) via consecutive RB sets. To this end, the BS may schedule consecutive RB sets for an uplink transmission by the wireless communication device and monitor each of these RB sets for uplink control information.

Abstract: Aspects of the present disclosure provide systems and methods for assigning one or more user equipments (UEs) at one or more corresponding starting positions of multiple slots to perform channel access procedures, such as listen before talk (LBT) procedures in New Radio unlicensed band (NR-U) sidelink communications. The network entity may indicate, to a UE, a starting position in a multi-opportunity grant (e.g., a DCI scheduling multiple slots). The network entity may multiplex different transmitter UEs with different starting positions. If the channel accessing procedure is successful, the transmitter UE with the earliest starting position than the rest may block the rest of the transmitter UEs. In some cases, starting position hopping may be used so that the multiple UEs may have different priority at different slots. In some cases, the DCI may include LBT parameters that are inherited from NR-U uplink transmission configurations.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a grant to a first user equipment (UE) that indicates a resource allocation for a sidelink communication, either from the first UE to a second UE or from the second UE to the first UE. The grant may include a destination identifier associated with the sidelink communication, as well as a mapping between the resource allocation and the destination identifier. The destination identifier may be based on information in an indication received from the first UE. In some examples, the base station may configure a default receiver UE for transmissions from the first UE, and the base station may identify a receiver UE in the grant if the intended receiver UE is different than the default receiver UE.
