    Abstract: Methods, systems, and devices for wireless communications are described techniques provide for the identification of a sequence of beamforming parameters that are used for communications between a user equipment (UE) and a base station using a sequence of transmission beams. A UE may measure received reference signals that are transmitted in a series of downlink transmission beams from a base station, and report measurement parameters associated with the downlink transmission beams to the base station as part of a beam tracking and beam refinement procedure. The base station may provide transmission configuration indicator (TCI) states that are associated with each transmission beam. The TCI states may be recorded over a course of a periodic movement of the UE, and may be used deterministically to identify beamforming parameters for transmission and reception of a subsequent series of downlink transmission beams when the UE makes a subsequent same periodic movement.

    Abstract: Techniques for wireless communications over a shared radio frequency spectrum band, may include techniques for transmitting uplink data transmissions using allocated uplink resources. Allocated uplink resources may include an uplink channel (230, 240, 250) comprising a number of allocated interlaces of resource blocks, RBs (330, 730, 930, 1130) for use by a user equipment, UE (115, 215, 215-a, 215-b, 215-c, 140 I). An incoming data stream may be processed and data separated into each of the allocated interlaces of RBs for the UE. Such separation may be through demultiplexing the data stream to obtain data for the allocated interlaces of RBs. The demultiplexed data may be mapped onto associated resource elements (335, 735, 935, 1135) associated with the allocated interlaces of RBs, and transmitted. Different types of uplink channels, such as a physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) and/or a physical random access channel (PRACH) may be allocated to interlaces of RBs in one or more subframes of a transmitted radio frame.

    Abstract: Uplink control channel transmission in a shared radio frequency spectrum band may be transmitted using different uplink resources UCI based on a format of uplink control information (UCI) to be transmitted in the uplink control channel transmission. Different time resources, frequency resources, or combinations thereof, for the transmission of UCI by a UE may be provided by a base station and selected by the UE based on a UCI format. The resources to be used for UCI transmission may semi-statically configured, or dynamically indicated to a UE. Uplink transmissions may be configured in interlaces of frequency resources, with each interlace having one or more segments, and a base station may configure different segments for transmission of different format UCI. In some cases, different subframes, or different component carriers, may be configured for different formats of UCI.

    Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.
