Abstract: Certain aspects of the present disclosure provide techniques for transmitting a random access channel (RACH) preamble. For example, certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes generating a message comprising a random access channel (RACH) preamble, determining an order of a plurality of beams for transmitting the message based on an indication of the order, and transmitting the message, to a network node, via the plurality of beams in accordance with the determined order of the beams.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a first sub-band and a second sub-band of a system bandwidth for communication with a user equipment (UE). The base station may determine a spatial quasi co-location (QCL) relationship between the first sub-band and the second sub-band and may transmit signaling to the UE that indicates the determined spatial QCL relationship. Upon receiving the signaling, the UE may derive, based on the indicated spatial QCL relationship, spatial parameters (e.g., beam width, pointing angle, etc.) for communication with the base station via the second sub-band. The spatial parameters may be derived based on spatial parameters used for reception of a downlink transmission from the base station via the first sub-band. Subsequently, the UE may communicate with the base station via the second sub-band using the derived spatial parameters.

Abstract: A user equipment (UE) may transmit a power headroom report in response to changing beamforming parameters. The UE may autonomously change beamforming parameters from a preconfigured set of beams or receive a command to change beamforming parameters for transmissions on a new beam. The UE may determine a power headroom applicable to a transmission from the UE on the new beam. The UE may transmit, in response to the command, a power headroom report based on the power headroom using resources configured for the power headroom report. For example, the power headroom report may be multiplexed with an uplink transmission from the UE using the new beam. In an aspect, the UE may select a scheduled transmission during a time period after the command is implemented as the uplink transmission. For example, the power headroom report may be transmitted as a physical layer transmission or as a MAC-CE transmission.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a plurality of beams from a base station (BS), measuring a value of a parameter associated with each of the plurality of beams, generating a report including at least the values of the parameter associated with the plurality of beams and/or an indication to implement soft-combining, transmitting the report to the BS, in response to transmitting the report: receiving a first beam including first redundant information and a second beam including second redundant information, and generating combined information based on the first redundant information and the second redundant information.

Abstract: Beam management enhancements for advanced millimeter wave (mm Wave) operations are disclosed. As a part of channel state information (CSI) reporting configuration, a user equipment may include an interference plus noise measurement of beams for consideration in beam management. The UE measures a set of signaling resources of each beam for power contribution and interference plus noise. According to the particular configuration, the UE may rank all of the available beams into a subset of the highest ranked beams, ranked either by the interference plus noise measurement, by the power contribution metric, or by a combination of both. The UE reports an identification of the subset to the serving base station which determines the beam to use for subsequent communications with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indicator of a feedback window that is offset relative to a beginning transmission time interval (TTI) of a set of consecutive TTIs. The consecutive TTIs may include a set of aggregated slots or may correspond to a multi-TTI grant. The feedback window may include multiple control channel occasions interspersed within a duration of the set of consecutive TTIs. The UE may receive a transport block within a first TTI of the set of consecutive TTIs and transmit, within a control channel, feedback to indicate whether the transport block was successfully received.

Abstract: Methods, systems, and devices for wireless communications are described that provide staggered synchronization signal blocks (SSBs) in frequency sub-bands for beamformed wireless communications. Transmissions of SSBs and control channel transmissions (e.g., remaining minimum system information (RMSI) physical downlink control channel (PDCCH) transmissions) may use multiple transmission beams in a beam sweeping procedure. The SSB transmissions may be transmitted using transmission beams that span one frequency sub-band of a number of available frequency sub-bands, and the control channel transmissions may use transmission beams that span two or more of the frequency sub-bands. The SSB beam sweeping procedure may be performed separately during staggered, non-overlapping time periods for each frequency sub-band of the number of frequency sub-bands. Each of the of SSBs may indicate a reference timing of the base station used to identify a set of resources (e.g., a control resource set (CORESET)) that carries control channel transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first carrier, an indication of an offset for scheduling a reference signal on a second carrier, wherein the offset indicates a duration between downlink control information (DCI), that schedules the reference signal, and the reference signal; determine a first numerology of the first carrier and a second numerology of the second carrier; and determine a time offset for the reference signal based at least in part on the offset and at least one of the first numerology, the second numerology, or both the first numerology and the second numerology. Numerous other aspects are provided.
