Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.

Abstract: Methods, systems, and devices for wireless communications are described that provide for identification of beamforming parameters for a downlink transmission beam based at least in part on a set of rules that define a priority order for control transmission and data transmissions. Downlink resources may be allocated to a user equipment (UE) for a downlink transmission via a first set of downlink beamforming parameters, and the UE may also be configured to monitor a control resource set using a different set of downlink beamforming parameters within a same transmission time interval (TTI) as the downlink transmission. A UE and a base station may identify which beamforming parameters to use for the downlink transmission based on the priority order. The set of rules may define which set of downlink beamforming parameters are to be used, whether the downlink transmission is rate-matched around the control resource set, or combinations thereof.

Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink power control. Certain aspects provide a method for performing uplink power control at a base station (BS). The method includes determining a first configuration of one or more parameters for uplink power control at a user equipment (UE) based on a first spatial beam selected, from a plurality of spatial beams, for uplink communication of the UE. The method further includes transmitting a first indication of the first configuration to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a trigger event configuration for power headroom reporting for a first service type that has a lower latency condition and a higher reliability condition than a second service type. For example, the first service type may be for low latency communications, and the second service type may be for mobile broadband (MBB) communications. The UE may detect a trigger event for power headroom reporting for the first service type based on the trigger event configuration. The UE may transmit a power headroom report for the first service type based on detecting the trigger event. By transmitting the power headroom report for the first service type, the UE may indicate whether power boosting for the first service type is available.

Abstract: An example method of wireless communication includes applying, by a first wireless communication device, a scrambling sequence associated with a cell to a set of symbol groups in a repetition. The method also includes transmitting, by the first wireless communication device to a second wireless communication device associated with the cell, the set of symbol groups after the scrambling sequence is applied to the set of symbol groups. Another example method of wireless communication includes applying, by a first wireless communication device, a frequency shift associated with a cell to a set of symbol groups in a repetition. The method also includes transmitting, by the first wireless communication device to a second wireless communication device associated with the cell, the set of symbol groups after the frequency shift is applied to the set of symbol groups.
