Abstract: A grant may allocate resources for an uplink transmission by a user equipment (UE) in a system using beamforming, where the resources may be used by the UE to transmit data or control information during a time that a base station is listening in a certain receive beam direction. A UE may be in communication with a base station using beamformed transmissions, and the base station may send a resource grant to the UE for uplink transmissions that correspond to a receive beam direction of a beamsweeping operation. The UE may then transmit data and/or uplink control information to the base station according to the resource grant and when the base station is listening in the corresponding direction. In some examples, the UE may send the uplink transmission to the serving base station, and transmit a random access channel to another base station based on the beamsweeping operation.

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: A user equipment (UE) may be configured to communicate a number of transmissions that may each have separate feedback processes. A feedback configuration for providing feedback for such separate feedback processes may be determined based on semi-static signaling and dynamic signaling. In some cases, semi-static signaling, such as radio resource control (RRC) signaling and dynamic signaling, such as downlink control information (DCI), may together provide a feedback configuration for a particular transmission. The semi-static signaling may provide a number of bits of feedback information, an interpretation of the bits of feedback information, or combinations thereof, and dynamic signaling may indicate that one or more of the bits are to have one of a number of available interpretations, may indicate that one or more additional bits are to be included with feedback, of combinations thereof. Feedback techniques as discussed herein may be used to provide feedback for uplink or downlink transmissions.

Abstract: Aspects of the present disclosure implement techniques to allow a base station to transmit a “short-page” message (e.g., paging indicators) to one or more UEs. The short-page message may be decoded by all UEs in the paging cycle and identifies a subset of UEs from the full set of UEs that are paged by the base station. Upon decoding the short page transmitted by the base station, the UE may respond with a “short-page response” to the base station on a transmit beam that offers best signal quality (e.g., low signal-to-noise ratio, transmit power, etc.). Thus, in some examples, the UE, in response to receiving a short paging message, may provide feedback to the base station such that the base station may select a transmit beam for transmission for a subsequent message (and other communications).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive a downlink transmission from at least one beam of a set of beams. The set of beams may be associated with a multi-beam communication between the apparatus and a base station. The apparatus may select a beam, of the set of beams, to report beam related information associated with the at least one beam of the set of beams. The apparatus may report an indication that the beam is a selected beam.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.
