Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Abstract: A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Wireless communications systems may support identification or determination of a common default beam for a component carrier (CC) group (e.g., such that all CCs of a CC group may be associated with a same default beam). For example, a CC group may be configured or established to include one or more CCs (e.g., for carrier aggregation), where each CC group may share a same analog beamformer. As such, a beam (e.g., a default uplink/downlink beam) may be established as default or common across CCs of a CC group (e.g., versus default beams being configured or established for individual CCs). Such an established default beam of a CC group (e.g., a default beam common to all CCs of a CC group) may include or refer to a default downlink shared channel beam, a default sounding reference signal (SRS) beam, a default downlink control channel beam, etc.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving an indication that the UE has been added to a group. The method also includes receiving group common signaling informing the UE of a configuration change. A method of wireless communication by a base station includes defining a group of user equipments (UEs). The method also includes notifying each UE of the group of inclusion into the group of UEs. The method still further includes transmitting, to the group of UEs, group common signaling including a configuration change for the group of UEs.
