Abstract: The present disclosure relates to transmitting and receiving improved quality reports using different transmission states. A base station may transmit to a user equipment (UE) a channel comprising multiple beams, wherein the beams include different Transmission Configuration Indicator (TCI) states. The UE can then perform beam quality measurements for the multiple beams. The beam quality measurements can include different channel quality indicator (CQI) measurements and can be performed using the same or different spatial filters. The UE can then determine a combined beam quality report for the different beams and transmit the report to the base station. The beam quality report can also comprise a comparison of, the difference between, or the average of, the different CQI measurements. The UE can also receive a configuration of filtering coefficients from the base station, wherein the beam quality report comprises filtered CQI information.

Abstract: Aspects described herein relate to configuring, at a device, default beam information for determining a beam for data channel communications. The device can determine to use the default beam information for configuring the beam for a data channel communication based on determining explicit beam information is not configured. In addition, the device can transmit, based on determining to use the default beam information, the data channel communication based on the beam configured using the default beam information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: A user equipment apparatus determines whether a transmission is received from a base station within a time window and skips measurement of a reference signal during a subsequent period, when a transmission is received from the base station within the time window. A base station apparatus configures a UE to monitor one or more reference signals associated with a beam pair link and transmits a first signal in a transmission to the UE. The base station determines whether the transmission is received at the UE within a time window and determines whether to transmit a reference signal, based on whether the transmission is received at the UE within the time window. Upon determining that the transmission was received at the UE, the base station may skip transmission of the reference signal or modify a time, a frequency, a power, and/or a reference signal offset for the reference signal.

Abstract: Certain aspects of the present disclosure relate to quasi co-location assumptions for aperiodic channel state information (CSI) reference signals (RS) in communications systems operating according to NR techniques. An exemplary method that may be performed by a UE includes determining a quasi-co-location (QCL) relationship of an aperiodic channel state information (CSI) reference signal (CSI-RS) to a physical channel and processing the aperiodic CSI-RS according to the determined QCL relationship.

Abstract: Aspects of the present disclosure provide for the transmission of group common control information in 5G New Radio (NR) wireless communication systems. Group common control information may be transmitted to a group or subset of user equipment (UEs) within a cell utilizing a beam-sweeping configuration. A base station may utilize a plurality of transmit beams to transmit information within the cell, and a subset of the transmit beams may be identified for use in transmitting the group common control information to the group of UEs. In addition, the base station may identify spatial quasi-colocation (QCL) relationships between reference beams corresponding in direction to the selected subset of transmit beams and resources reserved for the group common control information and provide the spatial QCL relationships to the UEs in the group.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for uplink power control using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communication by a base station includes providing power control parameters, to at least one user equipment (UE), for use in performing uplink transmit power control for one or more uplink transmissions sent using one or more uplink transmit beams, signaling the UE to set or reset one or more of the power control parameters, and transmitting one or more reference signals (RSs) using one or more downlink transmit beams, for the UE to measure for use in the uplink transmit power control.

Abstract: Aspects herein describe transmitting reference signals in wireless communications. An indication of resources over which to transmit an uplink reference signal can be received from an access point, where the resources are at least partially used by another device to transmit a downlink reference signal or a second uplink reference signal. The uplink reference signal can be transmitted over the resources.
