Abstract: A downlink control information (DCI) is received. The DCI indicates one or more transmission configuration indication (TCI) states. A first pathloss between a transmission reception point (TRP) and a first panel of a wireless device is measured based on one or more pathloss reference signals (RSs). A second pathloss between the TRP and a second panel of the wireless device is measured based on the one or more pathloss RSs. A pathloss is determined based on a quantity of the one or more TCI states indicated by the DCI. The pathloss is a combined pathloss based on the first pathloss and the second pathloss in response to the quantity being equal to one. The pathloss is one of the first pathloss and the second pathloss in response to the quantity being greater than one. A transport block is transmitted with a transmission power based on the pathloss.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-beam related channel state information (CSI) reporting), a CSI processing unit (CPU) may process CSI calculations for a CSI report. A user equipment may have a set number of CPUs. In some cases, there may not be enough CPUs available to process a CSI report for each CSI-RS due the CPU capability of the UE. In such cases, the UE may select a subset of the CSI-RSs to generate an extrapolated CSI report. To extrapolate, the UE may measure channel conditions of at least some pre-configured number (e.g., at least two) of CSI-RSs and determine the channel condition of a point later in time and report this extrapolation in a CSI report to the base station. A base station may schedule future data transmissions with the user equipment based on the extrapolated CSI report.

Abstract: Various arrangements for using different air interfaces on adjacent frequency channels for side-link communications are presented. A first side-link channel may be split into a first bandwidth portion and the second bandwidth portion, in which the first bandwidth portion of the first side-link channel is directly adjacent to the second side-link channel. A first subcarrier spacing may be assigned to the first bandwidth portion of the first side-link channel. The second side-link channel may also use the first subcarrier spacing. A second subcarrier spacing may be assigned to the second bandwidth portion of the first side-link channel that differs from the first subcarrier spacing.

Abstract: A wireless device monitors a physical downlink control channel (PDCCH) of an active bandwidth part (BWP) during a discontinuous reception (DRX) active time. A switch is made to a first downlink BWP as the active BWP during the DRX active time. In response to the switching, a first PDCCH of the first downlink BWP is monitored and a BWP inactivity timer is started. A packet is transmitted via a transmission interval of periodic resources indicated by a configured grant. The BWP inactivity timer is restarted at a time based on the transmission interval. In response to an expiration of the BWP inactivity timer, a switch is made to a second downlink BWP as the active BWP during the DRX active time, and a second PDCCH is monitored.

Abstract: A first indication that indicates a time frequency region can be received. A second indication indicating the priority of an uplink transmission in a set of time frequency resources as a high priority uplink transmission can be received. Whether at least a portion of the set of time frequency resources of the high priority uplink transmission overlaps with the indicated time frequency region can be determined. Whether to transmit the high priority uplink transmission if at least the portion of the set of time frequency resources of the high priority uplink transmission overlaps with the indicated time frequency region can be determined. The high priority uplink transmission can be transmitted based on determining whether to transmit the high priority uplink transmission.

Abstract: A central analytics server can be utilized to analyze health data associated with one or more radio access networks (RANs) that has been aggregated from one or more mobile edge computing (MEC) servers, to determine throughput available at a radio link interface associated with a user equipment (UE). Further, the central analytics server can determine, based on the available throughput, a recommendation for an action that can be performed by a content server to optimize content delivery to the UE. In an example, the central analytics server can convey the recommendation to the content server(s) via a “window size” field within a header segment of a transmission control protocol (TCP) via in-band and/or out-of-band signaling. In one aspect, the recommendation can comprise instructions to adapt a bit stream and/or comprise instructions indicative of an optimal data transmission route.

Abstract: Time-division duplexing (TDD) in distributed communications systems, including distributed antenna systems (DASs) is disclosed. In one embodiment, a control circuit is provided and configured to control the TDD transmit mode of a DAS to control the allocation of time slots for uplink and downlink communications signal distribution in respective uplink path(s) and downlink path(s). The control circuit includes separate power detectors configured to detect either a transmit power level in a downlink path or a receive power level in an uplink path. If the transmit power detected in the downlink path is greater than receive power detected in the uplink path, the control circuit switches the TDD transmit mode to the downlink direction. In this manner, the control circuit does not have to control the TDD transmit mode based solely on detected power in the downlink path, where a directional coupler may leak uplink power in the downlink path.
