Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine an emissions mask (e.g., an in-band emission (IBE) mask) for a user equipment (UE) which may be determined based on the total number of UEs scheduled by the base station for uplink transmissions during a same transmission time interval (TTI). The base station may transmit downlink control information (DCI) to the UE indicating the emissions mask. The base station may additionally transmit a grant to the UE allocating resources for the UE based on the UE's position relative to other UEs served by the base station. The UE may receive the DCI and may map the emissions mask to a maximum power reduction (MPR). Based on the MPR, the UE may determine a transmit power and may transmit an uplink transmission to the base station according to the transmission power and the DCI.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a channel raster associated with a plurality of resource blocks of a channel. The plurality of resource blocks may have an asymmetric relation with respect to the channel raster. The base station may configure, based at least in part on the asymmetric relation, a message to indicate a resource block offset metric that comprises an indication of the channel raster and location information associated with a first resource block of the plurality of resource blocks. The base station may transmit the message to convey the indication of the resource block offset metric.

Abstract: Improvements may be made for the Channel Busy Ratio, CBR, based congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a User Equipment, UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.The adjusting may be carried out taking into account a usage limit, or CBR limit. In addition, the UE may detect that a second technology different from a first technology is also using the channel, and in addition consider a decode-based CBR for the purpose.

Abstract: A framework to manage coexistence of multiple technologies over multiple channels is desired. The apparatus may be a user equipment (UE). The UE detects whether a second technology different from a first communication technology utilized by the UE is active on a first channel. The UE performs, based on the detection, an action associated with assigning the first communication technology to at least one of the first channel or a second channel.

Abstract: A user equipment may be configured to limiting transmit power for frequency domain division for high power user equipment. In some aspects, the user equipment may determine a UE context is interference limited or noise limited based on comparing a measurement value to a threshold value, set a maximum transmit power based on the UE context, and transmit, during a time period associated with a downlink (DL) grant, an uplink (UL) transmission at the maximum transmit power.

Abstract: Wireless communications systems and methods related to narrow beam-based channel access for communications in a wireless communication network operating over an unlicensed spectrum are provided. A first wireless communication device receives, from a second wireless communication device, one or more signals associated with a beam parameter. The first wireless communication device determines, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals. The first wireless communication device determines, based at least in part on an p-th percentile signal measurement and a q-th percentile signal measurement of the signal measurements at the plurality of locations, whether the second wireless communication device satisfies an interference condition.

Abstract: Adaptive energy detection (ED) threshold medium access is discussed based on deployment and traffic type. The network nodes sharing a shared communication network are configured with multiple discrete ED thresholds or a range of ED values. As a transmitting node prepares to attempt access to the shared communication spectrum, it identifies an access trigger condition within the network. Such a condition may include traffic type, deployment, or access conditions. In response to detecting an access trigger condition, the transmitting node may select an ED threshold associated with the access trigger condition. Alternatively, upon detection of the access trigger condition, the transmitting node may implement a random ED threshold from the candidate range of ED threshold values.

Abstract: Methods, systems, and devices for wireless communications are described. that support asymmetric time division duplexing (TDD) coexistence among different operators having adjacent nodes in wireless networks. A baseline TDD configuration may be established for a set of frequency bands, that provides that uplink (UL) transmissions and downlink (DL) transmissions within a set of frequency bands are aligned and result in relatively little or no interference among different operators. An operator may determine that a TDD configuration that is different from the baseline TDD configuration may be beneficial and may select an interference mitigation procedure and communicate with one or more UEs using the interference mitigation procedure and TDD configuration that is different than the baseline TDD configuration.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.
