Abstract: Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines a channel busy ratio (CBR). The UE determines one or more channel resource utilization limits based on the CBR, wherein each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, each packet of the plurality of packets being associated with a respective packet priority.

Abstract: Techniques for adjusting a contention window (CW) for transmissions in a shared radio frequency spectrum band may include identifying a number of nodes attempting to transmit using a channel of a shared radio frequency spectrum band and determining a target CW based on the number of nodes attempting to transmit. A new CW value may then be determined based on a prior CW value and the target CW value, and a listen-before-talk (LBT) procedure (e.g., a clear channel assessment (CCA)) to access the channel of the shared radio frequency spectrum band may be performed to access the channel.

Abstract: In order to provide a generic access rule, the present disclosure proposes a new potential set of adaptivity rules for LBE based on LBT. The generic access rule of the present disclosure provides LTE-U and Wi-Fi coexistence and DL/UL coexistence in both LTE-U and Wi-Fi. The apparatus receives, from the first master device, a resource allocation for communicating with the second master device. The apparatus also determines a type of CCA procedure to perform before communicating with the second master device on an unlicensed channel. The apparatus further performs a CCA procedure to obtain a transmission opportunity based on the determining, the CCA procedure being one of an ICCA procedure or an ECCA procedure. In addition, the apparatus transmit data to the second master device in accordance with the resource allocation on the unlicensed channel when the transmission opportunity is obtained.

Abstract: Methods, systems, and devices are described for efficient use of transmit opportunities (TXOPs) through adjustment of contention window backoff time values to compensate for one or more TXOPs that may exceed a TXOP limit. A contention window value may be increased, for example, to provide other devices in the network with a fair opportunity for network access based at least in part on one or more TXOPs that exceed the TXOP limit. Allowing one or more transmissions to exceed a TXOP limit may provide enhanced efficiency as compared to having multiple transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a duty cycle function corresponding to a duty cycle range. In some cases, the UE may determine the duty cycle function based on a congestion metric. The UE may identify a bandwidth allocation for the UE and may determine a duty cycle within the duty cycle range based on the duty cycle function and the bandwidth allocation. In some cases, the UE may identify one or more of the duty cycle function, the congestion metric, the duty cycle range, or the bandwidth allocation based on control signaling from a base station. The UE may transmit a packet within the bandwidth allocation in accordance with the duty cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a wireless device with dual subscriptions to prioritize a subscriber. A user equipment (UE) may configure a first channel for a first subscription and a second channel for a second subscription. The UE may determine one or more slots for the first subscription for communicating in a first direction and for the second subscription for communicating in a second direction, where the first and second directions are different. The UE may prioritize communications of the first subscription according to the determined slots. The prioritizing may be based on the direction, whether the communications are scheduled or configured, or whether the slot includes a monitoring occasion. The UE may communicate in the first direction according to the first subscription.

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.
