Abstract: Improvements may be made for an apparatus performing 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, where each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The one or more channel resource utilization limits are also a function of a CBR limit. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, and each packet of the plurality of packets has a respective packet priority.

Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation. An exemplary method performed by a base station generally includes determining, based on a location of another base station and information regarding the other base station, that the other base station is likely to experience interference while receiving an uplink transmission due to a downlink transmission by the base station and forming a null in a beam of the downlink transmission in a direction matching the location of the other base station.

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 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.

Abstract: Apparatus and methods for long term evolution (LTE) licensed-assisted access (LAA) communications at a user equipment (UE) are described herein. In an aspect, an example method includes a user equipment (UE) receiving a radio resource control (RRC) message from an eNB and searching for a discovery reference signal (DRS) associated with a secondary cell (Scell) of the eNB based at least on the information received in the RRC message. The example method further includes transmitting on the channel detected during the search.
