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: Improvement in co-existence of the LTE device-to-device communication with another device-to-device communication method is desired. The apparatus selects a countdown number within a size of a contention window including a plurality of slots before a target subframe. The apparatus determines whether each slot of the plurality of slots is idle or utilized while waiting for the target subframe. The apparatus counts down the countdown number during each of the determined idle slots. The apparatus determines whether the countdown number has reached a threshold number before the target subframe. The apparatus performs, when the countdown number is determined to have reached the threshold number, one of: deferring from transmitting until the target subframe, or transmitting a CUBS until a next subframe or the target subframe.

Abstract: One problem with current D2D communications is that there is no physical layer feedback (e.g., HARQ feedback) for unicast sidelink communications. That is, the transmitting UE does not know if the receiving UE receives and/or properly decodes the unicast transmission. Instead, current D2D communications require that a transmitting UE send a unicast sidelink communication multiple times to increase the chances that the unicast sidelink communication is received by the receiving UE. By blindly transmitting unicast sidelink communications multiple times, the spectral efficiency and radio resource utilization of the network is decreased. The present disclosure provides a solution to this problem by enabling HARQ feedback for unicast sidelink communications that improves the spectral efficiency and also enables better radio resource utilization for the network.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first link quality. The first link quality indicates a link quality of a first link between a first potential relay UE and the remote UE. The apparatus determines a second link quality. The second link quality indicates a link quality of a second link between the first potential relay UE and a first base station. The apparatus ranks the first potential relay UE relative to a second potential relay UE. The ranking of the first potential relay UE is based on a combination of the first link quality and the second link quality. The apparatus selects one of the first potential relay UE and the second potential relay UE for a relay connection based on the ranking of the first potential relay UE relative to the second potential relay UE.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.
