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.

Abstract: To facilitate coexistence of a first radio access technology (RAT) and a second RAT, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating based on a RAT includes receiving a sidelink resource reservation from a second wireless device based on a second RAT, the sidelink resource reservation indicating a first set of resources. The example method further includes determining whether to exclude, from a candidate resource set for the first RAT within a sidelink resource pool for the first RAT, resources that overlap with the set of reserved resources for the second RAT. The example method further includes transmitting a sidelink transmission using one or more sidelink transmission resources selected from the candidate resource set in the sidelink resource pool for the first RAT.

Abstract: Using a modulation and coding scheme for a control channel that is more conservative than needed to fulfill the control function may waste resources. To address this issue, a variable size control channel is provided. An apparatus in such a system may be configured to determine an aggregation level of a plurality of aggregation levels associated with a control channel. Each aggregation level of the plurality of aggregation levels is associated with a number of time-frequency resources dedicated for the control channel and a particular modulation and coding scheme used for modulating and coding control information in the control channel. The apparatus is configured to receive control information in the time-frequency resources associated with the aggregation level and decode the control information received in the time-frequency resources associated with the determined aggregation level. The decoding is based on the particular modulation and coding scheme associated with the determined aggregation level.

Abstract: Wireless communication devices are adapted to facilitate power conservation and sidelink communications. According to one example, a wireless communication device can transmit a reservation signal to reserve one or more sidelink resources for use by another device, and receive a sidelink transmission from the other device on at least a portion of the one or more reserved sidelink resources. According to another example, a wireless communication device can detect a reservation signal from another device, where the reservation signal is configured to reserve one or more sidelink resources, and transmit a sidelink transmission on at least a portion of the one or more of the sidelink resources reserved by the other device. Other aspects, embodiments, and features are also included.

Abstract: Aspects of the present disclosure are directed to device-to-device (D2D) and, more particularly, vehicle-to-vehicle (V2V) communication in which an efficient ranging protocol allows efficient ranging-assisted vehicle positioning. A vehicle transmits a first slot ID in a first control period, to indicate a first time slot for transmitting a first ranging signal in a ranging cycle including a plurality of time slots. The vehicle transmits the first ranging signal in the first time slot in the ranging cycle. From a second vehicle, the first vehicle receives a second ranging signal in a second time slot that is different from the first time slot in the ranging cycle. The first vehicle determines a first time-of-arrival (ToA) of the second ranging signal when received by the first vehicle, and transmits the first ToA in a second control period.

Abstract: A method, apparatus, and computer-readable medium are provided for wireless communication at a Road Side Synchronization Device (RSDS). The RSDS receives, from a first neighbor device, a first Sidelink Synchronization Signal (SLSS). The RSDS synchronizes in time/frequency with the first neighbor device, and transmits a second SLSS. The second SLSS is based on a synchronized timing and a synchronized frequency with the first neighbor device.

Abstract: In an aspect, a vehicle apparatus of a vehicle obtains, based on sensor data from one or more vehicle sensors communicatively coupled to the vehicle, intra-lane position data relative to the vehicle, the intra-lane position data indicating at least one lateral distance between at least one side of a primary vehicle and at least one lane reference point. The vehicle apparatus transmits the intra-lane position data to one or more neighboring entities. In another aspect, a vehicle management device obtains intra-lane position data that indicates at least one lateral distance between at least one side of at least one observed vehicle of a plurality of neighboring vehicles and at least one lane reference point, and instructs at least one vehicle of the plurality of neighboring vehicles to perform one or more actions based on the intra-lane position data.

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.
