Abstract: The present disclosure relates to methods and devices for communication which may include a transmitting device and at least one receiving device. In one aspect, the transmitting device may determine a transmission configuration including one or more aggregated transmission intervals for communicating with the receiving device. The transmitting device may also indicate the transmission configuration to the receiving device. Additionally, the transmitting device can transmit at least one data packet to the receiving device based on the transmission configuration. Further, the transmission configuration can indicate a number of the one or more aggregated transmission intervals. In some aspects, the receiving device can determine a number of aggregated transmission intervals based on the indication. The receiving device can also decode the data packet based on the number of aggregated transmission intervals.

Abstract: Techniques are described for wireless communication at a wireless device. One method includes transmitting, during a TTI, a first message using a first MCS; and transmitting, during the TTI, a second message using a second MCS. The first message includes indications of a location, a heading, and a speed of the wireless device, and the second MCS is higher than the first MCS. Another method includes decoding a first message received during a TTI; performing a Doppler effect compensation for a second message based at least in part on the first message; and decoding the second message based at least in part on the Doppler effect compensation. The second message is also received during the TTI. The first message is decoded in accordance with a first MCS, and the second message is decoded in accordance with a second MCS, with the second MCS being higher than the first MCS.

Abstract: Certain aspects of the present disclosure provide techniques relating to wireless communications between vehicles. In certain aspects, a method performed by a first vehicle comprises receiving an indication from a second vehicle comprising surrounding information that is indicative of whether a first unknown vehicle is detected by the second vehicle, wherein the first vehicle and the second vehicle are able to communicate wirelessly, and wherein the first unknown vehicle is unable to communicate wirelessly with the first and the second vehicles. The method further comprises controlling movement of the first vehicle based on the indication.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: The present disclosure relates to methods and devices for group communication which may include a first UE and a set of UEs. In one aspect, the first UE may receive from each UE of the set of UEs a PDU including a header that includes a QoS level for the UE. The first UE can also determine a supported QoS level for the first UE. In another aspect, the first UE can set a transmission QoS level for the first UE to be a lowest QoS level of the determined supported QoS level and the QoS level from each UE of the set of UEs. In a further aspect, the first UE can transmit by multicast to the set of UEs a PDU based on the set transmission QoS level.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (e.g., a base station and/or a user equipment) may receive, over a control channel, a first control signal identifying first scheduling information for a data transmission to the receiving device. The receiving device may determine a number of resource elements of a shared channel for a second control signal based at least in part on a first modulation and coding scheme (MCS) table associated with the second control signal. The receiving device may receive, over the resource elements of the shared channel and based at least in part on the first control signal, the second control signal identifying second scheduling information for the data transmission. The receiving device may decode the second control signal based at least in part on the first MCS table.

Abstract: Certain aspects of the present disclosure provide techniques for hierarchical communication for device-to-device (D2D) communications. In certain aspects, a method generally includes determining user equipment (UE) data comprising at least one of one or more parameters about the UE, one or more parameters about objects near the UE, or raw sensor data. The method further includes determining a first level for transmitting a first portion of the UE data based on content of the first portion of the UE data. The method further includes determining a first modulation coding scheme associated with the first level based on a mapping of a plurality of levels to a plurality of modulation coding schemes. The method further includes encoding the first portion of the UE data using the first modulation coding scheme and transmitting the first portion of the UE data from the UE to at least one second UE directly.

Abstract: The described techniques may allow transmitting devices to adjust transmission parameters (e.g., transmit power, modulation and coding scheme (MCS)), until reaching an optimal power and/or MCS. These techniques may allow devices to use power efficiently and reduce inter-device interference in a vehicle-to-everything sidelink system. For example, a transmitting device may begin transmissions to a receiving device with initial transmission parameters, which may be configured using a transmission priority and a channel busy ratio. The transmitting device may lower power and/or increase MCS in each of its subsequent transmissions of the same priority, until the receiving device transmits a feedback message that indicates a low signal quality or a failure to decode a previous transmission. The transmitting device may then increase its transmit power and/or decrease its MCS to an acceptable level for a specified time duration based on receiving the feedback message.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.
