Abstract: Aspects described herein relate to determining multiple waveforms for transmitting wireless communications. A control waveform can be determined for transmitting a control information transmission related to a data transmission as one of multiple waveforms. A data waveform can be determined for transmitting the data transmission as one of the multiple waveforms. The control information transmission can be transmitted based on the control waveform, and the data transmission can be transmitted based on the data waveform.

Abstract: Aspects directed towards a network-assisted sidelink scheduling operation are disclosed. In one example, a scheduled entity receives a grant of resources from a scheduling entity operating according to a legacy radio access technology (RAT), and translates the grant of resources from a legacy configuration of resources to a non-legacy configuration of resources. The scheduled entity then performs a sidelink communication via the non-legacy configuration of resources. In another example, a scheduling entity operating according to a legacy RAT transmits a system information block (SIB) to a scheduled entity indicating that the scheduling entity can allocate non-legacy resources. The scheduling entity then receives a request for resources from the scheduled entity that corresponds to a non-legacy sidelink communication, and provides a grant of resources to the scheduled entity that includes a non-legacy-specific frequency for transmitting the non-legacy sidelink communication.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, some user equipment (UEs) may be configured for sidelink communications using a first radio access technology (RAT) (e.g., via a cellular network) and other wireless devices may be configured for sidelink communications using a second RAT (e.g., via a wireless local area network (WLAN)). In order to mitigate interference between communications using the first and second RAT, when a first UE is scheduled to transmit or receive a data transmission on a set of resources using the first RAT, the first UE may transmit a message using the second RAT indicating that the data transmission is to occur on the set of resources. Accordingly, the second device may receive the message and determine to refrain from communicating on the set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a shortened transmission time interval (TTI) to be used for priority communications with a vehicle having a first traffic priority level, the shortened TTI having a duration that is less than that of other TTIs used in other communications with the vehicle having a second traffic priority level less than the first traffic priority level. The UE may transmit a request-to-send (RTS) message during the shortened TTI, the RTS message indicating an identifier and a configuration for the priority communications during the shortened TTI. The UE may receive a clear-to-send (CTS) message from one or more wireless devices participating in the priority communications, the CTS message indicating a sequence associating the CTS message with the RTS message. The UE may perform the priority communications with the wireless devices from which the CTS messages were received.

Abstract: A method, a computer-readable medium, and an apparatus may be a base station configured to receive packets from a plurality of User Equipments (UEs), combine a subset of the packets from the plurality of UEs into a combined packet, and broadcast the combined packet from the base station. In some aspects, a UE may be configured to receive a combined packet in a broadcast from a base station, attempt to decode a plurality of packets combined in the combined packet, and transmit an indication to the base station indicating at least one packet in the combined packet for retransmission. In some aspects, a UE may be configured to generate a packet for relay from a base station, and transmit the packet to the base station with an indication indicating whether the base station should broadcast the packet as a single packet along with broadcasting the packet in a combined packet.

Abstract: Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an example, a first wireless communication device may transmit, to a relay node, a first predicted motion of a first vehicle including the first wireless communication device having a first established communication channel with the relay node. The first wireless communication device may receive an indication that the first predicted motion will trigger a communication condition for the first vehicle and a second wireless communication device having a second established communication channel with the relay node, the indication including reserved resources for a third communication channel between the first wireless communication device and the second wireless communication device. The first wireless communication device may communicate with the second wireless communication device using the reserved resources for a third communication channel without performing a random access procedure with the second wireless communication device.

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: A target user equipment (UE), which may be a vehicle or UE carried by a pedestrian, may receive sequentially broadcast ranging signals from a set of ranging source entities (SEs), which may be road side units or other vehicles. The target UE further receives location information separately broadcast by each SEs. The location information, for example, may include the position for the SE, the time of transmission of the ranging signals transmitted by the SE and/or a sequence identifier for the SE. The target UE may determine ranges to the SEs using time of arrival measurements for the ranging signals and the time of transmissions of the ranging signals or the sequence identifier received in the location information. The position of the target UE may be determined using the determined ranges to the SEs and the positions of the SEs received in the location information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure the reference signal received power (RSRP) of reference signals from other UEs in a time window and exclude resources of transmissions with a measurement which is above RSRP threshold. In some cases, not enough resources are identified, and the UE may increase the RSRP and search for resources again, however the UE may only increase the RSRP until a stop RSRP limit is reached. The UE may increase the RSRP based on an absolute value or a factor of an incremental power value. Once the stop RSRP threshold is reached, the UE may modify the size of the time window, shift the time window, or reduce the number of retransmission of the sidelink message to search for resources for the sidelink message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.
