Abstract: Techniques described herein leverage existing localization sensors or V2X devices to detect one or more other vehicles that include wireless systems that can interfere with in-vehicle wireless networks. The localization sensors or V2X devices can provide information to determine a location, a heading, a speed, a size, and a type of other vehicles. This information can be used to determine a probability of network interference and allow the in-vehicle wireless networks to employ one or more techniques to mitigate the effects of the interference. The interference mitigation techniques can include increasing or decreasing transmitter power, changing a frequency or a channel of a wireless transmitter, or activating one or more additional transmitters as relays to improve reliability.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure resources on a first communication link for scheduling requests and may transmit an indication of the configured resources over a second communication link to a first device. The first device may relay the indication of the configured resources to a second device via the first communication link. The second device may identify that resources on the first communication link are unavailable for a transmission and may transmit a scheduling request. The first device may receive the scheduling request. The first device may transmit, over the first communication link and based on the scheduling request, an indication of one or more shared channel resources configured by the base station for the transmission. The first device may receive, over the first communication link, the transmission over the one or more shared channel resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.

Abstract: Methods, systems, and devices for wireless communications are described to support relayed sidelink communications. A first device and a base station may communicate via a communication link including a sidelink link between the first device and a second device and a relay link between the second device and the base station. The base station may determine restrictions for the communication link and transmit an indication of the restrictions over the relay link. The restrictions may differentiate data originating from the first device and the second device, restrict the first device to one or more resources, or associate logical channels at the first device with one or more transport block sizes and communication links. The second device may relay the indication of the restrictions to the first device. The first device, the second device, and the base station may communicate over the communication link according to the restrictions.

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.
