Abstract: The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Abstract: Methods, systems, and devices for wireless communication are described to support security techniques for ranging in wireless networks. A first device may transmit an indication to initiate a ranging procedure with a second device, and in response to the indication, the second device may transmit signaling to the first device and to one or more third devices. The first device and the one or more third devices may each determine a respective location metric associated with the second device based on the signaling. The one or more third devices may each transmit, to the first device, the respective location metric. Based on the communicated location metric(s), the first device may determine whether an eavesdropper is present and may communicate with the second device based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive, from a network entity, a control message for a radar reference signal (RRS) configuration associated with the wireless device. The wireless device may set a timing pattern for the RRS based on the control message and one or more timing parameters for the RRS configuration. The wireless device may transmit the RRS according to the timing pattern. The RRS may include one or more cyclic prefix (CP) sub-symbols and one or more RRS sub-symbols. The wireless device may receive one or more reflections of the RRS and may perform one or more processing operations on the one or more reflections of the RRS using a plurality of sampling windows. A quantity of sampling windows may be equal to a quantity of CP sub-symbols.

Abstract: Methods, systems, and devices for wireless communications are described to support transmitting a network coded combined message to a second wireless device that may have missed at least one sidelink message included in another network coded combined message. A first wireless device may identify that the sidelink messages are configured for network coding based on information associated with the sidelink messages. Control information associated with the network coded combined message may indicate that the network coded message is a network coded combined retransmission of the sidelink messages, and may further include information identifying the sidelink messages and devices that transmitted the sidelink messages. The first wireless device may combine the sidelink messages into the network coded combined message and may transmit the control information and the associated network coded combined sidelink message to the second wireless device, which may support decoding of one or more missed sidelink messages.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit compressed bitmap(s) to indicate preferred or non-preferred sidelink resources. A first UE may monitor a set of sidelink resources including a set of slots and subchannels for the slots and determine which resources are available for communications for a second UE. In some examples, the first UE may generate a bitmap indicating which slots have at least one subchannel that is unavailable, and, for each slot having at least one subchannel that is unavailable, a bitmap indicating which subchannels are unavailable for that slot. The first UE may transmit the bitmaps to the second UE. In some examples, the first UE may generate a bitmap indicating which slots have at least one subchannel that is available, and, for each slot having at least one subchannel that is available, a bitmap indicating which subchannels are available.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a device-to-device communication with another UE, a modulation and coding scheme (MCS) configuration, of a set of MCS configurations, based at least in part on at least one of a transmission mode, a packet characteristic, a mobility state of the UE, a capability of the UE, a transmission mode of the device-to-device communication, a received indication from the other UE, or a combination thereof. The UE may transmit, to the other UE, data using an MCS selected based at least in part on the MCS configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may transmit a wireless in-vehicle network (wIVN) capability indication that indicates that the UE is associated with a vehicle that includes a wIVN; receive a response to the wIVN capability indication from another UE; and provide configuration information to a wIVN control unit of the vehicle associated with configuring the wIVN based at least in part on the response. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) such as a vehicle may identify data for transmission and transmit a request message to one or more receiving UEs (e.g., other vehicles). The request message may be associated with a first priority. The transmitting UE may monitor resources for a response message. The response message may be associated with a second priority. If the transmitting UE receives a response message, the transmitting UE may determine whether to transmit the data based on a comparison of the priorities of the request message and the response message. In some cases, the transmitting UE may transmit the data if the transmitting UE does not receive any response message. A receiving UE may receive the request message and determine whether to transmit a response message based on the priority and/or the receive power of the request message.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.
