Abstract: Advertising wireless devices (e.g., user equipments (UEs)) within a distributed wireless network may indicate radio frequency and/or baseband capabilities (e.g., via transmitting capabilities messages). A responding UE may receive one or more capabilities messages, and identify radio frequency (RF) capabilities (e.g., indicated via a bitmap) and/or baseband capabilities of the advertising UEs. The responding UE may then determine a transmission scheduling policy based on the one or more received capabilities messages. For example, the responding UE may generate a combined list of frequencies based on the one or more received capabilities messages, and distribute transmissions over the list of frequencies. Additionally or alternatively, the responding UE may determine block decoding baseband capabilities of the one or more advertising UEs, and may accordingly enable block coding schemes for transmissions on frequencies supported by the advertising UEs with such block decoding baseband capabilities.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may identify that a first set of transmission resources in a transmission time interval (TTI) has a higher priority at a second device than a second set of transmission resources in the TTI. The first device may identify that a message is to be transmitted from the first device to the second device via the TTI and process the message into a bit sequence based on the identification of the second set of transmission resources in the TTI, where the processing increases a likelihood that systematic bits of the message are received at the second device despite presence of the second set of transmission resources in the TTI. The first device may transmit the bit sequence to the second device via the TTI.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

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: An apparatus, such as a user equipment or a vehicle, may receive a signal associated with vehicle-to-everything (V2X) communication. The apparatus may determine a total energy that corresponds to the received signal, such as by measuring the energy on one or more resources. The apparatus may determine a fractional energy associated with a first technology of the total energy, such as by detecting a sequence associated with a first technology included in the received signal and determining the energy with which the detected sequence is received. The apparatus may determine presence of a second technology based on the determined fractional energy.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine to use multi-cluster communications in a vehicle based communication network. The UE may identify a configuration parameter associated with the multi-cluster communications. The UE may select a cluster resource from a set of available cluster resources based on the configuration parameter. The cluster resource may include one or more clusters used for multi-cluster transmissions in the vehicle based communication network. The UE may transmit an indication of the selected cluster resource to a wireless node of the vehicle based communication network, for example, to another UE. The UE may transmit the multi-cluster transmission on the selected cluster resource.

Abstract: In an aspect, an apparatus, e.g., a base station of a first network, maybe configured to receive UE capability information from each UE of a plurality of UEs, the UE capability information indicating a number of different carrier synchronization timings that the UE can track within a plurality of carriers. The carriers maybe associated with multiple different networks including the first network. The apparatus maybe configured to determine, based on the received UE capability information, a set of synchronization-timing priorities indicating a priority for timing synchronization types for use within each carrier of a set of carriers of the plurality of carriers, and broadcast the set to the UEs. In an aspect, a UE may determine and send the UE capability to a base station. The UE may receive the set of synchronization-timing priorities and perform timing synchronization based on the received set of synchronization-timing priorities.

Abstract: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices (e.g., in vehicles, fixed structures, or a combination thereof) may selectively share information acquired by the sensor devices. The disclosure relates in some aspects to avoiding redundant transmissions of sensor information. For example, a sensor device of a set of sensor devices may determine which sensor device should transmit information and/or the time(s) at which that sensor device should transmit the information.

Abstract: Methods, systems, and devices are describe for signaling protocols for device-to-device discovery operations in a wireless communication system. A user equipment (UE) may be communicating with a serving base station using a first frequency in a first frequency band. The UE may transmit, to the serving base station, information associated with performing a discovery scan procedure on a second frequency in a second frequency band during a discovery scan interval. The first frequency may be different from the second frequency. The UE may identify a capability to skip one or more downlink transmissions from the serving base station during the discovery scan interval.
