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 user equipment (UE) of a group of UEs may receive, from a group member of the group of UEs, traffic information including a transmission schedule associated with traffic of the group member UE. The UE may determine a discontinuous reception configuration for the group of UEs based at least in part on the transmission schedule. The discontinuous reception configuration may include a discontinuous reception schedule for the group of UEs. The UE may transmit, to the group of UEs, the discontinuous reception configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of one or more sidelink resources, and the UE may identify wake-up signal occasions associated with the resources. The UE may monitor for wake-up signals during the wake-up signal occasions, and the UE may further monitor the associated set of one or more resources based on receiving a wake-up signal. In some examples, respective sets of one or more sidelink resources may be associated with a number of multiple-input multiple-output layers used for sidelink communications, or may indicate respective bandwidth parts used for monitoring sidelink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

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: A device receives a coded message from a re-transmitting device designated by one or more devices for performing message re-transmission on their behalf. The coded message encodes a first message and a second message, where the receiving device has failed to receive at least the second message. The receiving device further receives a coding-based re-transmission indicator indicating that the coded message is configured as a coding-based re-transmission of two or more previously transmitted messages that are encoded together in the coded message. The receiving device recovers the second message by decoding the coded message. In another aspect, a re-transmitting device is designated by one or more devices for performing message re-transmission on behalf of the devices. The device generates a coded message that encodes a first and a second message; and transmits the coded message and an indicator indicating that the coded message is a coding-based re-transmission.

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: Techniques are described for performing beam sweep procedures as part of a device discovery procedure. A transmitting device (e.g., user equipment (UE) or base station) may generate a discovery preamble that is configured to indicate that a discovery message will be transmitted. The discovery preamble may be a smaller message (e.g., less bits) than the discovery message and thus may use fewer resources when it is being communicated. The transmitting device may transmit a plurality of signals that include a discovery preamble as part of beam sweep procedure. Once the transmitting device identifies a receiving device, the transmitting device may broadcast the discovery message. The discovery preamble may include a variety of different types of information including information relating to an identifier for the transmitting device, a discovery mode of the transmitting device, beam configurations, communication resources, beam sweep indexes, or a combination thereof.
