Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify two or more peer-to-peer (P2P) communications to be combined based at least in part on a respective location of each of two or more originating UEs from which the two or more P2P communications are received; combine the two or more P2P communications, using network coding, to form a combined P2P communication; and transmit the combined P2P communication. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), such as a pedestrian UE, may perform a discovery procedure with a second UE in a vehicle-to-everything (V2X) wireless communications environment that includes multiple other UEs in addition to the first UE and the second UE. The second UE may, for example, be a roadside UE configured to aggregate V2X messages for the first UE. The first UE may determine, based on performing the discovery procedure, a schedule for the first UE to use to receive bundled V2X messages from the second UE. The first UE may receive, from the second UE based on the determined schedule, a message indicating bundled information from multiple V2X messages received at the second UE from the multiple UEs.

Abstract: Wireless communications systems and methods related to mechanisms to provide physical sidelink feedback channel (PSFCH) negotiation during sidelink connection establishment. A first UE may determine one or more conditions for PSFCH communications via the sidelink session(s) with the second UE. If the second UE accepts the conditions provided, the first and second UEs complete the sidelink connection. Further, while the first UE has a sidelink communication session with the second UE, a third UE may initiate another sidelink connection with the first UE. The first UE may compare the priority of the proposed sidelink connection with the priority of the ongoing sidelink communication session with the second UE. If the second UE's priority is greater, the first UE will maintain the second UE's status. If less, the first UE may engage in a renegotiation with second UE for the ongoing sidelink communication session to update their PSFCH conditions.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may identify a default modulation and coding scheme table and a preconfigured modulation and coding scheme table associated with a resource pool. The UE may receive, from a transmitting communication device, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications. The UE may then communicate based on the preconfigured modulation and coding scheme table.

Abstract: An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving a first timing reference signal and a second timing reference signal at a local device, wherein the second timing reference signal includes an internal timing reference, receiving a timing indication from a remote device, calculating a timing offset from at least one of a propagation delay, the timing indication, or the first timing reference signal, adjusting the internal timing reference based on the timing offset, and transmitting a message based on the internal timing reference.

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 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 ranging are described. A multi-phase distributed ranging technique includes transmitting and receiving vehicle information messages during a first time interval, where the vehicle information messages include at least a vehicle identifier and resource information. The multi-phase technique further includes transmitting and receiving ranging signals during a second time interval, and determining times of arrival of received ranging signals. A centralized ranging technique includes receiving resource assignments from an access point, transmitting ranging signals according to the resource assignments, and determining times of arrival of received ranging signals.

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.
