Abstract: Features of the present disclosure implementing techniques that allow the user equipment (UE) to autonomously (e.g., without the network control) manage timing synchronization of a plurality of carriers using sidelink synchronization signal (SLSS) from one or more other UEs in order to identify a synchronization source. A synchronization source associated with a frequency carrier from a set of frequency carriers may be selected according to one or more SLSS sync source selection techniques or rules. For instance, the described solution may be utilized to enable UEs to autonomously perform V2X carrier aggregation (CA). In some examples, the synchronization carrier(s) to be searched may be determined based on the SLSS capability of the UE (e.g., transmission and reception of SLSS capabilities of the UE).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit concurrent messages over a sidelink channel to another UE and over an uplink channel to a base station. The UE may transmit, to a base station, a report indicating a capability of the UE to concurrently transmit over a sidelink channel and an uplink channel. The UE may receive, from the base station and based on the report, a transmission configuration scheduling a concurrent sidelink and uplink transmission within a resource shared by the sidelink channel and the uplink channel. The UE may then transmit the concurrent sidelink and uplink transmission within the resource shared by the sidelink channel and the uplink channel based on the transmission configuration. The other UE and the base station may receive the concurrent sidelink and uplink transmission and may decode different layers of the transmission.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to the categorization of resources in a system to enable a user equipment (UE) to determine whether resources may be reclaimed. At least two categories may be defined for the resources, and the UE may use various criteria for categorizing the resources in a system. For example, the UE may include a first set of resources in an “available” category and a second set of resources in an “occupied” category. Resources in the “occupied” category may be indicated as occupied by another UE's sidelink channel information. In cases where resources are indicated as reserved for retransmission by another UE, but no feedback is detected, then the UE may use additional parameters to determine whether those resources may be reclaimed for its own transmission and may categorize the resources accordingly.

Abstract: Disclosed are techniques for using ranging signals to determine a position of a pedestrian user equipment (P-UE). In an aspect, a UE receives a plurality of ranging signals transmitted by one or more UEs, measures one or more properties of each of the plurality of ranging signals, and calculates an estimate of the position of the P-UE based on the one or more properties of each of the plurality of ranging signals. In an aspect, the P-UE transmits a plurality of ranging signals, receives a first message and a second message from first and second vehicle UEs (V-UEs), the first and second messages including first and second estimated positions of the P-UE and associated first and second confidences, and calculates an estimate of the position of the P-UE based on the first estimated position, the first confidence, the second estimated position, the second confidence, or a combination thereof.

Abstract: Methods and apparatus for configuring a UE to assist in mitigating network congestion include determining whether a data packet has expired based on a first parameter, which indicates an expiration of the data, and adjusting a transmission of the data packet based on the determination of whether the data packet has expired. In some aspects, the UE may drop the data packet upon determination that the data packet has expired. The UE may be configured detect to a first congestion level, receive a second congestion level from a second UE, and process a frame for transmission based on the first or second congestion level. The UE may be configured determine a priority, generate a data packet that includes a destination parameter or a source parameter, adjust radio resource parameters based on the destination parameter or source parameter, and transmit data packets according to adjusted radio resources.

Abstract: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: Wireless communications systems and methods related to sidelink communications in a TDD system are provided. A first user equipment (UE) may receive from a base station (BS), a time-division-duplexing (TDD) configuration. The first UE may select a first TDD configuration from a set of configured TDD configurations based on the TDD configuration. Additionally, the first UE may transmit to a second UE, an indication of the first TDD configuration. The first and the second UEs may communicate a sidelink communication based on the first TDD configuration. Other features are also claimed and described.

Abstract: A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first kind of synchronization signals from a first synchronization source and may receive a second kind of synchronization signals from a second synchronization source. Additionally, the UE may determine a first priority for the first synchronization source and a second priority for the second synchronization source based on whether each synchronization source is connected to a global navigation satellite system from information in the synchronization signals. Accordingly, the UE may then select the synchronization source with the higher priority and communicate with one or more additional UEs based on synchronizing with the selected synchronization source. In some cases, the first kind of synchronization signals may include sidelink synchronization signals, and the second kind of synchronization signals may include data-based synchronization signals (e.g., demodulation reference signals).
