Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for regulating a size of a resource information forwarding message to balance the overhead associated with transmitting the resource information forwarding message with the usefulness of the resource information forwarding message. A first user equipment (UE) may receive a sidelink control information (SCI) message from a third UE indicating resources reserved by the third UE, and it may be appropriate for the first UE to transmit a resource information forwarding message to a second UE indicating the resources reserved by the third UE. As such, the first UE may determine a maximum size of the resource information forwarding message, and the first UE may generate and transmit the resource information forwarding message to the second UE in accordance with the determined maximum size.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing timing for inter-user equipment (UE) coordination to prevent or minimize interference or collisions between sidelink transmissions. A first UE may determine a time window in which to select sidelink resources for an inter-UE coordination message based on a minimum time configured for selecting the sidelink resources. The minimum time configured for selecting the sidelink resources for the inter-UE coordination message may be different from a minimum time configured for selecting sidelink resources for other sidelink messages. The first UE may then select the sidelink resources in the time window for the inter-UE coordination message and transmit the inter-UE coordination message on the selected sidelink resources to the second UE over a sidelink.

Abstract: Using a modulation and coding scheme for a control channel that is more conservative than needed to fulfill the control function may waste resources. To address this issue, a variable size control channel is provided. An apparatus in such a system may be configured to determine an aggregation level of a plurality of aggregation levels associated with a control channel. Each aggregation level of the plurality of aggregation levels is associated with a number of time-frequency resources dedicated for the control channel and a particular modulation and coding scheme used for modulating and coding control information in the control channel. The apparatus is configured to receive control information in the time-frequency resources associated with the aggregation level and decode the control information received in the time-frequency resources associated with the determined aggregation level. The decoding is based on the particular modulation and coding scheme associated with the determined aggregation level.

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: Aspects of the present disclosure provide a method for wireless communications by a peer device. The method generates control information to schedule peer-to-peer communication. The control information includes a first portion with a first set of data and a second portion with a second set of data. The method then transmits the first portion of the control information in a first stage using first time and frequency resources. The first portion indicates a control information format of the second portion. The method further transmits the second portion of the control information in a second stage using second time and frequency resources and the indicated control information format.

Abstract: Certain aspects of the present disclosure provide techniques for reducing inter-vehicle interference. In certain aspects, a method performed by a first vehicle may include detecting a second vehicle is in proximity of the first vehicle, determining that the second vehicle includes an intra-vehicle, obtaining resource allocation information associated with the intra-vehicle network of the second vehicle, the resource allocation information indicating a first set of resources allocated to one or more first sensors of the second vehicle located at least in a first portion of the second vehicle, determining that the first set of resources conflict with a second set of resources allocated to one or more first sensors of the first vehicle located in at least a first portion of the first vehicle, and performing one or more actions to resolve the determined conflict between the first set of resources and the second set of resources.

Abstract: Aspects directed towards network-assisted sidelink scheduling are disclosed. In one example, a scheduled entity receives coverage status information of a peer user equipment (UE), and transmits a coverage status report to a network in which the coverage status report is based on the coverage status information received from the peer UE. The scheduled entity receives a resource scheduling from the network in response to transmitting the coverage status report, and establishes a sidelink communication with the peer UE based on the resource scheduling. In another example, a scheduling entity receives a coverage status report from a UE in which the coverage status report is associated with a peer UE of the UE. The scheduling entity determines a resource scheduling for the UE based on the coverage status report to facilitate a sidelink communication between the UE and the peer UE, and transmits the resource scheduling to the UE.

Abstract: Aspects presented herein may enable vehicle UE(s) to transmit warning message(s) to one or more pedestrian UEs without receiving P2V transmissions from the one or more pedestrian UEs. In one aspect, a first UE determines one or more configuration parameters for a plurality of second UEs, the one or more configuration parameters including an identification parameter, the identification parameter being associated with a time period. The first UE determines, based on the identification parameter for at least one second UE of the plurality of second UEs, whether to transmit a warning message to the at least one second UE. The first UE transmits, based on determining to transmit the warning message, the warning message to the at least one second UE, the warning message including an ID for the at least one second UE, the ID for the at least one second UE being based on the identification parameter.
