Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a sidelink synchronization signal and may identify a set of parameters (e.g., cyclic shifts or orthogonal cover codes) that are configured for generating a set of reference signals for transmission within a sidelink broadcast resource based on receiving the sidelink synchronization signal. The UE may transmit, within the sidelink broadcast channel resource, a first reference signal of the set of reference signals that is generated based on applying, to a reference signal sequence, a first parameter of the set of parameters that is orthogonal to a second parameter of the set of parameters that is applied to the reference signal sequence to generate a second reference signal of the set of reference signals.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) that is configured to transmit a message to a neighboring UE via multiple formats, identify a service parameter indicative of a format to be used for the message. The UE may convey information indicating the service parameter from a first layer of the UE to a second layer of the UE, wherein the first layer is an upper layer with respect to the second layer. The UE may generate, by the second layer and based at least in part on the information, the message in the format for communicating with the neighboring UE. Other aspects, embodiments, and features are claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a target user equipment (UE) may receive a channel state information (CSI) reference signal (RS) from a source UE via a sidelink communication; determine that a lower-layer determined source identifier of the source UE is included in a set of upper-layer determined source identifiers; and transmit a CSI report in a media access control (MAC) control element (CE) as a response to the CSI RS, based at least in part on the determination that the lower-layer determined source identifier of the source UE is included in a set of upper-layer determined source identifiers. Numerous other aspects are provided.

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: User equipment (UEs) within a sidelink communications system may employ control forwarding techniques. For example, a UE may piggyback resource reservation information received from other UEs when broadcasting its own resource reservation. A UE that may be in line of sight (LOS) with two other UEs that themselves are in a non-line of sight (NLOS) situation and may include resource reservation information associated with other UEs when broadcasting the control information. For example, when forwarding control information, a UE may identify additional resources available in a transmission interval, and may convey neighbor control information (e.g., known resource reservations of other UEs in the sidelink communications system) using the additional resources. In some cases, the piggybacked resource reservation information associated with the other UEs may be selected based on the amount of additional resources in the transmission interval, a priority of known resource reservation information, etc.

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 are generally directed to vehicle techniques for selecting communication options for vehicle to everything (V2X) type communications. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving one or more parameters for selection of one or more features associated with one or more radio-access technology (RATs), and selecting the one or more features to be used for communicating with one or more other UEs using a V2X communication protocol. The selection of the one or more features may be based on the one or more parameters. The method may also include communicating with the one or more other UEs via the selected one or more features.

Abstract: A device may determine a set of parameters related to a transmission of a packet. For example, a device may determine a transmission range indication for the packet, a Quality-of-Service (QoS) of the packet, or a combination thereof. The device may then determine a resource exclusion parameter related to the transmission of the packet based in part on the set of parameters. Following the determination, the device may transmit, to one or more other devices in a wireless communications system, control signaling including the resource exclusion parameter.

Abstract: Aspects relate to limiting the number of missed reservations by a wireless communication device, such as a vehicle-to-everything (V2X) device. The wireless communication device may calculate a missed reservation metric associated with one or more missed reservations missed by the wireless communication device. The wireless communication device may then limit additional reservations when the missed reservation metric exceeds a missed reservation limit.
