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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.

Abstract: Additional requirements for spectrum emissions may be matched with regional requirements, and an additional maximum power reduction (A-MPR) for a user equipment (UE) may be based on an actual antenna gain of the UE. For example, a UE may be located in a particular region and be required to meet regional requirements for wireless communications. In such cases, the UE may receive network signaling from a base station, and identify an antenna gain for its antenna. The UE may then identify a set of emission requirements based on the identified antenna gain and the network signaling. Additionally, the UE may identify an A-MPR based on the set of emission requirements and the antenna gain and may adjust a maximum output power in accordance with the identified A-MPR. In some examples, an output power threshold may be derived using a difference between a regional requirement and the UE's antenna gain.

Abstract: Apparatuses, systems, and devices are described for transmissions and retransmissions of device-to-device (D2D) communications. A D2D message may be transmitted during an initial communications period, followed by one or more retransmissions. A device may transmit an initial transmission, determine a time hopping pattern for the retransmission(s), and determine a transmission resource for the retransmission(s) based at least in part on a resource of the initial transmission and the time hopping pattern. The messages may include, for example, a scheduling assignment (SA) for data transmission, or data transmissions from a transmitting device. Time hopping patterns may be determined based on times and/or frequencies of the initial transmission. A base station may transmit a message to a transmitting device that indicates one or more time hopping patterns that are to be used for the transmissions.

Abstract: Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines a channel busy ratio (CBR). The UE determines one or more channel resource utilization limits based on the CBR, wherein each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, each packet of the plurality of packets being associated with a respective packet priority.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message indicating that a base station supports allocating resources for sidelink communications using a first radio access technology (RAT) and a second RAT that is different from the first RAT. The UE may transmit a sidelink information message to the base station using the first RAT that indicates that sidelink communications are to be performed using either the second RAT or both the first RAT and the second RAT. The UE may receive a configuration message from the base station that comprises an identifier for the sidelink communications and an indication of available sidelink resources. The UE may transmit, based at least in part on the configuration message, a request for resources within the available sidelink resources, the request indicating the identifier and a buffer status report (BSR).

Abstract: A transmitting UE may in a device-to-device (D2D) communication may identify a demodulation reference signal (DMRS) sequence for a D2D transmission based at least in part on a subset of bits of a sidelink control information (SCI) transmission. The subset of bits of the SCI transmission may be selected such that the bits have sufficient variability to reduce the likelihood that multiple UEs may use the same DMRS sequence. The subset of bits of the SCI transmission may be all or a portion of a cyclic redundancy check (CRC) for the SCI.
