Abstract: A pedestrian-located UE monitors selected subframes of a sidelink resource to detect periodic transmissions from other mobile devices to assist it in selecting a free resource for its own sidelink transmissions. The subframe selection is based on a cost metric which takes into account a probability of missing detection of a transmission with periodicity p from another mobile device, an average number of transmissions with periodicity p that are expected from another mobile device within a predefined transmission period of the mobile device, and a number of transmission cycles of the mobile device that need to occur in order to have a single potential collision with each periodic transmission from said at least one other wireless communication. The method provides a trade-off between avoiding future collisions and battery life.

In response to the first device not receiving a beacon packet from the other devices during the random back off period, the first device initiates an election protocol by sending an election protocol packet with its unique election protocol identifier to the other devices. In response to receiving a beacon packet from a second device, the first device stores the unique node identifier, assigns the second device as a leader node device, retransmits the unique node identifier of the second device and leader node information in a protocol packet. A command packet is communicated through the mesh network by way of at least one leader node device.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, phase-noise compensation tracking signals (PTRS) may be transmitted using sets of resource blocks (RBs), where a frequency for each PTRS within the sets RBs is different from a frequency corresponding to a direct current (DC) tone. In another example, a time-domain-based PTRS may be used, where a discrete Fourier transform (DFT)-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) symbol may include a cyclic prefix and a PTRS inserted in the DFT-s-OFDM symbol. Additionally or alternatively, a guard-interval-based DFT-s-OFDM symbol may include a PTRS that replaces part or all of a guard interval. In some examples, subsets of tones used for PTRS across a system bandwidth may be transmitted using a scrambled modulation symbol, where at least one antenna port may be used for the transmission of PTRS.

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.
