Abstract: Wireless devices in a wireless network may use multiple communication modes to perform device-to-device (D2D) communication in a mesh wide area network (WAN). For instance, one communication mode may be contention-based, while the other communication mode may be scheduled (e.g., by a relay). To facilitate co-existence between these communication modes, a wireless device may identify a set of resources set aside for D2D communications and may select and reserve a transmission time interval (e.g., a slot) of the D2D resources. Other wireless devices may determine the transmission time interval is reserved and refrain from transmitting during that transmission time interval. In another example, a base station may assign a D2D communication mode to certain sets of D2D resources.

Abstract: Methods and apparatuses are provided which may be used in a base station and/or user equipment (UE) to support or otherwise provide device-to-device (D2D) communication in a shared radio frequency spectrum between candidate UEs. For example, a base station may determine that a first UE and a second UE are candidates for D2D communication, and provide and indicate that a Grant-free Uplink (GUL) resource allocation for D2D communication between the first and second UEs. The base station may further monitor the D2D communication.

Abstract: Wireless communication systems and methods related to the discovery and selection of relay devices by internet of everything (IoE) devices are disclosed. For example, IoE devices with low pathloss to a base station can broadcast information during discovery frames that allow other IoE devices to discover them and select them as a relay, if appropriate. The discovery broadcast message from an IoE device can include information to allow a listening IoE device to select a suitable IoE device for relaying its data that satisfies latency parameters while minimizing the energy impact of relaying. Signaling structures are also provided to allow different IoE devices to select slots for broadcasting within the discovery frame in a distributed manner without disrupting existing periodic broadcasts. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the disclosure relate to back-off mechanisms for fair joint access of an unlicensed sidelink channel. Each sidelink device may perform independent and asynchronous listen before talk (LBT) of the unlicensed sidelink channel with a respective back-off timer initialized with a back-off value selected to provide fair access to the unlicensed sidelink channel by both active sidelink devices and other devices utilizing the unlicensed sidelink channel. In some examples, the back-off value may be selected based on an estimated number of active sidelink devices. The estimated number of active sidelink devices may be determined, for example, by monitoring distributed handshake signaling on the unlicensed sidelink channel.

Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices may include receiving control information from a serving station, synchronizing with an end device based at least in part on the control information received from the serving station, and receiving an acknowledgement (ACK) from the end device in response to the synchronizing, the ACK indicating the end device is synchronized with the relay device. The methods, systems, and devices may also include receiving a data packet from the end device subsequent to the synchronizing, and transmitting, to the serving station, the data packet received from the end device, the transmitting based at least in part on the control information received from the serving station.

Abstract: IoE devices signal association requests to relay devices during association slots. An IoE device receives a discovery broadcast from a relay device, listing available tones for association. The IoE device sends a first association request to the relay device using a tone selected from the list. The relay device returns a first response. The IoE device randomly selects a tone from a channel and sends a second request to the relay device with it. A second response is sent to the IoE device after contention. The IoE device creates a list of available tones and sends it to the relay device. An overlapping tone is selected. The relay device sends the selected tone to the IoE device for subsequent data communication. If there is no overlap, the relay device may suggest available tones for use in a subsequent association request. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.

Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a grant to a first user equipment (UE) that indicates a resource allocation for a sidelink communication, either from the first UE to a second UE or from the second UE to the first UE. The grant may include a destination identifier associated with the sidelink communication, as well as a mapping between the resource allocation and the destination identifier. The destination identifier may be based on information in an indication received from the first UE. In some examples, the base station may configure a default receiver UE for transmissions from the first UE, and the base station may identify a receiver UE in the grant if the intended receiver UE is different than the default receiver UE.
