摘要： Aspects of the present disclosure propose a mechanism whereby a nearby device may detect scenarios where one device is unable to receive communications from a transmitting device. For example, the nearby device may detect that concurrent transmissions of a transmitting device and intended recipient prevent reception by the intended recipient and provide feedback to the transmitting device. Rather than blindly retransmitting, the transmitting device may only retransmit when it receives feedback from the nearby device, saving power and avoiding unnecessary transmissions.

摘要： Aspects described herein relate to managing coexistence of multiple radio access technology (RAT) components in a device. Information related to an upcoming time period can be sent to a first radio access technology (RAT) component from a second RAT component. The first RAT component can select a resource to transmit a first RAT packet to minimize collision with the upcoming time period of the second RAT.

摘要： Methods, systems, and devices for wireless communications are described. A device, which may be otherwise known as user equipment (UE) may support sidelink communications, for example, such as device-to-device (D2D) communications, vehicle-based communications, which may also be referred to as vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, and the like. To mitigate or decrease collisions or other interference on resources (e.g., time and frequency resources) used by other UEs in sidelink communications, a UE may determine a blind retransmission of a packet, determine that the packet satisfies one or more conditions based in part on the blind retransmission, and transmit feedback signal relating to the blind retransmission of the packet.

摘要： Aspects of the disclosure relate to methods for wireless communication. A transmitting device transmits a first portion of a control message to a receiving device. The first portion includes information for decoding a second portion of the control message and for decoding data. The transmitting device then transmits the second portion to the receiving device, the second portion including additional information for decoding the data. Thereafter, the first device transmits the data to the receiving device. The receiving device receives the first portion and the second portion, and decodes the received second portion based on the information included in the first portion. The receiving device then receives the data from the second device if the received second portion is able to be decoded. The receiving device decodes the received data based on the information included in the first portion and the additional information included in the second portion.

摘要： Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may establish a unicast connection over a sidelink communications with a second UE. To establish the unicast connection over the sidelink, the first UE may transmit a request message (e.g., a first message) to the second UE, and the second UE may transmit a response message (e.g., a second message) to the first UE accepting the request. The unicast connection over the sidelink may be established between the first UE and the second UE, and user data may then be transmitted over the sidelink on the established unicast connection. Additionally, the first UE may transmit a connection complete message (e.g., a third message) to the second UE indicating that the unicast connection has been established. The request message, the response message, and the connection complete message may be radio resource control (RRC) messages.

摘要： Aspects of the present disclosure provide techniques for utilizing road side unit (RSU) that may be stationary units or mobile user equipments (UEs) (e.g., part of a vehicle) for managing scheduling requests from one or more UEs for side-link cellular vehicle-to-everything (CV2X) communication between UEs. To this end, an RSU may determine characteristics associated with the scheduling requests (e.g., traffic type, latency requirements, etc.) to allocate resources in the resource pool to the one or more UEs that comply with the half-duplex constraints.

摘要： Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may identify a first indicator identifying a number of multi-user multiple-input/ multiple-output (MU-MIMO) stations associated with a first resource unit (RU) in a first content channel of a transmission frame. The transmitter may generate a first common portion of a WLAN signaling field in the first content channel. The first common portion may include the first indicator. The transmitter may identify a second indicator identifying an absence of MU-MIMO stations associated with a second RU in a second content channel of the transmission frame. The transmitter may generate a second common portion of the WLAN signaling field in the second content channel. The second common portion may include the second indicator. The transmitter may transmit the transmission frame including the WLAN signaling field.

摘要： Techniques are described for wireless communication. One or more wireless local area network (WLAN) preamble portions may span multiple 20 MHz frequency bands, and may be duplicated across a transmission bandwidth. WLAN preamble portions may include common portions for multiple receivers as well as dedicated portions for particular receivers, and common portions may be transmitted in a primary frequency band in some examples. Some techniques provide that WLAN preamble portions may be encoded using different sized code blocks. Various aspects of the disclosure also provide for signaling of resource allocations of WLAN wireless frames.
