Abstract: Methods, systems, and apparatuses are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, content of an MBMS may be received while operating in a coverage area of a base station. A transition to operate outside the coverage area of the base station may be sensed. A peer discovery signal to request a relay of the content of the MBMS may be transmitted. The peer discovery signal may include an identifier of the MBMS. In another configuration, a first peer discovery signal including an out-of-coverage status indicator for the mobile device or MBMS query and an identifier of an MBMS may be received from the mobile device. A determination may be made regarding whether to relay content of the MBMS. Upon determining to relay the content of the MBMS, a second peer discovery signal indicating a capability to relay the content of the MBMS may be transmitted.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, some user equipment (UEs) may be configured for sidelink communications using a first radio access technology (RAT) (e.g., via a cellular network) and other wireless devices may be configured for sidelink communications using a second RAT (e.g., via a wireless local area network (WLAN)). In order to mitigate interference between communications using the first and second RAT, when a first UE is scheduled to transmit or receive a data transmission on a set of resources using the first RAT, the first UE may transmit a message using the second RAT indicating that the data transmission is to occur on the set of resources. Accordingly, the second device may receive the message and determine to refrain from communicating on the set of resources.

Abstract: Various aspects of the disclosure relate to limits for modulation and coding scheme (MCS) values. For example, a first set of limits (e.g., minimum and maximum limits) may be used for a first MCS table and a second set of limits may be used for a second MCS table. The disclosure also relates in some aspects to inter-device signaling that indicates which minimum and maximum limits for an MCS table are to be used for communication between the devices.

Abstract: Techniques are described for wireless communication at a wireless device. One method includes transmitting, during a TTI, a first message using a first MCS; and transmitting, during the TTI, a second message using a second MCS. The first message includes indications of a location, a heading, and a speed of the wireless device, and the second MCS is higher than the first MCS. Another method includes decoding a first message received during a TTI; performing a Doppler effect compensation for a second message based at least in part on the first message; and decoding the second message based at least in part on the Doppler effect compensation. The second message is also received during the TTI. The first message is decoded in accordance with a first MCS, and the second message is decoded in accordance with a second MCS, with the second MCS being higher than the first MCS.

Abstract: Various aspects of the present disclosure relate to vehicle-to-vehicle (V2V) data sharing. The sensor data collected from each vehicle may be divided into common information and detailed information. The common information is broadcasted to every other nearby vehicle. Based on the received common information other vehicles may express interest in some particular detailed information. Unicast and/or multicast sessions may be set up to share the detailed information with the interested vehicles.

Abstract: Aspects of the disclosure relate to a vehicle, or a device or system connected to the vehicle, that enables the vehicle to act as a base station in a wireless communication network. The vehicle includes an access interface transceiver configured to communicate with devices within its passenger cabin, and a backhaul interface transceiver configured to communicate with the wireless communication network. By acting as a base station, the vehicle can establish and provide connectivity between the devices in its passenger cabin and the wireless communication network via the access transceiver and backhaul transceiver.

Abstract: Aspects of the disclosure relate to beamforming from a vehicle user equipment (UE). In a first aspect, a beamform vector is selected based on beamform data received from a scheduling entity. Here, the beamform data corresponds to a path between a vehicle UE and a base station or another vehicle, and the beamform vector includes respective phases and amplitudes corresponding to each of a plurality of antennas of the vehicle UE. A beam is then generated in accordance with the beamform vector. In another aspect, a database of beamform data is maintained, and beamform data from the database is retrieved. Here, the retrieved beamform data corresponds to a particular location pair that includes a first location associated with a location of a vehicle UE, and a second location associated with a location of a base station or another vehicle. The beamform data is then transmitted to the vehicle UE.

Abstract: Methods, systems, and devices are described for managing a multimedia broadcast multicast service (MBMS). In one configuration, service announcement information for at least one MBMS may be received. At least a subset of the service announcement information may be broadcast in a peer discovery signal. Content of the at least one MBMS may then be relayed to at least one mobile device operating outside a coverage area of a base station. In another configuration, an out-of-coverage status indicator or MBMS query may be broadcast in a first peer discovery signal, and a second peer discovery signal may be received from at least one MBMS relay device. The second peer discovery signal may include at least a subset of service announcement information for at least one MBMS.
