Abstract: User equipments (UEs) may be configured to perform channel occupancy information multi-access reporting. In some aspects, a user equipment may receive a sidelink configuration message identifying the first UE and one or more other UEs as members of a multicast group and a resource to be used for sidelink communications amongst the multicast group, and receive channel occupancy information (COI) from at least one of the one or more UEs within the multicast group, the COI indicating an occupied condition of the resource determined by the at least one of the one or more UEs during a sensing operation performed with respect to the resource. Further, the UE may select a period of time to transmit a sidelink communication based at least in part on the COI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more transmission parameters based at least in part on an average channel condition estimate for a broadcast channel, wherein the broadcast channel is for broadcast communications or groupcast communications for multiple mobile UEs. The UE may transmit a broadcast communication or a groupcast communication using the one or more transmission parameters. Numerous other aspects are described.

Abstract: A method of wireless communication of a wireless device in a C-V2X connection may include: determining a first WBEE of a symbol at a first bandwidth, the symbol being associated with no expected C-V2X transmissions, determining a second WBEE of the symbol at a second bandwidth, and identifying an interference based on the first WBEE and the second WBEE. The method may also include notifying an operator of the wireless device about the identified interference.

Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a wakeup message to awaken a base station from a sleep mode. The method also includes communicating with the base station after the base station awakens. A method of wireless communications by a base station includes entering a sleep mode when no user equipments (UEs) are connected to the base station. The method also includes receiving a signal from a UE to awaken from the sleep mode. The method further includes resuming signal transmissions after waking up from the sleep mode.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit repetitions of a tracking reference signal to a user equipment (UE). The UE may determine a Doppler frequency for the downlink channel by measuring the repetitions of the tracking reference signal. The UE may transmit an indication of the downlink Doppler frequency to the base station. The base station may determine the uplink Doppler frequency based on the downlink Doppler frequency. The base station may use the uplink Doppler frequency to select an uplink demodulation reference signal (DMRS) configuration for the UE.

Abstract: Interference coordination using over the air data is enabled. A UE receives downlink control information including uplink resource allocation. The UE determines whether it is near a cell edge of its serving cell. If so, the UE echoes at least a subset of the allocation information over the air to one or more neighboring base stations. The echo may use a multi-cluster PUSCH approach or a combined PUSCH, PUCCH approach. One or more neighboring base stations receive the echoed allocation data. With the echoed data, the neighboring base stations engage in interference coordination, thereby avoiding delays inherent in non-idea backhaul connections. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method of wireless communication at a user equipment (UE) includes receiving a first collision report (s), each first collision report indicating at least one first monitored subset of sidelink resources that were monitored by a remote sidelink UE. The method also includes transmitting a second collision report indicating allocation collisions detected by the UE on a second monitored subset(s) of sidelink resources. Each of the second monitored subset(s) of sidelink resources differing from each of the first monitored subset(s) of sidelink resources indicated in the received first collision report(s). The second collision report further comprising an indication of each of the second monitored subset(s) of sidelink resources.

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) autonomous sidelink resource selection. A method that may be performed by a UE includes performing autonomous sidelink resource selection. The selection includes excluding resources, from a first resource set, associated with transmissions at a signal strength above a signal strength threshold to form a second resource set. The selection includes determining a resource amount in the second resource set is at or above a threshold percentage of a resource amount in the first resource set. The selection includes excluding, from the second resource set, resources associated with physical sidelink control channels (PSCCHs) without excluding resources associated with physical sidelink shared channels associated with the PSCCHs to form a third resource set. The selection includes randomly selecting resources for a PSCCH transmission from the third resource set. The method includes sending the PSCCH transmission using the randomly selected resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may communicate, with a second wireless device, a first set of messages of a first message type that are acknowledged according to an acknowledgement procedure. The first wireless device, the second wireless device, or both may select a first subset of messages of the first plurality of messages and a first subset of bits from each message of the first subset of messages based on the first set of messages being acknowledged and according to a sampling configuration common to both the first wireless device and the second wireless device. The first wireless device, the second wireless device, or both may generate a key using bit values of the first subset of bits from each message of the first subset of messages, encoding a message using the key, and communicate the encoded message.
