Abstract: Aspects relate to mechanisms for sidelink reservation across frequency bands. In some examples, a sidelink device may be configured to communicate over a first frequency band (e.g., a sub-6 gigahertz frequency band) and a second frequency band (e.g., a millimeter wave frequency band) with one or more other sidelink devices. The sidelink device may further be configured to perform cross-link resource reservation for a sidelink transmission in which a resource reservation message transmitted on the first frequency band indicates reserved resources within the second frequency band for the sidelink transmission. The sidelink device may then transmit sidelink control information (SCI) within a sidelink control channel on the second frequency band and user data traffic corresponding to the SCI within a sidelink data channel on the second frequency band.

Abstract: An apparatus for wireless communication of a UE determines to transmit data in a set of RBs to at least one other UE in at least one subframe. The at least one subframe includes a first subset of symbols configured for use for transmission collision avoidance signaling and a second subset of symbols configured for transmitting the data. The apparatus determines a subset of symbols of the first set of symbols within the set of RBs of the at least one subframe for transmitting at least one concatenated sequence. The apparatus transmits the at least one concatenated sequence in each symbol of the determined subset of symbols within the set of RBs of the at least one subframe to indicate that the data will be transmitted in the second set of symbols within the set of RBs of the at least one subframe.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS) in communications by a wireless communications device. A packet from an application generated for a first radio access technology (RAT) can be obtained, where the packet includes a first QoS value associated with the first RAT, and/or the first QoS value can be mapped to a second QoS value associated with the second RAT. In another example, the QoS value can be indicated in the packet along with a reflective indicator indicating to use the QoS value in transmitting a response to the packet.

Abstract: Aspects described herein relate to sidelink-assisted virtual multi-link. In one aspect, for example, a relay node may serve as an additional virtual antenna panel for a UE by receiving downlink data from a base station via an access link, or receiving uplink data from the UE via a sidelink. The relay node may forward the downlink data to the UE via sidelink, or the uplink data to the base station via the access link. In another aspect, a base station may determine, for a UE, quasi-colocation (QCL) information and a grant for one or both of one or more access link resources or one or more sidelink resources. The base station may further transmit, to the UE, the QCL information and the grant on a downlink communication channel.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.

Abstract: Aspects of the present disclosure describe indicating per-packet quality of service (QoS). A first packet can be obtained, by a wireless communications device, from an application generated for a radio access technology (RAT), where the first packet includes a QoS value associated with the RAT. A reflective indicator can be set in a header of the first packet to indicate a configuration, including a QoS value, to be used by a receiving device in transmitting a second packet. The first packet can be transmitted to the receiving device.

Abstract: Various aspects described herein relate to techniques for connection setup procedures in a wireless communication system (e.g., a vehicle-to-everything (V2X) communication system in millimeter wave). In an aspect, the method includes identifying information for V2X communications, and initiating a random access procedure based on the identified information. The method further includes identifying one or more random access channel (RACH) resources based on the information, identifying one or more RACH response resources based on the one or more RACH resources, and performing directional communications using at least the one or more RACH resources or the one or more RACH response resources.
