Abstract: Disclosed are techniques for transmit/receive (TX/RX) beam association in millimeter wave (mmW) vehicle-to-everything (V2X) communications. In conventional wireless systems, a node (e.g., gNB) that manages wireless resources is typically stationary. This means that transmissions from the network node over the same TX beam using the same antenna array orientation can be assumed to be quasi-collocated (QCLed) and communications may be established using fixed-to-mobile beam management approach. However, if the transmitting node is mobile, a quasi-collocation (QCL) assumption may not be valid. To address issues due to mobility of the nodes that manage wireless resources, a mobile-to-mobile beam management approach is proposed.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may iterate a value of a channel access counter (CAC) to a trigger value based at least in part on configuring the value of the CAC. In some aspects, the first wireless communication device may utilize a channel access mechanism to select a set of time-frequency resources for a transmission of a packet based at least in part on iterating the value of the CAC to the trigger value. In some aspects, the first wireless communication device may transmit the packet to a second wireless communication device via the set of time-frequency resources based at least in part on utilizing the channel access mechanism to select the set of time-frequency resources for the transmission. Numerous other aspects are provided.

Abstract: An apparatus may comprise a component for communicating using a first RAT and another component for communicating using a second RAT. Overlapping communication using the two RATs may cause problems for proper reception at the apparatus. The apparatus may detect that transmission or reception of a first packet using a first RAT will overlap in time with reception of a second packet using a second RAT. The apparatus prioritizes the first packet or the second packet based at least on a relative priority of the first packet and the second packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via reflection by one or more passive devices, a first reference signal (RS) that is based at least in part on a shared first key that corresponds to a configuration of the one or more passive devices. The first UE may receive, from the second UE via reflection, a second RS that is based at least in part on the first key. The first UE may generate a second key based at least in part on a measurement of the second RS. The first UE may transmit a positioning reference signal that is based at least in part on the second key and that is associated with a measurement of a range between the first UE and the second UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive link capability information from a second UE that has a cellular wireless connection with a network entity of a cellular wireless network. The link capability information may be associated with a subscription of the second UE to the cellular wireless network. The first UE may establish a local wireless connection with the second UE based on the link capability information associated with the subscription of the second UE to the cellular wireless network. The first UE may communicate one or more messages with the network entity of the cellular wireless network via the second UE using first subscriber identity module (SIM) credentials of the first UE or second SIM credentials of the second UE based on establishing the local wireless connection with the second UE.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE), e.g., such as a pedestrian UE (PUE), may detect, during a first transmission period of a discontinuous transmission cycle, a transmission over a sidelink channel from a second UE that is located within a threshold distance from the first UE, the first UE associated with a first identifier. The first UE may determine, based at least in part on the transmission, a second identifier associated with the second UE, the second identifier being different from the first identifier. The first UE may use, based at least in part on the second UE being within the threshold distance, the first identifier and the second identifier during one or more subsequent transmission periods of the discontinuous transmission cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.
