Abstract: Methods, systems, and devices for wireless communication are described. In an FDD system, a UE may identify an indicator associated with ultra-reliable low latency communications (URLLC) while communicating in a sidelink channel. The UE may also identify dedicated uplink resources in the sidelink channel, and reserve the dedicated uplink resources. The dedicated uplink resources may be reserved for an acknowledgement/negative acknowledgement (ACK/NACK) feedback or for a scheduling request (SR). URLLC data may be communicated, and the reserved uplink resources may be utilized to transmit an ACK/NACK feedback or a SR. In a TDD system, a base station may transmit information identifying dedicated resources for URLLC data. In some cases, a base station may transmit an indicator channel, which a sidelink UE may monitor to determine the presence of URLLC data, and respond accordingly.

Abstract: A base station may transmit, to a user equipment (UE), an indication of parameters (e.g., thresholds) for radio link monitoring (RLM). The UE may monitor active beam pairs in accordance with the indication. In some cases, the UE may configure or may be configured (e.g., by a base station) to transmit reference signals for triggering an RLM operation based on the monitored beam pairs. After triggering, the base station may perform an RLM operation with the UE. Additionally or alternatively, a base station may configure a UE with a beam monitoring configuration that enables uplink beam monitoring. The configuration may indicate one or more active beam pairs for uplink transmissions from the UE, and the base station may perform an RLM operation on the indicated beam pairs. Based on RLM operations (e.g., joint uplink and downlink beam monitoring), beam pairs may be reestablished or newly established.

Abstract: The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may identify resource blocks (RBs) used to transmit data in a data transmission. The transmitting device may determine a frequency width of a data channel in a frequency domain that is used to transmit the data based at least in part on the identified RBs. The transmitting device may dynamically determine an allocation of RBs used to transmit control information in a control channel. The allocation of RBs may be based on the frequency width of the data channel and may cause a frequency width of the control channel to match the frequency width of the data channel in the frequency domain. The transmitting device may transmit the control information in the control channel to indicate a location of the data channel.

Abstract: Various aspects of the disclosure relate to a request-response mechanism for sharing sensor information. For example, sensor devices (e.g., in vehicles, fixed structures, or a combination thereof) may selectively share information acquired by the sensor devices. The disclosure relates in some aspects to avoiding redundant transmissions of sensor information. For example, a sensor device of a set of sensor devices may determine which sensor device should transmit information and/or the time(s) at which that sensor device should transmit the information.

Abstract: Methods, systems, and devices for wireless communication are described that provide for selecting different uplink transmission parameters for transmission or retransmission of a random access message. A user equipment (UE) may retransmit a random access message to a base station during a random access procedure if an initial transmission of the random access message was unsuccessfully received by the base station. The UE may select a different transmission beam, uplink resource, or transmission power for retransmission of the random access message. The selection may be based on path loss associated with synchronization signals or previous transmissions. The selection may also be based on a maximum number of retransmissions.

Abstract: Techniques are described for backhaul operations in a millimeter wave wireless communication system. A first base station of the millimeter wave wireless communication system identifies an access demand and one or more access communication parameters associated with the first base station. The first base station sends information to a second base station indicative of the access demand and the one or more access communication parameters, and determines one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system. The first base station establishes a wireless backhaul link with the second base station via the millimeter wave wireless communication system. The first base station partitions resources between an access link with one or more user equipments and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the backhaul communication parameters.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit, using a first base station beam, a first message to a user equipment (UE). The first message may include a pre-grant communication and a plurality of downlink beam refinement reference signals (D-BRRSs). The base station may receive a second message from the UE in response to the first message. The second message may include a pre-grant acknowledgement and a plurality of uplink beam refinement reference signals (U-BRRSs). The base station may transmit, using a second base station beam, a third message to the UE. A width of the second base station beam may be less than a width of the first base station beam.

Abstract: Wireless communications systems and methods related to transmission of platoon information. A first vehicle in a vehicle platoon obtains a first radio resource spanning a frequency channel and a time period for synchronous transmission with at least a second vehicle in the vehicle platoon. The first vehicle transmits, synchronously with at least the second vehicle, information associated with the vehicle platoon in the frequency channel and the time period of the first radio resource. The first vehicle may obtain the first radio resource by requesting a transmission request from a wireless communication device and receiving a transmission grant indicating the first radio resource. Alternatively, the first vehicle may obtain the first radio resource by selecting the first radio resource based on at least one of a sensing report or a resource reservation received from the second vehicle.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The apparatus may receive a message from a base station. The message may indicate a first dedicated resource for downlink transmission, and the first dedicated resource may be associated with a scheduled downlink transmission from the base station. The apparatus may determine a second dedicated resource for uplink transmission based on the first dedicated resource for downlink transmission indicated in the message. The second dedicated resource for uplink transmission may be associated with the scheduled downlink transmission. The apparatus may determine whether to transmit an information message, to be used by the base station for transmitting the scheduled downlink transmission, on the second dedicated resource.
