Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Abstract: This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.

Abstract: Apparatus and methods are provided to for a user equipment (UE) to report channel state information (CSI) to a base station. The UE sends UE capability signaling to a base station to indicate support of a codebook for high speed scenarios. The UE processes configuration information from the base station for CSI reporting using the codebook. The configuration information indicates measurement resources for one or more downlink (DL) channel. The UE measures a channel response and interference using the measurement resources, generates CSI feedback using the codebook for at least one ray from the base station to the UE, and reports the CSI feedback to the base station.

Abstract: A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.

Abstract: In at least one embodiment, a user equipment (UE) may receive a control signal from a base station to update a target pathloss reference signal from an existing pathloss reference signal. In at least one embodiment, the UE may obtain a plurality of samples of the target pathloss reference signal. In at least one embodiment, the UE may determine, based on obtaining the plurality of samples of the target pathloss reference signal, that the UE is unable to update the target pathloss reference signal. In at least one embodiment, the UE may adjust the uplink transmission power of the UE based on the existing pathloss reference signal or to a maximum transmit power based on said determining that the UE is unable to be updated to the target pathloss reference signal.

Abstract: Systems and methods are provided for a user equipment to train a transmit beam of a transmission configuration indication (TCI) for a non-serving cell. A system may use uplink (UL) reference signal (RS) based transmit (Tx) beam training with a target non-serving cell. The Target non-serving cell may measure the UL RS and determine a best Tx beam. The system may coordinate information regarding the best Tx beam to update a TCI at the UE for the target non-serving cell.

Abstract: This disclosure relates to techniques for scheduling multiple downlink transmissions using a single downlink control transmission in a wireless communication system. A wireless device may determine a beam configuration for use for receiving multiple downlink transport blocks scheduled by a single downlink control transmission. In some instances, the wireless device may be configured to skip one or more control channel monitoring occasions that overlap with the downlink transport blocks. The wireless device may provide hybrid automatic repeat request feedback for the downlink transport blocks.
