摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, via an autonomous uplink communication, one or more transport blocks to a base station. Each transport block may include a plurality of code block groups (CBGs). The base station may provide CBG-level feedback to the UE based at least in part on the autonomous uplink communication. In some examples, the base station may provide the CBG-level feedback in one or more downlink feedback information (DFI) packets. In some other examples, the base station may provide the CBG-level feedback via one or more uplink transmission grants. The UE may retransmit one or more CBGs from the autonomous uplink communication based at least in part on the DFI packets or uplink transmission grants.

摘要： Wireless communications systems and methods related to communications in a network are provided. A first wireless communication device communicates, with a second wireless communication device in a first frequency band, a first downlink (DL) communication signal indicating information associated with a transmission opportunity (TXOP) in a second frequency band different from the first frequency band. The first wireless communication device communicates, with the second wireless communication device in the second frequency band based on the first DL communication signal, a second DL communication signal during the TXOP.

摘要： Wireless communications systems and methods related to communicating random access messages are provided. A method includes communicating, by a first wireless communication device with a second wireless communication device, mode information for determining whether to perform a listen-before-talk (LBT) mode for a random access procedure. The method also includes communicating, by the first wireless communication device with the second wireless communication device, a random access message based on the mode information.

摘要： Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.

摘要： A grant may allocate resources for an uplink transmission by a user equipment (UE) in a system using beamforming, where the resources may be used by the UE to transmit data or control information during a time that a base station is listening in a certain receive beam direction. A UE may be in communication with a base station using beamformed transmissions, and the base station may send a resource grant to the UE for uplink transmissions that correspond to a receive beam direction of a beamsweeping operation. The UE may then transmit data and/or uplink control information to the base station according to the resource grant and when the base station is listening in the corresponding direction. In some examples, the UE may send the uplink transmission to the serving base station, and transmit a random access channel to another base station based on the beamsweeping operation.

摘要： Wireless communications systems and methods related to communications in a network that supports data transmitted in an unlicensed frequency band and a licensed frequency band are provided. A first wireless communication device transmits in a first frequency band, a first system information signal indicating a first random access configuration for a second frequency band. The first wireless communication device transmits in a third frequency band, a second system information signal indicating a second random access configuration for the second frequency band. The first and third frequency bands are different frequency bands. Additionally, the first wireless communication device performs with a second wireless communication device, a random access procedure based on at least one of the first random access configuration or the second random access configuration.

摘要： A method of wireless communication includes receiving, at a user equipment (UE), a grant from a base station on a control channel, the grant including content indicating a mini-slot assigned to the UE. The method may include interpreting the grant based on a current configuration of a data channel to determine the mini-slot. The method may include communicating with the base station during the mini-slot indicated by the grant.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for uplink power control. Certain aspects provide a method for performing uplink power control at a base station (BS). The method includes determining a first configuration of one or more parameters for uplink power control at a user equipment (UE) based on a first spatial beam selected, from a plurality of spatial beams, for uplink communication of the UE. The method further includes transmitting a first indication of the first configuration to the UE.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. According to some aspects, the apparatus may identify a first power state and a second power state, wherein the first power state is associated with a first transmission or reception of one or more first beams, and the second power state is associated with a second transmission or reception of one or more second beams; and/or switch from the first power state to the second power state, wherein the apparatus is configured to use at least one of a scheduled gap or at least one intermediate power state between the first power state and the second power state to smooth a transition from the first power state to the second power state. Numerous other aspects are provided.
