摘要： This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. A communication system may include a user equipment (UE) that receives a configuration for contention-free random access (CFRA) and a configuration for contention-based random access (CBRA). The UE determines a first random access resource. The first random access resource maps to one or more beams from a target base station. The UE determines a beam quality associated with the first random access resource. The UE initiates a random access request using the CFRA when the first random access resource is a contention-free resource, and the beam quality of the first random access resource is above a threshold beam quality. The UE initiates the random access request using the CBRA when the first random access resource is the contention-free resource, and the beam quality of the first random access resource is below the threshold beam quality.

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 communicates, with a second wireless communication device in a first frequency band, a first system information signal indicating a transmission configuration for a second system information signal 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, the second system information signal based on the transmission configuration.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

摘要： Methods, systems, and devices for wireless communication are described. A base station may configure a first sub-band and a second sub-band of a system bandwidth for communication with a user equipment (UE). The base station may determine a spatial quasi co-location (QCL) relationship between the first sub-band and the second sub-band and may transmit signaling to the UE that indicates the determined spatial QCL relationship. Upon receiving the signaling, the UE may derive, based on the indicated spatial QCL relationship, spatial parameters (e.g., beam width, pointing angle, etc.) for communication with the base station via the second sub-band. The spatial parameters may be derived based on spatial parameters used for reception of a downlink transmission from the base station via the first sub-band. Subsequently, the UE may communicate with the base station via the second sub-band using the derived spatial parameters.

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.

摘要： Methods, systems, and devices for wireless communication are described. The described techniques provide for configuration and transmission of reference signals over aggregated mini-slots by modifying (e.g., extending) transmission time intervals (TTIs) or sharing reference signals across multiple mini-slots. The reference signals may be shared between multiple aggregated mini-slots and a reference signal pattern may be determined based on data payload allocation, modulation coding scheme (MCS), rank, or other factors of the aggregated mini-slots. Data payloads may be scheduled jointly or separately for each mini-slot and may be allocated across a set of aggregated mini-slots.

摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a signal characteristic of a unicast signal is better than a signal characteristic of a broadcast signal; and/or transmit, based at least in part on the determination, a request for an update to a master information block or a minimum system information block to be provided to the user equipment using the unicast signal. In some aspects, a base station may determine that a signal characteristic of a unicast signal associated with a user equipment (UE) is better than a signal characteristic of a broadcast signal broadcasted by the base station; and/or transmit, based on the determination, an update to a master information block (MIB) or a minimum system information block (MSIB) to the UE using the unicast signal. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described that provide for refinement of receive beam beamforming parameters at a user equipment (UE). A UE may transmit two or more signals in an uplink transmission that have different beamforming parameters. A base station receiving the uplink transmission may measure the two or more signals, and identify a first signal of the two or more signals based at least in part on the measuring. The base station may inform the UE of the identified first signal, which the UE may use to set receive beam beamforming parameters for one or more subsequent downlink transmissions.
