Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. In some aspects, the information indicating the L1-SINR measurement capability may include one or more individual configurations for one or more resources to carry a reference signal. The UE may receive, from the base station, a reference signal carried on the one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

Abstract: A distributed database system may include storage layer. The storage layer may partition data and store the partitioned data in a distributed database. The system may further include access layer. The access layer may receive a transaction, identify target data corresponding to the transaction, and generate a lock request to lock the target data included in the partitioned data. The system may further include lock service layer. The lock service layer may identify, based on the lock request, a lock status for the target data according to a lock record for the target data. The lock service layer may lock, in response to the lock status being in an unlocked state, the target data. The lock service layer may block, in response to the lock status being in a locked state, the lock request and store the lock request in a queue.

Abstract: A method and an apparatus for data processing are provided. Interface circuitry connects the apparatus in a distributed system. Processing circuitry generates first hash values for a first group of virtual nodes to be added into a hash ring. The first group of virtual nodes represents a first newly added device in the distributed system. Then, the processing circuitry distributes the data in the distributed system according to the hash ring that includes the first group of virtual nodes. When the distribution of the data in the distribution system fails to satisfy a uniformity requirement, the processing circuitry identifies a specific virtual node in the first group of virtual nodes that causes the distribution to fail the uniformity requirement. Then, a hash value for a makeup virtual node to replace the specific virtual node is generated to update the distribution of the data in the distributed system.

Abstract: A data storage system may obtain data, a size of the data, and a data structure type of the data. The system may allocate a memory block for the data based on the size of the data and a predetermined block size. The system may store the data in the allocated memory block. The allocated memory block may include a block attribute that includes the data and a head comprising management information corresponding to the block attribute. The management information may include a first block identifier for an antecedent memory block and a second block identifier for a succeeding memory block. The system may link, based on the data structure type, the allocated memory block to a plurality of memory blocks arranged in at least one of a block list structure or a tree structure.
