摘要： The present invention relates to a blockchain method relating to geometric objects, a polygon storage method, an electronic device and a computer-readable storage medium. The blockchain token includes geometric data, and the geometric tokens are circulated through transfer, split, and merge. When geometric objects are of polygons representing the lands specified by the geographic location information, it is a suitable as blockchain for recording the transfer of land rights and interests. Except for the token representing the initial geometric objects, if the blockchain system limits all geometric objects in the blockchain to those generated by other tokens through transfers, splits or mergers, each polygon in an unspent token in the blockchain is unique and exclusive. If the initial polygon of the blockchain is one that represents the entire surface of the earth, the blockchain system can be used to record land circulation of the entire world.

摘要： A smart contract method for a blockchain, the method comprising: S1, a node receiving a smart transaction submitted by a user or a block transmitted by another node, wherein the block contains the smart transaction; S2, the node executing all smart contract calls in the smart transaction, and a smart contract adding an input item to the transaction; S3, the node verifying the legitimacy of the smart transaction, which involves verifying the integrity of the transaction after the execution of all the smart contract calls ends; and S4, if a verification result is that the transaction is legitimate, accepting the smart transaction, otherwise, rejecting the smart transaction. A smart transaction is a transaction containing smart contract calls, and the smart transaction can define a user expectation in an output item of the transaction, such that a smart contract provides a suitable input to satisfy a result that a user wants. A miner verifies whether the input provided by the smart contract satisfies the result that the user wants. In the sense of contract law, this is equivalent to verifying whether the intentions of two parties are consistent with each other. Only a transaction that passes verification can be accepted by a blockchain.

摘要： A method of wireless communication by a base station includes receiving a channel state information (CSI) payload at a neural network CSI decoder. The method also includes decoding the CSI payload to generate a quantity (N) of precoding vectors for N transmission layers. The method further includes orthogonalizing the N precoding vectors to generate N orthogonal precoding vectors. The method still further includes transmitting, to a user equipment (UE), downlink data that is precoded in accordance with the N orthogonal precoding vectors.

摘要： A method for wireless communication by a user equipment (UE), includes receiving, from a base station, a reference signal (RS) on a set of resource elements (REs), the RS having been multiplexed onto the set of REs based on a non-orthogonal cover code, and a number of REs in the set of REs being less than a number of ports associated with the RS. The method further includes estimating, at the UE via a channel estimation neural network, a channel based on receiving the RS. The method still further includes transmitting, to the base station, a feedback report associated with the estimated channel based on receiving the RS.

摘要： Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a second wireless node, an indication of an orbital angular momentum (OAM) base value that is associated with one or more OAM modes. The OAM base value may correspond to a number of antenna elements of an antenna ring at the first wireless node, and for each of the one or more OAM modes. Based on the OAM base value, the first wireless node may communicate reference signaling according to the one or more OAM modes using the number of antenna elements of the antenna ring. The second wireless node may use a same number of antenna elements based on the indicated OAM base value.

摘要： The position of a target user equipment (UE) is determined using a set of Reference Signal Time Difference (RSTD) measurements that includes at least three RSTD measurements generated at different times by the target UE. Each RSTD measurement is produced based on positioning reference signals (PRS) transmitted by a stationary anchor entity and corresponding PRS transmitted by a moving mobile anchor entity. At least two anchor-to-anchor receive-transmit (RxTx) time difference measurements are generated by an anchor entity, wherein each anchor-to-anchor RxTx time difference measurement is associated with the RSTD measurements, and there are fewer anchor-to-anchor RxTx time difference measurements than RSTD measurements. The position estimate of the target UE is determined based on the set of RSTD measurements and the at least two anchor-to-anchor RxTx time difference measurements.
