摘要： This application provides a communication method and apparatus, which can increase an amount of valid information in a CSI feedback matrix, to help a transmit end to extract attribute information of a target object, and improve a perception capability of the target object. The method includes: A first device receives at least one channel sounding frame from a second device; and determines at least one first CSI matrix H1 based on the at least one channel sounding frame, where H1 indicates a channel state, and the channel sounding frame is in a one-to-one correspondence with H1. Then the first device performs eigenvalue decomposition on a covariance matrix RHH of H2 to obtain an eigenvector matrix U and an eigenvalue matrix Σ, where H2 is determined based on H1, and H2 is a CSI matrix corresponding to any subcarrier. The first device determines, based on H2, U , and Σ, a second CSI matrix V corresponding to H1, and feeds back at least one matrix V corresponding to the at least one matrix H1 to the second device, where the at least one matrix V is used to determine the attribute information of the target object.

摘要： Embodiments of this application disclose a method for constructing an indoor map. The method includes: obtaining a plurality of first tracks and a second track, where each first track is a flat-layer track located on an indoor horizontal layer, the second track is a cross-layer track located between different indoor horizontal layers, and a first wireless signal information similarity between each first track point of the first track and each second track point is less than a first threshold; and performing layering on the plurality of first tracks based on a second wireless signal information similarity between the plurality of first tracks, to obtain a layering result, where the layering result may be used to construct an indoor map. Because wireless signals of the first track points participating in the layering and the track points of the cross-layer track differ greatly, that is, track points near the cross-layer track are not used for layering, tracks on different planes are not incorrectly identified as tracks on a same layer, thereby improving accuracy of track layering.

摘要： The present invention provides a method for handover between access points, and terminal equipment. The method includes: when performing information transmission with a first access point AP on a first frequency band, determining, by the terminal equipment, whether the terminal equipment needs to establish a connection with a second AP, where an operating frequency band of the second AP is a second frequency band; when determining that the terminal equipment needs to establish the connection with the second AP, determining, by the terminal equipment, whether the first AP and the second AP are corresponding to a same dual-band radio access device; when the terminal equipment determines that the first AP and the second AP are corresponding to the same dual-band radio access device, sending, by the terminal equipment, a connection request to the second AP when maintaining a protocol layer connection with the first AP, where the connection request is used to request to establish a connection with the second AP; and if the terminal equipment receives a success message that is fed back according to the connection request and that is sent by the second AP, establishing, by the terminal equipment, the connection with the second AP. In the method, duration required by a process of handover between access points can be reduced, and a user is made not perceive the handover process, thereby improving user experience.

摘要： Embodiments of the present invention provide a batch data query method and apparatus. A data query server determines symbol identifiers of operands in N query statements according to operators and the operands in the N query statements (102), where the symbol identifiers include version numbers of the operands; determines dependency among the N query statements according to the version numbers of the operands in the N query statements (103); and then, performs inter-query optimization on the N query statements according to the dependency among the N query statements and a preset optimization rule (104). The symbol identifiers of the operands in the N query statements are fixed and do not vary with input query statements. Therefore, the determined symbol identifiers of symbol numbers in this method may be applicable to all input sets, any part of any query statement does not need to be executed, and data access and update statuses in a query statement execution process do not need to be monitored, so that inter-query optimization efficiency is improved, and inter-query optimization overheads are reduced.
