The location management network element determines a location of the terminal device based on location information of the network device, location information of the reflection panel, and the measurement result. In response to a line-of-sight (LOS) path between the terminal device and the network device being blocked, a signal on the LOS path cannot be directly transmitted and measured.
In an embodiment, a session management function (SMF) network element obtains first information identifying a data stream, where the first information is used to instruct a transmit end to send a user stream using the data stream and to instruct a receive end to receive the user stream using the data stream; and the receive end is an access network element, and the transmit end is a user plane function network element, or vice versa; the SMF network element sends the first information to the user plane function network element and/or the access network element; the SMF network element obtains second information, where the second information is used to indicate a forwarding rule of transmitting the user stream by the user plane function network element on a data network side; and the SMF network element sends the second information to the user plane function network element.
A GAN training method, a machine learning system, and a communication apparatus are provided, which relate to the field of communication technologies and AI. The machine learning system includes a first device and a second device, where a first GAN runs on the first device, a second GAN runs on the second device, the first GAN includes a first generator and a first discriminator, and the second GAN includes a second generator and a second discriminator.
A method and/or a communications apparatus controls a monitoring of a physical downlink control channel. The method includes: receiving, by a terminal device, a first message sent by a network device, where the first message includes M sleep time sets, and the sleep time is used to indicate a time length in which monitoring the PDCCH is stopped; receiving, by the terminal device, a second message sent by the network device, where the second message includes sleep time indication information, the sleep time indication information is used to indicate a target sleep time index, and the target sleep time index is an index in the M sleep time sets; and stopping, by the terminal device, monitoring the PDCCH in a target time period.
An apparatus and method for computing multiplication operations involving vectors, matrices or both, using a photonic computing architecture including an optical crossbar array. A compensation device is used to compensate for non-ideal characteristics of devices in the optical crossbar array. Apparatus and methods for representing negative-valued vectors of a multiplier in the multiplication operation are also provided.
