Abstract: This application provides a method for obtaining downlink channel information. The method includes: performing preceding weighting on M CSI-RSs of each of N sub-cycles, where each sub-cycle is a quantity of measurement pilot subframes for bearing and transmitting the M CSI-RSs; sending the M weighted CSI-RSs to UE; receiving M PMIs and M CQIs that are sent by the UE and that correspond to the M CSI-RSs, where the M PMIs and the M CQIs are obtained by the UE by separately measuring the M weighted CSI-RSs based on a set a rank 1 preceding codebooks corresponding to the predetermined antenna quantity; obtaining M signal-to-noise ratios of a downlink channel of the UE according to the M CQIs, obtaining M equivalent codebooks according to the M PMIs and weights of the preceding weighting; and obtaining a covariance matrix according to the M signal-to-noise ratios and the M equivalent codebooks.

Abstract: A foldable apparatus is provided. The foldable apparatus includes a first foldable part, a middle bending part, and a second foldable part that are connected in sequence. The first foldable part and the second foldable part can rotate relative to each other based on the middle bending part. A first wireless communication chip is disposed in the first foldable part. A second wireless communication chip is disposed in the second foldable part. In the foldable apparatus, wireless communication is used to replace conventional physical wiring for internal signal transmission. The loss of a communication carrier is reduced through wireless communication. This ensures that stable transmission performance between the first foldable part and the second foldable part.

Abstract: A device fault processing method is used to perform fault processing on a peripheral component interconnect express device. The method includes: obtaining, by the controller, first device fault information after detecting that the device is faulty, where the first device fault information is used to indicate that the device is faulty, the first device fault information includes a first value of a fault processing state parameter of the device, and the first value indicates that the device is in a soft reset state; and performing, by the controller, hot reset processing on the device, so as to implement fault processing on the peripheral component interconnect express device without manual intervention in plugging out and plugging in or resetting a pluggable unit in which the peripheral component interconnect express device is located and without manual resetting on a computer system.

Abstract: Embodiments of the present application provide a method in a multi-carrier communications system. The multi-carrier communications system includes a first carrier and a second carrier; a first terminal accesses a wireless network by using a first network device in which the first carrier is located, and is allocated with a radio network temporary identifier C-RNTI; and the method includes: a second network device in which the second carrier is located receives a request message requesting the second network device to allocate the C-RNTI to the first terminal; and when the C-RNTI is allocated by the second network device to a second terminal, the second network device allocates the C-RNTI the same as the C-RNTI of the second terminal to the first terminal, and staggering a communication resource used by the first terminal on the second carrier and a communication resource used by the second terminal on the second carrier.
